If your home has an HVAC system, a dirty air filter can be the culprit behind your air conditioner not cooling. When dirt and dust accumulate on the filter, it restricts airflow, resulting in hot and cold spots throughout the house. Not only does this cause discomfort, but it also leads to higher energy bills as the air conditioner has to work harder to push air through the clogged filter. It's important to check your air filter at least once a month, especially during times with high pollen counts or excessive dust.
If you notice that the back of the unit is too hot, it's a sign that the filter needs to be replaced. An overheated air conditioner is a result of the blower having to work harder when the filter is dirty. If you leave the air filter of an air conditioning unit clogged for too long, you may experience a system-wide failure. The filter in an air conditioning unit is an incredibly important part that cleans the air that goes into it.
The air conditioner's ability to expel heat from the air inside your home will decrease when the evaporator freezes. A dirty air conditioning filter can wreak havoc on your HVAC system and lead to costly repairs or a complete breakdown when you need your air conditioner most. Fortunately, there are many ways to keep your air conditioner well-maintained and running efficiently for longer. Don't let a dirty air conditioner filter stop you from feeling comfortable in your own home or lead to costly repairs.
Change your filter every one to three months on average, but check it monthly during times with high pollen counts or excessive dust.
