Failure to change the air filter can damage other parts of the system and can result in a large repair bill later on. Changing air filters regularly can help preserve the life of your system and make it work more efficiently. If the air filter is clogged and can't keep contaminants out of the air as they should, those elements can return to the air you breathe. As a result, immediate problems could include itchy eyes or throat, headaches, and more.
If you continue with that same air filter and the problems keep pace, the long-term impacts could be serious. They include possible heart disease, respiratory disease, and even cause cancer, experts say. This results in much higher than normal utility bills. In fact, according to the Department of Energy, a clogged filter can cause a 15% increase in energy consumption.
You will no longer be able to filter the air properly, allowing dust and contaminants to enter the HVAC system. Personally, I always change my filters every 30 days and recommend the same to my customers: the EPA recommends at least inspecting their filter every month. Using an air filter with a MERV rating higher than recommended by the manufacturer of your oven or air conditioner may impair its performance. While it is possible to operate the system without a filter in the air conditioner, HVAC experts do not recommend it at all.
Over time, dirt can build up in the ducts, which means that a good amount of it will most likely enter your home directly and directly into the air you breathe. You can hear it: Your HVAC technician is giving you lessons on how to make sure you change your air filter. In general, filters with a MERV 16 rating or lower are considered HVAC system grade filters for residential, commercial, and general hospital use. If the air filter is dirty and you have problems with the air conditioner, most of the time it always returns to the clogged filter.
If I raise my hand to several ventilation grilles and feel weak or have a complete lack of air flow, the first thing that comes to mind is the oven filter. The accumulation of particles and contaminants connects to the filter and acts as a blanket that blocks the flow of air. In general, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days or 3 months. In addition to damaging your air conditioning system, neglecting AC filter changes can also cause mold to form on vent covers, ducts, and inside the air conditioning controller.
That layer of dirt and dust restricts the amount of air the air conditioner can “breathe”, meaning there is less cold air to cool the house.
