Your furnace works hard during the coldest months of the year, and like any appliance, it can encounter a range of problems. Routine inspections coupled with timely maintenance and repair services decrease the chances of heating system issues to keep your home comfortable. Here, learn about the most common issues affecting furnaces to keep yours functional and efficient.

4 Furnace Problems Homeowners Frequently Deal With

1. Clogged Air Filter

As dust accumulates in your furnace’s air filter, it restricts airflow. The heating system works harder as a result, increasing energy consumption and decreasing household comfort. Without routine filter cleanings and replacements, the system could even break down. Check your air filter about once a month, especially if you have pets, to avoid airflow problems.

2. Thermostat Issues

A malfunctioning thermostat may require something as simple as a battery change. There could also be a programming defect, a wiring issue, or dirt buildup that impedes function. Change the batteries and check the settings on your thermostat. If you still experience problems, contact your local HVAC contractor.

3. Cracked Heat Exchanger

Years of use or overheating issues related to dirty air filters and small ductwork can eventually crack your heat system’s exchanger component. Since the part prevents dangerous gases such as carbon monoxide from entering your residence, a crack presents a serious safety issue. Shut the heating system down any time your carbon monoxide detector goes off and schedule emergency repairs. HVAC contractors also check the heat exchanger during annual inspections.

4. Strange Noises

While most heating systems make some noise, loud or unusual sounds should never be ignored. Screeching noises typically indicate issues with the blower wheel or motor, while rattling sounds can signal loose ductwork. Squealing noises usually point to a slipping or loose blower belt or a problem with the blower motor itself. If your heating system makes an unusual noise, turn it off and call your HVAC contractor to diagnose and solve the problem.
