8 Things That Should Be Part of Your AC Maintenance Check

Getting regular maintenance checks is an important part of caring for your air conditioning system. This helps you extend the lifespan of your machine and helps you avoid air conditioning repair costs.

It’s considered ideal to have your AC checked at least twice a year, around Spring and Fall. Just make sure that you don’t miss out on these essential marks whenever you get your AC maintenance check.

1. Thorough Inspection of Electrical Components

The proper function of your AC unit is highly dependent on the condition of its electrical components. This is not just a matter of efficiency but also safety. You don’t want any electrical failure to potentially increase your electrical bills, ruin your unit, and end up causing an electrical short that can hurt someone.

2. Check and Replacement of Air Filters

If your air filters are dirty and clogged, your air conditioning and heat won’t circulate efficiently. This will not just reduce the efficiency of your AC unit but also increase the energy bill.

So, make sure the filters get checked and replaced accordingly. This will do wonders for the unit’s airflow and prevent further issues.

3. Thermostat Calibration

It’s always a good idea to have the thermostat calibrated during your regular checks. This is because the thermostat naturally becomes less accurate over time.

While significantly inaccurate thermostats can also indicate a deeper issue that needs air conditioning repair, you can also expect normal wear and tear to cause reading accuracy shifts. This is why it’s simply best to get it calibrated.

4. Cleaning of Condenser Coils

The coil is responsible for transferring the heat from your AC unit to the outside. That’s why it’s essential to clean the coil regularly. If you don’t clean it, it won’t be able to serve its function properly and will eventually result in a warmer unit that is less capable of cooling the space it’s installed in.

5. Refrigerant Check

Refrigerant leaks can be not only a bad thing for your HVAC system but also for the environment. Check for any leaks and make sure that refrigerant levels are optimal so that your air conditioner can more effectively cool the space. This also helps prolong the life of your unit.

6. Assessing Drain Lines

Professionals should also check the drain lines when performing a maintenance check on your air conditioner. This will help them determine if there are any issues with drainage, standing water, and the like.

The drain lines are responsible for keeping moisture levels at a minimum to prevent mold growth and water damage.

7. Lubricating Motors

A professional will also make sure to lubricate the motors in your air conditioning unit. This will prevent any corrosion and build-up of dust and debris due to the friction in the bearings. It also keeps noise levels at a minimum. Make sure your HVAC technician checks the motors and oils them as needed.

8. Looking Over Evaporator

The evaporator will have to be checked during your regular maintenance check as well. The evaporator is also essential for your air conditioning unit’s ability to transfer heat properly and produce cool air. This will usually be checked hand-in-hand with the condenser coils.


It’s better not to wait for any major issues before getting your AC checked. Keep these in mind whenever you have maintenance done so that you can truly make the most of your system.
