As we know from our three decades of experience HVAC, furnaces can break down for a whole host of reasons. That’s why we recommend regular maintenance and repair, before it gets to the point where your furnace actually breaks, and you have to call in a professional.

But, the chances are that if you’re reading this, you didn’t heed our sage advice… Oh, well. Your furnace has broken down- and here are a few of the reasons why it might have. Starting with…

Furnace repair Aurora CO: Dust, dirt and grime clogging the air filter

All furnaces, from the state of the art one your neighbor has to the rickety and disgusting one in your basement have an air filter. This is so that the air which reaches the ducts, and then circulates around your home, is nothing if not clean and fresh. If you didn’t have an air filter, you would probably end up coughing and spluttering like you’re sat at a campfire.

Needless to say, air filters are vital to your furnace’s energy efficiency. If it becomes too dirty, too full of dust and grime, then your furnace just won’t be able to heat your home. And in the very worst case scenario, the backed up air can cause all sorts of havoc inside the furnace itself. It’s best to have your filter replaced regularly to stop that from happening. A dirty air filter is a useless air filter. Not only can it make your furnace less efficient, but it can stop it from working completely, given enough time.

Furnace repair Aurora CO: There’s a problem somewhere along the gas line

Of course, this only applies to you if your furnace runs on gas. But if it does- and most do- then one of the most common causes of breakdown is a problem in your gas line. In extremely rare cases, this could be that the gas pipe has become blocked, although we’ve never seen it happen. Instead, it’s normally because of a gas leak, caused by damage to the exterior of the pipe. Needless to say, this is an extremely dangerous situation to be in. The first sign that you may have a gas leak is that you smell gas.

Another sign that your furnace or boiler could be leaking gas is if the pilot light won’t stay lit. It’s commonly the case that rather than the entirety of the gas leaking from the pipe, only some of it does. When that’s the case, your pilot light might be weaker than usual. You may also notice that your heating doesn’t work as well as it used to, or that you don’t have as much hot water as you need. If you smell gas, or have reason to suspect that there may be a gas leak for any other reason, you should call a professional immediately.

Furnace repair Aurora CO: The ignition in your furnace might be faulty

Like any sort of engine or device that needs fuel to run, furnaces need to ignite the fuel so that they can burn it. This is achieved by the ignitor, which is most often a small device which looks like an oversized key. Over time, the ignitor can become singed and cracked, sort of like a worn out spark plug. This stops your furnace from being able to burn fuel, so it will completely stop working.

Fortunately, it’s quite easy to replace the ignitor in a furnace. All you need is to know what you’re doing! A simple resistance test can tell whether the ignitor is working as it should.

Furnace repair Aurora CO: There may be a mechanical fault inside your furnace

There are a number of mechanical parts which are essential to your furnace’s operation. These include fans, motors and belts, bearings and seals, all of which can break down either due to wear and tear, corrosion, or shock damage. When a motor breaks down or the fan won’t turn, your pilot light will still be on and your furnace will still be creating heat, but it won’t be able to send that heat around your house. If some of the bearings and seals have come loose or worn away, this will simply lower your furnace’s efficiency. While you’ll definitely notice if your furnace isn’t heating your home, energy efficiency loss is hard to notice, so you should have your furnace inspected regularly.

Furnace repair Aurora CO: It could be the fact that your furnace is simply too old

Last, but not least, your furnace might just be old. There’s only so much we can do to fix a furnace in which almost everything is worn and broken.
