With the constantly rising cost of energy, we all try to save energy in any way we can. Since heating and cooling make up about 50% of our energy bills. Just by changing your HVAC filter can improve the efficiency of your HVAC equipment by 5% to 15%.
Most people will change their filters at the start of a new season, when they know the equipment is going to be working its hardest. Some people, on the other hand, change it once a month – just to be on the safe side. What are the factors that determine how often the air filter should be changed?
- What type of air filter do you have? Since each type has a different life span, use that to help determine how often to change it.
- What is the air quality like in the house? If the air does not seem as clear or fresh as it used to, or you are having issues with allergies or frequent colds, you may need to replace your filter more often or choose a different type.
- Are there pets in the house? If you have pets in the home, you may want to consider changing filters more frequently or choosing a type that helps with dander.
- How many people are in the home? The more people in the home, the more dust and dirt flies around – consider changing your filters more often.
- Are you in an area with high construction or pollution? If the answer is yes to either of these, check your filters frequently and make sure to change them when they are dirty.
Keeping all the above factors in mind, your filters should basically be changed when they are dirty. While this may seem like generic advice, it all depends on the living condition in your home, the type of filters used, and how often and how hard your HVAC equipment is used. In unusually hot summers or cold winters, the filters are going to need checking more often. A good rule of thumb is check them once a month.
