Heating & Furnace Replacement

Heating System Replacement, Heating Installation & Furnace Replacement

Replacing your old furnace with a new, more efficient model can combat volatile energy prices, reducing your heating costs by up to 45%. Advancements in heating technology have led to systems that pollute less, boost comfort and last longer. A twenty to thirty-year-old furnace typically has an AFUE of about 65%. The lowest efficiency allowed by law for new gas models is 78%, and there are numerous options that achieve 98%, for near-total efficiency.
