Best HVAC System Maintenance in Phoenix AZ

I thought Mike did an excellent job and handled our questions very well . I would highly recommend this company

I rarely write reviews but Cody and his team at Great State saved us when our ancient AC system died on us at the end of the summer. Within hours they had completely upgraded our extremely loud and inefficient 1970’s system and brought it up to code with a much safer and quieter unit. We have since noticed a significant drop in our monthly AC bill and our AC no longer sounds like a B-52 taking off when it starts up! Cody and his team went above and beyond in keeping our home clean as they worked and were incredibly friendly and professional. Highly recommend!

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.

I use their service several times, they are very professional & great prices

Paco is awesome professional HVAC technician. He is reliable, trustworthy and has fair service charges. He shows up on time and does his job. I have been using his services since last 3 years.

I would definitely recommend him to my family and friends.

Great a/c company. Professional. They really went above and beyond to assist me. Recommend to all.

RJ, my technician, was incredible! He checked my filter inside the house and also went above and beyond to make sure that EVERYTHING in my A/C was working correctly.
He was awesome. He was knowledgeable and friendly and he answered all my questions about my unit.
Custom Cooling is lucky to have such a great person working for them!

Good plumbers they always respond fast to emergencies even after hours

We had our annual a/c maintenance performed this week. We were very happy as always with the professionalism of our tech, Nicholas. He provided the normal photographic evidence of his inspection. Glad nothing was needed. Great company.

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

Not something that was normal.

I'm a very experienced tech of 35 years in commercial and industrial, highly varied venues. I'm nearly a year working for them now and have seen enough to develop a comparative opinion. Ontario appears to be doing a great job attracting talent similar to my own. As an experienced tech I have choices on where I work. The compensation is attractive, and the stress is low. I enjoy working with other experienced techs that talk the talk and walk the walk. There are around 160 techs working for Ontario. It's quite frankly a well run ship. It's no suprise to see ambiguous complaints. I get the sense other companies register us as a certain market threat. While I meet intelligent techs from other companies at parts houses too, clearly they must contend with us for a place at the top.

Muy mal servicio

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.

good service

My AC is leaking water into my home requiring extraction and causing damage. This company gave me an 8 hour window for the next day in which I was told I had to be available with a 15-30 minute window from 8-4 pm. Was told if I missed the call or didn't answer, they would boot me to the next day. So, I canceled my whole day for their supposed availability. At 1 pm, I called and was told that they canceled yesterday and did not let me know. Would NEVER use such a company - EVER! If your Home Warranty suggests them, you need a back up plan or refuse to allow them to come.
