Meeting Government Efficiency Standards

Meeting Government Efficiency StandardsAs government standards and requirements evolve to require heating and cooling manufacturers to improve product efficiency and use environmentally responsible materials, Bryant continues to lead the way. From developing high efficiency heat pumps and air conditioners to introducing Puron® Refrigerant, Bryant puts experience to work to create the rock-solid heating and cooling products of tomorrow.

High SEER Requirements for 2006

Like many consumer products that use energy, air conditioners and heat pumps are manufactured to meet or exceed minimum efficiency standards set by the U.S. Department of Energy. After nearly a decade with 10 SEER (Seasonal Energy Efficiency Ratio) as the minimum efficiency, January 23, 2006 marks the mandated increase to 13 SEER.

Who will this affect?

The 13 SEER minimum applies to all new equipment manufactured on or after January 23, 2006. You may continue to use your current system indefinitely, even if it operates below 13 SEER, but when it's time to replace your system, only 13 SEER or higher models will be available.

Higher SEER means cost-saving energy efficiency

For many homeowners, a 13 SEER air conditioner or heat pump will save money on each month's electric bill. Exactly how much you can save will depend on the efficiency of your current system. For example, a 13 SEER product:

  • Delivers about 23% energy savings compared to 10 SEER models
  • Delivers about 8% energy savings compared to 12 SEER models

Actual savings will depend on the age, efficiency and condition of the unit being replaced, but if you are currently considering a new air conditioner or heat pump, it makes a lot of sense to start saving now with a 13 SEER product. Bryant offers several heat pumps and air conditioners that meet and exceed the 13 SEER requirement–even up to 18 SEER.

To learn more about the 2006 13 SEER efficiency mandate, visit www.energy.gov.

Refrigerant Upgrades

Puron RefrigerantAnother change you need to be aware of is the phase out of R-22, the refrigerant most commonly used in today's air conditioners and heat pumps. By 2010, all new air conditioners and heat pumps will be required to use a non-ozone-depleting refrigerant, such as Bryant's environmentally sound Puron Refrigerant. This phase out has been mandated in an effort to help protect the Earth's ozone layer. By making the change to Puron Refrigerant now, you can protect yourself from the potentially higher future costs of servicing an air conditioner or heat pump that uses R-22.

Bryant Leads the Way

Whether it's developing tomorrow's efficient and cost-saving 13 SEER and higher air conditioners and heat pumps, or offering a wide range of products with environmentally sound Puron Refrigerant, Bryant is putting experience to work to develop the heating and cooling products that will keep your family comfortable tomorrow.

Efficiency Ratings Explained

How ratings affect cost savings

In your mission to find the perfect Bryant comfort system for your family, you will come across several important industry-standard efficiency ratings. The higher efficiency your product, the lower your long-term energy costs will be. And as always, your experienced neighborhood Bryant dealer is just a call away to help you choose the heating and cooling products that are right for you.

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. Bryant offers a full line of furnaces with AFUE ratings ranging from the minimum industry requirement of 78% 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. Bryant'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. Bryant 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 your experienced Bryant dealer 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.

Heating & Cooling with Hybrid Heat Systems

Bryant Hybrid Heat™ Systems combine the strengths of two heating sources to deliver the warmth and efficiency you deserve this heating season. Yet it also cools your home in the summer and there's money savings potential there as well. The Hybrid Heat system is so efficient, the cost to heat with it is less than with any gas furnace alone — even a 100% AFUE furnace!

Hybrid HeatA Hybrid Heat System provides more control over your monthly energy bills by allowing you to choose the most economical method of heating. As conditions change, the system automatically switches between the two sources to maintain greater efficiency than with a single-source heating system.

Because Hybrid Heat provides the flexibility to react to changing energy costs, it's an excellent investment for long term peace of mind, comfort, and protection against unpredictable fuel cost increases. Hybrid Heat Systems deliver exceptional performance using a heating source that provides its most energy-efficient comfort during moderate heating conditions. As the temperature drops outside, the system automatically switches to your second heating source when that becomes the most economical way to keep your family comfortable during more extreme outdoor conditions. Just as you would with any typical heating system, simply set your desired comfort level, and let Bryant's Hybrid Heat do the rest.

HeatingComfort All year Long — Heating

Bryant's ultimate Hybrid Heat System combines the Plus 90i gas furnace with one of our Evolution series heat pumps to provide soothing, superior comfort during both heat pump and furnace operation. This powerful combination can deliver heated air temperatures that are warmer than most traditional heat pumps so air from your vents feels warmer to the touch.

The Hybrid Heat Cooling Story

CoolingBecause a heat pump also provides cool, indoor comfort when it's hot outside, a Bryant Hybrid Heat system becomes your total, year-round indoor comfort solution. And with the recent increase in efficiency of air conditioners and heat pumps from 10 to 13 SEER (Seasonal Energy Efficiency Ratio), a Hybrid Heat system could save you money during the cooling season.
