Charles Townsend

Very thorough and efficient experience! Had three separate experts come to our newly purchased house to assess the hvac, plumbing and electrical. Very pleased with their communication, follow ups and professionalism

I had a great experience with Zach Grant when you came to do my annual boiler system inspection. He was thorough, attentive and explained everything he did thoroughly. He answered a lot of additional questions I had on the system concerning how best to inspect and maintain it throughout the year myself. Zach did a major repair to the system last spring that completely fixed all the problems I was having. My boiler has operated perfectly since he fixed it. I would definitely recommend him and Welzig.

We had an issue with our mini-split heater not working well. Scheduling with Welzig was easy, they send a reminder email and a text right before the technician arrives. The technician, Zach, was super friendly and professional and had our heater unit fixed in no time. He explained the issue and provided a quote for the repair before starting. We will definitely use Welzig again in the future.

Our repair expert James was very knowledgable and friendly. He was also very helpful, honest, and kind. Fortunately, we had what turned out to be a very simple problem and he resolved it for us quickly. We were without heat, and Welzig responded very promptly, we only had to wait about 3 hours for service after placing the initial call. We are very grateful to Welzig and highly recommend them.

Easy to deal with, easy to schedule, prices were clear, and everything happened as they said it would. James, the technician, was a delight. He was on time, and polite, and friendly, and clearly loves his work. He communicated clearly so I could follow along with what needed to happen. I felt completely safe with a guy I had never met before in my house. (And they have great coupons.)
