Changing the air filter on your furnace is not a difficult task, but one that needs to be done a regular basis. The disposable cheaper filters (EZ flow brand $1 each) last approximately 1-2 months. A higher quality 3M filter costs about $20 and lasts roughly 2-3 months. There are also non disposable air filters that are washable, and you should clean wash those every month.

How to Find the Right Size Filter

Find the right size by writing down the model number of your furnace, and then, when you are searching for the air filter in a store or online, make sure the model number is listed on the specific air filter. That way you know it was designed to fit in your furnace. On many occasions, all that is needed is the dimensions of the air filter.

Installing your Air Filter

This may sound simplistic, but follow the directions! Also, be sure to us the arrows commonly found on the filters when you install it in order to get the best performance possible.
Once you install one filter, you will understand how easy it is to do. So, stay on top of replacing them! When they are dirty, all the air in your house is passed through an unclean screen (see below for an example).

Why is it important to change Your Air Filter?

The most obvious reason is that these handy products filter the air that you and your family breathes. That is reason enough to stay on top of regularly changing them, but a clean air filter can also help maintain airflow in heating and cooling systems. This helps to lessen the stress on the system and reduce the amount of energy needed to reach your preferred indoor air temperatures.

So, there you have it. Changing your air filters keeps the air you breathe more healthy, and reduces your energy bill!

Let’s be honest: Nobody thinks about their plumbing and heating until there’s a problem.

What most people don’t realize is that most of those problems can be anticipated and often avoided with regular maintenance – usually at a far lower cost than a repair or replacement.

“This past week I had the need for a plumber and I reviewed the telephone book and selected from the advertisements your company to attend to the matter. The company sent Austin Steinbach to attend to and review the problem. He is a very knowledgeable young man who communicates well and does his work in a very thorough and professional manner. I was very satisfied with his service. Mr. Steinbech is a credit to your company. Very often in communities someone asks whether they are aware of a plumber or other technician that can be recommended. In this regard, I am comfortable in recommending Mr. Steinbech and your company. Thank you for the service rendered.”

“Quick & competent work done to high satisfaction. Darrell Begay provided quick service and very professional work when he came to install a new toilet seat. We had not been able to do the work ourselves, so it was a relief to have Darrell and Done Plumbing get here so quickly to take care of the task. We appreciate all Done as done for us”

“Just a note of thanks for being the Best plumbing and heating company. I have used you often and have been impressed every time. I called for a drain cleaning and was told a technician could come the same day. He arrived an hour ealier than was quoted, was very professional and did a great job at a very reasonable price with my coupon that he honored. I would never use another company and would recommend you to anybody that needs help. The technician that did such a great job was Austin, but every technician you have sent has been the best. Thanks again for such a wonderful company”

~ Karla W Golden, CO

“It was very professional, prompt & the technician explained many things well. Very happy throughout the whole process – from the customer service rep who answered the phone this morning to the technician explaining building codes to me.
