Posted by James P. on 05/03/2019 I have had Quality Ambient over for both HVAC service and repair, and eventually had them do a system replacement based on their diagnoses and recommendations. I like the way that they communicate, offer options, discuss the pros and cons of the options and also the cost and estimated return on investment based on the options chosen. They provided fair and competitive pricing, and based on these past experiences, will highly recommend them to others.

Posted by Alan M. on 05/26/2021 I worked directly with Danny. He was very courteous, knowledgeable, and talked me through my options to install a 50amp plug to support and electric vehicle charger. He was very responsive and carefully listened to all of my questions and advised on the best way to proceed. Once I decided how to proceed, Danny was quick to accommodate my schedule and install my EV charger. The install looked great! The price was very reasonable compared to other estimates I received. In addition, Danny moved some circuits around to make space for a future appliance I plan to install. Finally, Danny reduced the price by $50 at the end of the project because he did not need to install one item that was originally planned. We need more honest and knowledgeable electricians like him.

Posted by Christopher L. on 07/03/2021 If I could give him higher than 5 stars I would. This guy know AC work! I hired someone else previously, but his diagnosis just didn't make sense (and turned out to be incorrect and extremely pricy). I found James Hertzel and a solid five star review, with tons of happy people are a great sign. He worked his butt off, testing everything, to finally figure out my very difficult system problem. In my 20+ years of using HVAC repair people he blows them all out of the water in skill. Thanks James, Chris
