How Often Should I Change My Air Filter?

Are you aware that both your air conditioner and heater have air filters in them? Most forced air climate control systems do, and for the same reason: to protect them from dust and debris that may blow in from the ducts. The air filter captures any detritus that may be blown in from the ducts, while allowing air to pass through and into the system. If the filter isn’t changed often enough, though, it can cause a range of problems.


The single biggest problem that can affect an air filter directly is clogs. The filter is very good at collecting debris of various kinds, but unfortunately it has no way of actually ridding itself of the things that it collects. If the filter isn’t cleaned out every 3 to 4 months, it will be in danger of becoming clogged. A clogged air filter will cut off the flow of air into the climate control system, leading to an increasing number of problems.

In heaters, especially, a clogged air filter can pose a threat to the well-being of the entire system. Cutting off the flow of cool air into the system causes the heater to start overheating, which will force it to shut down as an emergency measure. After a while, the system will turn on and attempt to heat again. Without fixing the clogged air filter, though, the system will simply overheat and shut down again. This is called short cycling, and it can cause all kinds of serious malfunctions for heaters. It can also substantially shorten the lifespan of the heater in general, so it’s best to avoid this problem altogether by getting your air filters changed.
