"Probably one of the best customer experiences I’ve ever had with an HVAC company. I’d recommend them 10 times out of 10 without a doubt!"

Avoid Breakdowns

An air conditioner, heat pump, or ductless system that receives regular attention from a NATE-certified tech (like those here at Trahan’s!) is far less likely to break down in the summer.

Take the best step toward avoiding the hassle of an AC breakdown. Call Dufrene’s to schedule an AC tune-up.
