Great company! So happy they had a same day availability that didn’t cost us and arm and a leg! Mac was a great and friendly tech! Felt like a friend was coming to help us out! 10/10 would call again and recommend to friends and family! Service: HVAC system maintenance
My A/C unit went out and Anthony was able to get a tech out in 4-5 hrs. Mac was our service tech. He was on time, professional and knowledgeable. He walked me through everything that he was going to do to fix the issue on both units. Extremely honest, clean and got the job done fast and A/C was running in a few hours. My appointment time was from 1:30-2:30. I received a call from Anthony the owner just to let me know that Mac might be a few minutes behind but he showed up in my hour window. Communication was something you typically do not get these days. Diamond Air will be my first call if I am in need for a service.
My HVAC unit is pretty old and wasn’t really functioning properly, 30+ years old and so I needed an honest opinion if it was time to upgrade. Called up Diamond Air services to check it out and spoke to Anthony to set up a schedule, Joey showed up and diagnosed the whole unit and gave me an intelligent honest opinion. We decided to upgrade and Anthony gave me a thorough breakdown on how the process goes. Scheduled the week after for install and would take 2 days. On the day of install the crew showed up, Bobby, Mike, I believe (Sean and Carl? And another person) I’m sorry if I didn’t remember the names correctly. They were courteous, efficient, and fast. One crew worked outside on the AC and another in the attic for the heater/duct work. They were done on time and did an awesome job. The AC was finally blowing nice cool air all over the house, It felt great. There was a slight issue with the heater fuse and primary drain being clogged, so they rescheduled to come back and fix it.
