The HVAC system consists of many parts that must function simultaneously for the system to work efficiently and properly. Every now and then, something becomes loose, worn out, or clogged and the entire system suffers as a result. Below are seven common issues with the HVAC system that may require professional service.
- Dirty filters
New homeowners often don’t realize the basic maintenance an HVAC system needs to function. One of the things every homeowner needs to do regularly is replace the air filters. Dirty air filters lower the efficiency of the HVAC unit, increasing wear and tear on the entire system. In a worst case scenario, dirty air filters can cause the furnace to overheat and shut down.
- Pilot or ignition problems
Problems with the ignition can be the result of a dirty pilot, flame sensor, or burner. A pilot outage, furnace lockout, delayed ignition, or short cycling can occur if there’s an issue with the ignition. In these cases, the hot surface ignitor or thermocouple may need to be replaced.
- Thermostat malfunctions
If the furnace isn’t reaching the temperature set on the thermostat, the issue may be in how it is set. The batteries may need to be regularly replaced to keep the thermostat running.
- Mechanical wear and tear
Wear and tear on the belts and bearings can lead to overheating, poor heating, and airflow issues. To prevent this, regularly check for worn or stretched belts and oil the bearings and motors. You may need to call Blue Apple for professional HVAC services to take care of this.
- Unusual furnace noises
If you hear whining or squealing coming from the motor, the bearings in an inducer motor or blower motor may be failing. In this case, you may need to replace the entire motor to avoid furnace failure. Other types of noises may be caused by issues with airflow or dirty burners.
- Blown fuses or tripped breakers
An overworked blower can cause the furnace to trip a circuit breaker. This may be due to a blockage in the airflow forcing the blower to compensate. Typically, replacing the air filter will address this issue.
- Dirty condenser or evaporator coils
It’s important to regularly clean the outdoor coil and indoor evaporator coil to keep dirt and debris from clogging up the system.
