"The Hague Team are experts. Would hire them again. Evaluated my need in 20 minutes or less, then set up a new Water softener install for the next morning. New WS installed in 2.5 hours and Hague loaded the solar salt, and explained every procedure. They help me with making Notes for my reference guide."

"Have a whole home water filter (Aquasana) that was already installed. Was happy to find an outfit that was comfortable working with a system they didn't install. I was really impressed with Hague. Herminio arrived right on time and quickly understood what he had to do. He quickly and carefully got the new water softening tanks primed, flushed, and installed. He took care to check for leaks. Will definitely hire Hague again."

"If you have a water softener or filtration project, I highly recommend Orbit Energy & Power. I had a very favorable experience with the company . Scott Cullin, the sales tech was very accommodating with scheduling our initial appointment. He was on time, asked about our project scope, performed his water tests and made a recommendation based on the findings. He was not high pressure at all. I advised that I was getting competitive proposals and it would be a few days before I made a decision. Orbit's equipment is the most efficient, seems to be the best quality, and quite frankly had the best warranties. The installation went well. The installer removed old equipment and installed the new softener and filtration kit. He was in and out within the 3 hour time window specified. He answered all the questions I had for him during the installation. Once everything was done and cleaned up, he went through the operation with me, explaining how everything worked and what things to keep an eye on. Very good experience. I will definitely use them again"
