Everything You Need to Know About Furnace Filters

February 9, 2022 | Blog

Did you know that your furnace filter plays a key role in keeping your home clean? Maybe you’ve heard the term furnace filter, but aren’t sure what it is or where to find it? Have no fear, at Big Mountain Heating and Air, we’re here to answer all of your questions.

We pride ourselves on knowing just about everything there is to know about heating systems and we’re here to pass on the knowledge. We’ve compiled a list of common questions about furnace filters and our answers. Read below to learn more!

Are Furnace Filters The Same As Air Filters?

Are furnace filters and air filters the same thing? Well as it turns out, it depends on what kind of system you have. Air filters and furnace filters perform the same function, trapping contaminants as air cycles through them, but they may not always live in the same place.

In older homes, heating and air systems are not always consolidated. Some newer homes have integrated systems, but most homes have separate systems, meaning you’ll need a separate filter for your furnace.

Where Is My Furnace Filter Located?

Your furnace filter is located in the blower compartment of your furnace. The blower compartment can usually be found in a tray or a door on your air blower which will be centrally located in your home.

How Often Do Homeowners Need To Replace Furnace Filters?

The standard for replacing furnace filters is once every 90 days. Of course, this will vary based on how much you use your furnace, the size of your home and the air quality of your home.

Make sure to check your filter and see how it’s doing once a month to avoid degradation of your indoor air quality.

How Can I Replace A Furnace Filter Myself?

To replace a furnace filter yourself, you will first want to identify what type of filter is already in place. Once you’ve bought a new filter, you can replace the old one after first turning off your heating system. Once the filter is in place, you are free to resume using your furnace.

What Our Customers Have To Say

Good Rebates

This is a review for a complete HVAC system replacement from Big Mountain. I started at the SMUD website looking for the best rebate program and found a list of contractors there. I vetted out companies that had a lower number of completed jobs per the SMUD rebate program data.

Very Professional

Had my A/C go out yesterday, called Big Mountain today and they had a serviceman in my area of Lincoln, he was here within a half hour and fix my unit in a very professional manner, and the cost was reasonable. I was very impressed with the company and the serviceman.

I had a appointment with them between 1-3 and one of their staff members called me and kept me updated when they will arrive which was nice. Steve arrived on time and was really nice for explaining what could the cause be. My ac fan was working but cool air wasn’t coming out.
