Bill Day was easily the most knowledgeable and personable of the companies we had evaluate our home HVAC needs. We are pleased with our Carrier system primarily because Bill was able to educate us on what our installation and product options were and so far the Carrier system has delivered to the expectations he set. William Day is an highly professional organization and I will continue to use and recommend them to others - congratulations and thank you Carrier!
