Learn More About Air Filter and the Replacement Cost

dirty air filterYour HVAC unit is not a “set it and forget it” thing. In fact, if you do that you’ll be finding yourself in trouble and in need of an HVAC repair before you know it. This is because air filter replacement is an important component of any heating and cooling system maintenance. Most likely, your HVAC unit uses disposable filters that should be replaced at regular intervals. There are many different air filter replacements available for purchase, through. Which one is right? How much does an air filter cost? What does an air filter even do, anyway? There are a lot of questions!

“Why do I need an air filter replacement?”
First things first, what is the point of one of these replacements anyway? Your HVAC system’s air filter serves a primary role as protector of the system’s blower motor. The air filter works to keep the blower motor clean. It does this by removing airborne contaminants passing through the system. Without this air filter, all the allergens, dirt, dust, hair, and other particles would pass into the blower motor chamber from the return ducting and settle on the blower motor. These contaminants would accumulate and eventually cause damage to the blower and other components within your HVAC system. As an air filter creates a cleaner blower motor and compartment, it also creates cleaner indoor air for you and your family through contaminant removal. This is an incredibly valuable benefit they provide to your health and happiness.

“How do I know which size I need?”
Different systems require different-sized filters. Your equipment owner’s manual should provide filter sizing info, but often the quickest and easiest way to find the right size air filter replacement is to look at the existing filter. Take it down and measure it!

“How much does an air filter replacement cost?”
Not a lot! Furnace air filter cost varies from one product to the next. The MERV rating, filter material, thickness, retailer, and other factors will affect the price you pay. A standard disposable 1” air filter replacement costs as little as a few dollars, but it will only do its job well for about a month. A 6” pleated filter that doesn’t need to be changed more often than every nine to 12 months has a higher price tag attached, but delivers better value. The choice is yours!

“How often do I need to change it?
As stated above, part of this answer has to do with which filter is currently being used. A cheaper filter must be replaced more often. There are also other factors to consider, like how many people and pets live in your home, how often your HVAC system runs, and other air quality issues present in your home. In general, around every three months you should pop a new filter in.

Never miss replacing your air filter when it is time! Skipping air filter replacement and continuing to operate your HVAC system with a dirty filter has the potential to cause serious problems with system performance, like overheating and poor air quality.
