Why is it essential to change HVAC filters?


hvac phoenix-6People think that air filter is an unimportant part of the HVAC system, but it is a must to have a good air filter to get quality air flow: the cleaner air filter, the more efficient system. Clogged or dirty air filters make the HVAC system operate harder than usual which means you will have to pay high electricity bills and less efficiency.


Some people think that little dust improves air filtration. But it is not a good thing. Loading less efficient filters make them more efficient, becuase the fibers are becoming smaller and smaller after filling the pores, and it means that it begins to catch smaller particles. In record time, it is getting clogged, and because of that, the airflow is restricted by dust soon.


A proper maintenance planning can be the best option. You should clean or change the filter regularly if you notice that the performance of the HVAC system is decreasing.


It is not a good idea to try to prolong the lifetime of the filters. You will waste money on high energy costs, and the money that you may save on filters is not going to compensate for the electricity expenses. If someone in your family suffers from respiratory issues, this option makes everything harder for them as well.

Filter sizes


It is essential to purchasing a right-sized filter because there are not many ways to maneuver. Either the HVAC filters fit, or it is impossible to place them. The thickness of the most filters equals one inch, but some of them are two or four inches. Some believe that the thicker the air filter, the better air filtration. It is not always true. For instance, if a one-inch filter fits your HVAC system, a four-inch filter cannot be used in the HVAC system without some severe changes. Using thick HVAC filters can even decrease efficiency.


You should make sure that the size of the filters that you are going to replace or your filters are the proper matches. Wrong sized air filters have a significant impact on HVAC efficiency.

On the market, you can find two types of HVAC filters in Phoenix: 1”, 2” and 4” standard sized filters.
