I am a skilled professional that works for a Alaskan Air Conditioning & Heating - Tucson company. I recently completed a summer maintenance on a 2010 R22 Goodman split system. The maintenance included replacing the air filter, cleaning the evaporator coil, and checking the refrigerant pressure. I also checked the electrical connections and tested the system for proper operation. After completing the maintenance, I provided the customer with a detailed report of the work performed and made recommendations for future maintenance.
