Las Vegas Air Conditioning came out the day before we were set to leave on vacation. Couldn't leave our pets at home in a hot house for over a week, so we needed the unit fixed asap. The initial part they tried to replace didn't solve the issue, but they managed to replace the entire unit in a single day, which was amazing. Stayed until late that night to be sure it was done, can't express how great their techs were and how hard they worked.

We did have some loudness from the new unit initially. Their tech, Micheal came out today and figured out the noise was coming from pipes inside the wall not insulated properly (not their fault since those pipes were installed by the builder, but the new more powerful unit made it more noticeable). He spent all day working to open the wall and fix, going beyond our expectations. Great service and all of their techs (Michael was great!) were very nice and really worked their collective butts off to get the repairs done quickly. The owners take a deep interest in any issues and respond quickly and directly, which is rare to find these days. Would highly recommend to anyone needing their AC worked on.

Las Vegas Air Conditioning is very professional from start to finish. The receptionist took my call and scheduled for a next day appointment. On the day of the appointment Andre B. called me to let me know he was about 30 minutes away. When he got to my house he let me know what was wrong with my air conditioner and gave me excellent tips on how to maintain it to ensure longevity. He fixed my air conditioner in record time was very professional. I highly recommend Las Vegas Air Conditioning for all your hvac needs.

We have been without heat for a couple days. It's been unusually cold this week, Murphy's law, right! Because of our work schedule we had to wait until Saturday to call someone. I'm sure glad we called this company. They were very friendly, efficient, honest and knowledgeable. Turned out we needed a new motor for the heater. Their prices were VERY reasonable, and our technician Ricky was VERY professional and a super nice guy.

He had the problem diagnosed, and repaired in under 2 hours. We are warm and able to enjoy the rest of our weekend in comfort. I know they had a full schedule this weekend, but they still fit us in and took care businesses. I would highly recommend this company.

I couldn't possibly be happier. So glad I found this company! We've had very bad experiences with A/C companies in the past and now those days are over. Our technician was a real pro, on time, informative and efficient.
