Five Common Furnace Problems

Most people only think of their furnace only when it does not work when they need it to. However, many people would pay more attention to their furnace if they knew how many things can go wrong with it. Below are some common furnace problems:

Common Furnace Problems

1. Clogged Air Filter

This is one of the most common problems with the furnace, but also the one that is most easily fixed. A clogged air filter can result in high heating bills and can make temperatures in your home less comfortable. A clogged air filter is also one of the most common reasons furnaces break down. Taking a few moments to check and change your filter on a regular basis can save you a lot of trouble.

2. Malfunctioning Thermostat

Thermostats are responsible for ensuring that your furnace turns on and off when the air reaches a certain temperature. If the temperature in your home is not staying as comfortable as you'd like, a faulty thermostat may be the issue.

3. Pilot Light Out

If your furnace does not come on at all, the problem may be as simple as a pilot light that has gone out. If the pilot light is the issue, you can check the light and relight it yourself. However, if the pilot light keeps going out, you may need to call a professional to inspect the furnace.

4. Cracked Heat Exchanger

A cracked heat exchanger is one of the more serious things that can go wrong with your furnace because potentially deadly carbon monoxide is produced. Heat exchangers are commonly checked during tune-ups of your HVAC system.

5. Blower and Belt Problems

If you are having problems with airflow, the problem could be either with the blower belt in your furnace. The problem could simply be a bad belt. However, if the furnace is making a high-pitched noise, the problem could be more serious and may be a problem with the blower. Avoiding problems with the blower is easy with a yearly tune-up of your furnace.
