When was the last time you looked at your furnace? If you’re like most people, you assume the furnace is fine and ignore it until a problem arises. Did you know something as simple as changing HVAC filter can improve the lifespan of your furnace?

The filter is an inexpensive part of your HVAC system, but it’s vital to its proper working and your health. An HVAC filter change only takes a few minutes. If you don’t change it, then it can lead to many problems down the road. 

We’ll look at what the filters do and what happens if they are changed every 30 to 60 days. 

Changing HVAC Filter Saves Your Motor 

When your HVAC system is on, it takes air from inside or outside the home and circulates it into the HVAC system for heating or cooling. The filter catches particulates from the air that come through, so they are not sent into the HVAC system. 

If the filter isn’t changed, then the particulates cover the filter and not as much air gets through. Without enough air, your HVAC system’s motor works harder to bring air into the furnace or AC. 

This adds unneeded wear and tear on the motor and could lead to an eventual breakdown. Change air filter HVAC systems to keep your motor healthy. 

Clogged Filters Lead to High Energy Bills 

You may have asked, “How to change HVAC filter,” and many times it’s as simple as opening the filter area, taking out the older filter, and then replacing it with the new one. Dust, pet hair, and other particulates clog the filter, and as we mentioned how the motor works harder. 

This means the HVAC system runs harder and longer than it needs to. This could lead to a significant jump in your utility bills because of the increased usage. It needs to send the air throughout the entire home, and if it’s clogged there isn’t as much air to send out. 

It Could Lead to a New Furnace 

A new air filter for your HVAC system could be anywhere from a few dollars to $40 depending on the type you need. This is nothing when compared to the cost of a new furnace, which is several thousand dollars. 

When the air filter is clogged, it impacts more than just the motor. Particulates could seep through and damage other parts of the furnace. Over time, it can wreak havoc on your whole HVAC system and lead to a complete breakdown. 

A new furnace can last several decades if taken care of, but not replacing the air filter regularly can shorten its lifespan. No one wants to buy a new furnace, so change the filter when needed. 

Change Your HVAC Filter 

You can’t afford not changing HVAC filter on a regular basis. It can lead to a breakdown at the worst possible time. You don’t want to be in the middle of a blizzard and have your furnace go out.
