I can't recommend Jonas enough. We were fortunate to have Yohannes come to service our AC unit. He did such an amazing job. He was quick, efficient, kind, compassionate, and extremely well-versed in his field. We had previously had a different HVAC "specialist" "service" our unit. The previous "technician" was completely inept, overcharged me, and left me without operational HVAC. Yohannes did the exact opposite. Our senior dogs were really struggling in the heat of our house and now can be comfortable and happy with the cool air blowing once again. Thank you, Jonas Energy Solutions. And a huge thank you to Yohannes Gebrezgi who did the best job for our family. He's the best!

Jonas's service technician Cliff has been to our home twice within a year to maintain our Mitsubishi mini-splits. He is professionally trained to work on these units, his work area is always neat, he's available for questions, he wears a mask at our request, and overall does a great job keeping our units running smoothly and is a nice person.

We had a great experience with Jonas today. We had our system inspected by their technician Yohanis. He was polite, respectful and paid attention to my concerns. This inspection didn't turn up much, but he did find a disconnected run of ducting under the house. He repaired the disconnection and, of course, the air is blowing much better in the affected rooms. The price was right and service was great. Yohanis even read a short story to my youngest. Thank you Jonas. They will be my first HVAC company to call in the future.

Jonas has been consistently great to work with! Our heat pump mini split system that Jonas installed has been rock solid. We are working with them again on a rooftop solar installation. Great people, efficient, and dependable! Thank you Jonas!
