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.
- 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.
- 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.
- Lubricate all moving parts to reduce friction in motors and lower the amount of electricity used.
- 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.
- 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.
- 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.
- Check your central AC’s refrigerant level and adjust if necessary.
- Clean and adjust blower components to provide proper system airflow and improve overall comfort. Airflow problems can reduce efficiency by up to 15%!
- 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.
