Tips to Extend the Life of Your HVAC

4 Tips to Extend the Life of Your HVAC System


An HVAC system is a large investment, and your furnace and air conditioner are some of the most important appliances in your home.

Naturally, you’d like to get as many years of service out of your HVAC system as possible.

Homeowners and members of the household often have a bigger impact on HVAC system life than they realize.

These tips can help you keep your central heating and air running smoothly for many years.


1. Reduce Heat and AC Usage

Nothing will have a bigger impact on slowing HVAC wear and tear than using the system less often.

However, this doesn’t mean you have to be uncomfortable.

There are several ways you can supplement your heating and AC when the temperature outside is not too hot or cold.

If you’re looking to reduce AC usage, the first thing you should try is installing thick blinds or drapes to keep more of the sun’s heat outside.

You can also try to postpone cooking and using other heat-generating appliances until the evening when it’s cooler.

The best ways to supplement your furnace are with alternative heating sources such as a fireplace or by bundling up with blankets and warm clothes.

Ceiling fans can be helpful for reducing your HVAC system usage year-round.

Running fans counter-clockwise will create a cooling effect in warm weather, while running them clockwise will help to distribute heat when it’s cold.

Similarly, adding insulation to your home is a great way to reduce both your heating and cooling needs.


2.Maintain Adequate Airflow

Many of the maintenance tasks that homeowners can perform on their HVAC system are intended to maintain proper airflow.

This is important because restricted airflow forces the blower motor to work harder and reduces system life.

You should clean or replace your furnace filter each month to avoid an airflow bottleneck from a clogged filter.

Like the furnace filter, the outdoor condenser is important to maintaining good airflow.

Make sure the space around the condenser is free of vegetation or debris.

Make a habit of shutting off the condenser and cleaning it with a stiff brush or garden hose to prevent dirt from clogging the unit.

Additionally, inspect the exterior of the condenser for bent fins and straighten them with a butter knife or fine comb.


3. Set Your Thermostat to Auto

It may seem strange that a specific setting can have such an impact, but this one deserves mentioning on its own.

Most thermostats have a two-way switch labeled On and Auto that controls the behavior of the blower fan.

When the thermostat is set to On, the fan will run constantly, while Auto only allows the fan to run when the system is actively heating or cooling your home.

As you would imagine, letting the blower fan run indefinitely can wear the motor much more quickly than only using the fan occasionally.

For this reason, most HVAC contractors recommend that you strictly use the Auto setting unless you have a device such as a whole-home humidifier or purifier that benefits from a constant flow of air.


4. Remember Yearly Tune-Ups

No matter how dedicated you are to maintaining your HVAC system, some tasks simply must be performed by a professional.

Examples include checking and charging refrigerant levels, repairing or replacing internal components, and lubricating motors and bearings.

A yearly tune-up from an HVAC contractor is essential to ensure you get the maximum lifespan out of your furnace and air conditioner.

Maintaining your furnace and air conditioner is a wise goal that you will thank yourself for later.
