Every commercial space has an HVAC system in place to cool and heat the building when necessary. These HVAC systems account for a significant amount of a building’s energy bills. The systems need constant repair and maintenance to keep them running at peak performance. Therefore, most commercial buildings have HVAC repair maintenance schedules to keep the systems functioning well at all times. However, the HVAC equipment still develops issues. These problems affect the efficiency of an HVAC system, which in turn alters a commercial building’s internal temperature and energy consumption. A faulty HVAC system consumes a lot more energy to cool or heat a home. Essentially, a faulty system strains a lot to compensate for the lost function due to faulty parts. There are some common concerns of commercial HVAC systems that all commercial building owners should know. One is insufficient cooling and heating. Sometimes a commercial HVAC system might not cool or heat your building adequately, despite installing the right-size HVAC system. When this happens, you need to troubleshoot your HVAC system and find the causes for the inadequacy. Chances are, your commercial system has low refrigerant levels. The second common commercial HVAC concern is a thermostat malfunction. Check your HVAC system’s thermostat to ensure it has proper functioning batteries. Check its settings to ensure it is where you expect it to be. Open it up and clean all the dirt in the thermostat. Please put it back together and position it strategically in your commercial building. The final concern is an unusual noise. Sometimes a commercial HVAC system produces unusual noise due to component failure. When this happens, you need to call an HVAC professional to troubleshoot and fix the HVAC unit.
