If your window-mounted air conditioners were covered with plastic during the refacing process of the apartment building, there are a few things you should check and address to ensure their proper functioning and longevity:
Inspect for damage: Carefully examine the air conditioners for any visible damage or deformation caused by the plastic covering. Look for dents, bent fins, or any signs of stress on the unit.
Clean the air filters: During construction, dust and debris might have accumulated on the air conditioner's filters. Remove and clean the filters according to the manufacturer's instructions. Clean filters allow for better airflow and improve the unit's efficiency.
Check the condenser coils: The condenser coils located at the back of the air conditioner might have gathered dirt, dust, or debris during the construction process. Clean the coils gently with a soft brush or a vacuum cleaner to maintain good heat transfer and efficiency.
Inspect the seal around the unit: Ensure that the plastic covering did not damage the seal between the air conditioner and the window frame. A proper seal is essential to prevent hot air from entering the room and to ensure the unit operates efficiently.
Test the air conditioner: Turn on the air conditioner and check if it is cooling effectively. Listen for any unusual noises and monitor the temperature to ensure it is functioning correctly.
Check for proper drainage: If your air conditioner has a drainage system, make sure it is not clogged or blocked. Proper drainage prevents water from leaking inside your apartment and causing damage.
Schedule professional maintenance: If you notice any issues or you're unsure about the condition of your air conditioner after the construction, it's a good idea to have a professional HVAC technician inspect and service the units. They can perform a thorough check, clean the internal components, and address any potential problems.
Consider a follow-up cleaning: Depending on the length of time the air conditioners were covered and the extent of construction debris, you might want to perform a more comprehensive cleaning or consider hiring professionals to do so.
By taking these steps and ensuring your window-mounted air conditioners are in good condition, you can help prolong their lifespan and maintain efficient cooling in your apartment.
