How to tell if a rooftop air conditioning unit needs maintenance?

A rooftop air conditioning unit is an air conditioning device installed on the roof that absorbs outside air and processes it to provide a comfortable indoor air environment. Rooftop air conditioning units usually consist of air handlers, fans, humidifiers, filters and other components, which can be combined as needed to meet different air treatment needs. Rooftop air conditioning units have the advantages of small space occupation, easy installation, and simple maintenance, so they have been widely used in commercial buildings, office buildings, hospitals, hotels and other places.

To determine whether a rooftop air conditioning unit requires maintenance, you can consider the following aspects:

Runtime: If your air conditioning unit has been running for a long time, it may need maintenance.

Noise: If your air conditioning unit is making unusual noises, then it may need maintenance.

Cooling: If your air conditioning unit is not cooling effectively, it may need maintenance.

Air Quality: If the air quality of your air conditioning unit is poor, then it may need maintenance.
