Recommended Customer Reviews

Great service. Showed up on time and did the maintenance checkup quickly and efficiently.

Best customer service ive ever received from a home repair man in any capacity. Sam is awesome! Would use them again and again in a heartbeat. Def. the best company in Houston to repair/replace/diagnose your water heater!!

Thank you Tankless Hot Water Guys! You guys where very professional and the installation was fast! I look forward to having constant HOT water to doing dishes, laundry and hot showers. It's a pretty machine. Thanks again.

From the start, they were great. Very accommodating: I called on a Sat AM after having been told by a few other local plumbing companies that I had to wait over 2 weeks to have someone service my tankless water heater. Brittany (sp?) was incredibly helpful and resourceful over the phone and Brian arrived at the appointed time (within 2 hours), efficiently cleaned/flushed my heater and took time to answer all of my questions. Overall very positive and professional experience. Problem solved, great experience.

i bought a house. it had an old rusty hot water heater. i happen to be driving on 19th street and saw the HOT WATER GUYS wrapped vehicle.....and i needed a tankless hot water heater! fate! i called immediately and set up an appointment. within the week, i had a new tankless hot water heater. thanks! they were nice. they were dependable. they were in constant contact with me throughout the entire process. even afterwards. thanks!!

Amazing customer service from beginning to end. Our hot water froze overnight & the kind woman I spoke to was able to squeeze us in on a full day. When Sam showed up right on time, he found that the situation had actually resolved itself & the hot water was running again...He gave me some tips on how to solve the problem in the future & didn't even charge us for the trip. Truly a pleasure to find such a top notch & honest company! And thank you Sam for not making me feel silly wasting your time & for your expert advice!

Brittany and Brian took care of my problem with a Rinnai tankless as quick as the part could arrive, when another firm let me go all weekend without hot water. Great, knowledgeable work, and very kind and responsive on the phone. Very reasonable on price and quick when it's an hourly job!!

Unreliable and unprofessional - even the lady that answers the phone is rude. Our hot water hasn't been working for over a week now. We have called multiple times and have been pretty patient with hearing back - but never get a call back. Used to think it was a great company, but then I realized they don't really care about their customers (or are too busy)

Excellent service, reliable and honest..a rarity nowadays! You won't be disappointed!!

I had a defective Honeywell Gas Valve replaced by the Hot Water Guys under warranty from State Water Heaters on Oct 1. After the installation repair, my wife occasionally noticed the smell of the sulfur from the natural gas when she goes in the garage. On Oct 19 morning I was overwhelmed with the smell as I left for work. I did the soapy water test on all the connections around the water heater. The brass fitting that connects the pilot tubing to the Honeywell controller was loose. It took a 1/4 turn to tighten it. I contacted the Hot Water Guys asking for a partial refund. They have refunded the total cost of the service call and have made an adjustment to their employee roster.
