When another company's technician told me I needed to spend $1000 to repair my unit and then recommended replacement, I contacted Diamond Air for a second opinion. Rance and Blaine evaluated my system and determined it could be repaired for less than $400. They were knowledgeable, professional, efficient and friendly. I am now a Diamond Air customer.

Chelsey took care of our scheduling needs and very prompt! Blaine took his time to explain our problem, what would happen and what needed to be done to fix it. I also really like how they will call you to let you know they're on the way. Every employee we have encountered is respectful with your property, they do not leave a mess and always wear shoe covers inside! I will continue to refer my friends and family to Diamond Air over and over.

Excellent service always. Respectful, knowledgeable and professional. Have dealt with Diamond Air for over 30 years, and wouldn’t choose any other company.
