A Guide to Furnace Repair: Common Issues and When to Call an HVAC Technician

A reliable furnace is essential to keep your home warm and comfortable when temperatures start to dip. Unfortunately, furnaces can experience problems that can disrupt your home's heating. Some common problems include a lack of heat, strange noises, and rising energy bills. When these issues arise, it's crucial to identify the source of the problem and decide whether to attempt the repair or call an HVAC technician for assistance. 

Lack of Heat

If your furnace is running but not heating your home, you'll need to troubleshoot the issue. Check your thermostat to ensure the temperature is set correctly and the batteries are fully charged. If this doesn't fix the issue, check your furnace's air filter to ensure it's clean. A clogged air filter can restrict airflow and cause your furnace to overheat. If your filter is clean and your furnace still isn't providing heat, it may be caused by a malfunctioning pilot light or a faulty thermostat.

Strange Noises

A noisy furnace is not only annoying but can indicate an underlying issue. If you hear rattling or banging sounds, it may indicate that there are loose or damaged components inside your furnace. Grinding noises could suggest issues with your furnace's motors or bearings. If you hear any unusual noises coming from your furnace, it's best to get them checked out by a licensed HVAC technician. Attempting to repair the issue yourself may lead to further damage.

High Energy Bills

If your furnace seems to be running correctly, but your energy bills seem to be creeping up, it may be time to check its efficiency. A furnace that's not functioning efficiently uses more energy, meaning higher costs for you. Check the age of your furnace, as an old unit may need replacing. Additionally, if your furnace has not been serviced regularly, it's time to have an HVAC technician come and inspect your unit.

Calling an HVAC Technician

While it's tempting to attempt DIY repairs on your furnace to save money, it's best to leave repairs and servicing to licensed HVAC technicians. They are trained and experienced and have the necessary tools and equipment to diagnose and fix issues. Additionally, having a professional service your furnace can help ensure its efficiency and longevity. It's a good idea to have your furnace serviced annually to catch any potential issues before they become major problems.
