Room air conditioners, also called window units, work just like central air conditioners. They are smaller than central systems and are often more expensive to operate. Depending on its size, the room unit can cool only the room it is placed in, or it can also cool adjacent rooms.
The coils, compressor, and motor of the room air conditioner are sealed components, so any repairs should be left to a professional service technician. However, you can make minor repairs and regular maintenance will keep your unit running well. Here are some helpful tips:
1. Filter
Maintaining a clean air filter and replacing it regularly is essential. Clogged or clogged air systems have to work harder to create the necessary airflow and consequently use more energy. Some models are equipped with reusable filters, while others must be replaced. Refer to the product owner’s manual for filter specifications and usage instructions. Reusable filters that can be cleaned should be checked at least once a month and thoroughly cleaned as needed with warm water and a mild, unscented detergent. For filters that need to be replaced, it is generally recommended to replace the filter approximately every two months, depending on the air conditions inside and outside the home. If pollen and other airborne allergens are particularly bad, the filter will require more frequent maintenance.
2. Air conditioning coils
As the evaporator and condenser coils operate, dirt accumulates on them. Evaporator coils are prevented from being contaminated rapidly by a clean filter. With the passage of time, the evaporator coil will continue to collect dirt. Also beware that dirt reduces airflow and insulates the coil, reducing its ability to absorb heat. You can avoid this problem, check the evaporator coil every year and cleaning it as needed.
3. Clean the water container
The water container must be cleaned to prevent the growth of mold and mildew. They can produce a musty odor in the air. Use warm water, soap, or white vinegar to clean the inside base of the unit once it is disassembled.
4. Clean the tray and drain
Finish cleaning the inside of your window air conditioner by emptying the drip tray and draining the waste. To remove dirt or dirty water from the tray, grab a wet-dry vacuum cleaner (if you have one) or a damp cloth and pull out whatever has accumulated inside. Allow drying before reassembling.
In the end, check the drain to see if anything is blocking it. Wipe around the hole with a cloth and make sure there is a clear path for water to escape from the unit.
5. Reassemble and spray the cleaner on the unit
After you’ve cleaned and dried everything, it’s time to reassemble the window air conditioner and give it a final spray to prevent mold growth.
Grab a bottle of hydrogen peroxide and apply the solution to areas where air flows in and out. Wait for the peroxide to dry before using the device – and it’s done! Not only will you breathe cleaner and cooler air, but you will also extend the life of your air conditioner.
Final words
If regular maintenance isn’t enough or your unit is constantly having problems, you should seek the services of a commercial HVAC contractor. He would check the refrigerant levels and test for refrigerant leaks, measure the airflow through the evaporator coil, make sure all electrical components are working properly, and lubricate the motor and check the belts.
