Great service and great job on installing a new ac system.

I’ve had Mario and his team come out two separate times to work on two separate units and replace the coils. He’s friendly, responds quickly, and provides quality work a fair price. I will be using Master Mechanical for all AC and heating needs.

Mario and his team replaced my entire HVAC system. I noticed an issue with the vent from my furnace July 23rd, got in contact with Mario and he said someone would be out the week after to fix it. This is a big issue because the vent was not properly vented to the outside so therfore carbon monoxide is able to leak into the attic space. If i did not check the work my family could be dead. I have been trying to get ahold of Mario since no one has still been out to finish the job, still have not recieved a call back.Update: I still have not received a call back from Mario or anyone on his team, regarding this issue. I have left numerous messages and made numerous phone calls and have yet spoken to anyone about this problem. I am now forced to contact a different HVAC company to come out and finish the job Mario and his team were supposed to do originally. I would highly recommend choosing a different company for your HVAC needs.

These guys are fantastic! Ive had them perform a few different services at our home over the last 4 years ranging from duct replacement, A/C repair, and a whole new system replacement. Every time I have called on them, they have come out the same day. Jorge is knowledgeable, honest, and very fair and reasonable in pricing. Every technician that has come out has been friendly and addressed any concerns or questions I have had regarding the service performed. I would highly recommend this company to anyone for their A/C and heating needs.

They did an amazing job replacing our entire AC unit in our home. Highly recommend them! They came out the very next day that we called, so it was less than 24 hours for us to have a complete system installed with new ducts, dual zoned system and everything. They layed out painters cloth all over our home to keep the floors clean, and made sure to sweep up any dust after. They walked us through the system zand made sure we were familiar with everything before they left. Super friendly employees, and a very honest and reasonably priced company.

Awesome service very professional! Honest and very dependable and reasonable prices! You get exactly what you pay for and the crew who installs everything is very polite, clean and organized! I highly recommend them 100%

Im the landlord of the tenant who wrote a 1-star review and I have a completely different opinion. George and Mario have done over 30 jobs for me over the past few years. I have found them to be trustworthy, dependable and reasonably priced. I will continue to use them regularly.

Master Mechanical AC & Heating has done work for us both in our own private home and for our investment properties for many years. They have always been prompt in their responsiveness, fair in their pricing, honest and professional. We will continue to use them and refer anyone who asks to them.

Master Mechanical is a first class HVAC company. They gave me a written estimate to replace an aging residential unit. Their price was reasonable and I had them replace the entire unit. Mario, one of the owners, answered all my questions and I had a lot of questions. He explained the warranty in detail. Installation was completed as agreed and their quality of work was excellent. They did not leave any mess for me to clean up and I highly recommend this company.

Mario was honest and forthright, something you dont find every day in the HVAC industry. Very reasonable pricing, quality products and quick installation. His crew is personable and clean. Very good outcome to a tough situation. I highly recommend going with Master Mechanical.

George replaced my AC earlier this year. And, what a great experience! Arrived on time, looked over the entire system, explained the problem, gave me options on how I could handle and provided fair quotes for each option. As soon as I made the decision to replace the unit, he had his crew onsite with a new AC the next day. Crew completed the work quickly and cleaned up after they were done. Thank you Master Mechanical AC & Heating!

These kind folks work hard and do a good job. I am very happy with Mario and his team. They know what they are doing and will not BS you at all. Good and honest people and fair prices. I highly recommend them.

My home flooded during Harvey and during the renovation, I learned that the duct work for the HVAC system was from the original construction (1950s). I called the company whod been servicing my home for the past 10 years, but their bid seemed excessive. A family member whod used George and Mario suggested I call them. I was so glad I did. They showed up when they said they would, worked very efficiently to finish the job the same day and cleaned up all traces of the old material. Best of all the price was very fair! For future needs, I wouldnt dream of calling anyone else!

Very professional/ quick service very reliable/ have used them for years

My Day care was hot yesterday and full of Kids.... cant imagine! I called two companies which were overselling me something I did not need, then Afriend told me about Master Mechanical, and Mario came as soon as we could and fixed my AC and made all necessary recommendations that needed to be done to avoid future problems, but the importat thing is that he fixed it without pressuring me to buy new system like the other companies.I am very satisfied and recommend their great and honest service, They are not the cheapest but they have very competitive prices and their honesty counts more to me.Thanks Mario!

I HAD MY A/C SYSTEM INSTALLED LAST WEEK AND I COULDNT BE ANY HAPPIER, GREAT JOB, MY SYSTEM IS SO QUIET,COOLS FAST ......THE INSTALLING CREW WAS VERY POLITE, CLEAN AND VERY KNOWLEDGEABLE....THANKS GUYS--- AND I RECOMEND THEM TO EVERYBODY!

Great service,knowledable guys, and very affordable, I had my new ac system put in a week ago and it works super quiet and cools perfect!thanks guys and I recommend anyone shopping for new a/c...... to call them!

I wanted to tell you that 4 yrs ago, I had Mario and his crew come out and put a whole new HVAC system in my home with duct works ect., the guys knock out the whole job in one day, HONEST, HARDWORKING did I mention Honest ? System has been working flawlessly, I recommend my sister Master mechanical, cause she also need a HVAC system in her home, and my brother-in-law aswell and they where both very happy with the work them selves, I tell any body that is looking for HVAC give them a call, remember, cheapest is not all ways better, I rather pay a fair price than having to deal later with issues and bad customer service. I would recommend Mario and his crew, they will get the job done right if you are looking for Honest work give them a call PERIOD!

Due to the fact I knew exactly what I needed, Mario gave me a quote right over the phone for a Trane 2 stage complete system including new duct work, was almost $2000 less than Cy-Fair Mechanical for a comparable system. They also threw in a UV light and media filter and added another vent. They were a little more than another technician, but I chose them due to hearing good things about them from friends. The installers did a great job, my only complaint was they wired the furnace board and thermostat for a dual compressor system and not a two step scroll. Two step is 70% in first stage and dual would be 50% in first stage, so the blower was running too slow in first stage which could cause the coils to freeze or cause liquid refrigerant to back up into the compressor. I know about A/C systems so it wasnt a big deal to wire it to slow the fan down 20% vs 50% using the BK terminal on the board.I highly recommend them. It doesnt look like they install Trane anymore, mostly Amana and Goodman, but their website claims they can get other brands. Im personally not a fan of Amana and Goodman so I would only go with them today if they can install some of the other brands out there.

I used them almost 4yrs ago and have had problems ever since. If you ask who I am he will remember me.

I had quotes from other hvac companies...but master mechanical ac was not the cheapest but was the most competitive and offered more for less, we installed 3 complete hvac systems in our champion forest home, and now we are saving $$ and are very pleased with their work! I highly recomend Master Mechanical and their crew!

Very professional and friendly staff and best price in houston. I will definitely reccomended to anybody who wants a good unit with awesome price. Thank you mario, you are so flexible and helpfull, i appreciate that. I am so happy and excited with my new trane XR 😄😄😄

Mario is a great guy to deal with!!He spent over an hour with me the first time he came to our house and took the time to look at our A/C system and all ductwork. Was happy to answer any questions I had.I have a 2800sq ft house and have 19 year old 5-ton unit. I recvd bids from different companies up to $12000.....freankin rediculous. I had a new 5-ton Trane system installed yesterday for less than half of that. Mario and his crew came in and went to work, covered my carpet, and did a very neat job. It took 3 guys less than 7 hours. After the job he took me around the house and showed me the work they did and what they did with the new ductwork to improve flow.I am a hard person to impress and needless to say I am thouroughly impressed with Mario and his company.If you are reading this than you probably have some home A/C or heating problems, do not waste your time with anyone else CALL THESE GUYS!I wasted alot of time and effort and research and no one came close to Marios prices or customer service.THANKS AGAIN TO MARIO AND MASTER MECHANICAL A/C AND HEATING!

Great customer service!
