Why It’s Important to Change Your Furnace Filter Regularly

furnace filterThere are three main reasons to regularly change your furnace filter. The first is comfort, the second is running costs, and the third is repair or replacement costs. To help you understand that in a little more detail, let’s look at each one.


It doesn’t matter whether you are at home or at work you breathe air. Air quality impacts how you, and everyone around you, feel about life. When you’re feeling healthy you move better, feel more active and you want to do more. Feeling good and being active does depend on our overall health, of course, but we can all help ourselves just by changing our furnace filter at the right time.

A filter that is getting clogged with dust, pet dander, pollen and whatever else blows in from outside begins to fail. The filter’s job is to collect anything in the air that you shouldn’t be breathing in, so once the filter begins to clog it becomes less effective. Clogged filters collect less, so they allow more dust, dander and so on to blow through the HVAC system and back into the room. Young and healthy people don’t notice it so much, even though they are still breathing it all in, but older folk or anyone who has COPD, asthma or allergies will really notice that they don’t feel as good as they’d like to.

Running Costs

A clogged filter reduces air flow and makes the motor work harder. The harder the HVAC motor works, the more electricity is uses. The Department of Energy says the average home spends about $2,200 a year on heating and cooling the home. A filter in need of being replaced will burn more than that. A system where the filter is replaced frequently will burn 5% to 15% less than average. Saving a few hundred dollars each year is a big reward for doing something as simple as changing the filter every few weeks.

Repair and Replacement Costs

An HVAC system has an estimated life based on the basic product quality, the way it was installed and how well it is maintained. Once the system is in place, the most important thing is regular HVAC maintenance. The easiest maintenance work you can do is to regularly replace the filter. As you know, clogged filters make the motor work harder. Clogged filters also allow more dirt and dust to settle inside the vents which also makes the motor work harder. This extra work will result in breakdown, and breakdown demands heater repair.

Your heater repair professional at Max Mechanical will come out as soon as possible to assess the overall condition of your system and explain what needs to be done to achieve two goals. One goal is to get it up and running again, and the other is to show you what you can do to extend the system’s life. The easiest thing will be to regularly replace that filter.
