Saving Energy and Money
The total cost of heating and cooling
the average U.S. home is about $2,000 and that price is rising. When you have got
an energy efficient air conditioning or heating system, you do not have to be
part of that statistic. That is why it pays to calculate how much energy a new
home comfort system can save you.
Learn how the higher efficiencies of todays heating and cooling
equipment translate into lower utility bills.
Understanding Energy Rating Systems
To help you make informed decisions
about how to save energy, several rating systems have been developed.
The Seasonal Energy Efficiency Ratio
(SEER) rating
measures the efficiency of central air conditioners or heat pump usage over a
theoretical cooling season.
It's a simple ratio of the amount of cooling provided by the air conditioner, as measured in BTUs with the amount of energy the central system consumes, measured in watts/hr. So if you see a system rated at 16 SEER, that actually means it produces 16 BTUs per watt-hour.
But remember, a SEER number is theoretical. Your usage patterns, as well as proper equipment sizing and installation, will determine actual efficiency.

The Heating Seasonal Performance
Factor (HSPF)
measures a heat pumps energy efficiency over one heating season combined with
its SEER value over one cooling season. The HSPF formula is slightly more
complicated. But the HSPF rating uses BTU to calculate useful heating output
(including electric heat) divided by the total electricity energy heat pump
consumed (in watt/hr) during the heating season.
The Annual Fuel Utilization Efficiency (AFUE) measures average efficiency for furnaces, boilers and water heaters. This is a measure for a theoretical heating season, not including electricity.
For SEER, HSPF and AFUE, higher numbers indicate higher energy efficiency. These numbers are then used in two energy rating programs:
EnergyGuide label:
Manufacturers of heating and cooling equipment are required to display the
EnergyGuide label. This label estimates how much energy the equipment uses,
compares energy use of similar products, and gives approximate annual operating
costs. Your exact costs will depend on local utility rates and the type and
source of your energy.

Get the Right Size to Save the Most Money
In most homes, the heating and
cooling system is too big. Besides wasting energy, improper size can create
uneven temperatures, poor humidity control and maintenance problems over time.
Improper installation can reduce system efficiency by up to 30%. But properly sized ENERGY STAR qualified equipment can easily cut your annual energy bill by hundreds of dollars. Programmable thermostats, like the York Affinity Residential Communicating Control, can save you even more with improved energy savings, home comfort and peace of mind that your equipment is operating at peak efficiency.
