4 Common Furnace Problems

A well-functioning furnace will be capable of keeping your home at a comfortable temperature throughout the cold-weather months. Chances are that when your furnace is working normally, you won’t even have to think about it – it will just switch on when your home needs heat. 

Ft. Collins furnaces are made to have long lifespans. Usually, if there’s an issue with the furnace, it can be resolved fairly easily. It’s helpful to know the common furnace problems that you may face as a homeowner so that you can quickly get the appropriate repairs – and warm your home back up!

The Furnace Isn’t Heating The Home

Your furnace function virtually exclusively to move warm air throughout your living spaces so that your home is comfortable when the weather is cold. One of the most common furnace problems occurs when the furnace is simply not serving this purpose. If your furnace is on but not producing heat, you should check in on a few usual culprits before calling in the furnace repair specialists. 

  • The fan setting

If your furnace’s fan setting is on, it can prevent heat from permeating your home. This is because with the fan setting on, air from the furnace will blow throughout your home, but the air may not be heated. This can prevent your home from reaching (and staying) a comfortable temperature.  

  • Clogged filter

If your furnace isn’t heating your home, another issue to look for is in the filter. If the filter is clogged or dirty, the furnace won’t function effectively. Dirt, dust, and debris will build up in your furnace’s filter over time, making it important to change the filter periodically. If you have pets, the pet fur will make your furnace’s air filter clog more quickly. A new filter could be the answer to your furnace not producing heat, and if that’s the case, all you’ll need to do is switch it out for hot air. 

We recommend that you have the filter changed before the start of the winter season. This will ensure that your furnace will be ready to produce heat for your home when the cold temperatures strike! 

The Furnace Won’t Turn On Automatically

If your furnace isn’t turning automatically when the temperature in your home drops, you may find yourself shivering. Your furnace, when it’s operating properly, should turn on when it’s prompted by the thermostat. A furnace that isn’t turning on automatically could be a result of numerous factors. 

The first thing to check in the scenario is the thermostat. You may simply have the thermostat set to a low temperature. By raising the temperature on your thermostat, you may be able to easily get your furnace to switch on. Or, if your thermostat is set on the cool setting, or turned off altogether, your furnace won’t get the signal to heat your home. 

If your circuit breaker is turned off, it may be causing your furnace troubles. Check your breaker box and try flipping the furnace switch. This may get your furnace to kick in if the trouble was stemming from the circuit breaker.

The Furnace Keeps Turning On and Off

When a furnace keeps turning on and off at a frequent rate it’s called short cycling. This issue can be frustrating and will cause ongoing problems, including higher utility bills and a shorter furnace lifespan. 

A few issues could be causing your furnace to short cycle. For one, your thermostat may be malfunctioning. In this case, you’ll need an HVAC specialist to check it out and complete repairs as necessary. A clogged filter could also be triggering short cycling. This can be easily resolved with a new, clean filter. 

Note that when the temperature outside is below freezing, short cycling could be normal. Your furnace will struggle to maintain a comfortable temperature in your home when the weather is extremely cold. 

The Furnace is Making Strange Noises

If your furnace is making unusual noises, such as banging, squealing, screeching, humming, or thumping, there could be a problem inside of your furnace. This could be an indicator of a major issue, so you should shut off the furnace immediately to avoid further damage. Contact your furnace repair experts to complete an inspection and return your furnace to working order.
