HVAC Company in Gilmer, TX Discusses Problems With A Furnace That Require Repair

How To Fix Common Furnace Problems

A furnace consists of a number of components, such as the control system, gas valves, burners, heat exchangers, ducts, and blower. Each of these parts needs to be in its best condition so the entire furnace can effectively do its job, which is to provide heat in your property.

If any of the components develop an issue, you likely have to call an emergency furnace repair in Gilmer, TX before things get worse.

Here are some of the common problems that your furnace may experience:

Malfunctioning Thermostat

A thermostat is a device that controls your furnace. There are a few types of thermostats, such as digital, programmable, and mechanical ones.

Regardless of what system you have at home, it won’t work if there’s something wrong with the installation or the wiring. It also won’t function properly if the batteries are bad.

If the thermostat is not working properly, your furnace will either not turn on or won’t heat your home according to the temperature you set.

Dirty Filters

A furnace filter needs to stay clean so air can pass through seamlessly. If it’s clogged with dirt and dust, which can happen over time, it can impede airflow which will eventually result in other serious problems like damage to the limit switch.

Malfunctioning Pilot Light

A pilot light is a small flame that ignites the main burner. If it’s blown out, your furnace won’t work. The pilot light can malfunction due to factors like air drafts or wind. Other possible causes include dust on the spark electrode or a dirty flame sensor.

A pilot light may also struggle to stay lit if there’s a problem with the thermocouple, the device which opens or closes the gas line. 

Cracked Heat Exchanger

When the heat exchanger cracks, the deadly carbon monoxide can escape and mix with your indoor air. Your C02 detector may start alerting you once the heat exchanger gets damaged and let C02 escape. You might also experience symptoms of C02 poisoning like dizziness and dull headache.

Contact a professional furnace repair tech immediately in this case. A cracked heat exchanger needs to be replaced instead of repaired.

Short Cycling

Do you notice that your furnace seems to kick on frequently, often when it just finished a cycle? Then you may have a clogged filter, improper airflow, or are running your furnace too high or too low. Having a frequently cycling furnace will result in a higher power bill. 

There are many other problems that could happen with your furnace. Whatever the issue is, it’s always best to find a provider of furnace repair service near or in Gilmer, TX and let them deal with the problem.
