Yes. It’s recommended that your HVAC unit undergoes regular maintenance so that it keeps working at full capacity. Maintenance checks should happen at least once a year.
But you might need more frequent check-ups. It all depends on the type of your business and the work rate of your cooling system. An AC system used in a residential environment for cooling only may only require maintenance once a year. But for HVAC units that both heat and cool in shops and offices, two check-ups may be necessary. And if there are a lot of air pollutants in the air, for example on a factory floor, it may even be that three visits are needed.
Without frequent check-ups, your air conditioning system‘s filters, coils and fans will get clogged with dirt, dust and grime. After a long period of neglect, your AC unit will start to fail, use more energy for the same cooling effect, and may even become a fire hazard.
