Our technician was Wesley. He did a good job and was a pleasure to have around. Fun guy to talk to, and the new water heater works great.
The service technician Wesley was amazing he was knowledgeable experienced answered all of our questions and installed the water heater
Perfectly. He is a true asset to Water Heaters Only, and will recommend them to all my friends and family.
Thank you
The estimate was literally in the middle of the "it will cost between X" amount! I don't think I've ever had an estimate so on the nose.
Secondly, the technician they sent, Wesley was communicative, polite, professional, and most importantly to me, he explained things clearly - from bringing our installation up to code, to showing me the how-to of my water heater.
I would highly recommend Water Heaters Only!
Great responsiveness! Great service!
Thank you very much Wesley and Shaun.
Lucas from Water Heaters Only called me about 20 minutes before arriving and well with in the time window given. He arrived on time, explained what steps he would follow and asked if I had any questions. He started in and kept busy the entire time. When he finished he reviewed, lighting process, draining as need and how to adjust the temperature. He then asked if he needed to explain anything else again or if I had any questions.
I felt very comfortable through the whole process. I would recommend Lucas and Water Heaters Only to anyone needing Water Heater repair or replacement.
Professional, punctual and very thorough.
Showed me how my new water heater works.
He is a great asset to your company.
