I woke up this morning to find hot water pouring from a pipe connected to my Viessmann boiler - inches of hot water had filled my garage. A friend recommended David and I called him at 8am - David was here within the hour, repaired the failed parts, helped me understand how the mechanism works and what to do in emergencies, and had the entire issue resolved by 11am. Outstanding professionalism and knowledge - incredibly fair pricing. Highly recommend! Will be hiring him to install two heat pumps for me now too!

David is very professional and knowledgeable. He explained my options in a way could understand. During the two day installation I Found David, Andrew and Adam very respectful, friendly and professional. In addition to installing a new heating system they also repair Ike’s a leaky shower that was installed incorrectly. The shower runs like a charm now! I highly recommend Warm Waters and will be using them again for other heating and plumbing needs!

David responded immediately after I contacted him when my steam boiler stopped working. He came out and confirmed that a new boiler was needed given the age of existing boiler and lack of replacement parts. I got other quotes but all had supply issues that predicted a wait of 2 weeks or more. David found two great options and once I made the choice, the boiler was installed within 48 hours. He picked the new boiler up from the distributor with his own trailer in a raging snowstorm and we had great heat later that day. Amazing response and quality service!

Warm Waters installed a new heat pump at my house at the beginning of summer. David and his team spent 4 full days to get the heat pump fully operational, paying attention to all the small details and consulting with me when decisions had to be made. David is very knowledgeable about how to properly install and maintain heat pumps - we were lucky to find him! The house is now perfectly air conditioned (no hot/cold spots). I would highly recommend!

I recently had Dave and his crew install a mini-split heat pump in my small apartment. I got several quotes and while his wasn't the cheapest quote their pricing was competitive. I went with Dave because he was very friendly and answered my questions, and he was a good communicator throughout the process (this goes a very long way!). His crew was very respectful (wore masks, used drop cloths, etc.) throughout the full day install, and I'm happy with my new unit. I'm finally going to be warm this winter and cool next summer!

I needed a new heating system for my home in Durham for 2018/2019 heating season. I contacted three firms. Two of them took forever, like several weeks, to even deliver a proposal. Warm waters came out within a few days, and was available to install the next week, in October 2018. Dave and Liz were professional, punctual, and finished the job on time. A few months later, we are very, very pleased with our new heating system. Warm Waters was not the cheapest estimate, but they worked very hard, and installed a higher grade system than the others. I would much rather pay more for a better system
