Take the guesswork out of changing your furnace filter with tips that make it easy to remember when and how to change it. Furnace replacement filters help keep your furnace running efficiently and your indoor air quality at optimum. Here’s what you need to know:
WHEN DO I CHANGE MY FURNACE FILTER?
We recommend changing 2” and 4” filters every 90 days, and standard 1” filters every 30 days. Bob’s Heating makes it easy to remember when it’s time to change your filter with our Filter Replacement Programs because we’ll send a filter to your door every 90 days. All you need to do is input your filter information once, and then choose whether you’d like the 1-year or 3-year program. Then you can sit back and forget about furnace filters until the next replacement arrives at your door!
WHICH FILTER DO I BUY, AND WHERE?
While you can purchase standard 1” filters at home improvement stores or at www.BobsHeating.com, Bob’s Heating recommends and uses 4” filters on all furnaces we install. We find the 4” pleated filter helps promote better indoor air quality and better system efficiency and overall function. These are the exact filters we send to you in our Filter Replacement Programs.
