Repair, maintain, or replace?
Repair fits when
The issue is isolated, the system is otherwise keeping up, and you want the fastest path back to comfort.
Replacement fits when
The system is aging, repair costs are stacking up, comfort is uneven, or you want lower bills and better reliability.
Maintenance fits when
Everything works, but you'd rather catch the small stuff now than gamble on a breakdown in the next heat wave.
