Manufactured Home CoolingEquipment Sizing GuidlinesFor ENERGY STAR® qualified manufacturedhomes and homes built to the HUD standards1

Oversizing cooling equipment: a costly mistakeThe guidelines offer a simple look-up procedure to assistequipment specifiers, HVAC contractors, home installers,retailers, manufacturers, and electric utility staff select heatpump and air conditioner capacity for new manufacturedhomes. The guidelines were developed to help eliminate theall-too-common problem of choosing equipment with far morecooling capacity than the home needs.

Oversized HVAC equipment is recognized as a common industryproblem that erodes energy efficiency and lowers customer satisfac-tion. Consumers overpay in two ways. First, they are buying equipment thathas more cooling capacity and is more expensive than they need. Second, onceinstalled, oversized equipment cycles on and off frequently, shortening equipmentlife, lowering efficiency, and increasing power bills. Oversized equipment also can lead to moisture problemswithin the home.

ENERGY STARENERGY STAR is a nationally recognized, voluntary labeling program designed toidentify and promote energy-efficient homes, buildings, and products to consumersand business owners across the United States. The U.S. Environmental ProtectionAgency is responsible for administering the ENERGY STAR for Homes program. AnENERGY STAR qualified home is at least 30% more energy efficient in its heating,cooling and water heating than a comparable home built to the 1993 Model EnergyCode. This increased level of energy efficiency is met by successfully integrating anenergy efficient building envelope (effective insulation, tight construction, advancedwindows), energy efficient air distribution (air-tight, well-insulated ducts), and energyefficient equipment (space heating and cooling and hot water heating).

ENERGY STAR qualified homes typically require less cooling capacity because their high insulation levels andtight construction slow the transfer of heat from outside into the home, and their tight air distribution systemsminimize the loss of conditioned air from the ducts.

Page 2: Manufactured Home Cooling Equipment Sizing Guidelines

How to use the sizing guidelines The sizing guidelines consist of a set of nine maps covering the continental U.S. and the Sizing Table contain-ing recommended cooling equipment sizes in tons. The maps are divided into counties. Contiguous counties that have the same sizing recommendations are combined into Sizing Groups.1 The maps and Sizing Table are available on the Web at http://www.mhrahome.org and http://www.energystar.gov.

Follow these steps to determine your recommended size:

1. Find the county where the home will be sited on the map and determine the corresponding Sizing Group number.

2. Find the row corresponding to the Sizing Group on the Sizing Table. The rows on the table are color-coded to match the colors on the map.

3. Determine the conditioned Floor Area of the home and read across the top row of the table locating the pair of columns containing that area.

4. To find the required cooling equipment capacity in tons for a heat pump or air conditioner, read down the column that corresponds to the Floor Area and across the row that corresponds to the Sizing Group.

5. The left-hand column in each pair represents the appropriate cooling equipment size for ENERGY STAR qualified homes. The right-hand column in each pair represents the size (in tons of cooling capacity) for homes built to the HUD-standards thermal requirements.

Example:

• An ENERGY STAR qualified home is to be installed in Richmond County near Ocala, Florida.

• The map indicates that Richmond County is in a Sizing Group 50.

• The home is a 28 ft. by 56 ft. multisection containing 1,568 square feet of conditioned living space (28 ft. x 56 ft.=1,568 sq. ft.).

• Referring to the Sizing Table, read across the row labeled Sizing Group 50 and down the column containing 1,568 square feet (1,441 to 1,680).

• Read down the left-hand (blue) column for an ENERGY STAR qualified home.

• This home requires a 3 Ton heat pump.

1Some counties are divided into more than one sizing group.

The values on the chart are intended as a guide for equipment selection. This information is not a substitute for proper evaluation and judg-ment by an equipment specifier. The cooling capacity estimates are based on typical home configurations and assumed design conditions. Actual sizing requirements may differ from the values on the chart. The Manufactured Housing Research Alliance and its members, the US Environmental Protection Agency, the Tennessee Valley Authority, the National Rural Electric Cooperative Association, sponsors of this work, assume no liability for errors in equipment sizing, selection, and installation.

Sizing charts are available for other regions of the U.S. For information on obtaining sizing guidance for other areas, please visit the Manufactured Housing Research Alliance web site at: http://www.mhrahome.org.

The Manufactured Housing Research Alliance developed the sizing charts. MHRA is a non-profit membership organization comprised of firms actively engaged in the manufactured housing business. Wrightsoft Corporation performed the engineering analysis.
