"My water heater tank stopped working so I decided to convert to a tankless system. Chad and George were who I worked with. I had a great experience with both of them. I was very pleased with their knowledge, work, communication and help. I would highly recommend them to other house owners. "

"My water heater started leaking and my hot water was gone. I got an outrageous quote from a local plumber who was too busy too replace it. Thankfully I was able to contact George, and he was able to come the same day to replace it. Not to mention his prices were much affordable. I would highly recommend anyone who needs their water heater serviced!"

"Cody was prompt with his quote and kept in contact with me constantly. Our project was able to start weeks ahead of schedule and was completed on time and on budget. Multiple crews worked on our home across a week and a half. Each individual was professional and was more than willing to spend time explaining each step of the process. They cleaned up each day leaving the house in almost better shape than when they started. They also worked with us around accommodating our animals. Cody was able to adjust and respond quickly to change requests we had during the project and we could not be happier with the result. Post install Cody has been great taking our calls for questions on the new system and helping us learn usage of the systems. He even walked me through an easy change to the tankless hot water heater spending a good hour on the phone with me. Overall Cody and the team at SeaTown electric heating and air have been wonderful to work with and have exceeded our expectations with our hvac and hot water tank replacement. We will be using them again for future projects."

"Rob came out to review our existing system and helped us figure out what kind and brand of heat pump would work best with our system. He was very patient and informative, and answered all our questions without any pressure or up-sells (we had quotes from five providers). We signed the contract and payed our deposit in June 2021, but unfortunately global supply chain issues delayed the parts being received. Day & Nite were communicative of the issue and offered several alternatives, including a refund of the deposit. We opted to wait for the parts. It took four months, but the techs (lead by Jeff B) were fantastic and very accommodating in how we wanted piping and wiring routed. We are very pleased with how it's turned out and loved working with a local (and family owned!) company! Our gas water heater is due for replacement soon, and we'll be coming back to Day & Nite for that!"

"Great. I received 3 bids and Drain Pro's was the most competitive and thorough. We scheduled a date, and installation was done in a day. They removed my old electric water heater and were tidy and very professional. I paid by check as they left. Now I will have to install an electrical outlet next to the heater but meanwhile, it's on an extension cord... Looking forward to 24-hour hot water, and a lower electric bill!"

"Purchased an Angie's List deal for a hot water heater for $799. However, when the installer arrived, my installation required a direct-vent hot water heater. That was provided by the company at a later date for $1799, a quite reasonable price. I would recommend them, and use the company again."
