Okay, some of you may be thinking “how difficult can it be?” Or maybe “who doesn’t know how to do that?” Just hear us out. Believe it or not, a lot of people do not know how to change their AC filter! We have even been on calls where the owner or renter was unaware they needed to change the AC filter!
No need to worry, Coast to Coast Heating & Air is here to help! If you don’t know how to change your disposable AC filter this article is for you! If you didn’t even know what an AC filter was or that you have to change it…We are glad you found this article and you may need to give us a call!
First, let’s talk about what an air conditioner’s filter is and what purpose it serves.
What is an AC Filter?
An AC filter is just that, a filter. It improves the air quality in your home while simultaneously preventing buildup of dust and grime on your air conditioner’s coils. It basically collects all of the dust and grime that you don’t want floating around your home. If you don’t change your air filter frequently, it will significantly decrease the air quality. If you or a loved one have asthma or any lung issues, this can make those issues worse.
Another issue that arises from not changing your AC filter frequently is the unit’s efficiency. Keep in mind that having animals in your home means your filter will clog up faster. When your AC filter becomes heavy with dirt & dust, it clogs up. This prohibits your air conditioner from working efficiently. You may notice the unit is working harder with nothing to show for it. AKA your unit isn’t cooling as well as it used to. This results in a higher electric bill for you without having a cooler home. Essentially wasted energy = wasted money!
How Often Should I Change My AC Filter?
We recommend you check your AC filter every 30 days. When checking the filter, if it appears to be in good shape, not clogged or covered in dust, leaving it for another 30 days should be okay, though it is not recommended. If the filter does not appear to be in good shape, change it ASAP.
You want your unit to run the most efficiently, so changing the filter every 30 days would be your best option. Energy Star recommends you change your AC filter every month during Summer – which is a big chunk of our year down here in Florida! Going more than 60 days without changing your air conditioner’s filter can be detrimental to the functionality of your unit.
To relate it to what was stated in the previous section, not changing your AC filter frequently will result in your AC unit working far less efficiently. This means your chance of needing AC maintenance or AC repairs will increase significantly. Don’t get us wrong, we’d love to see you more! However, you can prevent this wear and tear on your unit.
Spending between $2 – $20 (depending on the filter your unit needs) per month could save you hundreds in AC maintenance or repair, in addition to your monthly electric bill savings.
Do Different Units Needs Different Filters?
Yes!!! Believe it or not some filters can be too good for your unit, otherwise known as having a high MERV (Minimum Efficiency Reporting Value) rating. This means they create to much restriction. Your air conditioning unit is trying to pull air through the filter. If the filter is too dense, your unit will have to work much harder to pull the air through. Filters come in many different MERV ratings. It is best to consult with your AC company to ensure you are buying the right AC filter for your unit.
How Do I Change My AC Filter?
Now, here is what you came to this article for! Step-by-step instructions on how to change your air conditioner’s filter.
Locate your filter. Your AC filter can be in several different locations. By far the easiest way to locate your filter is by speaking with your AC company. You can do this at the same time you ask which filter is best for your unit.
Turn off the power to your unit! This is a safety precaution. Your safety, and the unit’s. You don’t want to be electrocuted, and if you remove the clogged filter while the unit is running, the debris can get sucked into the unit!
Remove the AC filter. If you hold the filter up to the light and can’t see much light coming through, it’s time for a change!
Insert the new filter. Be sure to insert the AC filter the same way. There should be an arrow on the filter’s frame that shows the direction the air should flow through the filter. The air should always flow towards the air handler/furnace.
That’s it! Four simple steps. If you have any questions or run into any problems while replacing your filter, please give us a call! We would be more than happy to assist you! (352) 229-6221
