How efficient thinking adds up to big savings.

Heating and cooling can account for more than half of your home’s total utility bill.* So when looking for ways to cut your energy costs, be sure to think about a high-efficiency system. How do you know if a heating or cooling system is efficient? Take a look at the yellow-and-black EnergyGuide label, which displays efficiency ratings for the product.

Heating Efficiency

Furnaces are rated by the Annual Fuel Utilization Efficiency (AFUE) ratio, which is the percent of heat produced for every dollar of fuel consumed. AFUE works a lot like the miles-per-gallon rating on your car—the higher the rating, the lower your fuel costs.

Cooling Efficiency

The measure for the efficiency of air conditioners and heat pumps is the Seasonal Energy Efficiency Ratio (SEER), which compares cooling output to electrical consumption over a range of temperatures. The higher the SEER, the less the unit will cost to operate.

Load Calculation Analysis

WrightsoftOne of the most common mistakes made in the heating and cooling industry is miscalculating the proper sized unit for the space required to heat and cool the home. Hallways, unusual closet spaces, and office nooks are often not considered when calculating the proper weight and capacity for heat and air conditioning needs.

Performing a load calculation is the single most important factor when designing a heating and cooling system. Installing a system which provides the correct capacity is vital to realize the maximum efficiency of your new system.

Installing a system that is undersized will require the system to run continually, struggling to meet the temperature set point. The consequence of this is extremely high power costs and an uncomfortable environment.

An over sized system will satisfy the temperature setting quickly then cycle off. This does not allow the system to operate long enough to effectively remove the humidity from the home and will require the system to cycle excessively during the day, driving up electricity bills.

The consequences of over or under sizing equipment is increased operating costs and unexpected repair costs.

Charlotte Comfort Systems uses the unique and dynamic Wrightsoft Software System to eliminate the guesswork about your home’s heat and A/C specifications. This software allows Charlotte Comfort Systems to combine load calculation, equipment sizing, duct sizing, geothermal design and cost calculation for determining the proper fit so that you have the most efficient unit for your home.

**Air conditioner calculations are based on every $100 spent to cool a home using a 3-ton, 10-SEER unit. The criteria base for furnaces is a 60% AFUE unit, with a 50,000-Btuh heating load. Fuel rates and heating hours are factored into the calculation upon selection of a state or region. If a state is not selected, the calculator defaults to the US national average for fuel and electricity consumption. Actual costs and savings will vary depending on weather conditions, usage, location and local utility rates. This information is intended as an example for comparison purposes only.
