The $5000 HVAC rule is a simple guideline that helps homeowners decide if repairing or replacing an aging heating or cooling system makes more financial sense. It is not a strict rule or an industry standard. Instead, it combines the age of your equipment with the estimated repair cost to provide a quick way to evaluate your options. This guide explains how the formula works, when it is useful, and why a professional inspection is still an important part of the decision.

What the $5000 Rule Means

The idea behind the rule is straightforward.

Multiply the age of your HVAC system by the estimated repair cost. If the total exceeds 5,000, replacement is frequently the better long-term investment. If the number stays below 5,000, repairing the system may still make sense.

The formula is intended to provide a starting point. It does not account for every factor that affects the condition of an HVAC system.

How to Calculate It

The calculation only takes a few seconds.

  1. Determine the age of your HVAC system.
  2. Obtain a professional repair estimate.
  3. Multiply the age by the repair cost.

For example:

12 × 500 = 6,000

Because the result is greater than 5,000, replacing the equipment may be the more practical choice.

The formula helps homeowners compare today's repair expense with the remaining expected life of the equipment.

Why Homeowners Use This Rule

Major HVAC repairs can be difficult to evaluate without a simple reference point.

The $5000 rule gives homeowners a quick way to decide if investing more money into an older system is worthwhile. It is especially helpful when equipment has experienced multiple breakdowns or is approaching the end of its expected service life.

Rather than making a decision based only on the repair estimate, homeowners can consider both the age of the equipment and the amount of money required to keep it operating.

When HVAC Repair May Still Make Sense

The formula does not automatically mean replacement is the right answer.

Repairs are frequently worthwhile when:

A professional inspection can determine if the repair is likely to restore normal operation without leading to additional expenses in the near future.

When HVAC Replacement May Be Smarter

As HVAC systems age, larger repairs become more common.

An older system that requires expensive repairs, struggles to maintain comfortable temperatures, or experiences repeated breakdowns may be a better candidate for replacement. If your air conditioner is showing multiple signs you need to replace your AC, investing in new equipment may provide greater value than continuing to repair aging components.

The same concept applies to heating equipment. In some situations, furnace replacement becomes the more practical solution when repair costs continue increasing.

Other Factors to Consider

The $5000 rule is only one piece of the decision.

Other considerations include:

An HVAC technician can evaluate all of these factors before recommending repairs or replacement. The $5000 rule is a useful starting point, but a professional inspection provides a more complete picture of your system's condition.

If your AC is blowing hot air and turned a comfortable home into a warm one, the problem could be as simple as an incorrect thermostat setting or as serious as a mechanical failure. Airflow restrictions, refrigerant problems, electrical issues, and damaged components can all prevent your air conditioner from cooling properly. This guide explains the most common causes, what you can check yourself, and when it's time to call an HVAC professional.

Thermostat Settings

Start with the thermostat before assuming something is wrong with your air conditioner.

Make sure the thermostat is set to "Cool" instead of "Heat" or "Fan." If the fan is running without the cooling cycle, the system will circulate room-temperature air through the vents.

If the settings are correct but the system still isn't cooling, replace the thermostat batteries if applicable. Faulty wiring or a malfunctioning thermostat can also prevent the cooling system from operating correctly.

Dirty Air Filter

A clogged air filter restricts airflow throughout your HVAC system.

When enough air cannot move across the evaporator coil, cooling becomes less effective, making it seem like the air conditioner is blowing warm air even though it continues running.

Replacing the air filter is one of the easiest maintenance tasks homeowners can perform. A clean filter improves airflow and helps your system operate more efficiently.

Low Refrigerant

Refrigerant carries heat from inside your home to the outdoor unit. When refrigerant levels become too low, the system cannot remove enough heat to cool your home.

Low refrigerant almost always indicates a leak somewhere in the system. Simply adding refrigerant without repairing the leak will not solve the problem.

Because refrigerant must be handled safely and accurately, diagnosing leaks and restoring the proper charge should always be left to a licensed HVAC technician.

Outdoor Unit Problems

The outdoor condenser releases the heat collected from inside your home. If it stops operating, the cooling cycle cannot continue.

Several issues can affect the outdoor unit, including:

If the outdoor unit is not running while the indoor blower continues operating, professional service is recommended.

Frozen Evaporator Coil

Ice on the evaporator coil prevents the system from absorbing heat properly, causing warm air to come from the vents.

Frozen coils are commonly caused by restricted airflow, dirty filters, or low refrigerant. If you notice ice on the refrigerant lines or indoor equipment, turn the system off and allow it to thaw before restarting it.

If the coil freezes again after thawing, additional inspection is needed to identify the underlying problem.

Compressor or Electrical Issues

The compressor circulates refrigerant throughout the air conditioning system and is one of the most important cooling components.

Electrical failures, damaged wiring, or a failed capacitor can prevent the compressor from operating correctly. When this happens, the blower may continue moving air through the home while little or no cooling takes place.

These repairs require specialized testing and should be handled by a qualified HVAC technician.

Signs the Problem Needs a Professional HVAC Technician

Some warning signs point to problems that extend beyond a dirty filter or thermostat adjustment.

Call an HVAC professional if you notice:

Persistent cooling problems can lead to additional system damage if left unaddressed.

What to Check Before Calling

Before scheduling service, perform a few simple checks.

If basic troubleshooting doesn't solve the problem, a professional inspection can identify the cause before additional damage occurs. If testing shows the system has reached the end of its service life, reviewing signs you need to replace your AC can help you understand your next steps, including a new central AC system.

An air conditioner freeze up is a common sign that something is preventing your cooling system from operating correctly. Problems with airflow, refrigerant, or mechanical components can allow ice to form on the evaporator coil, reducing cooling, increasing energy use, and placing extra strain on the system. This guide explains the most common causes of an AC freeze-up, warning signs to watch for, and when it's time to contact an HVAC professional.

Low Airflow

Restricted airflow is the leading cause of an air conditioner freezing. Your evaporator coil depends on a steady flow of warm indoor air to absorb heat. When that airflow slows down, the coil becomes too cold and moisture in the air begins to freeze.

Several problems can reduce airflow, including:

Correcting airflow problems early helps restore normal cooling and prevents additional strain on your HVAC system.

Dirty Air Filter

A clogged air filter is one of the simplest and most preventable causes of a frozen air conditioner.

As dust and debris collect on the filter, less air reaches the evaporator coil. Without enough warm air moving across the coil, ice can begin forming during normal operation.

Checking your filter every month and replacing it when it becomes dirty is one of the easiest ways to reduce the chance of an air conditioner freeze up.

Low Refrigerant

Low refrigerant changes the pressure inside your air conditioning system, allowing the evaporator coil to become colder than it should. Moisture then freezes on the coil and gradually builds into thicker layers of ice.

Refrigerant does not wear out over time. If levels are low, the system likely has a leak that needs professional repair. Simply adding more refrigerant without repairing the leak will not solve the problem.

Dirty Evaporator Coils

Evaporator coils collect dust over time, especially if air filters are not replaced regularly.

When dirt covers the coil, heat transfer becomes less effective. The system struggles to absorb enough heat from your home, increasing the chance of ice forming while reducing overall cooling.

Routine maintenance includes cleaning the evaporator coil so the system can continue operating efficiently.

Blower or Fan Issues

The blower motor pushes air across the evaporator coil and throughout your home.

If the blower motor is failing or the fan is not moving enough air, the coil can become too cold and begin freezing. Weak airflow may also cause uneven temperatures, longer cooling cycles, and reduced comfort throughout the house.

These problems require a professional inspection to identify the failed component and restore normal airflow.

Thermostat or System Problems

Incorrect thermostat settings or equipment malfunctions can contribute to freeze-ups.

Running an air conditioner during unusually cool outdoor temperatures can create conditions where the evaporator coil becomes too cold. Faulty sensors or control problems may cause the system to continue running longer than intended, increasing the likelihood of ice buildup.

Signs Your AC Is Freezing Up

Several warning signs appear before the system stops cooling completely.

Watch for:

If these symptoms continue, it's time to schedule a professional inspection before additional damage develops.

What to Do if Your AC Freezes Up

If your air conditioner freezes, turn the system off and allow the ice to thaw completely. Running the equipment while ice is present can place additional strain on the compressor and other components.

While the system is thawing, inspect the air filter and make sure supply vents remain open and unobstructed. If the problem returns after restarting the system, professional service is recommended to determine whether airflow restrictions, refrigerant leaks, or mechanical failures are responsible.

How to Prevent AC Freeze-Ups

Regular maintenance is the best way to reduce the chance of future freeze-ups.

Simple preventive steps include:

Routine inspections through Tiger's Club membership help identify airflow restrictions, refrigerant issues, and worn components before they develop into larger repairs.

If your system continues experiencing repeated freeze-ups, it may be time to review signs you need to replace your AC or determine if central AC replacement is the better long-term solution.

What is a mini split air conditioner? A mini split is a ductless heating and cooling system that conditions individual rooms instead of sending air through ductwork. These systems are popular for room additions, garages, finished basements, and other spaces where installing ducts is not practical. Many models provide both heating and cooling, making them a year-round comfort solution. This guide explains how mini splits work, where they are used, and how to decide if one is the right choice for your home or business in Central Illinois.

Ductless Mini Split Air Conditioner 101

A mini split system has two main components. The indoor air handler mounts on a wall, ceiling, or floor inside the room, while the outdoor condenser sits outside the building. Refrigerant lines connect the two units, allowing them to move heat between the indoors and outdoors.

Unlike a traditional forced-air system, a ductless air conditioner delivers conditioned air directly into the room where it is installed. Each indoor unit operates independently, allowing homeowners to cool or heat specific areas without relying on a network of ducts.

Because they focus on individual spaces, mini split HVAC systems are a common choice for homes that need additional cooling in one area instead of replacing the entire HVAC system.

How Mini Splits Work

Mini split cooling works by transferring heat instead of creating cold air. The indoor unit absorbs heat from the room, and refrigerant carries that heat to the outdoor condenser, where it is released outside. The cooled refrigerant then returns indoors to repeat the process.

Most systems are controlled with a handheld remote or a wall-mounted thermostat, making temperature adjustments simple. Since each indoor unit operates independently, different rooms can be set to different temperatures. This zoning gives occupants greater control over comfort without affecting the rest of the building.

Professional ductless mini split installation includes selecting the correct equipment size, placing the indoor and outdoor units, and routing refrigerant lines for dependable operation.

Benefits of a Ductless Mini Split System

Mini split systems offer several advantages for homes and businesses where ductwork is unavailable or unnecessary.

Homeowners comparing different cooling systems may find it helpful to review what size is your AC before deciding between a mini split and a traditional central air system.

Common Uses for Mini Splits

Mini splits solve comfort problems in spaces that existing HVAC systems do not serve well.

They are frequently installed in room additions, enclosed patios, garages, bonus rooms, home offices, and older homes that were never built with ductwork. A ductless system can add cooling to these areas without the cost and disruption of extending existing ducts.

Mini splits are sometimes installed alongside an existing HVAC system to improve comfort in rooms that stay warmer than the rest of the home during the summer.

Ductless Mini Split vs. Central Air

Mini splits and central air conditioners both cool your home, but they serve different purposes.

A mini split conditions individual rooms or zones. Central air distributes cooled air throughout the home using ductwork, making it a practical choice for houses that already have a complete duct system.

If your current cooling system is reaching the end of its service life, reviewing signs you need to replace your AC can help you understand when replacement becomes the better option.

Homeowners comparing ductless systems with central AC should consider how they use each space, the presence of existing ductwork, and whether they want whole-home cooling or independent room-by-room temperature control.

Is a Ductless Mini Split Right for You?

A ductless mini split is a good fit for homes and businesses that need comfort in specific rooms without adding ductwork. The right system depends on the size of the space, how the building is used, and the existing HVAC equipment.

Our HVAC professionals can evaluate your property and recommend the cooling system that best matches your needs. Tiger serves customers throughout Central Illinois, and you can visit our service areas to see the communities we serve.

A sump pump prevents water from flooding a basement or crawl space by collecting water in a pit and pumping it away from the home.

For homes across Central Illinois, a sump pump can be an important defense against heavy rain, snowmelt, and saturated soil. Tiger has been serving the region since 1993, helping homeowners with sump pump installation, repair, and maintenance.

What Is a Sump Pump?

A sump pump is a device installed in a sump pit, which is a basin located in the lowest part of a basement or crawl space.

As water gathers around the foundation, it flows into the pit instead of collecting on the floor. When the water reaches a certain level, the pump moves it through a discharge pipe and away from the home.

Sump pumps are common throughout the Midwest because spring storms and wet soil can put extra pressure on foundations. Without a way to move that water away, basements and crawl spaces become vulnerable to moisture problems.

How Does a Sump Pump Work?

The process happens automatically.

  1. Water enters the sump pit.
  2. The water level rises inside the basin.
  3. A float switch or sensor detects the water level.
  4. The pump turns on.
  5. Water is pushed through a discharge pipe away from the house.
  6. The pump shuts off once the water level drops.

Most homeowners never notice the system working until a heavy storm arrives. When the pump is operating correctly, it removes water before it becomes a larger problem.

Types of Sump Pumps

Pedestal Sump Pump

A pedestal sump pump has the motor mounted above the sump pit.

Because the motor stays out of the pit, repairs and maintenance are generally easier. These systems are frequently found in older homes and are sometimes chosen because of their lower upfront cost.

The tradeoff is that pedestal pumps tend to be louder and less discreet than other options.

Submersible Sump Pump

A submersible sump pump sits inside the sump pit.

These pumps are designed to operate underwater and are generally quieter because the motor remains below floor level. They are commonly installed in homes that deal with larger amounts of groundwater or frequent storms.

Submersible pumps are a common choice for homes that have experienced sump pump flooding because they are designed to handle heavier water loads.

Why Sump Pumps Are Important

Water around a foundation can create expensive problems.

A working sump pump helps limit:

In parts of Central Illinois where heavy rain and saturated soil are common, a sump pump provides an extra layer of protection against unwanted water entering the home.

Signs Your Sump Pump Needs Repair or Replacement

Like any mechanical system, sump pumps wear out over time.

Watch for these warning signs:

Any of these warning signs should be checked before the next storm. Catching a problem early is a lot easier than dealing with water in the basement after the pump stops working.

When to Call a Professional Plumber

A sump pump that stops working doesn't always tell you why it failed.

The pump, discharge line, float switch, electrical connection, and drainage path all need to work together. Problems in any one of those areas can affect performance.

If a new system is needed, proper plumbing installation and discharge routing are important. A licensed plumber can evaluate the system, identify the source of the problem, and recommend the right solution.

If you're looking into how to install tankless water heater systems, it helps to understand what's involved before the work begins. Even if you decide to hire a professional, knowing the basic steps can make it easier to compare options and ask the right questions.

Tankless water heaters heat water as it moves through the unit instead of storing it in a tank. The installation process includes plumbing connections, venting, gas or electrical work, and local code requirements. Tiger has been serving Central Illinois since 1993 and installs tankless systems for homeowners who want the job done safely and correctly.

How a Tankless Water Heater Works

A tankless water heater heats water only when you need it.

When someone turns on a hot water faucet, shower, or appliance, water flows through the unit and is heated before reaching the fixture. Since there is no storage tank, the system takes up less space and continues producing hot water as long as it stays within its capacity.

Tankless systems are popular in Illinois homes because they provide a steady supply of hot water without the space required for a large storage tank.

Key Steps in a Tankless Water Heater Installation

Choose the Right Location

Picking the right location is one of the first steps.

The unit should be placed near existing water lines, gas service, and venting whenever possible. It also needs enough room around it for safe operation and future service.

Indoor and outdoor units have different installation requirements, so check the manufacturer's instructions before choosing a location.

Turn Off Utilities and Remove the Old Unit

Before removing the old water heater, turn off the gas, water, and electrical supply connected to the system.

The tank should be drained completely before disconnecting any plumbing. Water heaters are heavy, so use caution during removal.

Once the old unit is out of the way, damaged pipes, worn valves, or other plumbing problems are easier to spot.

Mount the Tankless Unit

Most tankless water heaters mount directly to a wall using a bracket supplied by the manufacturer.

The unit should be level and secured according to the installation instructions. Placement matters because it affects venting, pipe routing, and future access if repairs are needed.

Connect Water, Gas, and Venting

This is the step where most DIY projects become more challenging.

The cold-water inlet and hot-water outlet must be connected using approved materials. Some tankless systems require larger gas lines than traditional water heaters.

Gas units also require proper venting. Poor venting can create serious safety concerns, so installation instructions should be followed carefully.

Check for Leaks and Start Up the System

After all connections are complete, inspect the entire system.

Check water lines for leaks, verify gas connections, and follow the startup instructions provided by the manufacturer. Once the system is running, test hot water at several fixtures throughout the home.

Before calling the job finished, inspect everything one final time to make sure the system is operating correctly.

When to Call a Professional for a Tankless Water Heater Installation

Installing a tankless water heater is not always a simple replacement project.

Some installations require:

Mistakes during installation can create safety concerns, affect system performance, and create warranty issues.

If the project involves gas piping, electrical upgrades, or significant plumbing work, a licensed plumber should inspect the installation before work begins.

Flushing your water heater can help remove sediment, improve efficiency, reduce rumbling noises, and extend the life of the tank. It's one of the most useful maintenance tasks homeowners can perform on a traditional storage water heater.

In many cases, flushing a water heater is a manageable DIY project. However, if you discover leaks, rust, corrosion, or other safety concerns during the process, it's best to stop and call a professional. Tiger has been serving Central Illinois since 1993 and can help with maintenance, repairs, and replacement when needed.

What You'll Need Before You Start

Before getting started, gather a few basic items:

You'll also need to determine if the unit is gas or electric.

Before draining the tank, turn off power to an electric unit or shut off the gas supply on a gas water heater. Safety comes first.

Step-by-Step: How to Flush a Water Heater

Turn Off the Power or Gas

The system should be completely shut down before draining begins.

For electric water heaters, turn off the breaker supplying power to the unit. For gas models, turn the gas control valve to the appropriate off position.

Shut Off the Cold Water Supply

Locate the cold water shutoff valve above the tank and close it.

This prevents new water from entering the tank while you are draining it.

Attach a Hose and Drain the Tank

Connect a garden hose to the drain valve near the bottom of the tank.

Run the hose to a safe drainage location. Keep in mind that the water can be very hot. Avoid draining near walkways, landscaping, or areas where hot water could cause damage.

Open the drain valve carefully and allow the tank to empty.

Flush Out the Sediment

Once the tank has drained, briefly turn the cold water supply back on.

This helps stir up remaining sediments at the bottom of the tank so they can be flushed out through the hose. Continue the process until the water leaving the tank appears clear.

Hard water build up can leave a surprising amount of sediment behind, especially in older systems.

Refill the Tank and Restore Power

Close the drain valve and disconnect the hose.

Turn the cold water supply back on and allow the tank to fill completely. Check around the drain valve and nearby connections for leaks.

Once the tank is full, restore power or gas to the unit. It may take some time before hot water is available again.

How Often Should You Flush a Water Heater?

Most homeowners should flush their water heater once a year.

Homes with hard water, larger households, or higher hot water usage sometimes benefit from more frequent flushing. Regular water heater maintenance helps reduce sediment accumulation and gives technicians an opportunity to identify developing issues before they become major repairs.

Many homeowners also use a maintenance membership program to stay on schedule with annual maintenance.

When to Call a Professional Water Heater Plumber When Flushing Isn't Enough

Flushing removes sediment, but it won't fix every water heater problem.

Contact a professional if you notice:

These signs can indicate problems that require water heater repair or even a water heater replacement rather than maintenance alone.

If you're in Springfield and run into a problem during the process, our licensed plumbers can evaluate the system and determine the next step.

Knowing how to clean an air conditioner can improve airflow, cooling performance, and indoor air quality. A few basic maintenance tasks are safe for most homeowners and can help keep the system operating properly throughout the cooling season.

That said, not every part of an air conditioner should be cleaned by a homeowner. Some components require specialized tools and training. If you run into a problem beyond basic maintenance, Tiger's technicians can help determine if the system needs cleaning, repair, or replacement.

What You Can Safely Clean Yourself

Replace or Clean the Air Filter

If you're wondering how to clean an air conditioner, start with the filter.

A dirty filter restricts airflow and forces the system to work harder than necessary. It can also contribute to poor cooling and higher energy usage.

Most filters should be checked regularly and replaced based on household conditions. Homes with pets, allergies, or higher dust levels often require more frequent filter changes.

A clean AC filter is one of the simplest ways to support system performance.

Clear Debris Around the Outdoor Unit

The outdoor condenser needs unrestricted airflow.

Leaves, grass clippings, weeds, and debris can collect around the unit and reduce efficiency. Keep the area around the condenser clear and trim back vegetation as needed.

Avoid bending the aluminum fins and do not spray water directly into electrical components while cleaning.

Clean Return Vents and Supply Registers

Dust buildup around vents and registers can affect airflow throughout the home.

Vacuum return vents and wipe down supply registers as needed. It's also a good idea to make sure furniture, rugs, and other items are not blocking airflow.

What Requires Professional AC Cleaning

Cleaning the Evaporator and Condenser Coils

Air conditioner coils collect dirt over time.

When buildup covers the coils, heat transfer becomes less effective and cooling performance suffers. Dirty coils can also contribute to frozen components and airflow problems.

This type of cleaning is best left to professionals because the coils can be damaged if handled improperly. During an AC maintenance visit, technicians can inspect and clean these components safely.

Cleaning the Drain Line and Drain Pan

The condensate drain line removes moisture created during the cooling process.

Over time, algae, sludge, and debris can build up inside the line. A blockage can lead to water leaks, overflow issues, or system shutdowns.

If the drain line continues clogging, professional service is the best way to identify the cause.

Checking Electrical and Mechanical Parts

Technicians inspect motors, capacitors, electrical connections, and other components for signs of wear. Catching weak parts early can prevent unexpected breakdowns during periods of heavy summer use.

Signs Your AC Needs More Than a Cleaning

Watch for these warning signs:

These issues can indicate problems that cleaning alone will not solve. In some situations, AC replacement becomes a better option than continuing to repair aging equipment.

How Often Should You Clean Your AC?

Filters should be checked regularly throughout the cooling season. The rest of the system benefits from professional service at least once a year.

A spring AC tune up gives a technician an opportunity to inspect components, clean critical areas, and identify developing issues before summer temperatures arrive.

Many homeowners also choose a Club membership program to stay on schedule with maintenance and inspections.

In Central Illinois, long cooling seasons and heavy summer usage make routine service especially important.

Heat pump services often start with simple questions from homeowners who are not completely sure what type of system they have. A heat pump can look almost identical to a standard AC system from the outside, which causes confusion in a lot of Central Illinois homes.

The easiest way to identify one is by checking the thermostat settings, the outdoor unit label, and the way the system operates during colder weather. This guide walks through a few quick ways to tell if your home uses a heat pump and when it makes sense to have the system inspected professionally.

Tiger Plumbing has served Central Illinois since 1993 with licensed HVAC technicians, plumbers, and electricians who help homeowners keep heating and cooling systems operating safely year-round.

Check The Thermostat

The thermostat gives one of the clearest signs that a home uses a heat pump.

Look for settings like:

A standard furnace system usually shows simpler modes like:

If the thermostat includes emergency heat settings, there is a strong chance the home uses a heat pump system with backup heating.

If you are unsure what system you have, take a photo of the thermostat screen before calling for heat pump services in Springfield during winter heating problems.

Look At the Outdoor Unit Label

Most outdoor units include a manufacturer label or model number plate attached to the side of the equipment.

In some cases, the label directly says:

If the wording is unclear, search the model number online. Most manufacturers list system type information on their websites.

A lot of homeowners assume every outdoor AC unit works the same way, but a heat pump handles both heating and cooling from the same outdoor system.

Find The Reversing Valve

A reversing valve is one of the main components that separates a heat pump from a standard air conditioner.

This valve allows the system to switch between:

The valve usually sits near the outdoor units refrigerant lines.

If you are not comfortable opening the panel or inspecting HVAC components directly, a technician can confirm the system type quickly during a service visit.

Notice How the System Runs in Winter

A heat pump continues running outside during cold weather because it pulls heat from outdoor air and transfers it into the home.

That surprises a lot of homeowners who expect the outdoor system to stay off during winter.

You may also notice:

Homes around Bloomington and neighborhoods near Constitution Trail often rely on heat pumps during milder winter stretches before backup heat takes over during colder temperatures.

Dual Fuel Systems

Some homes use a dual fuel setup that combines a heat pump with a furnace backup system.

That setup creates confusion because the home may use:

The thermostat and outdoor equipment may show signs of both systems depending on the temperature and fuel source.

This is one reason homeowners comparing a heat pump vs AC setup sometimes struggle to identify what equipment they have installed.

Why It Matters – Differences between Heat Pump vs. HVAC

Knowing what system is installed helps with:

Correct identification also helps technicians diagnose heating problems faster during service calls.

For example, a home using a heat pump may switch into emergency heat during extremely cold weather or when the outdoor system stops operating correctly.

That is different from a traditional furnace setup, where heating and cooling equipment work separately.

Homes near Laura Bradley Park and older neighborhoods around East Peoria often have mixed heating setups from different installation periods. That is one reason homeowners start researching heat pump installation in Peoria before replacing aging equipment.

When To Call a Professional Plumber

If the thermostat settings, outdoor unit label, and winter operation still do not make the system type clear, a technician can identify it quickly.

Tiger Plumbing provides HVAC service Illinois homeowners can call for system inspections, repairs, maintenance, and heat pump installation.

If the system stops heating during freezing temperatures, emergency HVAC service may also be necessary to restore safe indoor temperatures before pipes or equipment become vulnerable to cold weather damage.

A technician can also confirm if the home uses:
