Entire experience was OUTSTANDING! I got quotes from three different companies and Anthony from Diamond Air was the best for equipment options and price. The installation crew (Aldo, Oscar, Will & Carl), were professional, and courteous, while providing quality craftmanship services. They kept me informed on the status of their work. Completed work within the promised time schedule. Upon completion work area was clean.
THANK YOU, DIAMOND AIR.

Received a quote from Anthony for a full AC and furnace change. He was very polite and explained to us everything that needed done. A very detailed quote was sent. Not the cheapest but not the most expensive. Job was done by the beginning of next week. Crew was very polite. Only issue was cleaning after the project. There was some messed left. Anthony came and did a final walkthrough and easily fixed the next day! Installation, HERS and city inspection all done within the week. Awesome customer service!! Highly recommend!

I recently had Diamond Air out for maintenance on my HVAC. I was very impressed with their customer service. They were able to get me an appointment quickly and the technician arrived on time. Mac Apocada was very professional, attentive and friendly. He took the time to explain in detail his process and I feel much more educated now about HVAC units and Nest thermostats. Mac provided excellent service and I will definitely hire Diamond Air again for all my future needs.
