Understanding DIY or Professional HVAC Maintenance Tasks


Your home’s HVAC system needs regular maintenance to operate well for its lifespan. Much of that needs to be performed by a qualified professional. Heating and cooling systems have sensitive components that need expert handling for both your safety and the safety of the machinery. Here are some guidelines regarding tasks you can take care of and what jobs are best left to your technician.

Changing the Filter

You should change filters whenever they are dirty because grimy filters lead to problems such as stressed fan motors, dirty evaporator coils, dirty air ducts, and dust in the air you breathe. This is an easy task requiring little time and effort and most homeowners prefer to handle it without help.

If dirty filters have caused problems for the system, that is another story. Make sure you call your HVAC technician if your coils have frozen, if you suspect your ductwork is dirty, or if the fan motor keeps shutting off.


Seasonal HVAC maintenance visits usually include some cleaning tasks specific to the machinery. Your contractor can take care of cleaning the coils and cleaning interior parts that have gathered dust.

Some cleaning projects are DIY and will make your system run better as well as make any maintenance task easier. This includes keeping the area around the furnace and other interior HVAC components neatly swept and free of clutter. Outdoors, keep trees and bushes trimmed back from the compressor and don’t let brush or grass clippings build up nearby. The technician will appreciate clear access to the units. It also reduces the amount of debris being trapped inside.


It can be tempting to explore your HVAC equipment when something is malfunctioning. Clearing a clog in the drainage pan or tightening a bolt is fine, but avoid doing anything more than that. Call your technician to make repairs such as loose wiring, broken belts, or stalled fans. This is the safest and smartest way to handle these issues.
