As winter keeps the chill going, it’s more important than ever to ensure your heating works properly. When the furnace or vents of your property suffer damage or a failure, you need a quick and effective response. Getting the right kind of St. Louis furnace repair can help ensure your family is comfortable and safe when it’s cold out. To help get a quick repair, it can be beneficial to know what the problem is. By accurately describing the issue over the phone, your furnace repair technician can be better equipped to handle the job as soon as they arrive.

Common Sources of Furnace Trouble

Furnaces and HVAC units can be complex and tricky. But you don’t need an advanced degree in furnace repair to know when something’s wrong. By taking a second to examine the situation, you could identify the source of the problem to help expedite the repairs.

Dirty Ducts

If your heating isn’t working efficiently, it could be caused by dirty ducts. As dust and debris build up in your ducts, they create blockages. These blocks make it harder for your furnace to move warm air into your home. As such, your heater will likely have to work twice as hard to keep your temperature controlled. If you notice that your heater is always running without your property getting much warmer, it may be time to get your ducts cleaned out. 

Dirty Air Filter

While it’s not as impactful as a clogged duct, a dirty air filter can also cause your furnace to run less efficiently. Changing out your furnace’s air filter is a quick and relatively easy job that most homeowners can do on their own. However, if you aren’t sure what kind of filter you need, it may still be a good idea to call your furnace repair technician. They can help ensure you’re getting the right kind of filter for your furnace and heating needs. 

Broken Starting Mechanism

If you have an older furnace in your home, you may be able to see the pilot light inside. This is the starting mechanism that was used in most furnaces until recent electrical ignitions became popular. Regardless of what kind of starter you have, it’s a common issue for it to malfunction or break. If your heater doesn’t kick on despite turning up the heat, there could be an issue with your starting mechanism. While you may be able to relight the pilot on an older unit, it’s usually best to call a professional. They’ll be able to ensure your furnace is started safely and can provide other necessary repairs if the starting mechanism is broken.

Damaged Blower Components

The blower mechanism of your furnace is what helps it push the hot air it produces through your home. If your furnace is on but you can’t feel any warm air being pushed out, then there could be something wrong with this mechanism. The blower bearings, belt, or capacitor may be damaged and need repairs or replacement. It’s important to note that running your heater with a damaged blower component could lead to further damage. So, if your furnace isn’t producing warm air, turn it off until you can get a repair technician on site.

Damaged Heat Exchanger

The heat exchanger in your furnace is where all the warmth comes from. But over time, this coil of heated tubes can sustain natural wear and tear. Routine furnace repair can often help ensure your heat exchanger lasts for a long time. If it does break down, you’ll often be facing a fairly costly replacement. However, replacing your heat exchanger is still more cost-effective than replacing the entire furnace, so long as the other components are still functional. 

Malfunctioning Limit Switch

The limit switch is the part of your furnace that reacts to heat levels to turn the furnace off. It can switch off your furnace when your home reaches the desired temperature. It also serves a valuable safety function of preventing fires if your furnace starts overheating. If your furnace seems to be running continuously despite the heat setting, it may be a sign that your limit switch is malfunctioning and in need of repair. 

Malfunctioning Thermostat

In some cases, the issue with your heating may not be the fault of your furnace at all. The thermostat in your home detects the temperature and uses that to tell the heater when it’s time to turn on. If you notice that your heater doesn’t turn on until it’s extremely cold, it could be that your thermostat is reading the wrong temperature. Fixing your thermostat can often help rectify the issue without the need for direct furnace repair. 

Electrical Issues

It’s not entirely uncommon for a furnace to trip a circuit breaker when it’s running often enough. However, if your furnace continues to cause power issues, there could be a major electrical problem in your home. Your furnace repair technician can help determine if the issue is with the furnace or with your circuit breaker. In the event of the latter, they can help you find an electrician who can sort out the problem.
