I hired Green Horizon to change out my air conditioner, and to install a high efficiency hot water system, as well. I am a mechanical engineer, so I'm probably a bit more discerning about different products and methods than the average consumer. I was very impressed with Aaron's knowledge, and the overall quality of the work. Frankly, the system they installed is better than any residential work I've seen. They use methods that you usually see only in commercial work, and the result is a comfortable and efficient system for a very good price.

I was very pleased with Green Horizon, and have nothing negative to list. I found them by blind luck, looking for an HVAC company that was close to my home. I'm certainly glad that I did. They more than deliver on what a user should be looking for. The quality versus the cost is worth well above what you pay in the end. They even helped me with the paperwork for my energy rebate. I recommend them highly.
