Why Does My Furnace Keep Stopping and Starting So Much?

Monday, January 24th, 2022

I recommend to my readers that they keep a steady setting on their thermostats during the day. This is true in winter as well as summer—it helps the HVAC system avoid continual stopping and starting, which drains extra power. For a comparison, I like to sleep on a couch in the sunlight, and if I had to keep getting up and moving every ten minutes because the sunlight kept switching position, I’d use up a lot more energy than if I just could stay in one place. 

But what if you are keeping the thermostat steady, but notice that the furnace is turning on and off rapidly anyway? If your furnace isn’t running for at least 15 minutes at a time before it cycles down, something may be wrong. I’ll go over some possible problems to help you see if you need furnace repair in Knoxville, TN to solve the problem.

You may not know this, but I’m pretty good with number-crunching on a calculator. I need one of those large, old-style calculators because it works better with my large paws, but I can still whip up a good budget when I need to. But when it comes to finding ways to save money on heating bills during the winter, I don’t need a calculator: I already know all the right techniques you can use to cut down on the cost of staying warm! 

I’ve gathered some of my favorite tips on saving during the winter. A few of these will require the assistance of a team of Seymour, TN, HVAC professionals (by which I mean us!). Others you can get started on as soon as the temperatures drop. Let’s dive in.

Did You Know Your Gas Furnace Need Electric Power Too?

Monday, October 4th, 2021

Have you ever thought to yourself, “It’s a good thing I have a gas-powered furnace, because if the electricity goes out during the winter, I’ll still be able to keep warm!” If you have, I’ve got some important news for you: your gas furnace does burn natural gas to heat the air, but it also requires electricity to run. If you lose power to your house, your furnace will also lose power.

I don’t mean to be a downer dog here. I think gas furnaces are great! They’re one of the best ways to provide comfort to homes during our winters. Many of the negative things you hear about gas furnaces just aren’t true! Gas furnaces aren’t super dangerous and they won’t dry out the air in your house. They also need electricity to run, and I want to get into that in detail because the more you know about your furnace, the more you’ll know what help you need when it comes to heating repair in Walland, TN.

How a gas furnace relies on electricity

At one point, gas furnaces did run without electricity … but that was a long time ago when furnaces were massive cast iron creatures that lived in basements, burnt coal, and just let the heat rise up through a network of pipes. (These ancient furnaces have an appropriate name: octopus furnaces.)

Today’s gas furnaces are more complex, as well as more convenient, energy-efficient, and safe—and much of that comes from several electronic controls and devices that help them operate. Here are several ways a gas furnace relies on electrical power:

  • An electronic ignition system ignites the burners. This replaced the old standing pilot light, which was an energy waste and sometimes went out.
  • A furnace uses a blower fan to move air through it and then into the ventilation system. This is often the same fan used for the air conditioning system. 
  • Many of the furnace functions are regulated through an electronic control board. This board handles the ignition, the blower fan, the gas valve, as well as several important safety features.
  • Most homes use a digital thermostat to control the furnace, and these also won’t run in a power outage. 

The moral of my story here is that the electrical parts of a gas furnace may mean the heater won’t run in case of a blackout, but you wouldn’t want a furnace that didn’t have these parts. They make your furnace run better and keep your family safer. 

If you do have a power outage…

I want to drop in a short safety note at the end, in case you do experience a power outage during winter and your gas furnace won’t work. Please don’t attempt to fiddle with the furnace to see if you can get it working. You won’t be able to, and you may interfere with the safety features that shut off gas flow in case of an outage. If your furnace won’t come back on when power is restored, please call our professionals to investigate. They’ll make sure that all safety mechanisms are working and your furnace will run without hazard.

Stay warm and safe,

Time for the Annual Furnace Performance Overview!

Monday, March 22nd, 2021

When winter comes to an end, it’s time to think about how your furnace managed over the season. This will help you know if you need any important furnace service in Knoxville, TN (such as repairs or a full replacement) during the coming stretch of the year when you won’t need to rely on your heater daily.

This is when I get out my pen and help you go through a checklist “performance overview.” I’d love it if I could tuck the pen behind my ears, but I don’t have stand-up ears like German Shepherds, so I’ll just have to grip the pen in my mouth when not using it. Anyway, let’s get into this informal overview. 

Please note: This casual exercise is not a substitute for annual heating maintenance in fall. When you need actual heating work done, you’ll want our pros to be there to do it!

Combustion Analysis—It’s Important, But Not Everyone Does It!

Monday, February 22nd, 2021

If I wanted to go on the road as the World’s First and Best Psychic Dog, I know just the trick to pull to amaze my viewers: my assistant would ask someone in the audience to stand up, and I would announce (through special barking code) that they use a gas furnace to heat their home. And I’d be right … most of the time. (If I’m wrong, I’ll just tell them they may have a gas furnace in the future.) 

So I’m guessing you have a gas furnace. And if you do, you’ll need occasional combustion analysis for it to help make sure it’s keeping your family safe. Our team is great at combustion analysis, and we’re proud of that because far too many other HVAC contractors don’t do it at all!

Olive Explains: Why Your Furnace’s Burners Aren’t Lighting

Monday, January 25th, 2021
gas-jets-in-furnace

Here’s an irritating problem: you set your thermostat for something comfy during winter. I recommend 68°F, even though my nice fur coat lets me set it lower than you would. It’s a cold day, so that means setting the thermostat to that temperature will cause the furnace to come on. But it doesn’t. The fan might turn on, but not warm air. When you go to the furnace, you discover that the customary blue glow from the burners isn’t there—they haven’t ignited. What’s going on?

Well, I can list a few possibilities…

A Few Things to Know Running Your Heat Pump in Winter

Monday, January 11th, 2021

Did you welcome a new addition to your house during the last year—a heat pump? Congratulations! We’re all fans of heat pumps around here, especially the Onyx models we install, which are ideally suited for the winters in East Tennessee. 

But if this is your first winter with a heat pump, there are a couple of things I’d like you to know. If you’ve already run it during the summer, you noticed it didn’t act any different than an AC. That’s just as it should be! But as you change the heat pump over to heating mode for winter, there are a few differences to get used to. After all, a heat pump isn’t a furnace and doesn’t provide heat the same way. Here’s “Olive’s List of Useful Things to Know” about your heat pump in winter.

Trying to Heat Your Home “Faster” With the Thermostat? That Won’t Work

Monday, December 14th, 2020

We’ve all been there on a winter night: The house feels awfully cold, and you want to get the rooms warmed up as fast as you can. You look at the thermostat on the wall and see that it can go as high a 90°F. That’s far too hot, of course, but if you crank the thermostat up that high, it will at least mean the house will warm up faster. The heat will come roaring out of the vents!

Except … that’s not how home heating works. And trying to get “faster” heating by pushing the thermostat up so high can be bad news for an HVAC system in Knoxville, TN
