Air Handler Services

Indoor unit containing blower and coil for air distribution.

Air handlers are indoor units containing the blower and evaporator coil that circulate conditioned air through ductwork. They pair with outdoor heat pumps or air conditioners. Unlike furnaces that generate heat, air handlers simply move and condition air. Many include heating elements for auxiliary heat. Air handlers are the indoor component of heat pump systems.

How Air Handlers Work

The air handler draws return air through filters, passes it over the evaporator coil for cooling (or heating in heat pump mode), and pushes conditioned air through supply ducts. The blower motor powers this circulation. Heating elements or hydronic coils may provide auxiliary heat.

Common Air Handler Issues We Repair

Blower motor failures
Evaporator coil leaks or freezing
Condensate drain clogs
Filter restriction from lack of maintenance
Heating element burnout

Air Handler Maintenance Tips

Change filters regularly
Keep condensate drain clear
Schedule professional coil cleaning
Inspect for duct connections
Check insulation condition
Listen for unusual blower sounds

Efficiency Information

Air handler efficiency depends on coil design, blower motor type, and airflow configuration. Variable-speed blowers significantly improve efficiency and comfort. Proper filter maintenance maintains rated efficiency.

Expected Lifespan

Air handlers typically last 15-20 years, similar to the heat pumps or AC units they pair with. Blower motors may need replacement during this time. Coil condition is critical to continued operation.

Bay Area Considerations

Air handlers are the indoor component of most heat pump installations in the Bay Area. Coastal humidity can affect coil conditions. Proper condensate drainage is important given variable humidity levels. Many homes have air handlers in attics, basements, or closets with different service access considerations.

Air Handler FAQ

How often should my air handler be serviced?

Annual maintenance is recommended, typically before the primary use season. Cooling equipment in spring, heating equipment in fall.

What is the typical lifespan of a air handler?

Air handlers typically last 15-20 years, similar to the heat pumps or AC units they pair with. Blower motors may need replacement during this time. Coil condition is critical to continued operation.

How do I know if my air handler needs repair?

Your air handler needs attention when: Weak airflow through vents. Unusual blower noise. Water around the unit.
