Josh and Jason moved our furnace to our attic and replaced all of our ductwork with more efficient ducting. The furnace and AC are now 20% more efficient and the force of air increase is noticeable. They were the best price and arrived when they said they would and kept in constant contact. I would not hesitate to recommend them. I will have them do my solar as well.

We used Hans Energy Systems Construction Mechanical at work and were very impressed by the solid work, professionalism, and useful suggestions for our heating & air conditioning. I also used them also for a plumbing job at home and am very pleased with their work. I would recommend them highly!

Josh did an outstanding job replacing our furnace and upgrading our outdated system. He performed excellent work and an economical price. We had moved out of state and needed the work done on our house for sale. He was very accommodating with the payment plan. I would highly recommend him for any HVAC work!

Exceptional experience with this company.Will recommend to everyone. Josh was very quick in coming out for an estimate and set up the AC install the next week. His guys even stayed at my house longer than planned to help me when the thermostat I had wouldn’t connect to the unit. I had one minor issue after the install and Josh immediately sent out his brother (and installer) to fix it! So happy these guys were recommended to me. They really go above and beyond to do the job right and take care of their customers.

Josh did a great job on a 10kW system for our Poway home. I did quite a bit of research and Josh was able to find the panels I wanted at a better than expected price. And I doubt that large installers would have completed the job or connected the system to SDGE as quickly.

Josh is one of the good guys. Hooked me up with air conditioning about 5 years ago. Great price! Last year air went out in the middle of the heat wave and he came out the same day and fixed in about 10 minutes with no charge. He just installed our solar a couple of months ago and again great price and quality work.

Hans Energy Systems installed our solar panels and we couldn’t be happier: great customer service, competitive price, and all the work was done quickly with minimal disruption. Highly recommend!

Great! Solar Systems and such a nice and caring person.

Excellent service and communication! Expertly walked us through the entire process from equipment purchase, to installation and monitoring. We highly recommend Josh and Jacob.

Josh is a professional. He was easy to work with and communicated with me as each step of solar was installed. His pricing is very fair and makes the process smooth.

Hans Energy Systems just removed our old rooftop HVAC unit and replaced it with a Daikin mini split with two indoor units. Josh and his crew were on time and did a nice, clean install. They left the building clean and tidy. The new units are working great. We are very pleased with the experience.

Due to flooding we needed to remove solar equipment and install a new HVAC unit in our house. As usual, Josh was there to help us out. Very professional, knowledgeable, and personable.
