The Most Common Furnace Problems and How to Avoid Them

We have been in the HVAC business for a while now and we’ve seen every furnace problem in the book! However, there are some issues that we see a lot more than others. If your furnace is struggling, here are a few things that you can check out. If you’re not comfortable looking at your furnace, these are also what we will check for as soon as we get to your house. 

Clogged Filters

Most filters need to be changed every 1 to 6 months, depending on the type of filter, how often you run your furnace, and a few other specifics of your situation. If you’re not sure how often you should change your filters, our experts can take a look at your system and let you know. 

If you don’t change your filter, your furnace has to work extra hard to get the air that it needs to heat so it can keep your house warm. All of this creates extra wear and tear for the unit and can cause it to break down more often or hit the end of its lifespan faster. 

Thermostat Problems

Before you call us, check your thermostat. Sometimes, it gets bumped, the temperature gets turned down, and people think their furnaces aren’t working. It’s worth checking it out before you call.

Other times, the furnace and the thermostat just aren’t communicating well anymore. In these cases, we can fix the thermostat or replace it with one that will work better for you. A new thermostat could also save you money and give you more control than ever over your comfort systems. 

No Pilot Light

If your pilot light goes out, your furnace won’t work. You can usually check this by looking at the bottom of your furnace for a blue flame. Some furnaces may have their pilot lights located in other areas of the furnace. They will usually be labeled or there will be a diagram on the furnace to show you where to look.

Relighting a pilot light can be straightforward or there can be several steps involved. If you’re not sure how to relight yours, give us a call. We’d be happy to do it for you and show you how to do it for next time. 

Not Enough Gas Supply

If your furnace isn’t getting enough gas, it won’t heat well. Make sure the valve on the gas supply to your furnace is turned all the way on. Sometimes, this gets bumped and turned down. Other times, homeowners think it is safer to have it partially turned off. However, it either needs to be all the way on or all the way off for optimal safety and furnace function. 

If your furnace isn’t working and you can’t figure out why, call us at Thompson today to get an expert HVAC technician to your home ASAP. We’ll get your heat back on fast so you can get comfortable in your Oceanside home again soon!
