   Verified Sammy and Ben were great!  Ben handled the logistics and was on point the entire time.  They were super quick and were able to get to my place within the hour to replace my water heater.  Sammy the tech was quick and efficient.  In and out in about an hour and did a great job on the install.  This is the second time I have used Quick and will continue using them.

   Verified The company, starting with Greg and Ben, then Brandon and Adam, were not just conscientious and courteous but extremely valuable in their consultative capacity.  In contrast to others I have dealt with, they truly sought to inform me rather than trying to drive my decision or to "close a sale."  I discussed frankly my "DIY" alternative and there was no pessimism or pressure, and I got the answers I needed to finalize my decision to replace, and the same with the more complex decision and tradeoffs of going tankless, and also they alerted me to the fact that I do not have a water pressure regulator, but, again, purely informatively, not in a "sales" mode, and referred me to resources to study further.  I consider the price to have been competitive and also I have confidence in their guidance on the right model.  They were punctual and once you know what you want, it is great to have it fully accomplished the next day.  I recommend very highly the professionals who worked with me and the company they represent.
