Why, When, and How, Everything You Need to Know About Changing Your Air Filters

Is it Really Even Important To Change My Air Filter?

Air filters are very important! In fact, they are the top reason we get called in for a service. Dirty filters restrict the airflow through your duct work and make the system work much harder, it’s like driving your car with one foot on the break and one on the gas pedal. This will not only overwork your system, it will also raise your energy bill considerably and may also damage your unit beyond repair. We can’t count the number of units we’ve replaced because the filters didn’t get changed enough!

How Often Do I Need to Change My Filters, And How Do I Do It?

You should change your air filter every ninety days, that’s only four times a year, and it could save you thousands in energy bills and costs for repair and replacement.

To change your filter, first you need to find it.

For some units, believe it or not, the filter is actually right on the inside unit. The unit will have a small door on it about an inch or so tall, that’s where the filter will be if it’s on your unit. For others, the filter can be found at the return vents. Just take off the cover and see if your filter is there. If your inside unit is in a particularly difficult place to get to, such as an attic or crawlspace, I would check here first. Usually if the filter is here, there is some kind of easy release for the grate.

So now that you’ve found your filter, take it out and see what size you need, the filters will usually say on them what size they are. You can purchase a new one at Walmart, Home Depot, Roweton’s, etc. Once you have your new filter, just put it in where it was before, close it up and you’re good to go for another 3 months! It’s that simple!

Help! None of These Stores Have The Right Size!

There are tons of different sizes of air handlers and vents, so it kind of makes since that you can’t always find the one you need, our best advice is to get one that’s too big and cut it. Yep, you can do that. Measure it to the size you need then grab a pair of scissors and cut it up. Put it where you took out the old one, and you’re good to go. Another way if you don’t want to cut your own, call us over hear at David’s Heating and Cooling and we will get a hold of a supplier who can get you the size you need!
