HVAC maintenance and repairs are common investments for homeowners. According to The Bureau of Labor Statistics, the HVAC industry is expected to see a 15% increase in jobs by 2026. If you think you have a furnace problem, here are seven of the most common furnace repairs.

1. Dirty Ducts

Proper airflow helps your HVAC system do its job so you don't want to let dirt and dust build up in your ducts. Dirty ducts can eventually cause your furnace to stop blowing warm air or moving air at all, so get your ducts cleaned every few years.

2. Dirty Air Filters

You should change your air filter about once every three months to prevent airflow issues and maintain good indoor air quality. If you have several pets or a lot of people in your household, you might want to change your air filters more often.

3. Bad Thermostat

A bad thermostat can cause your furnace to cycle on and off when it shouldn't, so make sure you have your thermostat checked when you have your furnace serviced.

4. Broken Blower

Blower problems are some of the most common furnace repairs. If your blower isn't working properly, there won't be any airflow to move warm air through the ducts and into various parts of your home.

5. Starter or Pilot Light Problem

If you have a problem with your starter or pilot light (for gas furnaces), your furnace might not even kick on. A furnace that doesn't turn on is a good sign that you've got a starter or pilot light problem.

6. Strange Noises

Strange noises coming from your furnace can be caused by bad belts, loose parts, or a broken blower motor. If you hear strange noises coming from your furnace, it's time for furnace repairs.

7. Limit Switch Problems

Limit switch problems can lead to your blower running constantly instead of cycling off. If your furnace doesn't stop running when it should, you might have a broken limit switch.

Diagnosing furnace problems on your own is tough, and trying to fix furnace problems without experience can be dangerous. If your furnace isn't quite working right or you haven't had maintenance in a while, call MD's Heating and Air Services LLC to schedule service today.
