The AHAM Certification Program for Room Air Conditioners

The Public's Interest is Paramount
The consumer - through AHAM's Room Air Conditioner Certification Program - can be certain that the nameplate of a room air conditioner accurately states the unit's cooling and heating capacity rating and amperes, as well as EER (if listed). The AHAM Certification Seal on the unit and listing in the AHAM Certification Directory verify this.

Scope of the Program
The program is open to all manufacturers, both members and non-members of AHAM, and to firms that market private brand models. Participation is voluntary. All models manufactured or marketed in the United States by a participant must be certified for cooling and heating capacity, EER and amperes. Certification covers both residential and built-in models.

Certification Seal
The AHAM Room Air Conditioner Certification Seal is
the mark issued by AHAM to all manufacturers and
private brand resellers of room air conditioners who are licensees in the program. The seal assures that the cooling capacity, heating capacity; EER and ampere ratings of all room air conditioners bearing this mark are determined and accurately stated in accordance with American National Standard ANSI/AHAM RAC-1 (latest

The AHAM air conditioner certification seal - illustrated on the preceding page - was especially designed for this program and is attached to each unit of a model certified under the program. A dark green seal approximately 1 1/4 inches square with the words "capacity, EER and amperes" is affixed to air conditioners with cooling capability as well as on models with both cooling and heating capabilities.

The BTU/hr cooling and heating capacity and electrical input during cooling in amperes are included on the nameplate of the unit; EER may also be included on the nameplate. Because testing of cooling-heating models is based on simulated use conditions, rather than maximum
operating conditions, certified ampere data for heating may be less than the nameplate value. When considering electrical installation requirements, the nameplate should be checked for maximum amperes in order to assure sufficient electrical circuit amperage.

Application of the Seal to Units
Participants are required to affix, or have affixed, the certification seal or an acceptable facsimile to all their certified Room Air Conditioners only at the time and place of manufacture of the room air conditioner.

Test Procedures Verify Accuracy of the Ratings
As sponsor and the verifying authority of the program, AHAM retains a testing laboratory (Intertek Testing Service/ETL SEMKO of Cortland, New York) to administer the testing of models and verification of data. Sample units are tested for compliance with the American National Standard ANSI/AHAM RAC-1 (latest edition) and the Procedural Guide for the Room Air Conditioner
Certification Program.

The standard covers definitions, ratings, testing
conditions and a sample cooling load estimate form for room air conditioners. The complete standard is available from AHAM.

The following subjects covered in AHAM standards are particularly pertinent to the definition and measurement of certified data:
   Cooling Capacity
   Heating Capacity
   Nameplate Data - The nameplate of each room air conditioner includes the following information:

   • Data in accordance with Underwriters Laboratories Inc. Standard 484 for Room Air Conditioners.
   • Electrical cooling power input in amperes at AHAM rating conditions. Electrical heating power in amperes at AHAM rating conditions may be used if properly identified.
   • Total cooling capacity and heating capacity if applicable, expressed in BTU/hr according to ANSI/AHAM RAC-1 (latest edition).

Cooling Capacity Rating Test - The cooling capacity rating of room air conditioners is derived from data obtained at the standard test conditions specified in ANSI/AHAM RAC-1 (latest edition) when tested according to ANSI/ASHRAE 16.

Heating Capacity Rating Test - The heating capacity rating of room air conditioners is obtained from data at the standard test conditions specified in ANSI/AHAM RAC-1 (latest edition) when tested according to ANSI/ASHRAE 58.

Energy Efficiency Ratio (EER) - EER is the value
determined in accordance with ANSI/AHAM RAC-1
(latest edition) and DOE Test Procedures. It is reported to the U.S. Federal Trade Commission for labeling purposes as required by regulations enacted under the Energy Policy and Conservation Act, Public Law No. 94-163 (1975). EER may be included in the nameplate data.

Electrical Rating Test - Electrical data are determined by tests conducted in accordance with ANSI/AHAM RAC-1 (latest edition).

Selection of Models to Test
The certification program requires that 50% of each licensee's new basic models and at least 10% of each licensee's carryover basic models be tested to average a 25% basic model testing program. At least one additional unit is tested of any model whose production during a program year exceeds 20,000 units. The laboratory retained by AHAM determines which models to test. The manufacturer does not know which models are to be tested, nor when any test will be conducted.
Rerating Models
If testing by the laboratory shows that a participant has incorrectly rated a model's cooling or heating capacity, EER or amperes, the model must be re-rated, and the manufacturer must inform the dealers in his brand (through his distribution outlets) of the new rating or ratings. He must also arrange to have labels displaying re-rated data available for models on display and those placed on display at a later date. The revised rating or ratings also are noted in the AHAM Certification Directory. Any participant who does not so comply can no longer take part in the certification program.

AHAM's Directory of Certified Room Air Conditioners is a listing of current program models of each participating licensee in AHAM's Room Air Conditioner Certification Program. Upon receipt of complete information for new or updated certified models from the AHAM certification program participants, the data contained in this on-line Directory is normally updated within 7 business days.

Directory Listings
All models are for operation on 60-cycle electrical

• Cooling capacity and electrical input ratings of all models are measured at standard test conditions specified in ANSI/AHAM RAC-1 (latest edition). The electrical input ratings (i.e. amperage) listed in this directory should never be used for electrical line sizing or fusing. Such information should be obtained from manufacturer's literature and/or the nameplate of the room air conditioner.

• The EER ratings of all models are determined in accordance with ANSI/AHAM RAC-1 (latest edition) and DOE Test Procedures.

• Where dual ratings are shown for a single model, they pertain to dual line voltages.

• Built-in units are for use in through-the-wall
installations. The thickness of the wall or any other limitations for such use will be indicated in the manufacturer's instructions for installation provided with the unit.

• The actual model number appearing on the nameplate of a room air conditioner may vary slightly from the model number shown in this directory because of production identification codes. These codes are usually comprised of the last letter or digit, or group of same, in the model number. Some manufacturers use these codes as an internal control technique to designate such things as the type of mounting kit packages with the unit, decorative changes, etc. The code appears on the unit nameplate and often is used in sales literature. However, since it is used to indicate differences between units of the same model and since these differences do not affect certified values, only the basic model number is listed in this directory.

• All models with heating capacity are also listed in Section 1 or 2. Certified heating data for these models is listed immediately below the certified cooling data. This data is determined according to AHAM procedures because heating capability is not covered by the Department of Energy Test Procedure. The heating capacity and electrical input ratings are measured at standard test conditions, which are: room air temperature, 70..F dry bulb; outside air temperature, 47..F dry bulb, 43..F wet bulb.

BTU - British thermal unit - the quantity of heat required to raise the temperature of one pound of water 1 degree Fahrenheit.

Cooling Capacity, BTU/hr - The quantity of heat in BTU's a room air conditioner is capable of removing from a room in one hour's time.

Heating Capacity, BTU/hr - The quantity of heat in BTU's a room air conditioner is capable of adding to a room in one hour's time.

EER - The energy efficiency ratio (EER), expressed in BTU's per watt-hour, is the quotient of the cooling capacity of the unit in BTU's per hour divided by its electrical input power in watts.

Ampere - A unit of electrical current. The quantity of current flowing into the air conditioner from the line.

Volt - A unit of electrical pressure. The pressure that exists in the power line and that moves the electric current through the air conditioner.

Listing by Type and BTU/hr Order

Models are presented in the following categories:

Window Models
- Cool Only
- Heat Pump
- Electric Heat

Special Application Models (cooling units)
- Casement Only
- Slider/Casement

Through-the-Wall Models
- Cool Only
- Heat Pump
- Electric Heat

Each of these categories is further divided by cooling capacity (BTU/hr) and voltage. Models within each of the capacity groups are listed from the lowest to the highest capacity.
Through-the-wall models may list two sets of EER’s to indicate the unit's operating efficiency when installed in different, model compatible sleeves. For each model you will find the following information:

• Brand Name
• Model Number
• Volts
• BTU/hr
• Amps
• DOE Energy Efficiency Ratio

A unit's Energy Efficiency Ratio (EER) is determined by Department of Energy (DOE) test procedures. The EER listed for each model in this guide is the same as the big number on the yellow EnergyGuide label attached to the unit. You'll notice that many models show two EER’s to indicate their relative operating efficiency with two different voltages.
