What happens if you have a dirty air filter in house?

When the air filter is dirty, hot air is limited. This could cause the coil to freeze. As the coil thaws, water could begin to seep into your home and cause structural damage. A clogged or dirty air filter can spread contaminants such as dust, dirt, pollen, and pet dander instead of trapping them.

It can also restrict the airflow of the system, forcing it to work harder and consume more energy. Clogged air filters can make ducts dirty and leave a lot of extra dust throughout the house. Also be careful with dirt on the fan blades. A dirty filter won't be able to protect your HVAC system.

Dust and debris in a household air cleaner restrict airflow, forcing the oven to strain and use more energy to heat or cool your home. Just like replacing your car's engine oil and air filter every 3,000 miles, a clean HVAC air filter protects your heating system from being damaged and ultimately completely failing. This air filter exists between the intake air and the HVAC system. Therefore, a clogged air filter will prevent air from circulating through the ventilation grilles.

In other words, you won't have enough air to keep you cool (or warm, depending on the season). As a result, you'll feel less comfortable. The fact is that their forced air comfort systems are designed to absorb a certain amount of air every time they go through a cycle. According to the Diamond Certified Organization, a clogged oven air filter is the main cause of equipment failure.

Frost buildup on coils or fans makes it difficult for the air conditioning unit to remove heat from the air and cool your home. One of the purposes of an air filter is to filter out all microscopic particles such as dust, pollen, pet dander, bacteria, plant spores and mold, and even smoke. A dirty air filter can cause problems such as dirty ducts, poor indoor air quality, and unpleasant odors in your home. As the refrigerant evaporates inside the indoor condenser unit, the evaporator coil absorbs heat from the air blowing over that coil.

Not only will a dirty air filter cause an inefficient and improperly functioning air conditioner, it can also damage your oven. HVAC air filters work in partnership with your home's heating and cooling system to keep it running smoothly and efficiently. When the air filter is too clogged, the fan has to work a lot harder to try to get the right amount of air in. Lack of proper airflow causes this condensation to freeze, reducing the unit's ability to remove heat from the air (e.g., in a nutshell, every time the system is forced to work harder, it's costing you dearly (PLUS, you get less air for that money).

With reduced airflow, you may experience hot and cold spots in your home, and it can be difficult to achieve desired indoor temperature levels. Basically, an overloaded air blower can fail completely, causing the entire system to fail and costing you thousands of dollars for repair or replacement. If the filter becomes too clogged with dust, dander, and debris, then the blower has to work harder to get air through a clogged filter. We recommend checking your air filter at least once a month, but advanced filters can last a little longer.
