2 weeks after moving into our house in June the back air conditioner stopped working. Having just moved to Las Vegas, I had no idea of who to call so I searched the internet and found Larson Air which had excellent reviews. The tech arrived 2 hours after I called and worked for 3 hours trying to revive the ancient air conditioner. As it turned out we needed not only a new air conditioner but also a new furnace both of which were installed by Larson 2 days later. Everyone from Larson was professional, personable and efficient every step of the way and the cost was reasonable. If you have a problem with your air conditioner or furnace forget the others, Larson is the ONLY company to call. Professional, Honest, Efficient, Highly Recommended!!
