Best Home Seal Services in Phoenix AZ

I've been doing business with Desert Diamond for nearly 20 years, when it was just Carlo doing it all. They are very professional and I've never had any issues with them trying to upsell me on something not critically needed. I just had my semi-annual PM service and the tech was Cody. All of the techs are great but I am always impressed with Cody, he goes above and beyond and takes the time to explain what he saw and shows me pictures to back up what he says. He is friendly, personable, and knowledgeable. With employees like Cody on staff I will continue to do business with Desert Diamond.

I called the company and spoke with Jesus. Regarding my central air wasn't working & he came 30mins later to fix my air system. I really appreciate the fast service now I have air something you need living here in AZ. Thanks again Jesus!!!

Troy moody was our plumber from Day and Night, and he did an outstanding job. Our water heater had been having issues and Troy was able to identify the multiple issues and quickly fix them. It was nice to have someone with clear knowledge and experience on the job. Would recommend.

Bonz is the man! Upfront and professional. You'll be impressed, ask for him.

These guys are great! I talked with one of those big name companies first. Then I talked to Chris over at Alien. He explained that it would be about 3x LESS than what the big companies were charging. He never tried to upsell me (which is a big deal to me)... in fact, he explained that I actually needed to downsize for better efficiency. Jeremy and Mike were professional and thorough. Everyone explained every bit of what they were installing and what they were doing. And when my Nest thermostat was giving me issues not long after the install, Chris came by the same day to take a look at the wiring.... He fixed it in minutes! (it was an improper install from the Nest people) I love my new AC unit! It's working GREAT! And it's nice to know I have some knowledgeable and trustworthy people to lean on when I need help!

Clifford is Great! He is knoledgeable, efficient
and patient with a non-techie.

George Brazil Michelle was my technician she was very knowledgeable clean and performed everything required. Due to my disability she was helpful considerate and we had a great conversation. I would give her an A+ on a grading scale I would recommend her to anyone. As it turned out you remember the favor I did her 10 years ago how ironic pay it forward.

George and his staff are amazing! My tenant told me on Tuesday that the heat wasn’t working, the technician was at the property within 2 hours of calling. The HVAC was 24 years old, so I had George give me quote for a new system. On Thursday he installed the new split system HVAC, 2 days from service call to install, the price was less than the other quote that I got and his detail and workmanship is top notch. I have a few rental properties on preventative maintenance plans with him. I would highly recommend George and his team for HVAC maintenance, repair and install!

I Highly recommend Preferred Air. I would like to compliment Fernando, Daniel and Bobby on their diligence, expertise and honesty. The receptionist was super nice.The whole team is awesome! Totally satisfied.

We had a great experience with Jonathan. Would use again! Highly recommend

I've used Howard Air for several years. Recommend asking for David as your HVACC tech. He is excellent!

These guys are fantastic workers will come quickly when you are having problems. Gerald came to my house at 9:30 pm in the middle of summer to fix a thermostat that had frozen over. Talk about customer service, God bless him! They're efficient and reasonably priced. I highly recommend AirZona for your HVAC issues.

New post: AirZona installed a split A/C unit for my man cave, a transformed garage. Living in Phoenix, I wanted to get this done before the oppressive heat of summer. I ordered the unit on Monday and Gerald’s guys put it in the very next day, Outstanding service, very affordable and really nice guys. I highly recommend AirZona.

Very professional, listen and answer our questions

ACA responded to my call the same day. The next day the salesman visited and the new unit was ordered. The market is tight but ACA came through!

I recommend Green ID if you ever need a home energy audit or any energy upgrades. They recently completed an audit of my 60+ year old home, which had significant room for improvement. Within a couple weeks, their team upgraded my attic insulation, duct sealing, and air sealing. I found their proposal very competitive and they are reasonable on pricing. David, the owner, was very accountable and quick to respond to any questions or concerns that came up. He even came out on a Saturday in order to address an issue that came up after initial work was completed the day before, and fixed the issue on his own. His team even came back up to re-blow the insulation after he had stepped through the attic, triple check everything, and add finishing touches. It is inevitable that issues may come up any time house work is being done, but what is important is how the company resolves them. Green ID demonstrated a high level of integrity and expediency in resolving and I feel good about the work they've done. Green ID has done a lot for me and I look forward to lower heating and cooling bills this upcoming year!

Reviewed furnace & found it to be in good operating condition. I am pleased with your company’s work.

If you need A/C pros, these are the folks to deal with!

Highly recommend! Dave and his associate were on time, extremely knowledgeable and helpful. Great price for HVAC checks & maintenance.

Very friendly. Did good

We called late last night because our AC system broke. While other companies advertise themselves as “24 hour emergency repair” they were the only ones who were willing and able to show up and do the work. Casey was at my house within the hour and fixed the system as well as explained the problem and what he did/how he did it as well as tips on how to keep it from happening again. 5/5 would recommend and we will definitely call them again should we need their services
