There isn’t one correct answer when it comes to changing your HVAC filter. The life of a filter’s time frame depends on the type, quality, brand, etc. Some filters should be replaced once a month, others every other, higher quality filters can efficiently last for up to 90 days. If you’re unsure of what filters you currently have or seem to forget how long it’s been since you last replaced them, it’s a good idea of what signs to look out for that can tell you when a new filter needs to be installed. Please keep reading to know when your HVAC system tells you it needs a filter replacement.
High Electricity Bill:
There are a number of reasons that your electricity bill might drastically increase. However, one of the simpler causes is that your air filter is dirty and needs to be replaced. When your air filter is full of dust and can no longer filter your air properly, it interferes and lessens your home’s airflow efficiency. This may cause you to turn up your AC and make your system work harder to bring your home to the temperature you prefer.
The Filter Itself Looks Dirty:
The easiest way to determine if your filter needs replacement is simply by looking at it. Is it covered with dust and other air particles? Is it brown or black, unrecognizable from the white filter you initially installed? Chances are, it’s time to install a new filter. Make a habit of checking your filter every month to ensure it’s doing its job effectively, filtering the air in your home, and keep a few extra filters on hand to replace it as needed.
Allergies Are Kicking In:
While your allergies might be caused by pollen in the air or a new season of plants outside, it might be the air in your own home causing you the sniffles. The purpose of your filter is to filter out dust, grime, and potential allergens from the air you’re breathing at home. Pay attention to if your allergies align with your regular seasonal allergies or if they seem to have appeared out of nowhere. Instead of buying medication for your allergies, you might be able to solve the problem with a new filter and completely eliminate your symptoms overnight.
Air Vents Covered in Dust:
Are you constantly spending time dusting your air vents? If you find thick layers of dust sitting on your air vent, it’s more than likely due to your air filter desperately needing to be replaced. When dust fails to be caught by your air filter, it tends to make itself at home in, on, and around your air vents. Replace your filter and take dusting or wiping down your air vent off your to-do list!
