HVAC reviews in Mesa, Arizona

The staff at John’s were very helpful in setting up prompt appointments. My work involved installation of a new water softener system and a kitchen sink food disposal unit. Technician Mikel Guerrero was super helpful in pointing out the options and helping to pick out one at a reasonable cost, as well as efficiently getting the job done. I would like to specially commend his polite and professional approach throughout. This is my first experience with John’s Heating Cooling and Plumbing, and I came away with a very favorable impression.

Derek was very informative and explained the features and functionality of the new system.

He also ensured everything was tested and was satisfactory during the install. Highly recommend the recirculating pump to pull the hot water immediately through the lines at the furthest point of the house.

A pleasure doing business with him!

I can no longer recommend John’s. They have done right by me in the past but my most recent experience leaves me feeling I can’t trust them.

- I scheduled routine maintenance and they canceled the appointment the morning of - okay whatever, things happen. It was three weeks until availability lined up again which was inconvenient, but not the end of the world.

- When the technician showed up my wife texted me at work with concerns about the technicians physical size and fitness to work on our roof. I reassured her that he was there with John’s, we liked John’s, they have been great in the past, he is their employee, they’re insured, I’m sure he’s a professional and it’ll be fine.

- After looking over the units the tech has recommendations. Of course he does, you’ve got to sell the product, but our units are new. John’s installed one of them July 2023 and the other June 2024 and they don’t need anything. He’s really pushing a coil cleaning, selling it up like if we don’t drop $500 for him to empty a can of cleaner we’re going to have a catastrophic failure any day. I declined, he seemed kind of salty, and apparently after getting off the phone he was hard selling my wife to go around me and agree to the fluff job anyway. Not cool.

- He said the newer unit had a failing capacitor that he would change out under warranty. Again, it’s a new unit, never had a problem with it, but if he put a meter on it and it was failing it’s surely a good idea to replace it proactively. (Although judging from the rest of the encounter I’m skeptical that he owns or knows how to use a meter, and just wanted to pad the bill with some labor somewhere.) He went back on the roof and left a while later without checking back in, sat in his truck for about 30 minutes, and left.

- Three hours later I get an email from my thermostat stating that my newer unit has been in cooling mode for four hours and the indoor temperature has risen by 6 degrees. The guy couldn’t even be bothered to verify the unit ran before he left.

- My wife called John’s and asked them to return and make it right and the receptionist said “we’re busy, we’ll try to get there in the morning.”

- I was in shock and called the receptionist and explained this just wasn’t acceptable, we had working AC before their tech screwed it up, do the right thing here. Nope, they have other customers, they’ll get there when they get there. No urgency, no apology, no concern for their reputation. Three day disruption for simple scheduled maintenance (cancellation + botched job + fixing their own error)

- When I got home from work the unit was humming away with the nasty 60 cycle hum of alternating current burning the windings on a stalled out electrical motor. You might recognize it as the sound your unit makes when the start capacitor has failed and can’t start, so you pay a few hundred dollars to replace it and six months or a year later the compressor fails.

- The next day the same incompetent tech shows up. His explanation was that “a wire must have come loose.”

- This morning I noticed my rain gutter is smashed to hell where an enormous technician leaned an extension ladder against it and decided to get up on my own roof (with a step ladder) and just look at the units. There were extra screws on the roof around both units, missing screws on the units themselves, and cold air leaking from open probe holes on both sides of both elbows that the tech couldn’t be bothered to put a little tape over. Rather than deal with this same dopey tech I took three minutes to grab a nut driver and a few inches of foil tape and just cleaned up after him myself.

Unprofessional all the way around. This is my home, and I’ll be on the hook to repair whatever else this incompetent fool screwed up while he was in there and I really don’t appreciate that John’s has subjected me to that kind of liability.

My Technician was Alex, who was friendly, competent, careful, and knowledgeable. John's was a pleasure to do business with from the office to my tech. I recommend them.

Excellent and prompt service from Derek. This business is a pleasure to work with and I give it my highest recommendation.

The error code on the tankless heater was diagnosed and repaired - along with preventative maintenance. My overall experience was so positive that I signed up for their annual maintenance plan.

Great company with an excellent team of people. Calling and scheduling with Taylor was quick and hassle free and Tremayne, my technician, was professional and really personable. This will be my go to company for any of my AC needs!

Caleb and Marvin were excellent! They installed a whole house filter system and new Rinnai tankless heater, and they work great

Very good experience today with Alex. Polite, thorough, explained everything, honest, tidy, communicated well. He checked my air conditioner/furnace. Cleaned exterior unit and replaced a part that was showing wear. Suggested options that will prolong life of unit but without urgency and with integrity. Will use this company going forward.

My repair man was very polite, explained what needed to be done to get my system( heating and air conditioning) up and running again. Showed me pictures of what needed to be replaced and did this in a timely manner. I was very happy with how he handled himself throughout my whole process from start to finish. I would certainly deal with JOHN’S COMPANY again.

Michael is very knowledgeable and personable. He's a very good listener and he really wants to help. We received a lot of good advice. He and his team, who were all very nice, did a Hydro Clean at our house. The before and after pictures are amazing! Our pipes are sparkling clean. I would highly recommend this company.

The whole team today was awesome! They came early and worked until our big project was done even with crazy heat today. We had 3 a/c units replaced, and John's didn't disappoint! We have used John's for years and still highly recommend.

Brad was very kind and professional. He came out to check our AC unit in our home and the one we have in our shop. He offered options we came to a decision together and everything turned out great. He’s a wonderful young man. You’re lucky to have him work for your company.

Tech Michael was wonderful. They had installed a shower faucet about a year ago and handle was coming loose. He showed me how to fix it, should it happen again. Then we were talking about how cold the water is that comes out of our kitchen faucet in the morning during winter and he recommended a relay from the hot water heater that would get us hot water at the tap within 30 seconds. Such a game changer. Use to turn on faucet and walk away for a couple minutes before it would get hot. Now it is almost instant.

First of all, I’ve always (several years now) had good experiences with John’s. They’re always responsive, professional, and diligent. I like that there’s no intentional confusion. They essentially say “here are pictures, here are OEM recommendations, here is where you are supposed to be, and here is where you are at” then proceed to explain things so you understand. Tremayne visited me today and upheld my opinion of John’s. He was nice, professional, and gave me several options that were clear cut. I appreciate that. I signed up for another 3 years of maintenance! John’s will be my AC company for the foreseeable future.

Absolutely the best plumber I ever had. He noticed and fixed the problems no one else could solve. For 20 years other plumbers never could find which way my pipes were going. Seriously. They thought my pipes were going in the opposite direction from where they were actually going. Sounds unbelievable but it is sadly true. Steven had it figured out in less than 20 minutes. Wow is all I can say? Plus I got the most professional service you could imagine. That kind of service is almost to good to expect. I would never go anywhere but John's plumbing. Give Ashley a call for all your plumbing needs. You will truly be amazed at the quality of service you get! Marlin in Mesa.

Mike was very pleasant putting up with our yapping puppy. He gave us range of repair options and set us up with temporary service until replacement parts arrive. Quite pleased with the whole experience.

Our experience with John's was nothing short of incredible. Shawn did an awesome job asking the right questions and evaluating our home to get us into the right HVAC unit for us. Justin and his team made the install look easy! No AC in the summer is a nightmare, but John's was able to come out same day to review our home and the new AC was installed less than 48hrs later. Great communication, timely service, and transparent selling. Can't recommend them enough!

Great experience with Victor who came in & tried his best to figure out the issue with my AC unit in this Arizona heat. He then help provide me with all his diagnosis & then told me what needed to be done. Really appreciative of Victor.

Ken is a super star! Cannot be more grateful to this company’s quick professional response. After 9 days without air conditioning thanks to my home warranty i finally have air. In addition to repairing the blower they thoroughly repaired the damage done by the contractor sent by warranty company. Use Ken for ALL your air conditioning needs, he will not disappoint. He got the job done so quickly. Cannot give 10 stars but I totally would!! Thank you!!

Robert gave us a 30 heads up he was on his way. He arrived on time, checked our AC units and attic HVAC. Robert was awesome, spent the time to explain everything, made sure we understood what was going on with the units and said to contact him if we had any other questions or concerns. Robert was great!!!

Chris did a great job explaining the status of my current unit and discussing my options. he was very polite and knowledgeable. Thank you Chris!
