    Customer Testimonial

              I could not find where we could give our testimony regarding our experience with Halco...so I'm putting it here...We have been customers of Halco for several years, always happy with service. In fact, the customer service is outstanding. We recently had an energy audit done by Will Graeper, he was very professional, explained everything in a simple, well understood manner. Our audit proved to be helpful, and because of the outcome, we are having the insulation blown under our manufactured home. Thank you Halco for your dependable, professional service.

Case Studies I've worked on:

Before and after photos from jobs I've worked on:
  • Air-Source Heat Pumps Installed in Hector, NY
    Before
    Air-Source Heat Pumps Installed in Hector, NY
    After

    This is one of two air-source heat pumps installed for a Hector, NY customer. The heat pumps installed in this home are ductless split systems that, like air conditioners, have compressors and coils that the can evaporate and condense refrigerant. Unlike air conditioners, they are designed so you can reverse the cooling cycle, and move heat from the outside to the inside of your home. Air-source heat pumps have become a popular retrofit system for households that have non-ducted heating systems in place. All noisy components are outside of the living space and the customer's windows remain unobstructed.

  • Ground Solar Mount in Trumansburg, NY
    Before
    Ground Solar Mount in Trumansburg, NY
    After

    This 5.5 kW solar electric system was installed for a customer in Trumansburg, NY. Comprised of 20 SolarWorld solar modules, this system is designed to generate 5,374 kWh per year with a CO2 emissions savings equivalent to approximately 3,980 pounds of coal burned. The end result of this project was simply stunning!

     

  • Crawl Space Insulation in King Ferry, NY
    Before
    Crawl Space Insulation in King Ferry, NY
    After

    After receiving a free home energy audit from Halco, this King Ferry, NY customer decided to take a step towards improving the energy efficiency of her home. Because the crawl space of the home wasn't properly insulated, the space was a major source of air infiltration and heat loss. Halco technicians insulated the crawl space walls and rim joist with closed-cell spray foam and also installed a CleanSpace vapor barrier to the floor. This newly sealed and insulated crawl space will help prevent mold and moisture problems, and will make the home more comfortable and energy efficient!
