An HVAC diagnostic test should be part of the regular annual maintenance performed by certified technicians. This test identifies potential problems so you can avoid unwanted costs, and it can help keep your heating and cooling system running at optimum efficiency.

A typical HVAC diagnostic test should include:

  • Check thermostat settings to ensure your HVAC system keeps you comfortable and also saves you on energy costs while you’re away from home.
  • Inspect all electrical connections and measure voltage and current on electrical components. Malfunctioning or damaged electrical connections are hazardous and they can reduce the life of major HVAC system components.
  • Lubricate all moving parts.Without lubrication, friction in the motor can increase the amount of electricity your HVAC system uses.
  • Inspect the air conditioner, furnace and heat pump condensate drain. Plugged condensate drains can lead to water damage and they affect humidity levels in your home.
  • Inspect HVAC system controls to ensure proper and safe operation.
  • Test the starting cycle of your HVAC equipment to make the system starts, runs, and shuts off properly.

During the spring, your HVAC technician will also clean and modify the blower components, check the refrigerant levels, and clean evaporator and condenser coils. This cleaning improves the energy efficiency of your cooling system and prolongs its service life.

In the fall, your HVAC technician will check all furnace fuel connections, and also test burner combustion, gas pressure, and inspect the heat exchanger. If these components are not inspected and cleaned, your furnace may pose a fire hazard and improper operation can lead to health problems.

Because HVAC contractors get busy in the summer and winter months, it’s best to schedule HVAC diagnostic tests in the spring and fall.
