What Actually Happens During a Professional AC Tune-Up?


If you’ve followed our blog at all, then you know we talk about maintenance a lot. This is because it’s a very important service! It allows our technicians to fully inspect, clean, and adjust the components that need it, within your air conditioner. This allows the system to work as efficiently as possible, for as long as possible.

In fact, and air conditioner that’s properly maintained each year (or biannually, in the case of a heat pump system) can be expected to have a useful service life of 10-15 years, while a system that goes without maintenance may last half of that.

But what actually happens during maintenance? We want you to trust that this is best for your system, so read on as we uncover some of the steps we take to highlight the importance of routine tune-ups. Also, ask about our Worry-Free Advantage Program! This is a monthly membership we provide that includes a number of benefits, including thorough maintenance.

Read on to learn more about what a maintenance tune-up entails, and please don’t hesitate to reach out with any questions you might have about our program or any services we offer.

It is important for us to mention here that just about all internal AC maintenance tasks should be completed by trained and experienced professionals. There is, however, one small maintenance task that you can and should be doing on your own—changing the air filter!

The air filter that comes standard with your HVAC systems is in place to protect those HVAC systems from dust, dirt, and other debris that could make its way in and damage sensitive components. Depending on the type of filter you have, and the level of contaminants in your home, you should replace or clean this air filter every 1-3 months.

Professional maintenance should be done at least annually, so you can see why your air filter should be checked more often than every maintenance session!

Now, with that aside, onto what our technicians actually do during your maintenance session. This is a brief overview, but please feel free to reach out to us if you would like a more detailed explanation!

  • We check the system’s evaporator and condenser coils to make sure that they are clean, unobstructed, and can effectively absorb and release heat.
  • We check on your refrigerant levels to ensure they didn’t drop. Refrigerant works in a closed-loop system, so the only time a system will lose refrigerant is if there is a leak that needs to be located and repaired.
  • We check on all the electric connections, tightening them where needed.
  • We clean the condensate pan and drain, in addition to the fan and compressor motors.
  • We lubricate the motor bearings. Without this, friction can cause the motors to eventually overheat.
  • We check that your thermostat is calibrated correctly and that it’s accurately reading the temperature of the room.

As we noted above, this is a rather brief overview. We’re happy to give you more details, just ask any member of our team!
