Since the term Air Handler could be new to some people, we better explain what an Air Handler is before going into the details of its maintenance. Air Handling Unit (AHU) or Air Handler is a device which is used to regulate and circulate the air as part of an HVAC system. Apparently, an Air Handler consists of a metal box large in size which has a blower, filter chambers, heating and cooling elements, dampers and sound attenuators. This device called an Air Handler is usually connected to a ductwork system that spreads the air throughout the home and then returns the stale and non-conditioned air back to the Air Handler. Not only does an Air Handler regulates and circulates the air, it also cleanses it by using Air Filters. In order to have an effective circulation of cold air throughout the home, Air Handler system is necessary if you’re using a Heat Pump.

Just like the fan blades of Air Conditioner need to be cleaned for optimal performance, the fan blades of an Air Handler also want this cleaning. Blades accumulated with dust and debris have a hard time doing their job. Ease their discomfort by cleaning the blades carefully as to neither damage the blades nor hurt yourself. Use a soft brush preferably.

Check Moving Parts

The moving parts of the device need to be checked for corrosion, rust and repair needs.

Check Fan Shaft

Done with checking fan blades? Now check the bearing collar set screws on the shaft. Are they tight? If not screw them.

Do not forget dampers in your checklist. The dampers have to be clean for optimal performance and if dust and clogs are found on dampers, you know what to do; cleaning. Also, check that dampers linking and actuators are aligned and operational. The damper connections need lubrication too.

Check Coils, Valves and Refrigerant Lines

All the coils, valves, refrigerant lines, have to be cleaned and should be free from leaks and other damages

Check Condensation Pans

When checking your Air Handler, carefully check the Condensation Pan which sometimes gets rusted. It has to be rust-free in all conditions.  

Check Cooling Coils

Are your cooling coils drain and blown to remove moisture? If this is not the case, make the settings.

Check Freezestat
