HVAC reviews in Cypress, Texas

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.

Awesome people.... friendly, professional service. Probably took 2x longer to get there than to fix the problem.

This company really wasted my time! I ended up finding another company! Their price/service are really not reasonable if you compare with other companies!

This is a very professional and trustworthy company. Our technician was very informative. This was our second time dealing with this company. I highly recommended them.

Technician David was very thorough checking my system and explaining everything answering all questions I needed answered to make decision about repairs/replacements.

Extremely fast diagnosis and repair! Replaced upstairs furnace blower motor and squirrel cage. Definitely my go to for air conditioner issues.

I had an initial visit today from David with Texas American Air who was very courteous and professional. This young man really put my mind at ease while discussing issues with AC unit.

Andrew took the time to explain the details of our AC issue, arrived prepared and our AC is running again smoothly. Thank you Texas American Air for the professional service

Had a problem with my heater and David was able to come out to fix the issue within hours. He was very polite and courteous and more importantly explained everything out thoroughly. Very good and honest work.

Fast, friendly and a fair price. Andrew came within a short time of me calling for an appointment and diagnosed my problem. He answered all of my questions (there were many) with a smile and discussed my options and his recommendations. I never felt like he was trying to upsell or pressure me. Needed a new system due to Freon leak. New system was installed in only a few hours. Runs quiet and cools great! Thank you!!!
