For as long as humans have sought shelter, they’ve found new ways to keep them warm, from fires in caves, wood stoves in our kitchens and coal fireplaces in our living rooms. Since the 19th century when radiators and riveted-steel furnaces were first invented for the home, keeping our homes cozy has only grown more efficient, with a reliable fuel options. Today the 2009 Residential Energy Consumption Survey reports almost 85% of US homes are heated with natural gas or electricity, and more than 10% use heating oil or propane.
Not only do modern furnaces heat the home, they are a crucial part of the overall HVAC system. They can be used to blow air cooled by the air conditioner through the duct work, and to circulate returned air back through the system. Therefore it’s important to have a quality furnace at any time of year, and for your furnace to be sized correctly for your home. As with air conditioning units, too large a furnace will cause the unit to constantly switch on and off, wasting energy and reducing efficiency. Too small a furnace won’t be able to keep up with the amount of air in your home that needs heating or circulation, frustrating your system efficiency.
At Hiwassee Chase, we are proud to offer Carrier brand gas and oil furnaces that are highly rated for energy efficiency and long lifespan. Like the SEER ranking for air conditioners, furnaces are rated on efficiency using the AFUE, or Annual Fuel Utilization Efficiency. AFUE is listed in terms of percentages. For example, an AFUE of 90 means that 90% of the fuel used warms your home, while only 10% is wasted as exhaust. Carrier’s current line of residential gas furnaces start at a minimum of AFUE 80 and go up to 98. Their oil furnaces start at an AFUE of 80 and some models reach up to 86.6.
A furnace with a higher AFUE rating will cost more up front, but will quickly pay for itself in monthly utility bills. By consulting with a quality HVAC service like Hiwassee Chase, you can be confident in getting your money’s worth from your furnace. You’ll know it’s the right size and high efficiency, keeping your utility bill as lower than with your old unit. Enjoy a comfortable home year round with a quality furnace and trusted installation by Hiwassee Chase!
