I absolutely love this company. Not only were they amazing when they installed my new unit but then when my hoa had roofers on my roof and they messed up the unit they helped me solve that issue. I HIGHLY recommend everyone to use this company.

Michael M.

Outstanding service. Alfred & Cory are top professionals; they were on time, answered all my questions, didn’t leave any trash or debris like the last contractor. DIAMOND AC made replacing all 3 of my commercial unit super affordable and easy. Highest recommendation

Richard was excellent to work with. He took great pictures to show me where my problem areas were before starting work. My A/C unit needed cleaning and minor maintenance which he took care of quickly, then brought down pictures of what he had done. Looking forward to working with you again!
