In South West Florida your basic filter will need to be changed or cleaned every month especially during peak seasons.
It is important to keep your filter clean. With out a clean filter you are blocking the air flow to your system and making it work harder. The harder the system works the more money it costs you. When filters get packed in with the dirt, dust and debris your coil will freeze up and stop cooling your home. More service calls can be avoided by keeping that filter clean….and save some money.
