"This is the second property I’ve gone solar with, and the difference was night and day. My previous company fell short — Aduu Solar is truly the best of the best. Professional from start to finish, with fair, transparent pricing."

"Jefre from Sonergy was fantastic from the very beginning. He responded immediately from my job request on Angi, and agreed to evaluate my solar panel system the next day. He was able to determine the problem immediately after troubleshooting my system and he followed through by ordering and installing the new inverter. He was very conscientious and paid great attention in performing the job and clearly explaining the repair process as well as the monitoring process. He was very knowledgeable with my solar panel system, such that he helped me to transfer my system monitoring to his company Sonergy. I feel very happy to know that my solar panel system will be properly monitored and maintained by Sonergy. I received phenomenal customer service from this customer and I would highly recommend and rate them 5 . out of 5 stars."

"I emailed Day and Night Plumber after my old water heater started shooting water out the front panel and within 10 minutes I got a phone call from them with an appointment for an estimate with Marin. The quote was very reasonable and after I supplied the Hybrid Water Heater, Marin was able to come install it on Sunday. He was extremely knowledgeable, efficient, and hard working. He finished everything, cleaned up the area, hauled away my old water heater, and showed me how everything worked. He even gave me a military discount and 12 month warranty on labor. If you need a plumber for anything, give Day and Night Plumber a call, they will give you top notch service for a reasonable price."

"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!"
