  • Diamond Hearing and Cooling. They are professional and follow through. As a contractor, it is important that the job is done correctly, passes inspections, done with craftsmanship, and the job site stays tidy. Diamond Heating and Cooling has met and exceeded my expectations on a number of jobs. Job well done.

  • Damien was very knowledgeable and professional regarding the Bosch air handler system. He communicated his findings very well so I could understand the problem and was proactive about what to do if I had a problem again with my AC. When he left after 1 1/2 hrs my system was cooling. I was given an appointment the same afternoon I called and given a 2 hr window that tech could show up. He was 15 minutes later than estimated, but the office called to notify and get my ok for later arrival. Price was fair for work performed. I would recommend Diamond Heating and Cooling Services to my friends and was very satisfied with their service.

  • Very prompt, thorough, caring, and honest professional service is exactly what you get when you hire Diamond Heating & Cooling! Our air conditioning system failed on a Sunday afternoon when the summer heat reached 91°. The next morning, I called Diamond Heating & Cooling, and they immediately sent a technician to diagnose and fix the problem. Since our system was the original unit from when our home was built in 2007, a full replacement was necessary. I was given three clear replacement options to choose from. Once I made my decision, their team came out the very next day. By 5:00 p.m., we had cool air flowing through our home again! I highly recommend Diamond Heating & Cooling to anyone in need of heating or cooling services. They truly care about their customers, and you can trust they’ll take great care of you too!

  • I was a potential client. I arrived at the office at 8:45am on a weekday, before they opened. The workers were outside waiting for the office staff. The workers were helpful and friendly. I spoke with the secretary on the workers phone. The secretary suggested that I leave my phone# with the workers. The secretary never returned my call.

  • Worker repeatedly refused to enter home because i have a cat

  • I could not be more pleased with the quality of service and general professionalism of the company. My Honeywell Truezone board fried during one of our recent power surges, so I called around to see who could install a new board. Several companies only wanted to install their board, which cost between $1300-1500 not including labor. I found a replacement board on Amazon for $400 and called Diamond about the possibility of installing it. They said yes immediately and came out and got my system running in less than an hour. I highly recommend them if you have any HVAC repair/service needs!

    Howard R.

  • I used to use them before but they have a person that is in the area of kernerville, Al and he is too afraid of my dogs as they were on the back porch 12 feet above ground and he left without completing the work. I decided not to use them anymore and got a refund . The owner gave me a hard time And I would not recommend this company .

    Mary W.

  • Amazing positive experience. I found this company through a professional aquaintance and can't say enough how impressed I am with their service. They go above and beyond and truly care about the customer. I signed up for their well priced VIP maintenance plan and trust that I am in good hands.

    Amanda M.

  • I want to take a moment to let everyone know how amazing this company is and their employees!! They are so professional and keep working until they find the problem. They continued to come back and fix the issues we were having g after having g a new unit installed. Never once with attitude or any amount of unprofessionalism. At that they even recorded and took pics of under the house of leaks we were having and informed the rental company for us!!!If you are looking for a HVAC company, I hands down 100 percent say go with these guys, they are great!!!

    Amanda M.

  • Great Job once again! Diamond HVAC came out and performed a service maintenance and inspection on my unit. The technician was extremely knowledgeable and professional and friendly. These guys are simply GOOD at what they do. I quickly signed up for their 3- carat diamond service maintenance agreement.
