What does an A/C preventative maintenance check include?
During an A/C PM, a tech may check:
• Overall system operation
• Temperature drop across the system
• Air filter condition
• Indoor coil and blower components
• Outdoor unit condition
• Electrical connections and components
• Capacitor and contactor performance
• Condensate drain and visible signs of wear
The goal is simple: catch small issues early, improve efficiency, and help prevent avoidable breakdowns when Michigan heat and humidity kick in.
