Modulating Furnace Benefits

Blue Furnace Burners

We have come a long way in heating since the early days of gathering wood for a fireplace. Nowadays, we can be grateful for gas-fired furnaces that keep us warm. And with the creation of the modulating furnace, there’s even more benefits.

Furnace technology itself has developed over the years. If yours is nearing the end of its life, call us at Tiger to have it replaced! Continue below to learn more about the benefits of modulating gas furnaces.

Types Of Furnaces

Furnaces can be classified according to their burner operation. There are three main categories: single-stage, two-stage, and modulating. 

Single stage furnaces are either on or off. When the thermostat temperature drops below the set point, the furnace comes on and runs until the temperature reaches the desired level. Then it shuts off until the temperature drops again. 

Standard Furnace

Two stage furnaces operate at partial capacity and full capacity depending on the heating requirements. This allows your furnace to use less energy when less heat is needed. Its efficiency is slightly better than that of a single stage furnace. 

Modulating furnaces vary the output to match the heating demands. This means they don’t come on and off every time the temperature drops. They run almost continuously, just heating in smaller increments. This has several benefits.

Modulating furnaces keep your home at a steady temperature

Single-stage furnaces can vary your home’s temperature by as much as six degrees. So while they are capable of providing the right amount of heat, that heat isn’t always consistent. You end up shivering as you wait for the furnace to come back on. Modulating furnaces maintain your home’s temperature by constantly providing the right amount of heat.

You Save Energy With a Modulating Furnace

Even though modulating furnaces run for longer hours than a standard furnace, they rarely run at full capacity. This decreases the overall amount of fuel used. Single stage furnaces also consume more energy at startup, further increasing their consumption. Modulating furnaces don’t have this issue, they slowly ramp up and down as needed. 

Improved Air Quality

Having your air flow continuously through your filters allows for cleaner air. You can choose to keep your fan running continuously for a single stage furnace, but it consumes more electricity than a modulating furnace.

We definitely recommend Tiger!
"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!"
