Fall in Arizona means a steady drop in temperatures, especially at night. That makes it the perfect time to make a plan for furnace maintenance.

When you set a regular schedule you can improve indoor air quality and save money on all winter long.

Problems Caused by Dirty Furnace Filters

A furnace with air filters that are clogged with dust, grime and dirt won’t work properly.

When the airflow is restricted, the heat in the heat exchanger gets too high. Every furnace is designed to shut off the burners when the temperature exceeds a certain level.

Usually, a furnace will automatically reset when the heat exchanger cools down. But, if you don’t correct the problem, it will keep happening. It can lead to a service call to diagnose the problem or replace a ruined part.

Energy Star and HVAC professionals recommend you change your furnace filter every month to avoid this problem.

Benefits of Changing Filters

Here are the good things that happen when you change your filters each month.

System Will Last Longer

Did you know the most common reason a heating and cooling system breaks down is because of a dirty filter?

It happens when dirt builds up to the point where air can’t pass through the filter. The system can overheat, and the motor has to work harder.

If you’re lucky, your unit will only need repairs. But, if you have an older unit, you could ruin the system. You could be looking at buying a new system.

Replacing the filter is an easy way to extend the life of your heating system.

Reduce Energy Costs

The Department of Energy says heating and cooling account for about 48% of the energy use in a typical U.S. home. That’s a significant expense.

If the air filter is clogged, the system has to use more energy to produce results. And when more energy is used, it increases the cost of your energy bill.

Change furnace filters regularly and your system will run efficiently. That will save you money on your utility costs.

Improve Air Quality

If anyone in your home suffers from allergies or asthma, clean air is essential for their health. Dirty air filters reduce air quality and can aggravate symptoms.

If you have pets, pet dander will accumulate in the system and spread allergens throughout your home.

Replace your furnace filter each month to prevent your indoor air quality from deteriorating.

Keep Your System Clean

Dirt clogged up in the filter can infect your entire system. It can result in extra repairs, service, and parts that you weren’t expecting.

Replacing your filter is an easy, inexpensive way to keep your system clean. It pays off by extending the life of your unit, saving you money, and improving your home’s air quality.

Contact the Experts

Besides changing your filter every month, it’s important to get an HVAC tuneup and regular maintenance at the start of the winter season.
