Efficiency Ratings Explained

Efficiency ratings play a huge role in the size of your monthly utility bills. However things like seasonal maintenance and a proper HVAC installation also affect what heating and air conditioning costs you each month. Zack Hammonds A/C Heating Refrigeration Inc is a leading Atlanta air conditioning and heating contractor. We specialize in efficient, reliable HVAC solutions for our customers. Read below to learn more about efficiency ratings, or call us today at (770) 691-3162.

AFUE (Annual Fuel Utilization Efficiency)

AFUE is the standard measurement of efficiency for gas and oil-fired furnaces. Given in percentages, this number tells you how much of your fuel is used to heat your home and how much fuel is wasted. The higher the AFUE rating, the greater the efficiency. Zack Hammonds offers a full line of furnaces with AFUE ratings ranging from the minimum industry requirement of 80% to more than 96%.

Cost Savings: If you have an older furnace (with an AFUE of approximately 60%), you could save up to 40% on your heating bills by replacing it with a new high efficiency furnace! The cost to replace your old, inefficient furnace is paid back through lower utility bills.

SEER (Seasonal Energy Efficiency Ratio)

SEER is the measure of efficiency by which the cooling process of air conditioners and heat pumps is rated. The higher the SEER number, the greater the efficiency – and therefore greater energy savings. Today, U.S. regulatory agencies require all new products to have a 13.0 SEER rating or better. Trane’s full line of air conditioners offers SEER ratings of up to 20.

HSPF (Heating Seasonal Performance Factor)

HSPF is the efficiency measurement used to gauge the efficiency of the heating mode of heat pumps. The higher the number, the greater the efficiency and cost-savings. Today’s models are required to have a 6.8 HSPF. Trane offers heat pumps with HSPF ratings ranging from 6.8 to 9.5.

Cost Savings: Higher efficiency in heat pumps and air conditioners usually means higher equipment cost but lower utility bills. If you live in a warm and/or humid climate, you will probably see the higher cost of a high efficiency air conditioner or heat pump paid back (through lower utility bills) in a few short years. Ask Zack Hammonds A/C Heating Refrigeration Inc to help you determine about how long it would take you to recover the additional cost in energy savings. Of course, long after the payback, you continue to save on your energy bills.

Matching Your System for Optimum Efficiency

One additional factor that affects the efficiency of your air conditioning or heat pump system is your indoor coil (also called an evaporator coil). If your condensing unit is not matched with the proper indoor coil, it may not give you the stated SEER and/or HSPF ratings and could even develop performance problems. When you replace an existing system, make sure you replace both units so your new condensing unit will give you optimal performance, efficiency and comfort.
