Contractors often lament the fact that a customer who is already getting cool air is a hard sell for maintenance and service work. What these customers may not realize is that this “If it ain’t broke, don’t fix it” attitude can be expensive.
The performance of air conditioners is sensitive to service-related issues. Degradation faults, such as fouled heat exchangers, commonly make air conditioners run inefficiently and lead to premature equipment failure. However, if the unit provides cool air, the customer may not appreciate the need for service.
