Buyer Beware! At Mountaineer Heating & Cooling, we partner with several manufacturers to make available a product line that will accurately meet each application, of which there are many. Many of these manufacturers, including Trane, Water Furnace, Mitsubishi Electric, Aprilaire, and Honeywell (for specific products), prohibit online sales in order to ensure the products are installed by authorized contractors who are individually trained for each product. Any purchase made from web-only retailers or from internet-only sites OR any product where a model or serial number has been removed, replaced or altered in any way WILL NOT BE COVERED BY A MANUFACTURERS WARRANTY. Remember, a digital or paper copy of a generic warranty statement will not be satisfactory for warranty claims, as each product has a serial number that must be registered with the manufacturer by a licensed and authorized installer. MHC registers the warranty on all products purchased and installed and will provide customers with a copy of the original written warranty.

As a general practice, MHC will only install the products we provide.  Products purchased from a source other than a licensed, authorized contractor are often previous generation, reproductions, remanufactured, discontinued or in less than “new in box” condition and do not carry a manufacturer’s warranty.  This policy applies only to new installs, as our Service Department will gladly provide diagnostics, repairs, and tune-ups on all brands of equipment, regardless of who installed it.

Unit of measurement for determining cooling capacity. One ton equals 12,000 Btuh.

Heating Seasonal Performance Factor. A measure of heat pump heating efficiency. The higher the rating, the more efficient the heat pump. The US government’s established minimum HSPF rating for furnaces is 6.8%.

Seasonal Energy Efficiency Ratio. A measure of cooling efficiency for air conditioners. The higher the SEER, the more energy efficient the unit. The government’s minimum SEER rating is 10.

A combination heat pump or air conditioner with indoor components such as a furnace or blower coil. Split systems should be matched for optimum efficiency.

Annual Fuel Utilization Efficiency. A measure of a furnace’s heating efficiency. The higher the AFUE percentage, the more efficient the product. The US government’s established minimum AFUE rating for furnaces is 78%.
