What Are Some Factors Influencing How Often I Should Change The Filter

How often do I change my AC’s air filter?

There are many different factors which will affect how often you will need to change your air conditioning filter:

  • Pets shedding of pet fur can mean that your filters will become more blocked more frequently. The more pets in the building means the more often your filters will need replacing, at least every 2 months.
  • Frequency the more your aircon is used means that the more often filters will need replacing. If your system is used rarely then a filter can last several months and up to a year. But if the unit is constantly in use then every 1-2 months is when the system should be replaced.
  • Size the larger the building means that the system will need to work harder to keep constant air quality. At the same time, smaller aircons will have smaller filters which also means that they will need replacing more often.
  • Allergies or Asthma if there are people who work or live in a building with respiratory problems then the filter will need to be replaced every 6 weeks.

Signs You Need A New Ac Filter

Youre usually fairly safe changing your AC filter once every 30 to 90 days. It probably wont hurt much to let a dirty filter stay for a while. But if you want an optimally clean home, you need to replace the filter the second it stops being functional.

So, to help, here are some signs that its time for a change.

Increase In The Dust Around The Air Vents

Your HVAC filters may be clogged if you see a build-up of dust around your air vents. You may do the white sheet test to see whether your filters are dirty. For an hour, just lay a clean white sheet approximately five inches away from the vents. If the sheet ends up with dust and other particles on it, your HVAC system could use a good cleaning.

Why Changing Your Hvac Filter Is Important

Air filters are only meant to last for a set amount of time , so you need to be taking note of that date when you install them.

” could have adverse effects on your HVAC equipment and your comfort,” Van Deventer explains. “If it goes too long, filters can load too much and collapse, and that can be really bad cause you may not know it. it could get lodged in your fan, or create a big gap where air just goes around the filter and doesn’t get filtered in at all at that point.”If your filter isn’t actually filtering, it can affect your health and cause breathing issues, especially for people with allergies or asthma.

Where Is Your Hvac Air Filter Located

How To Change Air Conditioner Filter In House

Depending on the size of your home and its number of air conditioning units, your HVAC system could pull air from one or more locations around your home. You will need to inspect each of these locations to determine how many air filters you need to replace every 30 to 90 days.

The most common locations for HVAC air filters are:

  • Horizontal HVAC units typically have air filters located in a slot at the side of the unit.
  • Vertical HVAC units typically have air filters located in a slot above or below the unit.
  • Other HVAC systems use air filters located in your homes walls, ceiling, or utility closets. You can usually find them behind a removable grill or grate.

If your HVAC system has a return in each room, you may need to replace multiple filters as part of your regular HVAC maintenance.

Follow The Instructions But Do It Even Sooner

When you buy a new filter, the packaging will state how long it should last. But don’t wait until that date to change it! Van Deventer says you should take that date as “the absolute maximum” and change your filter even earlier.

“Essentially, the way that most of those filters operate is they have a porous media that captures the particulates and that blocks the airflow,” he explains. They actually filter a little better the longer they’re in. But it also starts to really restrict the air flow on your system], which can cause other issues.”

“Anytime you’re aware of more pollutants or particles in the air is a good time to change your filter,” Van Deventer says. Allergy and flu seasons, for example, are good times to upgrade to high efficiency filters! And if you have any kind of home renovation going on that could kick up more dust and dirt than usual.

“I would say if there’s any kind of home renovation where there’s drywallthat that’s a huge one that sometimes people don’t realize will get sucked into air returns and immediately block up your filter,” he notes. “I’d also say during summer months, if you’ve got pets and they’re just shedding a lot more than usual, that’s a good time.”

If you need a way to remember, here’s a smart tip: “Anytime you’re finding yourself having to vacuum a lot more, that’d be a good indication that you also need to be checking your filter a lot more as well,” Van Deventer says.

What Are Air Filters And What Are They Used For

Air filters are electronic devices used in homes, offices, or any enclosed space to regulate temperature, pick up dirt and allergens, and control humidity. Invented in 1902 by Willis Carrier, air filters work by transferring unwanted components in the air from indoor spaces to outdoor spaces.

The terms AC and HVAC are often used interchangeably. AC simply refers to air conditioning, while HVAC refers to heating, ventilation, and air conditioning. The major difference between the two is that HVAC has added features like gas furnaces, heat pumps, and air conditioning. Additionally, HVACs work includes ductwork and ventilation.

Which Air Filter Is Best

How Often to Replace Your Car

This rating can be a useful guide for the effectiveness of the filter and consists of a ranking from 1 to 16.

If youre concerned that your current filter might not be as effective as you would like, consider checking the MERV rating.

How Much Does An Air Cabin Filter Replacement Cost

The average cost of a cabin air filter is between $15 and $50, depending on the size of the unit. Labor fees vary per mechanic and garage.

As is the case with more vehicle parts, the cost to replace items is often dependent on the type of vehicle you have. Some luxury brands will charge more for their parts and require that you only buy their branded cabin air filters, while others suggest you can purchase a generic cabin air filter from your local automotive shop.

Some mechanics will recommend you change your cabin air filter during your routine visit to the garage for regular maintenance. Thatâs fine, but make sure you ask to see the filter first. Visually inspect it, and if it looks like it needs replacement, do so. If not, you can always wait for a later date.

Your Frequency Of Using Your Air Conditioner

One of the factors that determine how often you should change your AC filters is how frequently you use the AC. If you use the AC in a rarely used vacation house, you may change the filter once a year. On the other hand, an AC inside a suburban home should be changed at least every 90 days. Consider these additional circumstances as well:

A general rule of the thumb is that you should replace the filter in your HVAC every month. However, other factors change this timeframe. For instance, some months in Palm Harbor FL are hotter than others. You tend to use your AC more during the hot months than during the cooler months. During the months you use it more, make sure you replace the filter in less than one-month intervals.

    Your Electric Bill Has Gone Up Suddenly

    Another sign that it might be time to replace your AC filter is that your electric bill has gone up suddenly. If this has occurred, its probably because your AC is working harder than it usually does. If this is the case, a dirty AC filter could very well be the reason.

    See, when the filter gets dirty, dust and debris have free reign to enter the AC system. To counteract this additional dust and debris, the AC has to work harder than it does typically. This requires more electricity and therefore equals a costlier electricity bill.
