You can have your Air Conditioner run at a lower cost if you keep up to date on maintenance. Yes, it is very important to change filters regularly. How often?  Standard filters should be changed monthly during the cooling season. The next issue is a Florida thing, drainline algae. Drain line clogs are the most common service call we get. Wet/dry vacuuming your drain line monthly can also avoid a service call and system downtime.
