Manufacturers construct furnace filters with the goal that air goes in one direction via the filter medium. This way, the filter does what it’s supposed to do in stopping dust from collecting on motors and blowers inside the furnace. You might ask, “What happens if the air filter is backwards?” While installing an air filter backwards isn’t likely to damage your unit, it can cost you in effectiveness.
Air filters are vital pieces in your total home comfort unit. They keep undesirable sediment and debris out of your indoor air, and they assist your unit in running effortlessly for years. Though, if you’re not cautious, an air filter installed backwards can create quite a few issues with your heating and cooling unit.
The most common issue you will have with a backwards installed filter is inefficiency. If your furnace is forced to blow air via the non-porous part of a filter, it will use more energy to do so. The blower will be overburdened, and your heating bill will increase. The same is also true for an AC that has many filters in place to have outdoor pollutants stay out of your indoor air.
Beyond the cost of incorrect filtering, you will have a reduction in indoor air quality. The filter is built to eliminate undesired debris, but only when installed in a specific direction. If you put your filter in backwards, the usually collective end of the device will not face the air supply. Your filter will aid in keeping debris in the air.
This results in a clogged filter and inaccurately cleaned air getting into your lungs. If you have a home indoor air quality unit, it will help to supplement this issue for a while, but the clog will sooner or later become unbearable for your unit. This is what happens when the air filter is backwards.
How to Avoid This
There are two ways to avoid incorrect air filter installation. First, you can have a professional Rochester heating and cooling install the filter for you. When you need a new filter contact a technician to come and take care of it. While he or she is working, pay close attention to how they install the filter and any other pertinent steps they perform. You can find out what it takes to do the task yourself and optimistically keep your unit functioning efficiently for a long time.
