Best Attic Inspection in Phoenix AZ

I made a great decision with Larson Air Conditioning. From the very beginning, they were awesome. I received a call the next day after submitting my online quote request. When Jacob arrived, he was very considerate. He was extremely detailed and answered all my questions...which were a lot.
The day of the installation went smoothly! Mike H. and Ryan were great. They worked well together to ensure my unit was properly installed. My unit was originally from the late 80s, and I had a mecury thermostat.
The guys did a great job all around. Mike was extremely patient with the Nest Thermostat installation. It was extremely difficult, but he worked with me to figure it out. I am definitely looking forward to the summer with my new AC.

Chris was very professional and cleaned up after he was done. He brought plastic to cover the clothes in the closet, wore shoe covers when in the house, and vacuumed up after he was done. He explained what was wrong, how he fixed it, and prevention. I needed my primary drain cleaned out and had a secondary shut off switch installed. They are a local small business that I would support again! Thank you :)

We had our 6 month service today performed by technician Nixa . She was outstanding . She was thorough , shared photos of her work and explained what she did today . She is the best tech we have ever had from any company . We are impressed with her and the quality of product and service from Desert Diamond mechanical .

Excellent and trustworthy service. I will definitely be using this company for all my air conditioning needs. Highly recommend giving them a try.

Super Easy to work with. Quality painters. My house is beautiful again!  I had them paint the exterior of my home. It was built in 1996 and had never been painted, so there were many stucco cracks and my patio celing was peeling and cracking something fierce. They were fast efficient and truly did some quality work. I totally fell in love with my home again.
