Had old unit replaced with 3 ton Trane unit. Called in the morning and a representative was at our home that evening. We agreed on a price and the unit was installed the next day. Great to work with and VERY responsive. Would highly recommend them. Also ...always answer the phone and do what they say they will. GREAT COMPANY!!!! read more

This company is the BEST! Installed a new system for us years ago and have responded immediately with any issues or questions we had. So so so honest and professional. Honored all warranties and they really do care. I recommended them to my friend and she loves them as well. If I was able to rate them a million s I would. read more

BEWARE.... If you're looking for a company that takes no responsibility in property damage then you're in the right place. In late July of 2024 this company install a new unit in my residence in doing so they damaged the existing drain line causing a slow leak between the walls of my bathroom and kitchen. After notifying the company of the extensive damages in May of 2025 they proceeded to tell me that they could move the drain line for an additional 900 dollars (I did it myself for 25 dollars) stating "well we didn't install the drain line" which is true they did not install it but for whatever reason they did decide to drill a hole directly next to it chipping a small hole into it. After having to replace my ENTIRE bathroom due to mold and water damage I have spent out of pocket 20000 dollars plus the 10000 they received for their services. Charging for a whole new unit to not do the job properly is disingenuous. Safe yourself money and hardship choose another company with honest business practices read more

Andrew came and did a summer service call this week and was great. I have used this company for several years now and Kim has been fantastic with scheduling a quick service date too. They have great prices and I'm very pleased with this company read more

The Free Estimate is $60 and the diagnosis was to start replacing expensive (thousands) parts where the next company simply found a Freon leak and repaired. Tech spoke no English, used his phone to translate. No Bueno. read more

Stay away. They replaced our units in 2023. Had several over hvac companies out to inspect since the install took place because my gut told me something didn't seem right. Each company told us that there were some corners cut during the install of our new units and that the sizes we were sold didn't make sense for the layout of our home. Disappointed. read more

Great- Everything u look for in repairs: Quick to come out, fast to repair, knowledgeable but can tell you in English, and only replaces the broken stuff. Doesn't try to upcharge you with lies about replacing everything like other companies. We will use them again for when we have problems! read more

I can't say anything on this person's business, but I will comment on his poor driving! He nearly rammed into the side of my car cause he decided he didn't want to exit onto 35. I honked to let him know I was there & he still proceeded to come into my lane. There was no blinker used until after the fact!! Very rude & aggressive. If his business ethics are the same as his driving ethics, I feel sorry for his customers! read more

I have such a great experience with this company, they strive for quality work and customer service. They came to my house and explain everything step by step, Jorge and his team are very knowledgeable and work hard to meet my expectations!!! read more

Great prices and great service! Desperately needed my Ac fixed but the prices were insane. They gave me a great quote and had everything fixed next day couldn't be happier read more

Called them to do some warranty work on a unit they did not install. They were thorough and did not pad with extra charges that the original installer and others tried to gouge us with. Will definitely work with them again. read more

Absolutely stellar job. Super reliable, responsive and honest. They are thorough in explaining the process and the equipment. read more

Great experience with repairing our AC unit. Tech, Jose showed up as promised, determined and explained the problem and repaired the unit at a reasonable cost in an hour. Our neighbor in Firewheel Reserve referred us and now we know we have a go to AC repair company! read more

Local and honest. Worked with Jorge to install a new HVAC unit and spray foam in the attic. He was easily the most clear and best priced bid. His team arrived promptly and installed exactly what he said he would. He also personally comes and checks on the installation and has troubleshot issues I was having. Just a good company owned by reliable people. Would easily use them again and have recommended other contractors to use them. read more

They replace my Unit for 5 tons, February 1 2020, I had call twice because AC unit stop working,the first time fix that the water was not circulating, now that I call again because Unit stop again, he said we need to paid more money to replace a Electrical wire, which my husband paid for it when he can to to do the contract, Mr.Mondragon,got angry because my husband told him, we have a 1 year labor guarantee, now he want us to paid him more money to come to do his. He charge us more than $6000. It has been 9 months.It is not fair that now he does not respet his Labor guarantee. read more

Excellent service, very professional and knowledgeable with the most competitive, reasonable pricing in the market (I priced 4 vendors and they were 20% below the next lowest bid). In an industry filled with shady characters, Jose and his team are a breath of fresh air. They went above and beyond to install my new Trane unit and then customized a Nest system for my house. A+++ on service, quality, communication, cleanliness and timing. They exceeded my expectations in every regard. Jose and his team were in constant communication with me and solved a difficult installation problem ahead of schedule and on budget. After the word gets around, I have no doubt that Mondragon will gain significant market share in the Dallas area. read more

What a great company ! Their reasonable, competitive price made it possible for us to have our brand new Trane HVAC system installed into our older home -built in the 1940's- which had never had central air before -and they did it in 2 days! Other companies quotes were astronomical. Jorge Mondragon and the crew went out of their way to accommodate our many special requests and we could not be happier. This was a difficult job - with limited, small attic space and several other factors which demanded special attention, and they did it all happily, efficiently, professionally and so quickly. They made it seem easy - even in the brutal Texas summer heat. For the first time in our 20+ years of living in our 3rd generation home, it is ice cold in here- just the way we like it ! I cannot thank Mondragon enough or recommend them more highly. They are the absolute best ! read more

In the absolute worst heat, this quiet, professional group labored to put in a complete new system (in our attic), rearranging our layout from top to bottom - they listened carefully to my requests and handled them all. I'm happy to say that we are 'freezing' - having to continually adjust our thermostat to newer higher settings (saving money and loving the cool). I did weeks of homework in selecting my system and my installer, and I highly recommend their services for quality and expertise. read more

Mondragon Mechanical made a mess of my house. I paid them over $5K to install a new hvac system that never worked right. I then had to hire a plumber and electrician to fix what they messed up. The owner José Luis Mondragon was very rude and vulgar during our interactions. Would not recommend. read more

We had Mondragon Mechanical come out through a referral from an electrician who worked on our house. We experienced quality work and great service on our new AC unit install. Everything was completely as expected -- they showed up on time, protected our floors, install went smoothly, they coordinated the warranty paperwork and inspection through our city. The inspector actually mentioned that the way they secured the interior unit in our attic was above and beyond and he sees a lot of companies taking short cuts. Great job! We will definitely use them again. read more

Mondragon Mechanical is absolutely wonderful! This company is definitely the best value for purchasing and installing a new HVAC unit. Jorge Mondragon thoroughly and patiently explained our repair and replacement options and offered the most competitive price on the market (compared to five quotes from major companies in the DFW area). Jorge's crew of licensed technicians were extremely hard-working and polite. The entire experience was as good as it gets: excellent value and service. read more

Worse experience ever, person who we talked to was rude to my elderly father. We haven't had our ac unit for more then two weeks and it quite working. Two different crews came out and none of them knew what to do. But they where quick to take payment. read more

Literally could not have been happier with my service from Mondragon. Jorge was super accessible for any and all questions, and NEVER tried to upsale me on anything. After getting other estimates, I gave him multiple opportunities to "upgrade" my unit/offer, and while he always said he/we could do whatever I wanted, he repeatedly would clarify what I actually needed vs what was potentially overkill. I can't imagine that his honesty didn't cost him quite a few dollars of profit. He threw in extra things along the way based on my questions/concerns, but our estimate never increased from day 1. And in fact, my foam insulation came in under estimate. We got new inside and outside units, old insulation removal, and foam insulation install. All was well under my 3 other estimates, without any sacrifice in quality, service, or time. My June electric bill has gone from $5-600 the last 2-3 yrs to around 200 this yr!! I have already recommended them to a couple of people, and will happily recommend again!! read more

Never using them again. Bad customer service They over charge for their services on parts that are not needed.

Jose Luis at Mondragon Mechanical is as good as it gets. Truly professional service. Always honest and direct. MM has come out to my home on separate occasions and saved me a good amount of money just by recommending what I should do service-wise with my AC/Heat unit at home. I have recommended him to friends and family, and will continue to do so, as I know he will treat them with the same level of respect and expertise as he has done in the past. If you are in need of a great Heating/AC service, reach out to MM you will not be disappointed! read more
