What does a typical HVAC maintenance check-up include? A number of things that can improve your efficiency and reduce your electricity costs. That’s why it’s so important to have your unit maintenanced regularly – at least once per year.

Here’s a look at what HVAC maintenance technicians can do to maintain a unit’s efficiency and cleanliness. This check-list is brought to you by our partners at Energy Star.

  1. Check thermostat settings to make sure the cooling and heating system keeps you comfortable while you’re at home, and saves you energy while you’re away.
  2. Tighten all electrical connections and measure voltage and current on the motors. Bad electrical connections can make your system unsafe and can reduce the life of its most important components.
  3. Lubricate all moving parts to reduce friction in motors and lower the amount of electricity used.
  4. Inspect the condensate drain in your central AC, furnace and/or heat pump (when in cooling mode). If a drain gets clogged, it can cause water damage in the home and affect the humidity indoors.
  5. Check the system’s controls to ensure proper and safe operation, and check the starting cycle of the equipment to make sure it starts, runs and shuts off properly.
  6. Clean the evaporator and condenser coils, since dirty coils reduce the system’s ability to cool your home quickly, resulting in a longer-running system, higher energy costs, and a shortened lifespan for the equipment.
  7. Check your central AC’s refrigerant level and adjust if necessary.
  8. Clean and adjust blower components to provide proper system airflow and improve overall comfort. Airflow problems can reduce efficiency by up to 15%!
  9. Check all gas or oil connections, gas pressure, burner combustion and the heat exchanger. If a connection is improperly operating, it can cause a fire hazard and health problems.

What can I do?

You’re probably wondering what you can do throughout the year to lengthen the life of your system and save money on heating and air costs. Energy Star offers this tip: Inspect, clean and change your air filters once a month in your central AC, furnace and/or heat pump. Your HVAC contractor can show you how to do this.
