Reviews of local pros in Cypress, Texas

Excellent service, very professional and extremely affordable. Very dependable and trustworthy.

Absolutely amazing and professional group of guys! They were out the next day. They never pressured you or tried to sell you anything that you didn’t need and The prices were spot on. I would definitely recommend these guys!

They’ve been fantastic. Installed systems at two of my friends, and my own a year ago at a great price and great installation. I just had a proble just now, from the system installed a year ago and the owner jumped in his truck right away was at my house in 30 minutes, spent an hour troubleshooting,and it ended up being my own breaker in the garage. No charge, and great guys.

I am very satisfied with your service. I have been using this service for several years, the last one was the cleaning of the ducts, which I am very happy about. I highly recommend the service of this company.

The staff showed up on the same day within a few hours.
I was impressed with their knowledge. The techs knew what they were doing and fixed the issues quickly. I will continue to call GSM when i need my ac unit serviced.

Absolutely fantastic! They are the most reliable and reasonable in our area. Staff is 100% trained in all makes and models of AC units. They didn't try to sell me a new unit but fixed the electrical box on AC. He explained to me what was going happen in the industry with the new freon requirements coming Jan 1st..this company is one I have been looking for...small family owned low overhead.
Thanks again for a great job and a pleasure meeting you.

Regards,
Mike

I’ve been a client since 2012. I love that I can trust the performance of his work. I can recommend him to friends and family with absolutely no worries. I’ve even recommended him to my clients and he’s made time for them adding them to his schedule. Thank you GSM you are appreciated.

I had an outstanding experience with GSM A/C & General Contractor! From the first call to the final service, their team was professional, prompt, and incredibly knowledgeable. They quickly diagnosed the issue with my HVAC system and had it running smoothly in no time. What impressed me most was their attention to detail, honesty, and willingness to explain everything clearly.

The technicians were courteous, respectful of my home, and left everything clean and tidy. It’s rare to find a company that delivers such high-quality service with integrity and fair pricing. I highly recommend GSM A/C to anyone looking for reliable, top-notch HVAC services. Thank you for your excellent work!

Big thanks to Michel, Guillermo, and his crew! I’ve been looking a week for someone to fix my AC and nobody was able to assist me, but GSM was able to come out and get the job done the same day. They were efficient and detail oriented. They are very knowledgeable and went extra steps to make sure my unit was working smoothly. Would highly recommend them to anyone.

Guillermo and his team were very professional. They took extra steps and made an extra visit to ensure everything was working properly. We really appreciated that he wasn’t just trying to insist we purchase an entire new unit, and instead gave us a more affordable and reliable solution. We’ll definitely use GSM again in the future, they took terrific care of us!

GSM AC INC provides exceptional service when it comes to air conditioning solutions. During my recent experience, Guillermo proved to be both helpful and knowledgeable in diagnosing the issues with my system. His explanations were clear, making it easier for me to understand the various aspects affecting my air conditioning. The company offers cost-effective options and demonstrates reliability throughout the entire process. I wholeheartedly recommend GSM AC INC for their professionalism and expertise in delivering effective solutions for air conditioning needs.

Michel and Guerrero, and others came mid of last year to install our Indoor A/C unit, and did a very good job. They also worked with our payment method.
Today Michel and 2 other guys came over to replace our outdoor unit of over 19years old, they were pretty fast about it and the new unit is blowing well and really quiet. And like last year, he was kind enough to work with our payment plan.
I greatly recommend their service because they will work with you and will do a great job.

Guillermo and his team at GSM A/C General & Contractor Inc. provided the best AC service and repair we’ve ever experienced. They went above and beyond—driving all the way to League City to fix our AC quickly and professionally. Guillermo is incredibly knowledgeable and took the time to educate us on how to make our system more efficient, helping us save on electric bills and reduce future maintenance costs. Exceptional service from start to finish—highly recommend!

They are the best good price very professional I recommend them. Daikin certified and trained to install the new Japanese daikin Goodman variable speed AC. In The picture the only company from Texas attended the Japanese convention ( be the pro ).

I called G S M yesterday morning and got a time scheduled in the same day! Guillermo called and gave the time of arrival, came in, assessed the situation and gave advice to what needs to be done, he was professional and honest and did not suggest to repair or replace anything that wasn't needed, and today Michael came in and finished the job, he was efficient and clean, no mess left behind, Highly recommend this company, i will refer this company to my friends and family in the future.

Could not have been happier with the service, my technician Michel showed up and fixed our problem promptly. We thought we had a bigger issue, but he found the problem within minutes very professional. They will be the only company I use for my AC in general contractor needs.

This team was great. I am selling my home at the moment and the buyers had some concerns that their inspector brought to their attention that they asked us to address. GSM had a crew of technicians made it out to my home within the day to take look at my system. They made the necessary repairs, sealed ducts and plenum, and checked to make sure that the system was working properly. They gave me some items to look at and consider on my next home as well. They were quick to arrive and on time, did not waste time with completing the work, and they did it for a fair price. And, they provided an invoice with pictures that I could provide my buyers to put their mind at ease. Would definitely recommend them!

They are best company ever. David the tech made sure he got our a/c working.
