Best Mechanical Systems in Phoenix AZ

came within 24 hours and had the critical part in the truck!

Eric Smith was prompt and curtious and did a thorough job of inspecting everything listening to what I had already discovered prior to the visit. I appreciated him respecting my small knowledge compared to his life. His demeanor was very non-threatening, and I felt safe within my home while he was here.

Was referred to 1st Choice by Home Warranty and was scheduled and visited the next day. A part needed to be ordered, but Mike got us up and running so we wouldn't have to be without cooling until the part came in. Great service, would highly recommend!

This company is the best we have ever worked with. They were here and completed the job in record time. We highly recommend them, and could not have asked for nicer people to work with. They did everything they said and more. They are a five star company. Thank you so much.

Came right away and did the job so well. I really like this company.

A new a/c was installed today. So far so good. Sam, the general manager, is very professional, experienced and meticulous. Still too early to evaluate the a/c itself though.

The plenum fans this company manufactures are superb in several respects. All the bathrooms in my house have a Baikal Mechanical exhaust fan now. I no longer worry about air circulation issues, poor air quality, mold growth, etc. because of these fans. What a great buy!

Larvell was incredible. Excellent contact that began prior to the appointment and continued during it. He was attentive to our requirements and collaborated with us to find a solution. It was an amazing experience. Couldn’t ask for a better air conditioning team!!!

By far the best Mechanical Contractor in the State!

Jeremy and his team have been our GO TO for the last few years. When we had issues with ac he recommended our new system and we found his suggestions were cost effective and his followup maintenance has been excellent and not costly.

Great group of guys and excellent customer service! Quality and consistency of work was so stellar that that I decided to work for them myself after being a customer for 3 years.

We have used alliance for multiple sites for multi housing office workers that answers phones are rude and feels like Inconvenience when I call their field manager or supervisor Ryan it’s very unprofessional with their bids and unorganized I work with a lot of Plumbing and Hvac companies but this By far is the worst one I had to deal with

I sit near it, but don't know anything about it. Guess they keep Sky Harbor cool/warm.

Ive had a lot of issues with this company... but the one I cant get passed is.. they didnt set up the common wire to my Nest tstat.. just so when the battery died they could get another dollar charging me for that fix. I fixed it myself.. and found shady HVAC companies do this to scam costumers.

My nest thermostat wasn’t charging so I was charging it manually. We asked for them to install a common wire from AC unit to thermostat so it could self charge.

They came out and said they found an “extra wire” and connected it. They said to charge my thermostat and put it back on in a few hours to see if the best holds charge.

So I plug it in and the nest pops up a diagram I’ve never seen before stating there in no power to my AC unit at all. So my AC unit was working, they came out and now it’s not working. I get a call back after asking for a recall from some guy who genuinely didn’t care. He tried to question whether this was his guys fault multiple times. Questioning the timeline. And then demanding I pay an extra 150$ just for them to come look at it today.

Look, this was clearly their fault. The unit ran fine, they came out and now it has no power. Pretty freaking simple timeline. I just want this fixed. I have 5 children under the age of 10 and it was 45 degrees in my house last night. Most of our belongings are in storage as we are set to a move in 48 hours. I need them to do the right thing. I need them to fix their mistake.
