We hired Building Efficiency to convert our failed gas water heater to an energy-efficient electric heat pump water heater. David Hamburger did the site review/estimating; and office manager, Mae Adams, handled the admin and rebates. We all worked very well together. Building Efficiency also coordinated nicely with an electrical company doing other upgrades in our home to locate a new 220V/240V line to the site. The Building Efficiency installation team was also very professional and swift in their installation, which required moving/reinstalling another unit’s adjacent water heater and providing a new/expanded base pan for both tanks. David also worked with us to find the most efficient heat pump that would fit into the area’s physical constraints. The City permit inspector was very complimentary of the final installation, which was nice confirmation of a job well done. We are very happy with the results of our new energy-efficient, electric-heat-pump, water heater. The BAYREN rebate just arrived today, and the very important conversion from gas to electric was well worth it. Thank you Building Efficiency!
