I am a highly skilled and experienced home service professional. I recently completed an annual preventative maintenance on an Amana ac system. This maintenance included cleaning the air filter, checking the refrigerant levels, inspecting the condenser coil, and testing the electrical components. I also replaced the air filter and checked the electrical connections to ensure they were secure. After completing the maintenance, I provided the customer with a detailed report of the findings and recommendations for future maintenance. The customer was very satisfied with the service and expressed that they would recommend my services to others.
