"Amazing service from Hans Energy Systems. We got our water bill and the amount had tripled. Contacted them in the afternoon and the tech was out the next morning. Got under the house and found the leak. Got it fixed and cost less then half of what our water bill was. Provided us with photos of what they found. Couldn’t be happier with the service and price. Great, honest service at a more than fair price."

"We needed my ducts replaced during a condo renovation (we raised the ceilings in the bathrooms) and I wanted to add a booster as the airflow to the bedrooms was weak and not cooling correctly. Apparently there is a blower speed setting in the system that he was able to turn up during our 1st visit. Said I didn't need a booster now...saved me some $$ with that suggestion! Came back the next week and redid all my ducts, strapped them correctly and got me back running and ready for drywall. Good work and nice guys Josh and his son Jacob on the job. They also installed a new EcoBee thermostat for me."

"Hans Energy did an outstanding job installing mini splits in every room. They found the most discreet and efficient way to complete the work, seamlessly concealing all hardware. The team was extremely neat and very professional.."

"Josh installed our 2nd set of solar panels (I wish we had use Hans Energy for the initial set), the installation was quick and the system works great as we needed more panels to charge our electric vehicles. He correctly size the number of panels we needed for our usage and our electric bills are hardly anything or often a credit. He was more affordable than other solar companies we got bids from."

"Josh and his team did a great job installing a Tesla powerwall."

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