Maintenance

Business owners and managers may think they are saving money by only servicing their commercial heating, ventilation, and air conditioning (HVAC) units when there is a problem. The reality is that such a strategy is likely to end up costing businesses and homes more money on HVAC repairs in the long run than having their HVAC units serviced on a regular basis.The ENERGY STAR® program from the U.S. Environmental Protection Agency recommends having an HVAC contractor perform semiannual preseason maintenance checkups. It’s wise to schedule a contractor to check the cooling system in the spring and the heating system in the fall.

At both the spring and fall maintenance checkups, the contractor should check thermostat settings to ensure that the cooling and heating systems keep employees and customers comfortable during business hours and save energy when the building is unoccupied.
