3 HVAC Components That Can Get Overlooked

Posted on

Your home's HVAC system plays an essential role in keeping your family comfortable each day. Without a functional HVAC system, it would be impossible to heat or cool your home to the correct temperature.

Most homeowners know that investing in regular inspections for the furnace and air conditioner are required to keep an HVAC system running properly, but may overlook some smaller components that can have a big impact on HVAC performance.

Air Return

The air return(s) in your home serve as the starting point for HVAC function. The air that is heated or cooled by your HVAC appliances is supplied through the air return. Once the furnace or air conditioner engages, air is sucked into the air return and passed through a filter on its way to be heated or cooled.

Once this air reaches the proper temperature, it is distributed throughout your home via your air ducts. If you allow your air return to become dusty, your filters will clog up much faster. Take the time to dust and clean your air return on a regular basis to maximize the efficiency of your HVAC system.


When temperatures begin to fluctuate within your home, you initial instinct may be to assume something has gone wrong with your furnace or air conditioner. Many HVAC problems can be addressed by looking at your thermostat instead.

Since most thermostats are located on the wall, these devices can easily be bumped by family members. Ensure that the temperature settings on your thermostat are correct, and take the time to change out the batteries in your thermostat regularly.

Dead thermostat batteries will cause disruptions in HVAC function that may mistakenly be attributed to a broken furnace or air conditioner.

Outdoor Fan

Your HVAC system likely has an outdoor unit that houses the fan. This unit is overlooked by homeowners when it comes to routine maintenance because it isn't constantly visible. You need to take the time to clear away any branches, shrubs, or debris that might be blocking your outdoor fan.

Build a small, breathable enclosure around the outdoor fan to prevent pets from urinating on or damaging the unit in any way. Caring for your outdoor fan will help your HVAC system run more efficiently and prevent the need for costly repairs in the future.

Don't overlook any of the components within your HVAC system when it comes to regular care. Cleaning your air return, monitoring your thermostat, and keeping your outdoor unit clear will help ensure your home stays a comfortable temperature without straining your HVAC system.
