HVAC units are usually some of the largest pieces of machinery in your home. While there are a lot of things that need to be done to maintain your HVAC system, most of them require the help of a professional.
The good news is that perhaps the most important regular maintenance your system will need is to have the air filter changed. And that’s something that you can easily do on your own.
Why Do Air Filters Need to Be Changed Regularly?
Help Your Family Breath Easier
The purpose of home air filters is to trap air-born particles before they enter your HVAC system. If pollen, dust, pet dander and smoke are in your air filter, they can’t make it to your lungs. Breathing clean air is extremely important, especially for those who suffer from allergies or asthma.
Increase Energy Efficiency
Dust, dirt, and animal hair can clog the coils and prevent your system from doing its job efficiently. The longer a system needs to work to get the same amount of clean air, the less efficient the system become and the more expensive it is to run it.
Extend the Life of Your HVAC System
The added strain on the system also means that the fan motor will become more likely to overheat and burn out. Just as your car needs regular oil changes, HVAC units need their air filters replaced. By replacing them regularly you can make sure that you get the longest life possible from your system.
It’s Inexpensive and Easy to Do
Air filters are relatively inexpensive ($10-$50 depending on size and type) and only take a few minutes to replace. This simple maintenance is a small price to pay when compared medical bills, increased energy costs or replacing your entire system.
How Often Should I Change My Home Air Filter?
The simple answer is that you should change your air filters when they’re dirty. How often that is, of course, will depend on a number of factors including the type of filter and the number of pets you have in the home. Most standard air filters recommend that they are changed every 30-90 days.
For the average home without pets, you may be able to change your air filters every 90 days. A cat or a dog will likely mean you should change the air filter at least every 60 days. If you have more than one cat or dog you may be closer to the 30-day range.
