King Mechanical LLC

I’m writing about my experience with King Mechanical to save people from the expensive and frustrating mistake I made by hiring Frank Marquez and his company, King Mechanical, to install a new Trane AC unit at my home.

I paid King mechanical over +$5K cash to replace my AC unit. A contractor working outside heard the loud clattering noise the HVAC unit was making and commented that something was wrong with my brand new AC unit. The owner of King Mechanical, Frank Marquez, was called. Marquez said he would send someone to evaluate the banging noise in the new unit. One month later, King Mechanical had not sent a technician to my home or even contacted me about making an appointment. Multiple calls over multiple months with the same result. He would promise to evaluate the loud banging sound on my brand-new unit. Then he would not show up. By this time, I was upset. I had a faulty AC unit and was asking for a service call from the company that I paid a significant amount of money to install. King Mechanical would not even send a tech to check on the problem.

After 10 months of calling and texting without replies or responses from the owner of King Mechanical, I sent a certified letter. Only then was a repair tech sent out and he confirmed that the AC unit should not be making any noise as he heard. A month later, King Mechanical came out to “repair” my brand new AC unit.

A little over 4 months later I woke to a constant, loud banging sound while the unit was running. I went outside and recorded a video and sent it to the owner, Frank Marquez. Something had broken loose and was banging around inside the unit. This is in the middle of the Arizona summer with 115-degree heat. (see video)

Marquez’s response? “I’m booked out for 2 days. I can't drop everything for you”. What? In the text exchange, he repeated that he takes care of his customers and he stands behind his manufacturers.

Two days later at 2 am the unit completely exploded. I had no AC with a house full of kids. He stopped responding at all.

I reported him to the Contractors board. By the way, an inspection by the Contractors' Board takes 3 to 4 weeks. I obviously couldn't live with a broken AC unit in August in Phoenix that long. I had to pay a second HVAC company $2000 to repair the faulty AC unit installed and the substandard repair work performed by King Mechanical and Frank Marquez.

The Contractor Board inspector said he couldn't evaluate King Mechanical's work because of the emergency repair work. Frank then told me he wouldn't honor any warranty for the unit he installed. What a shock! I guess he felt more confident he wouldn't get in trouble for his shoddy install and repair.

The most troubling part of hiring King Mechanical to install the HVAC unit in my Phoenix home is that throughout this whole ordeal, the owner of King Mechanical had no feelings of obligation to the new HVAC unit he installed or the damage his repair caused. King Mechanical would not even schedule an emergency repair when his AC unit completely broke down. He knew I had 4 children in my home in the sweltering heat of summer. He wouldn't return my texts or calls. ( see video)

I expected a reliable AC unit and a company who stands behind their product and their service. Arizona has many HVAC companies that place quality products, provide quality service to their customers after they get paid. These companies make AC repairs that will not destroy the AC unit. King Mechanical is NOT one of these companies. When my King Mechanical AC install did not go right, the owner would not make it right. When the AC unit broke down, he would not help. In fact, the owner of King Mechanical NEVER responded unless he thought he was going to get in trouble.

Frank Marquez will take your money and disappear. King Mechanical does not stand behind its workmanship. Do not make the expensive mistake of hiring King Mechanical for HVAC repair and AC installation in Phoenix.

I had a few other quotes for a new air conditioning unit on my home in Tempe, but Frank came out and gave an extremely fair price right away without any going back and forth- felt comfortable with him, and could tell he has a lot of experience and confidence about his work and business. I would give him 5 stars just for being up front, honest, and for giving me a good price without any pushy sales hoopla. Grateful to have this new unit before the summer temps invade! Highly recommend them. Hard working guys and very professional. Save yourself the time and energy and just have Frank give you an estimate first!

King Mechanical is great. We had a dual phase heating/cooling system replaced and we were really impressed with the professionalism and pricing. Frank is very responsive and we were able to get something scheduled quickly. In addition, the team working on our house spent the time to make sure everything was working and our concerns were addressed. Overall, we were very impressed and grateful for King Mechanical!

We used king mechanical about 3 years ago when we replaced 3 ac units in our house. At first everything seemed great, install was much quicker than we expected, but everything seemed to have gone smooth.

The issues started about 2 months after install. The condensation pan to one of units started leaking, we called them out and they said there was a clog and that’s why it caused a leak in my ceiling. There should have been no clog, that should have been cleaned before it was installed. Then A few weeks later one of the brand new thermostats they installed stopped working, they pretty much told me I was on my own with that and I had to call the thermostat company and I ended up installing a new one myself. Now lets forward to November, so about 6 months after install, we try to turn the heat on down stairs and it doesn’t work, we call them back out. They came out and said they got the heat working, GREAT! fast forward a few months later we go to use the air where they fixed the heat… guess what the a/c doesn’t work 😂😡 we have had to call them out literally every 6 months because we can either get heat or a/c, but we can’t have both. Now it’s just about 3 years later, I have had 2 condensation pans leaks, and 2 out of the 3 brand new units do not work. They will not answer phone calls or texts. after this review I will also be reporting to the bbb and the ROC.

Edit… we will give you a call, thanks for the response. The purchase wasn’t under my name, it was under my husbands name which is why it didn’t show in your system.

I had storm damage while away and came home to deal with insurance because of roof, AC/Heater damage with the casing open and return elbow vent shifted and detached from roof. My AC was only one year old. It was a Sunday and rain was expected soon. I contacted previous AC installers and 2 other companies. King was the only one who responded and offered to come out. My neighbor recommended them and I understand why. They are professional, very responsive and do a great job! Frank will work with you as well. He answered all my questions and concerns.

Usually I do not write reviews but I chose to write one for this company even though I did not use their service. I was in need for 5T heat pump replacement. I called numerous vendors in valley for best price. Out of all vendors I had one of the best quote from Frank. Frank was very professional and provided me with many options with different price bases. His quotes were very good. I just could not use them as our schedule had a little conflict and Franks was very flexible to make it work for me but I did not have much flexibility on my end. I would recommend this company based on Frank's honesty and professionalism.

Francisco provided several reasonable options to replace our two Heat Pump/AC units. Once we decided on a brand the King Mechanical crew scheduled the replace according to our schedule. They were excellent in communicating when they would start and how the process would work (crew would come out and remove old units - replacement units would show up later in the day to be installed).

Francisco and his crew were courteous, polite, and were very good at cleaning up after themselves.

I appreciate that King Mechanical fills out and sends the warranty, rather than having to complete the registration myself.

I would highly recommend King Mechanical for a fair priced bid, expedient installation, and overall great experience.

Thanks you Francisco and team!

My Ac had a major leak in it, the air coming out of it felt hot and would not run fast, I made a phone call to about 6 places when I came across king mechanical, Frank scheduled me an appointment within the next few hours. The job was done with the finest materials! I can for sure say that king mechanical has yet now another satisfied costumer!!

I collected many bids for replacing the A/C heat pump package for my home. I found Francisco Marquez of King Mechanical to be the most competitive. I don't usually take the lowest bid, but when he came out to my home I felt more comfortable with him than any other vendor. There was no pushiness. He was very informative. I purchased a nest thermostat and he installed it when he installed my A/C system. He even taught me how to use this high tech stuff, and didn't ask to get paid for that. Very clean work, and very professional. His price was all inclusive, and there were no hidden fees.
Even though his business is relatively new, he advised me he has worked many years in this profession. I got a good review from the board of registered contractors when I called to inquire about his company.

King Mechanical is amazing from top to bottom. I called them on a weekend and they were able to schedule me and get a crane in line for the AC swap on Monday.

I had a 12 year old unit that broke down twice this summer and got other companies to quote me for a 3 ton unit. Frank got me exactly what the competition offered for less (i compared model numbers)I ands able to get the install done quicker than anyone in the valley. Did I mention he lined everything up over the weekend yet still the most affordable option.

Don't pass on King Mechanical. They are passionate about being problem solvers, working with you and your needs and I can assure you I called a lot of places and his price was the best with the same labor warranty the others offered.
