Customer Testimonials

“Seth was our salesperson. He listened to our needs and provided the right product at the right price. The installation team arrived on time and went right to work.They worked with confidence and professionalism.We appreciated the care in protecting our floors and even the choice of how they went up on the roof indicated that they really did care. This company did what they said they would and certainly has our vote of appreciation and gratitude. We will happily recommend Design Aire to anyone.”
Ken L.

“One of the best companies to work with. My own profession is in a service industry and so I very much appreciate all the positive things about Design Aire.
The install crew arrived right on time and took exactly how much time they said they would to complete the job. The work was done well, the crew cleaned up after themselves, and were very pleasant. Seth in the office was extremely in-tune to our needs and very responsive.
I would highly recommend Design Aire.”
Heather H.

“I was very impressed with Design Aire. They were timely and did an outstanding job with the installation of my new furnace. They had great communication and went above and beyond. I would highly recommend them to friends and family. Thank you so much Seth and Design Aire for making this an effortless transaction. VERY PLEASED!”
Jonny M.

“Design Aire sent a salesman to plan the system, and just a couple of days later sent the installers to remove the old system and install the new one. Everything happened when they said it would and the system performs as they said it would. All of the Design Aire staff were courteous, the work was performed efficiently and neatly, and they left the area cleaner than they found it. This is the second unit Design Aire has installed for us, and I have no need to look elsewhere.”
