Best Heating & Air Conditioning/HVAC in United States

These guys are great!  No hassle.  Low charge for service calls - I forget if it is $40 or $60, but either way, it's a good deal for an honest diagnosis.

Nothing but quality service and advice from Chad,who along with his wife Nicole,own Paragon Service Pros. Currently have a service contact with Paragon,that is not only a good value and piece of mind but also offers some discounts as well. Recently had him and his team perform a HVAC duct cleaning,along with the clothes dryer duct cleaning,on our home. A nice difference in the air quality in our house. On time arrival,professional appearance and timely competition of service round out our experience with Chad at Paragon Service Pros.

Contacted Aire Serv to do an evaluation of the AC unit prior to selling the house. The tech was friendly, on time, and very thorough in his work.
The reason for 3 stars is simple. The tech determined in the written report that the AC unit needed replacement but would not provide a quote. The best he could do is give me a range of 5-10k for the replacement. I was told that they don't give unit replacement quotes to consumers that shop competitors. This statement is puzzling to me since I wasn't shopping competitors at that time. Besides, we live in a democracy where markets heavily depend on competition. Simple economics! Long story short, I ended up replacing the unit with another company two weeks later.

We have been using this company over 5 years now. Very professional, knowledgeable, trustworthy employees who show up on time. We'll be using them in the future. Thank you

I just have to say that I am happy with the service. Benny was here and got right to work.  I needed to switch out a ceiling fan.  I chose this company because it's local and open 24/7. So I thought what the heck let's give them a try. When I called he was really nice and helpful. He didn't try to nickel and dime me. He said he can make it within the hour. Now that's what I call service.  Benny also services ac so if you are looking for ac service I would highly recommend his company.  I feel he know what he is talking about he has been in business for 20 years. I definitely know who I will be calling when that time comes.

Trae and Mark did a fantastic job replacing our 4 ton unit located on our roof.  They were prompt and professional.  Mark set the expectation and both he and Trae more than delivered.  On top of that, their prices were very competetive!!  We HIGHLY recommend Top Tier to anyone in the market for a new AC/heat pump.

Arrived on time!  Completed a quick diagnosis of the issue. Replaced a corroded refridgerator waterline. Repair completed in under an hour. We will use again this company again.

They came out to diagnose my unit problems. The gave me an estimate for a new coil, pan and drain line.
I had Someone else give me an estimate based on 911's findings.
Today, I have paid $3750.00 for a totally unnecessary repair. The leak of the coolant was not in the coil. When the new roof was installed, a nail punctured the copper tube in the attic. It coast $350.00 to repair the ACTUAL problem.
it's eas

My A/C broke down in 112 degree weather. It was almost 90 degrees inside. My home warranty company did nothing for 2 days and then said it would be 2 more days because they close on the weekend. So I went online and found Cactus Valley HVAC who was still open at almost 7pm. I texted and got an almost immediate response and within in minutes after that had someone scheduled to come out the same night - between 8 and 10. The owner, Richard, called to say when he was on his way, showed up with a very friendly attitude (not grumpy for having to work so late), knew what he needed to do and fixed the blower for my A\C very quickly. He also showed me the bad part. I am so pleased with this company and highly recommend them.

Highly recommend!! Mike really knows his craft! Great communication skills. He either answers his phone or calls back promptly.  On time and efficient. He doesn't try sell us stuff we don't need. So grateful we found someone honest and talented!

These guys are the best. My a/c unit stopped working and I had a different company come out and do a diagnostic check and quoted me in the thousands. I contacted these guys to get a second opinion and in the same day they were out here checking it out. They gave me a proper diagnosis and price for repairs. They fully explained what was wrong and didn't try to pressure me into using them right away. Once we we're ready to do the repairs they were able to get me an appointment right away. The tech showed up on time, he was professional and nice. He worked fast and my unit was up and running again right away. Highly recommend this company! We are very happy with their service.

Made appointment for gutter installation. Joe said he was a month out for scheduling. I setup date for my job. Joe was MIA. No response to calls and texts.

We have our RV located in an RV park up in Pine, AZ.
Last June(2018), we had trouble with our AC unit and after calling around to different RV repair/service companies we were told they were booked out 2 weeks in advance and one RV repairman near Payson told us Pine was too far to come to work on an RV... Really ?
 So I called North Mechanical and they said Yes, not only will we come out the next day but we're certified for Dometic service. (Dometic is a common brand of RV AC units and refrigerators etc).
 The guy that came was on time, very polite and all around good guy and had our issues addressed quickly.
Tuesday 11/13/18 we arrived in Pine to find our propane regulator leaking. I found a regulator at a Payson hardware store and went home and installed it and when I turned the gas back on it began spewing propane out of the vent on the regulator. I thought I had used improper fittings after talking to just about every hardware, propane parts places, RV repair people who were as usual booked solid. Everyone had a different opinion as to why the regulator was doing what it was doing. Now I was confused and compressed highly flammable gas is nothing to mess with so I once again contacted North Mechanical, explained my situation and also I had no heat and couldn't use our cook stove. Night time lows were 20 degrees in Pine and it was a long cold night but Darin North juggled schedules and had a tech out to us that next day.
Again, problem quickly solved, another great tech who was very polite, professional and right on time.
We have heat and can cook again thanks to North mechanical.
Good Job !!!!

BEWARE!!! I had this company come out to service my AC unit which, although older, WAS WORKING PERFECTLY BEFORE THEY CAME OVER. I just wanted to have it serviced before summer hit. Well, the guy came out and showed me photos of everything that needed fixing. Then their technicians proceeded to vandalize my AC unit. I called the company, never got a call back, and their employee said the owner, Carl Weaver, E. Thunderbird Rd Suite 731, Phoenix, said they wouldn't fix it unless I paid for the needed parts (over $2000).
This company baits people through an ad for cheap AC tuning, then they drum up further business for themselves after their technicians purposely break things on the unit.
They may end up in court with me.
My advice--- get a reputable company. They may charge more for a service call, but they won't vandalize your ac which will end up costing you lots more.
I'm having heart problems, and my blood pressure went waaaay up and pulse over 145 because of this company. I'm 68 and sure don't need this nonsense. This company is willing to take advantage of a 68 year old woman because of greed.
Two days later.... my home warranty serviceman came out. I happen to have a company which services the homes they insure (I just found out--Broward's). Their technician went up on the roof and took a video (too large to upload), but found out that Merlin's technician CUT THE WIRE TO MY AC MOTOR!!! This is vandalism. I have called the police. I have uploaded my home warranty receipt showing that the wire was cut.
In addition, they did something to my contactor. It was not broken before they came over as the unit was not running while in off position. But after they left it was.
Merlin's technicians actually vandalised my AC unit.
