Does a Dirty Air Filter Make Your Furnace Stop Working?

Dirty air filters can be the cause of an inefficiently working oven. This is because the filters trap dust, dirt, and debris, such as hair, which can restrict or block vital air flow and prevent the oven from working properly. If the air filter is left in the boiler for too long, it can become so dirty that the unit stops working completely. It is recommended to change the filter every month. A clogged oven air filter will affect airflow throughout the house and the HVAC system.

The lack of fresh air in the oven will cause the heat exchanger to become too hot and deactivated. Dirty filters can also cause short cycling problems and make it difficult to maintain heat in your home. We suggest replacing the clogged air filter before the summer season to avoid damaging the air conditioner compressor. Over time, the air filter absorbs pet dander, dust, dirt, and other contaminants.

However, if the fibers become too clogged with debris, the HVAC system cannot draw air through the filter. This may cause the system to shut down. The fan performance of the heating and cooling system can have a major impact on your home's energy consumption. The harder this fan has to work to attract air to the entire house, the higher your energy bills will be. In fact, a clogged filter can consume 15% more energy, according to the Department of Energy.

This inefficiency increases rapidly as the filter becomes increasingly clogged or until it is repaired. Because not enough air passes through the coil, condensation normally dissipates within the furnace system. You can also see the accumulation of dust and dirt on the filter and make the decision to change it just because of its appearance. You should check the boiler filter once a month, especially during winter when it works hard to keep your home warm. One of the worst things about a dirty oven filter is that all of the dust and dirt that must be filtered is recirculated back into your home. Either way, oven filters must be changed periodically so that they can continue to perform their vital function and protect the oven while circulating clean air.

To find out when to change your filter, consider installing a CleanAlert FILTERSCAN WiFi air filter monitor. If an oven air filter is dirty or clogged, then more energy will be required for circulation fan to distribute air. Dust and dirt from a household air filter restrict air flow, forcing the boiler to work hard and use more energy to heat or cool your home. An oven filter serves as a barrier to trap dust and dirt that enters through return ducts so they don't reach the fan fan. If there is no filter providing such protection, then internal functioning of oven may become covered with dirt.

In severe cases, a dirty oven air filter can damage internal components of oven. So what's problem? Does an air filter really matter? To answer this question let's take a look at what happens if you don't routinely change your heating and cooling filter. The heat generated inside oven could cause extensive internal damage which is main cause of equipment failure.
