How to Do Proper Maintenance and Cleaning of Your Window Air Conditioning Unit

Updated: Sep 1, 2022

Summer is in full swing, and that means blistering hot temperatures! Like most people, you're probably using your window air conditioning unit to keep cool. But did you know that it's essential to do regular air conditioning maintenance and cleaning on your AC unit?

This blog post will teach you how experts can clean and maintain your window AC unit properly. Follow these tips, and you'll be able to keep cool all summer long!

1. Cleaning the Filters

The AC filters are critical because they ensure that the air inside your room is clean. When the filters are full of dirt and dust, it can cause the AC unit to work harder and use more energy.

Here are the steps used by all service heating and air companies to clean the filters:

a. Remove the front panel of the AC unit to access the filter.

b. Use a vacuum cleaner with a soft brush attachment to remove any dirt and dust from the filter.

c. Rinse the filter with water to remove any remaining dirt and dust.

d. Allow the filter to dry completely before putting it back in the AC unit.

e. Replace the front panel of the AC unit.

If you have a reusable filter, you should clean it at least once a month. If you have a disposable filter, you should replace it every three months.

2. Checking the Refrigerant Levels

The ideal pressure for your system will be printed on a sticker or plate somewhere on the A/C unit. Typically, this is between 80 and 120 PSI (pounds per square inch).

Be sure to check for leaks in the system before you add more refrigerant.

If your A/C unit is low on refrigerant, it won't be able to cool your home correctly. Experts use tools and devices like refrigerant gauges and leak detectors to check the levels and find any leaks.

3. Vacuuming the Interior and Exteriors

Dust, dirt, and other debris can accumulate on both the interior and exterior of your window air conditioner unit. Here's how calling in a professional can help keep your unit clean and running smoothly:

-They will use vacuum hoses with special attachments to reach all areas of your unit, including the coils and fan blades.

-They will also remove any debris that has accumulated on the exterior of your unit.

-It will help ensure that your window air conditioner unit can run smoothly and efficiently.

4. Checking for Obstructions in the Airflow

The airflow through the unit is essential for it to function correctly. If there are any obstructions in the way, it could cause the unit to overheat and break down.

To check for obstructions, HVAC heating and air conditioning service technicians will:

Remove the unit's front grille and check for any blockages in the air ducts.

-Inspect the evaporator coils and make sure they are clean and free of debris.

-Check the condenser coils and make sure they are clear of dirt and dust.

-Make sure nothing is blocking the airflow around the unit.

5) Check the Thermostat

The thermostat tells the air conditioner when to turn on and off. If it's not working correctly, the air conditioner will run all the time or not at all. All service heating and cooling experts will check if the thermostat is set to “cool” and correct the temperature setting.
