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.

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!

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.

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.

Our nearly 20 year old AC unit died. I remembered seeing a King Mechanical truck in our neighborhood and talking to the owner, who was happy with their equipment and work, so I called. I spoke directly with Frank, the owner, who helped me determine what kind of unit I needed and whether it would be cost effective to upgrade to a higher efficiency unit. The heat was miserable in the house, but Frank and crew were onsite at 8:30am the next morning, and he assured me we won't leave until it's working. They finished a difficult install (unit in the attic and outside unit difficult to remove) at 7:30 pm and we had cooling once again. The price was reasonable for good equipment with a good warranty. They guys were hard working, clean, cheerful, and professional. I would use KIng Mechanical again, and recommend them to you for your heating/AC needs.

The old AC was from a different company I always had issues with it and they were never willing to come take a look at it, they continued to make silly excuses for the next 6 months. I got fed up with it and looked for a different company Kind Mechanical was able to book me an appointment and come take a look at it that same day !! Frank himself was the one who assigned me to Ayax who took a look at my AC and replaced it that night. I’m in love with it now everything was so neat and organized ! It’s so crazy that this company had such had workers!

Our ac went out at my personal home and Frank was quick to respond. We literally had a new ac installed the next morning. Then a few days later my business ac went down and Frank assessed it quickly. great well organized team here and I am looking forward to working with them in the future. First ac company I ever met that actually cares about their customers and has reasonable prices.

We needed a new AC but they replaced all the parts and now it's running like new! King Mechanical, LLC was quick to help us with our needs. They also installed a new thermostat and it didn't take long at all. I highly recommend them. Very friendly, on time, inexpensive and fast!!!

My A/C broke and it needed to be replaced I called King mechanical the owner came to my house in 30 minutes he gave me an amazing deal on a new A/C unit. The installers came in record time and installed the new A/C unit. This is a wonderful company I am extremely satisfied with there work. Friendly professional and reasonable prices. I would highly recommend this company.

My experience with king mechanical was amazing I have a little girl and we are very cautious because of Covid. Cris had his mask on throughout the whole procedure, mind you the weather is getting a little more sunny, yet he didn’t stop working until he was fully done. I love this company and would definitely use them again.I’m

Fast response, great service and amazing reasonable pricing! Gives you a peace of mind knowing you found a relaiable company to take care of your AC needs, specially here in AZ.. Will definitely be contacting King Mechanical for our future Air Conditioning needs and referring them as they deserve it for an outstanding job well done! They replaced our old AC unit with the new one whiten an hour I was amazed with the knowledge and fast work they did! I am a happy customer

I called King Mechanical to inquire about 2 new ac units for my home. 2 days later I am enjoying the quite cool of 2 Trane AC units that were carefully installed by Frank and his team. I appreciate the fast, professional service and great price.

Frank and his team are rockstars, they replaced 4 air conditioning systems for me in the summer of 2019. Price was fair and they were out fast. I would recommend them to any home owner or landlord looking for quality work and great pricing.

I am maintenance supervisor for Chiro Plus Chiropractic centers and when our regular AC company went out of business, and we needed a new 4 ton split system, we found ourselves in need of someone new. I called several companies and started scheduling appointments, some for the following week. When I called Frank he said he would be right over, and he was here in thirty minutes! After he and my boss agreed on a price (which was great) Frank asked how late I could be there because I specialize in one day installation. Needless to say, I was skeptical, but Frank is a man of his word and he got right to work. He scheduled a crane, picked up the equipment, and brought out a three man crew within the hour and they got our new system installed by the end of the day, just like he said. I'm happy, my boss is happy and our patients are happy. If you want someone who puts the customer first and DOES WHAT HE SAYS HE WILL DO, Call Frank at King Mechanical.

The best AC company in the entire state of Arizona! Clever technicians and great leadership! Alarico is the Tech that came and replaced the fuse on my 3 months old unit that was also installed by King AC and that i got it from them for the best price in the entire market. The fuse went out because of the heavy rain “Monsoon”. Called Frank and explained to him that i came back at 6:15pm from work to find the new AC not working. Frank dispatched Alarico in less than 10mins to my house! Alarico replaced the fuse in another 15mins and explained to me what happened and took off after and that was all free of charge. I do recommend King AC for new installations and general AC services! Simply the best! We all dealt with many AC companies and i writing this review based on my long experience with other AC providers. Thanks a million for the great Service King AC and please keep it up. Service is what makes the huge difference and stands out!

Their work is excellent. Me and my husband were very satisfied with the work done . We travel a lot and don’t have time to wait around for companies to fool around with prices , nor they themselves setting the dates on when they can come take a look at my AC so we're more than happy these people were fast and efficient when they came down on our own time to set up our new AC unit. So far so good.

Frank,
Thank you for doing such a superb job. Your crew is very knowledgeable and professional. I recommend King Mechanical to anyone who needs a new AC unit or service.
thank you for your expedient response!
we are now nice and cool.
Sam and Kathi Mclaughlin

I had my brand new air conditioner go out and King Mechanical. Came out with in 4 hours and found the problem. A roof rat had eaten thru the wiring. King Mechanical found the traces of a rat. They repaired the chewed up wires, and i bought a trap. End of problem. Thank you so much Francisco and guys for acting so fast on this.

The best Appliance Service we have ever had!

Frank and his crew were a “dream” to work with...from the initial phone conversation to a seamless installation.

Price, Quality and Service were outstanding...highly recommended ?

Just finished using King and Francisco for the second time. I called him for a service call and found that the unit was not fixable. He was out 2 days later and because there were tenants that needed it to happen quickly he had it in tested and happy people in 3 hours. I totally recommend these guys !!!

Excellent service. Very courteous, professional and friendly. Great price of air conditioner and furnace. Installed new thermostat and even adjusted air vents in house. I highly recommend King Mechanical, LLC.

Awesome company ! Had my AC for newly 2 years and suddenly broke down all of a sudden.
I was recommended this company and they were able to repair it in no time . They had it back up and running within the guaranteed time limit .
Runs amazing now maybe even perhaps better than before .

I want to give their team and the owner Frank a big thx’s . My husband and I contacted this company due to some of the reviews , and I‘m actually shocked to see how great the results were. They came out to give me an estimate last Tuesday, then had my ac up and running by Wednesday due to my crazy schedule . (I was so glad they were able to work around that as well). They really took interests in stuff which I thought were the problems , and from there they were able to explain the procedures they were going to do, which I was thankful for because I didn’t want them making adjustments I might’ve not approved . Thx you guys all sm!

Very efficient, fast service, reasonable pricing, friendly! Amazing customer service highly recommended! After king mechanical llc service my a/c & heater unit has been working perfectly.
