Frequently Asked Questions

Can I purchase products online?
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.
Will you install products that I purchase elsewhere?
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.
In relation to HVAC capacities, what is a 'ton'?
Unit of measurement for determining cooling capacity. One ton equals 12,000 Btuh.
What does a heat exchanger do in a furnace?
Located in the furnace, the heat exchanger transfers heat to the surrounding air, which is then pumped throughout the home.
What does HSPF stand for?
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%.
What does the acronym SEER mean?
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.
What is a split system for HVAC?
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.
What is AFUE and what does it measure?
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%.
What is an air handler?
The indoor part of a central air conditioning or heat pump system that moves cooled or heated air throughout the ductwork of your home. An air handler is usually a furnace or a blower coil.
What is an evaporator coil and where is it located?
The part of a heat pump or air conditioning system that is located inside the house in the air handler. It is here that the refrigerant evaporates as it absorbs heat from the air that passes over the coil.
What is CO?
Carbon monoxide is an odorless, poisonous, flammable gas produced when carbon burns with insufficient air and is deadly to humans.
What is HVAC zoning?
The ability to partition a home into various zones, thereby providing the opportunity to control comfort levels in each zone.
