Best Heating & Air Conditioning/HVAC in Phoenix, AZ

Great response and communication- Jason supplied a through quote at a great price and offered many options. Arrived on time and was helpful!

Robert did an awesome job for a reasonable price. Good attitude, worked super hard, got it done in a timely fashion. Will definitely be using him again for anything we need hvac related. Recommend him highly. He replaced our air handler and condenser and relocated it all in one day.

Very helpful and honest company. They were able to complete the requested work very quickly. I would definitely use them again.

My HVAC broke down end of August, Heat warning in effect and literally 2 hours after I called McMillin Air their technician Lalo had my A/C up and running again!!! I can't begin to tell you how impressed and grateful I am! They will have all of my future business. A million thanks is not enough.

Had a wonder experience! Thank you Phil Kneisel for taking your time to better explain the science behind runniing your air more effeciently in this desert heat!!

My parents purchased a home and needed a new unit and new ductwork. LRG did a fantastic job. The pricing was fair and the work was completed fairly quickly. Very professional. LRG is the way to go!

This will be our third summer in AZ. First two companies that came out only wanted to sell us on a yearly maintenance plan and it didn't seem they really did much. Ryan was certainly a relief. He was the first company that actually washed the coils! Felt very comfortable that I was dealing with an honest company for a change. Comfort will definitely be who we call next Spring to get the AC ready for the summer.

Jake is an outstanding guy! On time, friendly, good service and attention to detail!
Thank you

I'm looking to replace a 5 ton split and was contacted by K&K, they set up a day and time to swing by for an estimate, but they were running late and never called. So I texted their contact to cancel.

Sorry folks, but being late for a scheduled appointment and a no call/no show in our industry is a dealbreaker. If you can't be on time, how dependable will you be with the demolition of the existing system, getting the new equipment, ductwork, piping, t-stat, and insulation to the job in a timely manner; then installing it, charging the lines, doing start-up, and commissioning the new system after a blow-down?

I put 25 years working in the Sheet Metal trade here in Arizona--17 of those years as a Foreman on large commercial and industrial projects before I got into estimating Mechanical systems. So here's a tip guys: In my trade and current profession, if you're on time, you're late.

It would be in your best interest to embrace this hard fact, so welcome to the valley, Freshmen. Service companies die on the vine all the time out here. Best of luck to you.

Reliance is a great company!  Had an issue with our AC on the weekend during an excessive heat warning.  Brayden showed up within 15 minutes,  we were lucky that he was close.  Diagnosed the issue within minutes and had our unit up and running again.  Thank you Reliance!

Great service and attentive quote for an a.c. zone motor replacement. Kept me in the loop on timing not ship the part in. Then quick scheduling and a friendly and efficient tech for a good fair price. I recommend and will call them first for my a.c. needs.

I've using day and night a c. For years any problem with ac. There the company to call techs. Know  there job well

Both of our AC units were on their last leg, house is about 20yrs old. I got quotes from 5 different companies, many of which were much larger, lots of the larger ones sent out dedicated sales people which was kind of a red flag for me that they need to charge higher prices for all of their extra employees. I'm really glad that I found DeModica Air, Jon Jon came out the day after I called him, explained all of my options, including patching my existing units which he said he could get them to last probably another 3 years. But he recommended replacement and we are glad we went with his recommendation. He had both units replaced, along with the air handlers in just 2 days. I highly recommend giving them a shot, at least invite them to give you a quote.

They are fabulous and so very knowledgeable.   Came out, gave me an estimate and we set a date and time.  I had to have a complete air/heating system put in.  They came out, did their job which was greater than it should have been but the one that had to be removed was not done as well as it could have been.  Apparently, because of that, they had more work to do.  Never had a complaint, just did what had to be done.  They are a full service company and they will be my go to for all my heating and plumbing needs.  They are as honest as the day is long and besides being very professional,they are very congenial.   I cannot say enough about this guys.  They are terrific.

Last month our a/c stopped working. We filed a claim with our home warranty company on a Saturday and I was so worried that we were going to be without a/c for several days. Being August, 8 months pregnant, and also having a 1 year old I was very concerned! My husband left a message on Sunday, and someone contacted him back letting him know they would be out early Monday. The communication was great and the tech who came had the part we needed on hand and fixed it right away. I was so thankful! Great customer service and no further problems, couldn't ask for better!

As a Real Estate Broker having a reliable and honest AC company to refer to my clients is extremely important.  Kevin serviced all three of my AC units today and did a great job. He showed up on time and did excellent work.  He is very thorough and extremely honest.

I found King heating, plumbing, and AC LLC when my home warranty company  (Old Republic) sent Marc out to take a look at my AC unit that was not producing cold air. I cannot say enough good things about Marc. He was extremely nice, honest, trustworthy, and took the time to explain to me the problem and what can be done to fix it. He took his time and made sure the job was done right. The problem was that we were low on refrigerant and he made sure there were no visible leaks before pumping more refrigerant in the unit. He was able to fix our air conditioner and now my family doesn't have to live in a hot house anymore. This is by far the best experience I've had with a heating/cooling and plumbing company. I highly recommend this company and I even more highly recommend them sending Marc out to your house!

Been doing business for 6 months with them. This is the fourth repair man. Each time they find extra work that cost in excess of 500 dollars. The question is why the first 3 guys don't find the same problems. This is on top of the very expensive maintenance package. Dishonest?
So far every fix took two trips

I was having a tough time finding someone to fix my Midea Air-handler, as it is not a common brand of A/C.  When I called 1800Plumber+Air, Ben answered the phone and listened to exactly what the issue was- he took down the model of my unit and actually talked through the repairs with his tech before sending him out.  The other companies I called (Goettl and George Brazil)just have an answering service and they do not relay any important info to their techs, thus having them show up only to say they could not fix it or find parts.  
Ben listened to my issues and the awful experiences i had at the other places and said he would take care of it for me and that the tech he was sending, Travis - was the best.  Travis showed up and quickly fixed my A/C (needed a new control board) and only charged me half of what the others said a new board would cost if they could find one to fit my unit.  I will never call anyone else again but these guys for plumbing and A/C!!!

Friday morning, just about to finish my shower and I go to shut off the water and the handle comes off in my hand. The water is still on full blast and it's hot as hell. I've got no way to shut it down. The top of the stem is still in the handle. It twisted right off.
I quickly dried off, through on some clothes, and headed out to the garage and shut off the hot water at the tank. Hot is off but still have a little cold running. Time to call a plumber.
I ask Google for a plumber in the Sun City West area. I get a bunch. Call the first...they can't come today. Call the second...cant get there till Monday. Third was Canyon State...She told me they could have a plumber there in two hours. Great, I said.  Send him over.
He came on time, fixed the problem (it wasn't easy) in an hour and he was gone.
The availability was great, he was very professional, (knew what he was doing), and the price was reasonable. I couldn't have asked for more. I've never used them before but they will be my first call next time.
