Real Reviews from Real Houston Homeowners
Don't take our word for it — here's what our customers have to say about working with Affinity Hot Water Technology.
“Affinity was great to work with. I called on Thursday and they came that day. They assessed our need for a tankless water heater and gave us a reasonable quote. We agreed and they scheduled us for Monday. They were very communicative and showed up right on time. The installation went smoothly and they showed us how the unit works and left care and maintenance instructions. I highly recommend them.”
“David was incredibly helpful from start to finish. His years of experience in the industry really show — he's professional, knowledgeable, and someone you can trust. The installation turned out perfect, our water is officially cleaner and softer, and the kids said, "it's like hugging a pillow!"”
“Affinity Hot Water Technology is fantastic. Knowledgeable team. Answered all my questions. Scheduling was easy and service was completed in a timely manner. I had a tankless hot water heater flush done, a whole house water filtration system installed, and a reverse osmosis under the sink system installed. I am so glad that Affinity was recommended to me. It's nice to do business with a dependable and knowledgeable company. Would definitely recommend to others. I will also continue to use Affinity for future needs.”
“I recently had a tankless hot water heater installed by Affinity Hot Water Technology, and the experience from start to finish was outstanding. This company — and the people I worked with — would rank in my top three throughout 40 years of homeownership. Their competitive pricing, expertise, quality installation, and integrity are a testament to how business should be done. David and Jennifer at Affinity lived up to everything I had heard. Thank you for standing by your Word.”
