ENERGY STAR® - Heating, Cooling and Ventilation
Room Air Conditioners
List of models: Room Air Conditioners
2007 EnerGuide Room Air Conditioner Directory
ENERGY STAR qualified room air conditioners use at least 10% less energy than conventional models. The following table shows the energy efficiency ratio (EER) requirements for the various styles and cooling capacities. The ENERGY STAR symbol may also appear on the EnerGuide label to show that the unit is ENERGY STAR qualified.

Standard style models are designed to fit into a slider or hung type window while through-the-wall models are for installation in a wall opening. Casement-only and casement-slider styles are designed so that they can fit into a casement type window. Note that a special electric plug is required for 240 volt models.
Central Air Conditioners
ENERGY STAR qualified central air conditioning systems are about 8% more efficient than standard models. The energy efficiency of this product is measured by Seasonal Energy Efficiency Ratio (SEER) and Energy Efficiency Ratio (EER). Typical residential systems are "split" with a separate indoor evaporator unit in the furnace ducting and an outdoor condenser unit. There are also "single package" systems that have the evaporator and condenser in one unit. The following levels must be met or exceeded to qualify for ENERGY STAR:
| Type |

Technical Specifications For Manufacturers
Buyer's Guide to Home Air Filters [This link opens a new window] provides consumers with balanced guidance in purchasing residential air filters. While the guide represents their assessment of the current state of knowledge on residential air filters, it does not necessarily reflect the view of any particular participating organization.
Residential Furnaces (forced-air)
Gas or Propane Fired Furnaces
A gas or propane fired furnace's energy efficiency performance over a heating season is called the Annual Fuel Utilization Efficiency (AFUE). This AFUE is expressed as a percentage. The higher the percentage, the more efficient the furnace.
Some high-efficiency furnaces using a variable-speed direct current (DC) motor to run the air circulation fan, can significantly reduce electricity consumption while providing better heat distribution.
Residential gas furnaces must have an annual fuel utilization efficiency (AFUE) rating of 90 or higher to qualify for the ENERGY STAR mark. Some high-efficiency furnaces using a variable-speed direct current (DC) motor to run the air circulation fan, can significantly reduce electricity consumption while providing better heat distribution. ENERGY STAR designated heating and cooling equipment, when properly designed and installed, can save consumers from 15 percent or more on heating and cooling bills each year, depending on where you live, and how much you pay for your energy source. Either way, energy savings, will often pay for themselves over the life of the equipment.

Oil Fired Furnaces
An oil fired furnace's energy efficiency performance over a heating season is called the Seasonal Energy Utilization Efficiency (SEUE). This SEUE is expressed as a percentage. The higher the percentage, the more efficient the furnace. For furnaces with no standing pilot light, the SEUE is equivalent to the Annual Fuel Utilization Efficiency (AFUE).
Residential oil furnaces must have an annual fuel utilization efficiency (AFUE/SEUE) rating of 83% or more to qualify for the ENERGY STAR symbol.
Note: On October 1, 2008, the ENERGY STAR level for oil furnaces will increase to 85%.

List of models: Oil-fired boilers
Technical Specifications For Manufacturers
Boilers designed for space heating can also provide domestic hot water for residential applications. There are two basic methods used:
1. Indirect storage. These well-insulated tanks operate as a separate heating zone with substantially reduced heat losses and higher efficiencies as compared to tankless coils.
2. Tankless coil. Operating a boiler with a tankless coil will reduce the overall energy efficiency of the boiler.
Air Source Heat Pumps
ENERGY STAR qualified air–source heat pumps are about 6% more efficient for heating and about 8% more efficient for cooling than standard models. The energy efficiency of this product is measured by Seasonal Energy Efficiency Ratio (SEER) and Energy Efficiency Ratio (EER). Typical residential systems are “split” with a separate indoor evaporator unit in the furnace ducting and an outdoor condenser unit. There are also “single package” systems that have the evaporator and condenser in one unit. The following levels must be met or exceeded to qualify for ENERGY STAR:

Ground-Source Heat Pumps
List of models: Ground source heat pumps
Ground-source heat pumps use the thermal energy of the ground or groundwater to provide a source of heating and/or cooling for a home. There are three basic types: 1) closed loop; 2) open loop; and 3) direct expansion. The cooling function is measured by an Energy Efficiency Ratio (EER), and the heating function is measured by a Coefficient of Performance (COP). The higher the EER or COP number, the more efficient the heat pump is. ENERGY STAR qualified ground-source heat pumps must meet or exceed the following EER and COP levels:
| Product Type |
EER |

| Closed Loop |
14.1 |

| High |

2.1 m3/min. (75 cfm) per watt |
If your ENERGY STAR qualified ceiling fan doesn't include lighting and you wish to add it, be sure to purchase an ENERGY STAR qualified light kit. These kits come with either pin-based compact flourescent lamps (CFLs) or screw-based CFLs. This lighting is more efficient than standard incandescent lighting and long lasting, so you won't have to make frequent bulb changes.
Ceiling Fan Tips:
- Fans should be installed with the blades at least 30 cms below the ceiling, 200 cms from the floor and 60 cms from the nearest wall.
- Air should be moved downwards from the ceiling in the summer to provide a cooling breeze on the room occupants.
- If the fan is used in the winter, air should be moved upwards towards the ceiling to disperse the warm air that tends to accumulate there and distribute it more evenly in the room.
- During the summer, switch the fan and light off when you leave the room. Fans don't actually cool a room, they just cool you by circulating air.

Ventilating Fans
ENERGY STAR qualified ventilating fans use, on average, 65 % less energy than standard models. Because of better blade design, they move more air with less noise and their high performance motors last longer.
| Ventilating fans include: |
- range hoods
- bathroom fans
- utility fans
- in-line fans
If the fan contains a light fixture, the total lamp wattage must not exceed 50 Watts. The use of compact fluorescent lights (CFLs) is recommended. Fans with a "nightlight" must have a light bulb that consumes 4 watts or less. A minimum of a one year warranty is required. Qualifying ventilating fans may also have sensors, heaters, and timers.

Programmable Thermostats
Programmable thermostats must have at least two different programming periods (for weekday and weekend programming) and at least four possible temperature settings (i.e., wake, day, evening, sleep) to qualify for the ENERGY STAR mark. The thermostat should also be shipped from the factory with pre-programmed settings.
We are currently sharing lists of ENERGY STAR qualified programmable thermostats with ENERGY STAR in the United States. When you click on this link, you will be taken to a product list on the U.S. ENERGY STAR web site. Many of the products listed are available in Canada.

Technical Specifications For Manufacturers
The ENERGY STAR certification for programmable thermostats will cease as of May 1, 2008.
The ENERGY STAR initiative is suspending the certification specification for programmable thermostats as of May 1, 2008. To save energy and money, homeowners should set back their thermostats, manually or by using a programmable thermostat, at night and during the day when no one is at home.
