"I was going to have some work done to my basement and needed the water heater moved. It was time replace the heater so I asked Northern if they could remove the heater and install the new one the next day. They were fine with that. The workers were very professional and friendly. The installer took the time to explain all the controls and maintenance. Very pleased with results"

"We had them replace plumbing fixtures in our bathroom remodel and install in-line water heater to provide point of use hot water to a distant bathroom from our water heater. In addition, they replaced a deteriorating concrete laundry tub and replaced a shut-off valve for an outdoor water faucet that was leaking."

"I would rate the service by Pure Mechanical with more than 5 stars if I was allowed! Kelly and Chris were very responsive throughout the process. They provided a very competitive quote quickly after I provided some photos of the project. I appreciated their willingness to share knowledge and detail about the pros/cons of different types of water heaters and helped me make the final decision. For the service appointment, Kelly and Chris were right on time, made sure to keep the house and work area clean, and completed the installation in an efficient and timely manner. During and after installing the water heater, both Kelly and Chris shared information about how to better maintain the water heater to extend its service life (information the plumber that installed our prior water heater had not shared). All in all, it was a great experience working with Kelly and Chris from Pure Mechanical!"

"Know that if you do the tankless water heater there needs an outlet near by to power the digital display and condensation pump. ISO know they will send an electrician and that cost is separate"
