How do I maintain my air conditioning unit?

Clean or replace the filter every one to three months during cooling season. Clear debris and vegetation at least two feet around outdoor units. Clean the condenser coils annually. Check the condensate drain line for clogs. Have a professional service the system each spring to check refrigerant levels and electrical connections.

Why It Matters

Regular AC maintenance improves efficiency, lowers energy bills, and prevents breakdowns on the hottest days.
