Top 7 Tips on Extending An HVAC System’s Lifespan


One of your main worries is probably extending the life of your HVAC system. And it should be because this is one of the most significant investments you’ll make for your home. Here are some of the top pointers on how to make your HVAC system last longer and where to find heating and AC service in Alabama: 

Schedule Preventive Maintenance

The best method to extend the life of your HVAC unit is to schedule annual or bi-annual maintenance. Your service professional will clean, inspect, and tune up your system.

Internal cleanliness is just as vital as external cleaning. It entails looking for trash, dampness, or shavings that should not be there. Your item’s connections, cables, and mechanisms will be thoroughly examined. A new filter, lubrication, condenser cleaning, and a check of the electrical system are all part of the tune-up phase of the maintenance.

If you don’t maintain your HVAC system properly, it’s more likely to break down due to little difficulties that grow into major problems. If the engine burns out due to a blocked filter that prevents air from flowing into the unit, you may need an immediate HVAC repair, or you’ll have to replace the entire system.

Make Use Of The Auto-Selection Feature

Your HVAC unit’s fan will likely have an “auto” and an “on” setting. The fan is only started when the system is actively heating or cooling the house when the “auto” option is selected. The “on” setting keeps the fan running, consuming more energy and putting more strain on your system. As a result, you should strive to save money by using the auto setting as much as possible.

Make The Switch To A Smart Thermostat

Smart thermostats let you control your house’s temperature at specific times. You can set it to save energy or use it to access it from your phone or tablet. Changing the temperature depending on the number of people in the room will save energy and money. Consequently, you’ll save money on your utility costs, and your unit’s lifespan will be extended.

Use Alternative Heating and Cooling Techniques

Use ceiling fans in hot weather to relieve your HVAC system and add reflecting shades to keep the heat from entering your home. Set the thermostat to a higher setting to make your system work less to cool your home.

Put on a sweatshirt and open the blinds when it’s cool outside. Allow the sun to assist in the heating of your home. Reduce the load on your HVAC system by lowering the thermostat, wrapping oneself in a blanket, and adding space heaters to chilly rooms.

Keep An Eye On The Condenser

The HVAC system’s condenser unit is located outside of your home. As a result, it is vulnerable to damage from extreme weather and windblown debris.

Check it regularly and clear away any weeds or garbage. Tree roots and plants grown too close together might cause problems for the unit. Keep an eye on the landscape for proper drainage and rust or other noticeable damage.

Examine The Insulation In Your Home

By minimizing the need for your HVAC system to run constantly, adequate insulation can help it last longer. The attic is the most likely place for heat and air to escape. As a result, improving the insulation in this area will aid in lowering the quantity of heat and air produced by your HVAC unit. This can be aided by insulating the basement and providing more insulation to the walls.

Regularly Replace The Air Filter

A 30-day or 90-day filter can be used in your HVAC system. Whichever option you choose, inspect it frequently and replace it as needed. Many on the market will filter out a significant amount of dirt, pollen, and bacteria in the air. 

Follow the filter change schedule provided by the manufacturer. If you have pets, you should replace your filter more frequently. As a result, you’ll avoid having their fur and dander bother you.
