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.
Including but not limited to the following:
- Inspect equipment for unsafe conditions: cracked heat exchangers, heat transfer surfaces, and visually check for refrigerant or lubricant leaks.
- Replace or clean customer-provided air filter for covered equipment.
- Replace or clean customer-provided pad (humidifier ONLY) for covered equipment.
- Visually check the covered equipment for deteriorated wiring and wiring connections.
- Visually inspect electrical controls (contactors, relays, motor starters, phase monitors and timers) for deterioration and proper operation.
- Clean condensate drains and condensate traps if any on covered equipment.
- Clean indoor and outdoor heat transfer services.
- Lubricate indoor and outdoor heat transfer services.
- For refrigerant bearing equipment, verify proper refrigerant charge.
- Measure and record equipment operating voltage and current, and verify it is within manufacturer’s specified range.
- Where applicable, inspect and/or adjust burners for proper operation and efficiency.
- Where applicable, check fan belts and adjust belt tension on covered equipment. Calibrate and adjust economizer or outdoor air dampers for proper operation if applicable.
- Verify operation of safety controls for covered equipment where applicable: high limit, high and/or low refrigerant pressure switch, compressor oil failure control
- Where applicable, verify proper operation of the electric heat elements, reversing valve operation (heat pump systems) and defrost timers (heat pump systems) for covered equipment.
- Provide written recommendations for corrective actions, if any.
