Furnace Filter Changing – A Must

Did you know your furnace has filters????

Have you changed your furnace filter lately? Did you even know that your furnace  HAS a filter?  All brands of  furnaces, whether Tempstar, Trane, Carrier, Rheem.  Well, if your like me I have to admit that when I purchased my first home I had no idea.  Now that I am “in the know” each time the motor starts up, it starts drawing in air to heat (or cool). That air goes through a filter first to screen out air debris that would otherwise get into the motor and damage it.

Your filter works like the screen on a window, trapping the stuff you don’t want to get through. Those filters catch all kinds of pet hair, people hair,dust and dirt. If you really want to know it is also the skin flakes that we all shed every day.  Eventually building up until it’s hard for the air to get through.  Once the filter is clogged, the motor has to work harder to pull in enough air. That’s causes a lot of stress on the motor, and eventually, it will burn out.

Your furnace is designed to work with a steady supply of clean air. Once your filter  get full, the only thing to do is to change them for new, clean ones.  Okay, now you have to get to your filters. If you are unsure what kind or type or just want help installing, that is where you give Comfort Zone tech a call and we will gladly help. the very first thing you do is TURN OFF THE  ELECTRICITY!! You may be laughing right now, but trust me all information given is good information – at least in this blog!! If you pre-purchased filters go to your furnace, it’ll have a panel (usually near the bottom) that comes off without tools. If your furnace is built into a wall, it may have two panels. DON’T unscrew anything! The access panel you’re looking for is meant to come off easily, so that you can change these filters. If you have to use tools, you’re probably looking in the wrong area.  Trust me, I have done this mistake also!!

Inside you look for a set of metal grooves holding a cardboard-framed rectangle. The size will be different for each furnace, but 12-20 inches on one side and 18-30 on the other is common range.  They are usually 1″ thick.

Find that, and slide it out of the metal grooves. (Double check whether there’s a second one on the opposite side, so you can get that one too.) Before you throw it away, look for markings on it. That’s how you’ll know what size to replace it with. It’ll have all three dimensions in inches, and look something like this: “14 x 20 x 1”.  Once you’ve got the new filters in place, put the access panels back on. Then turn the power back on.

Keeping your furnace loaded with clean filters has one of the biggest payoffs in preventative maintenance. For a dollar or so every few months, you can greatly reduce the stress on your furnace’s motor, making it last years longer. And along the way, you’ll pay lower energy bills because your furnace isn’t working as hard.
