It needs to be noted here that regular checkup of the commercial unit is the key to keep the units functioning at the peak of its efficiency but there could be symptoms that you cannot afford to miss and should call in an HVAC contractor on noticing those symptoms. For example, when the AC takes longer to cool or it is making strange sounds, there is excessive heating and even in case there are start-up failures you need to be careful. In fact, when all these symptoms are present the best option is to get in touch with an experienced HVAC contractor and sort out the problem soon.
However, some of the commercial air conditioner tasks that you will be able to perform by yourself are the following:
You can ensure that the air filters are clean. This is important because reduced airflow from a dirty filter makes the system work harder which in turn might decrease the overall lifespan of the unit.
It is also important to keep the overall unit clean because blocked airflow reduces the efficiency of the air conditioner. You can clean the fins around your outdoor condensing unit and any sort of weeds, bushes, or leaves close to the outdoor unit need to be removed.
It is recommended that sometimes visual inspection also should be done so that none of the vents outside your business are blocked. This is because blocked vents causes reduced airflow which in turn will cause extra strain on the commercial air conditioning unit.
It is always a good idea to keep a maintenance log so that you have a record as in when your commercial air conditioning unit is due for a professional inspection.
