5.0 Gordon Y. Surprise, AZ

Great service, great people great prices, Our air went out in middle of night, We had emergency complete system replacement that day. Never heard of such customer service. I give them 10 stars!!!

5.0 Brian Y. Peoria, AZ

When your air conditioner goes out you want it done fast in Arizona heat! Diamond AC & Heating proved to be everything we expected and more! A+ service in response, communication, quality AND price. They were great with going over our issues and what our options were. We have already recommended them to 4 others! We are definitely using the check up service in the future. I maintain my car so it works well for longer, now I understand how important it is to do it with my AC! Thanks for keeping us cool!

5.0 Mike G. Buckeye, AZ

I have used Diamond AC and Heating several times, from maintenance to repairs. Everybody there is courteous and professional. When I call, I feel like a person and not just a dollar sign. I try to get Richie but have had others that are great as well (David). They have actually saved me money. I thought that I needed a new system, they fixed my existing system, and let me know that I did not need a new system as of now. Very unheard of these days. I am a loyal dog in my doings and will use them always. Thanks for making me feel like a member of the family.

5.0 Rose C. Phoenix, AZ

Very friendly and treated you like familyð

5.0 Andrew S. Phoenix, AZ

We spent a week without AC working with American Home Shield to repair a 5 ton 4 yr old Carrier AC under a 10 year warranty. Without going into detail of the scam American Home Shield tried to pull on us, I called the AC manufacturer yesterday who recommended Diamond AC & Heating. Yesterday afternoon I called and talked with Cody. An hour later he was on my roof, diagnosed the problem, photo documented all that needed to be done and took the time to show and explain it to us. American Home Shield blatantly lied to me for a week and only would replace the compressor with a 2nd rate compressor and not fix other the underlying issues to make the system efficient and keep it from breaking down again! Cody and Andrew showed up this morning and our system is working BETTER than when it was installed!! Cody also included a 5 yr maintenance contract to inspect and clean the unit every 6 months. He genuinely cared about us and 8 rescue greyhounds!! There's an old saying "if you think hiring a professional is expensive, wait until an amateur gets their hands on you"! Thanks Cody & Andrew; blessings to you both and your families. Andy & Rob Robert Brunton

4.5 Michael M. Phoenix, AZ

Alfred & Cory are the next level option for AC unit replacement. I called several companies and Diamond AC was by far the best in communication, professional and on time! Their price was very fair , their service exceptional. I have already referred by aunt to them to replace her unit as well. thank you Alfred & Cory!!! Saved the day during this hot summer!

3.5 Ron G. Avondale, AZ

Install of a new AC/furnace was scheduled only 2 days after I accepted the quote. There were a couple non-critical follow up items to complete everything that took two more appointments, but everything was done to our satisfaction. The only issue was lack of communication on scheduling the follow up items and on giving me a call when they were on their way.

5.0 Janine C. Peoria, AZ

Everyone was great. All of the men were professional, respectful, and friendly. They were very efficient and got the job done quickly. They were clean and took great care of my property. I had to replace my 30 year old workhouse for a new unit. The new one installed by Diamond is awesome. From my experience, I would recommend this business to everyone who is in need of quality, integrity, and just good service.

4.5 Wayne L. Mesa, AZ

Very neat, respectful, punctual and explain what was done and what needs to be done, yes I do refer them to others.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
