John and his team are simply amazing. It's nice to finally find an honest heating and air conditioning company here in Las Vegas. John actually took the time to explain exactly what was going on the proper maintenance plan to keep my new units running efficiently for years. I was so impressed that I signed up for the bi-annual maintenance plan. I can tell you it's a very good investment for anyone wanted to avoid that Ac breakdown when it's 110 degrees outside. Plus if you join his maintenance program you get PRIORITY service if your unit does break down during the summer when all companies are slammed. Definitely give these guys a call if you haven't tuned your unit yet this year...btw they also clean air ducts which will be next on my list.
