Have you ever wondered just how much money you could save by being efficient…
Lennox has a wonderful calculator on their website – Energy Savings Calculator
Click on this calculator, choose Heating or Cooling, Select your Area (Canada is at the bottom – save the best for last 😉 ), then choose the efficiency of the appliance. This is what you’re looking for (this is from the Lennox link above).
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.
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.
The results this calculator shows you is savings in 5 years. You will see a large savings for your Heating System, the Air Conditioning Systems will not provide you with a huge savings – however it is your comfort level which is the main reason for upgrading your AC, having a more efficient system which is properly sized to your home and system will run much more efficient and if you upgrade to a more efficient system it will be quieter as well – which again is your comfort!
