What a Technician Looks for During an AC Inspection

If you’re on the prowl for a new HVAC technician to inspect your AC, it might be beneficial to know exactly what the technician does! Specialists who work on air conditioners usually use a narrowed-down checklist that can help them identify if there are any problems with the function of your AC. While we might not be able to give you that exact checklist, we can tell you about a few items that are usually on those lists, which end up being some of the more common problems for AC systems.

AC inspections are paramount to the health and lifespan of your air conditioner. We’re not saying that you should perform your own AC inspections after reading this blog post, but maybe this information could help you be more aware of what technicians are looking for when they open up your machine. Regardless of whether or not you think there’s a problem with your AC, it’s never a bad idea to schedule HVAC maintenance in Shreveport, LA with one of our technicians.

So let’s get into it. What does a technician look for when they perform an AC inspection?

Common Places to Look

Not every technician has the exact same process for checking up on an AC system. Some prefer a different order, checking on different items, or have a completely different routine. However, most technicians probably look at the following items when inspecting an air conditioner.


Filters should be changed every 1 to 3 months. This can be more frequent if the AC is in heavy use or if the summer is particularly hot. Filters are not really supposed to clean your air (although they do that on accident), filters are mainly to keep contaminants and debris from entering into the air conditioner. Dirt and debris can harm the compressor, collect on the coils, and lead to a breakdown of your AC system. So, it’s not uncommon for a specialist to look at your filters before anything else- because a dirty filter could signal that there are other problems.


It’s common for an HVAC technician to check the efficiency of your cooling system. He might ask about your utility bills or the quality of cooling that comes from the system. With this information, sometimes it can be clear before they’ve even opened the machine up that there is a significant problem. Age, cooling, energy use, and other surface information can make it pretty clear when your AC is not in good shape.


Many problems with air conditioners are because of poor initial installation. An HVAC technician is very well aware of this and might check the size and installation parameters before even opening your system up. If your AC was installed haphazardly, or in the wrong size, this could cause several different problems and shorten the lifespan of your system by quite a lot.

We could go on for a while about things an HVAC technician will check on a routine inspection- but these are some major ones. If you’ve got a noticeable problem with any of these, you can bet that your air conditioner technician will notice it right away.
