A major piece of advice we like to give our clients about their air conditioning systems is to regularly change the air filter. This filter is sometimes called the “blower filter,” since it’s usually housed near where the blower pulls air into the HVAC system. Changing the filter is a part of regular maintenance for an air conditioner: it’s something our technicians do as part of air conditioning maintenance in Milford, DE, and it’s also a job homeowners need to take care of themselves during the rest of the season. We recommend changing this filter every 1 to 3 months, depending on the filter’s strength. Leaving it in place will lead to it clogging up, which severely affects AC performance and efficiency.
“So why bother with it at all?” you might ask. “Why not just run the AC without the filter?”
This isn’t a solution! The filter does an important job, and removing it entirely will lead to damage to the air conditioner, extra repairs, and likely an early replacement for the system. Below are some of the specific problems that running an AC without a filter can cause.
