Sources of Energy Waste and How to Fix Them

Published: November 6, 2020

The first step when solving a problem is to identify it. Your energy use is no different. To save energy, you need to first figure out where it is being wasted.

Here are the six most common reasons why your HVAC system is consuming more energy than it should and how to fix them.

Inefficient furnace

Your furnace is your home’s heat source and the first place energy can be lost. This is normally through poor burner performance, a low-efficiency design, or age. Call in a professional to check all aspects of your system before regular use. If you decide it is time for an upgrade, look into high-efficiency options for even better performance.

Dirty filters

In addition to poor air quality, a clogged filter reduces the amount of air your fan can distribute. This makes your furnace work even harder to maintain your home’s temperature. Clean or replace your furnace filter regularly to minimize this unnecessary source of energy waste and save money.

Dirty ductwork

Build-up in your ductwork also reduces the airflow into your home, making your furnace consume more energy as it works harder to heat your home. If you’re a smoker or have pets, it is important to have your ductwork cleaned regularly.

Save energy by adjusting your thermostat

Non-programmable thermostat

You might be vigilant enough to lower your home’s temperature whenever you go out or just before bedtime. In that case, you are saving energy based on your daily habits. If like most people, you rush out the door every day without a thought about keeping your empty house just a little cooler, a programmable thermostat might be exactly what you need. Consider replacing your thermostat to allow you to save this energy.

Air leakage

Ductwork that is not properly sealed can leak air into your ceiling or underfloor space, wasting heat that should be used to heat the space you occupy. As with clogged ductwork, this reduced airflow translates into an overworked furnace that consumes more energy. If you suspect leaky ductwork, have a professional seal off joints that can cause these energy losses.

Poor insulation

Whether it is hot water piping, refrigerant piping, or ductwork in unheated spaces, having the right insulation prevents heat from being lost to the surrounding air. Wherever you have a large temperature difference between what is inside and outside a duct or pipe, you need to have it insulated. If you suspect that parts of your HVAC system are uninsulated, or if the insulation is disintegrating, have a professional inspect it and make the necessary repairs.

"My families a/c went out randomly today. I went around the house troubleshooting what I could. It got to the point where we had to call someone. We called the first places that showed up on google. Most places either wanted tons of money just for diagnostics, or couldn’t come out today. We called Tiger they went over the cost and they got someone out to our house in 45 minutes. Josh Moravec was our tech and was super professional, kind and intelligent. He was here for about 15 minutes before he figured out our issue. He went over in depth the cost and verified everything was good before getting started to resolve it. There was no pressure to buy the service if we didn’t want to. He went back down and in 15 minutes the a/c was running strong! He asked if we had any questions and then was on his way! He was great with our kids, very polite and courteous of me and my wife. He answered all our questions, and the price was more than reasonable. We definitely recommend Tiger, and make sure you ask for Josh Moravec if you can!"
