Diamond Air exceeded every expectation. We reached out after noticing our heating system wasn’t performing well—and with kids in the house, comfort is a big deal for us. From the very first interaction, the team was responsive, professional, and incredibly knowledgeable.

Very professional and friendly. Diamond Air services takes their job seriously. From putting down floor protectors to wearing shoe covers. They were priced competitively, kind, and do quality work. They installed a mini-split, hiding all lines, and gave us a fair price. They communicated with us throughout the process and even reviewed how to use the AC after they were finished. To top it off, they put a "Cookie Monster" sticker on the unit since my wife's nickname is the CookieMonster. A great representation of their customer service and attention to detail. Would highly recommend them to anyone.
They were able to get me scheduled for an appointment really quickly. Their phone operators are very friendly and helpful and they maintain good communication before the appointment to let you know which technician is coming and exactly when. Howie and Mac were the ones who assessed and serviced my A/C unit and they were both very thorough and took the time to explain everything really well. I would absolutely recommend!
