Air Conditioner Inspection Checklist For Homeowners

It’s not quite the same as the inspection required yearly for your vehicle, but it is just as important to perform an inspection on your home’s air conditioning system at least once a year. Failure to do so could lead to malfunctions and system failures that could result in costly repairs or worse, a complete replacement. While lots of components of the annual inspection should be left to a trained professional, there’s a whole separate checklist homeowners can perform and tackle on their own. Here’s what you can do to get started:


Check on your cooling system’s filter once a month, at minimum. Look for traces of dust, dirt or other debris that could cause the filter to clog and clean or replace it upon detection. You don’t want that stuff flowing through the vents and into the air for you and your family members to breathe in, and a clogged or dirty filter can cause a wide variety of malfunctions system-wide.


Take a look at all registers and make sure the louvres are open. We also recommend keeping furniture, rugs and any other larger household items away from vents and registers to allow adequate airflow to circulate through the system. 

The same goes for the outdoor portion of your cooling equipment. Make sure there is at least two feet of space around the condenser to allow air to flow freely.


Make sure your thermostat is set to “cool” and that it’s working properly. Check the temperature and daily/weekly settings to align with your summer schedule in order for your system to operate at peak efficiency. 

If you notice issues with your thermostat, have them addressed right away as this is one of the most critical components of any home hvac system.
