Understanding AFUE-

What is AFUE? AFUE stands for Annual Fuel Utilization Efficiency. The energy efficiency of a furnace is measured by the AFUE rating. This does not include the electrical energy that is necessary to operate any controls, fans or pumps. A higher AFUE rating means greater energy efficiency. Simply put, how much heat generated by the furnace is used to heat your home and how much is wasted. For example if a furnace has an 80% AFUE rating then 80% of the heat generated is used and 20% is wasted. That 20% wasted amount can add up to a significant amount of money over time when translated on your utility bills.

What is a good AFUE rating?  Efficiency ratings have improved a great deal in recent years. Natural gas and propane furnaces are typically the most efficient and cost effective type of forced-air furnace on the market today. A furnace must have a minimum 90% AFUE to be considered a high efficient furnace.

Today there are several rebates offered for upgrading your old furnace to a new high efficient one. If your furnace is 10 or more years old, it is likely not running very efficiently. It may be time to evaluate your options and look at replacing (or converting) your old system for a new high efficient one and start saving money on your utility bills!

 

Single-Stage Versus Two-Stage furnace? 

The main difference between a Single-stage and a Two-stage furnace is the heating output. A Single-stage furnace has one level of heating output-full capacity. When the furnace kicks on, it runs until it reaches the temperature on the thermostat and then turns off. With a Two-stage furnace there are two levels of heating output-low for milder days and high for colder days.

Benefits of a Two-stage furnace: benefits apply when the furnace is running at the lower setting.

  • More even heat distribution as the unit runs for longer periods of time.
  • Quieter operation as there is no sudden blast of hot air.
  • Improved air filtration
  • Burns less fuel as it is running at a lower capacity

Which stage of furnace is right for you? There are many factors to consider when deciding between a single or two stage furnace. Consider price, temperature where you live, rebates available to you and personal preference. Have questions?

AC Talk! Energy Efficiency ratings for your AC and what they mean:

EER (Energy Efficiency Ratio)- measures the cooling capacity ( BTU’s per hour) to the power input (watts). The higher the EER rating is the more efficient the air conditioner will be.

SEER (Seasonal Energy Efficiency Ratio)- measures the annual energy consumption and efficiency of the unit’s cooling ability in typical day-to-day use.  The higher the SEER rating, the less energy the unit will use.

TON- One ton of cooling is equal to 12,000 BTU’s per hour.
