How often to change your hvac filter?

In general, most air filter manufacturers and HVAC companies recommend changing the air filter every 90 days or 3 months. That may change depending on the location of your home (e.g. EJ. dry and dusty climates), if you have pets and the age of your system and equipment.

The only way to ensure how often you need to change your air filter is to perform a visual inspection of the filter every month. After a few months, you'll get an idea of how quickly it gets dirty. You will need to re-evaluate if you have a new pet or if the outdoor air quality has been poor. The ideal is to change your air filter every three months, however, there are certain factors to consider when determining when to change an old filter.

The basic consensus among HVAC professionals is that you should replace your oven filter every 90 days or every three months. However, that depends on the thickness of the filter. Thicker filters have more room to pick up dirt and dust, so there's no need to change them as often. Thomas %26 Galbraith Heating, Cooling and Plumbing of Ohio recommends replacing filters that are less than 2 inches thick every 30 to 90 days.

Three- or 4-inch filters can last 6 to 9 months, and filters up to 6 inches thick can be replaced once a year. A general rule of thumb for pleated air filters (such as those manufactured by FilterBuy) is to replace the filter every 90 days. As the filter traps more dirt, dust and allergens from the air, the efficiency of the filter decreases. Find out below if you should replace the filter more often.

If the dirty air filter is completely covered with dust and dirt, it is a good idea to change the filter even if it has not reached the end of its recommended life. Whether it's oven filters, air filters, or any other part of your unit, be sure to take care of your HVAC system to extend its life. And in doing so, the HVAC air filter will work twice as hard to overcome these barriers, making the unit less energy efficient. If there is no smoker or pets in your home, and your filter is the 1 filter that is commonly sold with a MERV rating of 4, you should be able to wait up to 90 days before changing it.

A vacation home where you only live part-time, for example, will need far fewer filter changes than a large family home with numerous occupants. During mild spring and fall, your HVAC system will operate less frequently, so the filter won't get dirty as quickly. Larger homes have large volumes of air circulating around them, which means that the filter may need to be changed more frequently. Furnaces and air conditioners in smaller homes need to pump less air for the same amount of temperature change, which can mean less frequent filter changes.

How often you change your home's HVAC air filter depends on how long the filter is expected to last and the different qualities in your home that affect the filter. However, if your HVAC system works almost constantly, change the filter every few weeks (especially if you use a cheaper fiberglass filter). However, these appliances are often built with smaller filters and, therefore, may need to be changed as often as a filter in a larger home. If you have small children at home, it's a good idea to use high-quality pleated air filters and change them every two months.

In summer and winter peaks, air filters should be changed more often than necessary during the spring, fall, and milder months. To ensure that only clean air comes out of your HVAC system, replace the air filter before it becomes clogged so you can breathe better. Therefore, in addition to causing breakdowns, it can also increase energy bills because the HVAC system has to work overtime. They also generate less air resistance, which can help the HVAC system operate more effectively and reduce wear and tear on components, including the fan motor.
