    I contacted Water Heaters Only, Inc for installation of the brand-new American Standard GN50T1-3-6NAT water heater, they sent Lucas. He is professional and courteous, and he got the job done within 2 hours, here was the scope of work: Remove and install the water heater with new hot and cold water flex lines, insulation wrap, bonding clamps/wire, horizontal wall blocks, and earthquake strap unit to code. Install 5 feet of T&P line, and reattach the existing venting. Modify hot and cold, replace broken shutoff valve. His work is impeccable, and he has the patience to clearly explain how to safely operate this unit. A well-deserved 5-star review :)

    The service person who came out (Wesley) to replace the water heater was pleasant, knowledgeable and professional. He got the work done within the time period he stated, cleaned up and had everything back to normal. I would definitely recommend this company!

    Our water heater started to leak and no hot water in cold. Called Water Heater’s inc and was able to get Dan scheduled to check and quote. We ended up getting the work done and hot water flowing back again. Super service
