Reviews of local pros in Irwindale, California

Greta service, had a residential HVAC system inspected and diagnosed - found nothing. Also received air filters as part of the service.

I had an A/C problem and needed a reliable service. Diamond Air Services caught my attention with their high rating, so I contacted them. They arrived promptly and quickly identified the issue - very efficient and courteous. Pricing was fair, making them my top choice for air conditioning services.

Diamond delivered when I needed them most - total HVAC replacement was a top priority. After getting quotes from three companies, their offer stood out. Initially, I was hesitant about choosing the lowest bidder, but Anthony's guidance made me feel more confident in my decision. The crew that arrived on site were consummate professionals and courteous, with Bobby and Mike standing out for their exceptional work ethic. I'd be lying if I said it was easy working with me - I can be a handful sometimes - but they adapted quickly and got the job done to my satisfaction.

We're extremely grateful to Anthony, Bobby, and Jose for their outstanding service. After a massive construction project, they stepped up as our go-to HVAC pros and far exceeded our expectations. Anthony kept us informed every step of the way, handling everything with professionalism. When we discovered issues after taking possession, Bobby and Jose went above and beyond to resolve them, even when things got tricky. Thanks to their expertise, we wouldn't be struggling in the sweltering heat this summer. Their dedication is truly appreciable.

Impressive service from start to finish. Scheduling was effortless, and Oscar arrived promptly to explain his plan of action. He was incredibly professional and courteous throughout the process. His diagnostic tests quickly identified the issue, which he efficiently resolved by replacing the capacitor within 30 minutes. Payment processing was seamless. Overall, a hassle-free experience that left me extremely satisfied – I would highly recommend this service to anyone.

Before finishing, they walked us through the maintenance process, explaining what we need to do to keep our new unit in good shape. When comparing quotes from other companies, Diamond Air stood out with a fair price, including all necessary components and warranty terms. We wholeheartedly endorse Diamond Air for any AC-related work.
