Mark and team installed a new tankless water heater for us. The job was completed extremely well, on time and at a very competitive price. I was very impressed with their communication and quality service, and would strongly recommend them for your HVAC needs. I will be using them again! Thank you.

Mark and his team were excellent throughout the whole process of replacing our failing gas heater tank with a new tankless system. Prompt, responsive, clean and professional from the first conversation to the final follow up call. Will definitely use House Depot again and would recommend them without hesitation.

Happy with the quality work Mark did to replace a Tankless Water Heater in our house with a new one, when our older one suddenly stopped working. House Depot was quick to respond, provide a quote and do the install within a couple of days, which was much appreciated as we were without hot water. Mark worked very hard on the job, and was thorough in all the work he did. I didn’t realize how much work goes into a Tankless install. Good, honest and straightforward. I would hire Mark again.
