Todo estaba bien hasta que una parte se daño y esta bajo garantía me cobraron $550 solo por el labor. Cuando ne quje solo me descontaron $55 creo que es muy elevado los costosPosted on BEATRIZ GONZALEZTrustindex verifies that the original source of the review is Google. I had been very satisfied with Global Air since the 1st time that I contacted them, this was 4 years ago, when they installed a new a/c equipment. They come on time and they go thru the whole process very quickly. Today the technician came for maintenance and he explained me step by step what he did and even showed me pictures. The technician also found out that something was wrong with the motor (blower) and immediately addressed that with the company, since I still have warranty, they are not charging any extra. The prices are very affordable and they do whatever they can to accommodate to your needs. I am a happy customer and I recommend this company and their staff 💯 %!Posted on yenifer canulTrustindex verifies that the original source of the review is Google. I had an incredible experience with this company “ Global Air service” they installed my new AC unit, thermostat, vents, and ducts. They offer the best prices in Houston and top-notch service. From start to finish, everything was completed in just one day. They came by for an estimate on Monday to assess the situation, and by Tuesday morning, they were already setting up all the new equipment. By the time I got home from work, the house was cool and comfortable. The speed and efficiency of their work were truly impressive. A special thanks to Jaime Londono, the HVAC specialist, who was absolutely amazing. He went above and beyond to make sure everything was done right and that the entire process went smoothly. His professionalism and dedication really stood out. I highly recommend this company to anyone looking for quality service. On top of everything, despite having low credit and needing a co-signer, I was still approved with an affordable monthly payment. It was such a smooth and satisfying process.
