"I originally found out about this company, SONERGY USA, as I had to have the inverters replaced for an existing solar panel setup I had. The folks I interacted with were amazing and extremely professional. They were able to take care of the repairs right away, but more importantly they fixed some items the original solar panel installer did not do properly. I was so impressed by the work SONERGY USA did with the repairs that I eventually moved forward to get additional panels installed and even a battery installed. Again SONERGY USA did not disappoint. Everything was professional and done properly. Most of all the communication with the team was amazing where I did not have to babysit them or waste time off from work in order to get the work completed. SONERGY USA stuck to the timeline as well. which I greatly appreciated."

"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"
