A furnace.

Your furnace is one of the most important pieces of equipment in your home. It keeps you warm and cozy all winter long! But what do you do if it stops working? Don't worry, we're here to help. In this blog post, Medley Heating & Air Conditioning will share four common problems that can cause your furnace to malfunction. We will also provide tips on how to fix them. So whether your furnace is making strange noises or you just can't seem to get it to turn on, read on for help!

Dirty Filter

The most common cause of a malfunctioning furnace is dirty or clogged filters. This is why it's so important to change your filter every few months. A blocked filter restricts airflow, which can lead to decreased performance and even permanent damage to your system. To ensure optimal performance, you should check your filter every month and replace it whenever necessary.

Thermostat Issues

If your thermostat isn't working properly, it can disrupt the temperature inside your home. Check that the batteries are fresh and that the temperature setting on the thermostat is correct for the season. Also, make sure nothing is blocking the sensors in the thermostat from accurately reading the room’s temperature.

Pilot Light Problems

If your furnace won't turn on, it could be due to a malfunctioning pilot light. Check the pilot light to make sure it is burning blue and adjust it if needed. If you can't get the pilot light to stay lit, call in a professional HVAC technician for help.

Ignition System Issues

The ignition system includes the spark igniter and gas valve that work together to ignite the fuel within your furnace. Sometimes these parts become dirty or corroded, which can cause them to malfunction and keep your furnace from turning on properly. Have an experienced technician inspect this part of your system periodically to ensure optimal performance.

These are just some of the most common problems that can cause your furnace to malfunction.
