"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!"

"They did a great job, we had some sewer replacement work done and a tankless installed. We love the tankless and haven’t had a single issue with our sewer since. It was so worth it, and they were quick and efficient!"

Customers say: Super punctual

"Jason and Harry arrived early to the house (I was late!). They came in, listened to the problem, and got right to work. They were efficient and worked great as a team, completing the repair in just about an hour. No more leaks! They cleaned up everything and were very friendly, answering any questions I had. Would definitely use them again.

They have done commercial and residential projects for us handling all of our plumbing and gas piping needs. Jeff and his team are very experienced and extremely knowledgeable in all the services they provide. I would highly recommend them to anyone needing plumbing or gas piping services!! They do great work at a very competitive price."

"We had received a quote from a different big name company for $2000 MORE than what Hot Water Heater Company quoted. Hot Water Heater Company sent their technician, Matt. He came out, gave us a price, went and got the equipment, and installed it - all within less than 4 hours. Great price, great service...and we have hot water!!"
