What Does the Changing Season Mean For My HVAC System?

When the time comes to switch your HVAC system from “Heat” to “Cool” or the other way around, you need to make sure that your HVAC unit is prepared for the change of seasons. Follow the maintenance tips below to ensure that your HVAC system is running as efficiently as possible to guarantee optimum comfort.

#1 Change Air Filters

Changing the air filters is at the top of the list because it’s fairly simple to do, yet it goes a long way. The condition of your air filters can affect the efficiency of your HVAC system, not to mention the quality of indoor air. If the air filter is dusty and dirty, you are exposing yourself to allergens that can cause cold symptoms. Make it a habit to remember when you last replaced the air filter so that you’ll know when it needs to be replaced.

#2 Clear Supply Return Vents

Supply return vents pull air out of rooms that need to be heated or cooled. However, many homeowners make the mistake of blocking them with furniture. Obstructed supply return vents force your HVAC system to work harder, eventually causing it to fail. To avoid expensive HVAC repairs, make sure that nothing is obstructing the supply return vents.

#3 Check the Exterior of the Heat Pump

Check the side of the heat pump that is exposed to the outdoors. Through the seasons, dirt and debris can accumulate on the unit and significantly impact its efficiency. Regularly hose down the exterior to get rid of branches, twigs, leaves, and others that may have encroached on the unit.

#4 Inspect the Refrigerant Levels

Before summer comes, inspect the refrigerant levels on your air conditioning (AC) unit. If the refrigerant level is low, your AC unit won’t be able to produce cold air. Call a professional technician to inspect the unit for leaks. Leaking refrigerants can be toxic when inhaled.

#5 Calibrate Your Thermostat

Is your thermostat reading the temperature accurately? A properly calibrated thermostat allows it to communicate with your HVAC system. Ask a technician to inspect your thermostat to see if it is functioning properly. You should also consider upgrading to a smart thermostat, which allows you to control the temperature remotely, guaranteeing more energy savings.

#6 Insulate the Attic

Before the cold season comes, make sure that your home’s attic is well insulated. This keeps your home warmer, and in turn, reduces the load on your HVAC system. Check your attic for air leaks, gaps, and holes that may allow cold air to enter. These are usually found around wiring holes, soffits, furnace flues, and windows. Seal these using silicone or heat-resistant caulk.

Schedule Regular HVAC Maintenance

The most important thing that you can do for your home’s HVAC system is by scheduling regular maintenance. In general, HVAC systems should be inspected every six months. By hiring professional technicians to conduct a full check of your HVAC unit, you can extend its life and ensure quality heating and cooling throughout any season.
