Inevitably your air handler will eventually need something repaired - whether it be your blower, fuses, coil, motors, fan, economizer, etc. Although maintaining your equipment cuts down on repairs, it cannot prevent all problems from happening.
Common Air Handler Issues
Over the many years repairing air handlers we frequently run into these issues:
Obstructions - one of the most common issues we run into with an air handler is obstruction to airflow, causing the unit to work harder than needed to pull air through the unit. The most typical culprit is simply a clogged or dirty air filter - an easy fix. Either setup a regular maintenance schedule or possibly find a thermostat that notifies you that the air filters need to be replaced.
Evaporative Coil - dirt and grim buildup along the fins of the coil, creating a layer of insulation between the air and refrigerant. This makes it difficult for the refrigerant to absorb the heat, creating a rise in temperature. Furthermore, the refrigerant stays cold since it is not absorbing the heat and freezes condensate on the fins - which becomes a larger issue if not taken care of promptly.
Condensate Drain - first and foremost, check to see if the condensate drain is blocked. Condensation will drip from the coils into the pan, a drain will then carry the water in the wastewater system. This water will usually contain dirt, after time the dirt builds into a clogged drain. Water can then overflow causing water damage, increased humidity in the airflow, unpleasant smells and can be hazardous from the mold buildup.
Blower Motor Failure - unfortunately the a blower motor failure can have many different causes. Some of the most common seem to be from dirt buildup, bearing failure, electrical failure or insufficient voltage to the blower.
Some commercial air handler issues are not able to be fixed very easy and require specialty tools, knowledge or experience. Don't be afraid to call (801) 991-1120 to have our service tech come and repair it for you!
