Great service, on time, very respectful
Asters was super kind, professional, and timely with his service. Answered all of our questions and took time to explain service.
I've had 4 HVAC companies come out to try and fix 2 dampers in my 2 zone system that were backwards. They didn't even try to fix the dampers and looked dumbfounded and recommended a new HVAC system. Josh came out and immediately got to diagnosing the issue. Fixed my dampers and now I can cool both floors and give the system a break. 3 years and 5 companies to get it done but I've found the right company and technician. Thanks Josh and GeauxHVAC for the great service. Look forward to doing more business with you in the future.
Astor’s was great got in got out and fixed the problem ASAP. Great man to have on your team!
I called GeauxHVAC out for a routine heater and A/C maintenance cleaning, and I could not be more impressed with the whole experience. From start to finish, they were remarkably professional and completely transparent. I never felt that they were pushing unnecessary sales. They simply walked me through how my system was running and explained, in a way I could actually follow, how everything could work more efficiently. When I was ready to move forward with the recommended updates, they made scheduling and execution effortless. Communication from the office was wonderful. They sent reminders and provided real-time updates on when to expect the technician. Taylor arrived on a brutally hot afternoon after a tough prior job, but he stepped through the door with the brightest smile. He braved my sweltering attic, kept me informed throughout the process, replaced a burnt-out attic bulb, and meticulously swept up every stray bit of insulation before heading out. The difference is night and day! Our home at 74°F feels surprisingly crisp, and the unit no longer struggles against the Louisiana summer heat. The entire GeauxHVAC team is in sync, and I am so grateful for their care.
Joshua was very polite,knowledgeable and informative. He explained his troubleshooting process and the actions taken to resolve my hvac issues . He resolved a very important issue that apparently has existed since the installation of the unit years ago. My AC unit now runs more efficiently as designed. All done at a very reasonable price!
Tylor Bourque took care of business for me today, friendly, very informative! Still some work to do but he got my house cooling down just fine!
Keagan was extremely thorough with his evaluation and recommendations. He was also very patient with the process and answered all our questions in a quickly manner. He even lent us a portable until while our old unit was down. I highly recommend both Keagan and GeauxHVAC!
