"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!"

"Previous owner used non-heat rated PVC piping on the water heater. Entire system was almost a decade old so decided to change out the heater at the same time. After giving the owner a good description of the problem he was able to give me a quote over the phone ($1950 + tax). I decided to let them come out and access the job before agreeing. They arrived on time and after a quick assessment the lead plumber quoted me a higher price but after consulting the owner they agreed to do the job for the original price quoted. Mike and John worked quick and efficiently. They were polite & professional and had the entire job complete and work site cleaned in 3-hours. Over all quick and painless process, would use their service again."

"I have used this plumber for over 4 years now - they respond immediately to any concern, are the most honest and fair people out there! Anything from simple drain clear, or water heater install, to a side sewer and complete DADU plumbing installation…they do it all, and with great communication! I pass their name and number to anyone who is looking for an honest and reliable plumber!"

"Bryce and Eva were fantastic. I had a pipe rupture. I was in a panic. They walked me through the most effective way to shut off the water. They didnâ t provide the service to repair everything the next day. I asked if he could repair a toilet while he was here. He graciously took care of that as well. I could not ask for more."

"Dominick was on time explained what he was going to repair did a great job explained and wrote up estimate for replacing a new water heater fast service, polite technician explained my options for new water heater to be replaced in Jan great guy will hire him in Jan to replace the hot water heater"

"Brian was on time and super knowledgeable for dealing with my tankless hot water heater. He got right to work and dealt with the problem and helped me establish a paper trail with the manufacture in case of any future warranty concerns."

"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."
