We needed new heating that would be more efficient than the combination oil-and-wood-fueled system we had been using for 14 years, and we got one proposal from another installer that was way beyond our budget. Then we heard about EnergyStarDave, and we're sure glad we did. Our total cost for energy is now approximately one-third of what it would have been, and we now also have the benefit of air conditioning, which we never had before. This was without a doubt the best home improvement investment we have made since purchasing our home. Thanks, Dave!

When I met Dave from EnergyStarDave, I was impressed with both his knowledge and his professionalism. The mini split system has outperformed all my expectations. We're now comfortable all year round, with the added benefit of saving money. I have had homes with central air before and they do not hold a candle to this system - and it's so quiet you can't even tell it's running. Dave is not only reliable but you can tell the passion he has for his work

EnergyStarDave is fantastic! He's very professional and really cares about his customers and the work that he performs. Dave took the time to explain all our heating and cooling options. He had to work around a very poor attic design by the builder and was very creative at coming up with a solution for maximum energy efficiency. He also has a great group of people working for him - dedicated, friendly, and hard-working! I definitely recommend EnergyStarDave!

I hired Dave to take a look at my boiler and indirect water heater that were not working properly. I had called several plumbers before, but none of them could diagnose the problem correctly. A couple of them recommended replacing my boiler (only 10 years old), which would have cost me $15-20K. Then Dave came over, ran a few tests, and told me there was nothing at all wrong with the boiler, and that the problem was in the water heater. He switched it out for me the very next day, for under $1,000. Now everything is running smoothly. Very professional, great communication. Will hire again!

We couldn't have had a better experience working with Dave and his crew. Converting our 1890s farmhouse to a year-round residence was a significant challenge in an area of the Catskills that gets down to 20 below. Dave engineered a system specific to our needs that has kept us toasty all winter and kept our heating costs down. It's efficient, totally silent, and we love the fact that we can control it from our smartphones. Thank you, Dave!

Dave did a great job replacing my old inefficient oil furnace with a smartphone-controlled Mitsubishi ductless mini split system that both heats and cools my home. The system works great and lowered my heating bill substantially. Dave was very patient and knowledgeable through the entire process of helping me choose a system, figuring out the most efficient and aesthetic way to install it, and then returning promptly when small issues arose. Highly recommended!
