Testimonials

“I had Ray install a whole new furnace a/c and all new duct work in my remodel project. His craftsmanship was superb and his price was very reasonable! I watched him build a custom duct for the project in the field that looked like it was built in the shop. I will definitely use him and Westenn on my next project. I highly recommend Ray and the Westenn company. ”
Tommy G • Remodel Design and Install
“The technician you sent was outstanding! I don’t think I’d rate any other HVAC tech higher that I’ve ever used – sharp – quickly diagnosed the issue and fixed it.”
Mike C • Residential Repair
“Thanks so much for a positive experience and a great group of people to facilitate our A/C removal & installation.  I will be recommending you to other friends & family”
