The Importance of End of The Season AC Maintenance

As summer winds down and fall approaches, it’s time to take a look at your AC unit and close it down for the upcoming winter months. Before you know it, you’ll be opening the windows wide and taking advantage of all that natural cool air! End of season maintenance is a crucial aspect of your HVAC system because it ensures your equipment will be ready to cool your home next summer. Let’s take a look at some key benefits of air conditioning maintenance programs:

Repair Savings

If you liken your AC system to your car, you’ll see that it needs the same regular TLC in order to keep running efficiently. Failure to maintain your system means it will be more susceptible to breaking down. When your unit breaks down, it’s costly to repair — not just in parts but in labor as well. According to, end of season maintenance can include:

  • Clean evaporator coil and condenser coil
  • Remove debris
  • Change filter
  • Unclog condensate drains
  • Comb aluminum fins on evaporator and condenser coils
  • Remove window units and cover outdoor units
  • Check for correct amount of refrigerant
  • Test for refrigerant leaks
  • Capture, legally, any refrigerant that must be evacuated from the system
  • Check for and seal duct leakage in central systems
  • Measure airflow through the evaporator coil
  • Verify the correct electric control sequence and ensure the heating and cooling system cannot operate simultaneously
  • Inspect electric terminals, and clean and tighten connections
  • Lubricate motors and check belts for tightness and wear
  • Check the accuracy of thermostat

All of these things will reveal any potential problems to your technician so that they can be addressed sooner rather than later when they can get out of control and even more costly. Even failing to cover your outdoor unit now means that same debris that was there in fall will be there in spring, so you’ll have to do some clean-up eventually.


Come spring, you want your AC unit to start right up and work the way it should. Shutting the unit down in fall without giving it a once-over may allow potential problems to fester over the year. Dust, dirt and debris can slow down the performance of your unit so it has to work harder to achieve the same level of comfort. Not only does this prevent you from being as comfortable as possible, it also increases your energy bills. A big part of keeping up with efficiency is ensuring you change your filter regularly. Clogged, dirty filters block normal airflow; replacing those filters with new ones according to manufacturer instructions means you can cut your energy consumption by up to 15%.

Air Quality

In the same vein, performing end of season maintenance goes a long way toward ensuring your indoor air is clean and safe to breathe for all occupants when it’s time to use it again. This way, you’re preventing allergens that can irritate asthma and allergies, or even more serious health problems.
