Common Air Handler Service Questions

Yes, professionals can replace worn-out motors to restore efficient airflow.

When an evaporator coil becomes faulty, it can result in various problems within your HVAC system. These problems could include reduced cooling or heating capabilities due to ice formation and obstructed airflow, along with increased energy consumption and higher bills. Additionally, a damaged coil may lead to refrigerant leaks, which are environmentally harmful and decrease overall system efficiency.

Ultimately, if not addressed right away, a bad evaporator coil can even lead to a complete failure of your HVAC system. That’s why timely repair or replacement is crucial to maintaining your family’s comfort and your HVAC’s efficiency.

HVAC blower motors last 10 to 20 years, depending on how often the air handler runs. Regular maintenance can extend the life span of a furnace blower motor. Your HVAC maintenance cost will include annual cleaning and tune-ups by a technician. Decreased airflow, unusual smells and noises, or higher energy bills are all signs it’s time to replace a blower motor.

Your blower motor may make a loud sound if the bearings overheat or wear down as your system ages. You may also hear loud noises coming from your blower if it’s struggling to pull in air due to dirty or damaged ducts, closed or blocked vents, or a dirty air filter. Typically, this causes a loud whistling sound.

If your hot or cold air isn’t making it to your easy chair, this might mean that there is no blower to force it through the vent. Hearing a vibrating motor sound in the walls could also indicate that your furnace blower has gone bad. In any case, the only way to know for sure is by contacting an HVAC repair specialist near you.
