The Benefits of an Air Conditioner Tune-Up
Regular air conditioning tune-ups and maintenance are important for many reasons:
- Better energy efficiency: Why make your AC work harder than it has to?
- Longer service life span: Delay buying a new air conditioner for as long as possible by taking care of the one you have with regular maintenance.
- Prevent emergency breakdowns: Getting a tune-up at the start of the season ensures your air conditioner will work properly all summer.
- Better air quality: If dirt is building up in your air conditioner, it ends up getting into your ducts and into the unit and its drains, where water may collect and back up, leading to mold and mildew growth. Poor air quality can also affect your allergies, especially in spring.

Frequently Asked Questions
What is HVAC maintenance?
HVAC maintenance, also known as servicing or tune-ups, refers to the process of assessing, cleaning, lubricating, repairing, and replacing components of your system as necessary to help it run as close to its original peak performance as possible despite normal wear and tear.
This includes minor things homeowners can do, as well as the annual professional maintenance recommended for most heating and cooling equipment.
How do I service my AC unit?
Servicing your AC comes in two parts. There are several things you can do regularly — usually on a monthly or seasonal basis, depending on your model — like cleaning the interior and exterior units of your AC and replacing or cleaning filters.
The more advanced parts of AC maintenance, which can involve opening your system to calibrate sensors, lubricating and replacing components, testing and correcting electrical connections, etc., should be left to a professional once a year — ideally in the spring, before the weather gets hot and technicians get busier.
That way you can be sure, heading into the hottest days, that your system will run at its best.
How long does AC maintenance take?
You should expect annual AC maintenance to take one or two hours, barring anything unusual. Since maintenance visits also include inspection for more serious problems, the visit could run a little long if a problem is found, even if it ultimately doesn’t warrant significant repairs.
The monthly maintenance you should do as a homeowner can likely be handled in a matter of minutes — you’ll want to change or clean your filter, depending on which kind you have, and clean off any obvious grime, debris, or mess on the system.
