Your technician will check the circuits, safety controls, drain line, condensate pump and also all caps and valves. Electrical components will be inspected for signs of wear or damage and replaced to prevent sparks or failure. You'll check that your outdoor unit is level for optimal performance. The HVAC service plan includes a comprehensive verification performed by a licensed service technician.
He or she will inspect your system for signs of leaks, problems with electrical connections and wiring, and efficient operation of the thermostat. An experienced HVAC technician will know how to replace your oven filter much more often than once a year. Ideally, this step would occur in a 2-month cycle. Your system will remain clean and free from any consequences of airflow restriction.
Heating and cooling systems require minimal air flow during each cycle. A dirty filter is the biggest offender in causing airflow problems. However, if you use a heat pump system all year round, you'll need to schedule an HVAC service for it every 6 months. You can always check to see if your local HVAC repair company offers annual HVAC maintenance contracts at affordable prices.
Some factors integral to an HVAC service will be checked, such as the efficiency of the thermostat operation, possible leaks, and problems with electrical connections and wiring.
