We just had Anthony and his crew replace our air conditioner and furnace. We have been rebuilding our home for the last two years basically from the ground up and have had every kind of contractor and servicemen come through for various projects. Diamond air services were the most common sense, reasonable, easy to work with, professional and knowledgeable crew we've worked with. Honest and prompt communication. Can't say enough about this company. I'll be referring everyone I can to them. Howie , Mike and Anthony- and your guys are doing an awesome job.

I investigated many companies for replacement of my forced air heating. After reading reviews from locals, I decided on Diamond Air. They were professional, on-time and contacted me with all information regarding my upcoming service. Today four people arrived and my new system is installed and done well. An existing item I had was not to their liking so they made a trip to the hardware store and replaced it without a charge. My system was checked and running before they left. I am very, very happy. Thank you Diamond Air for your professionalism and what I considered a great price.

As a Contractor for 25 years, I hired Diamond Air to replace my 4 Lennox HVAC units . I put them under pressure to perform quickly as my custom post modern hi tech home was to host Apple TV for a 10 day photoshoot/TV episode. I requested 3 5 ton Lennox SEER package units and a 5 ton Lennox split system along with space age air scrubber tech and NEST controllers along with total return and supply vent cleaning of of 40 areas. Diamond Air was professionally equipped, courteous, value priced and prompt. This company beat out bids from WeCare, Nexgen, and some smaller quality subs.

I have been a customer of diamond air services for 2 years now and they just keep on continuing to impress me with there excellent service I called them out for my elderly parents furnace problems being elderly they can't be without heat especially in the winter I called Howie at diamond air he sent Mac out the next morning he did his troubleshooting and that young man did not stop till he fixed all my parents furnace issues a different company would of said well your furnace is very old why not replace it my parents are on a set income and Mac new that he told me that if would of through in the towel and have up he wouldn't be able to sleep at night and to me that is pretty impressive believe me I know cause I've been through a lot of company's before I found diamond air there is no other company out there that tops this company call them if you want a honest company

I used this company today to address my home a/c repair needs. The technician showed up on time and did the service excellently. He was extremely professional, knew his stuff well, and was upfront about the pricing. He answered all of my questions and shared various information regarding my unit. Thank you very much!

They will be my first call the next time I need hvac repairs.

Positive Plumbing Heating and Air, is a true testament to the American dream. The immigrant/family-owned company is led by the owner, Alex, who is originally from Africa. He was born and raised in Rwanda. In 1994, he escaped the country during its genocide and spent over seven years in refugee camps in several neighboring countries until he finally got an opportunity to come to the United States: “The place where freedom lives and dreams come true.” He is grateful to be an American citizen and is happily married with two young children. He and his family have lots of love for others, especially those who are in need and have no food. To give back, Alex and his family love to help poor families in Africa by providing life’s necessities to those people in need. It is because of his background that Alex takes pride in providing the best service he can for those in Orange County with plumbing, heating, and air conditioning needs at a fair and modest price.
