The SoCalGas Home Upgrade Program is looking for projects that upgrade wall or floor furnaces to a central system.
Homeowners in pre-1978 housing stock with a floor or wall furnace can realize significant energy savings by installing a central HVAC system. Installing new central heating with tight, well-insulated ducts alone can provide up to 12% savings in some homes. Install additional measures and the savings go up.
(Please note that the savings illustrated below are from a sample home modeled in Snugg Pro. Actual savings will vary depending on the location, configuration and energy features of your customer’s home.)
Example 1: Your customer lives in a 1,500 sq.ft. single-story 1960’s home in climate zone 9 with a wall or floor furnace and no cooling.
Install a central heating system that includes a new 95 AFUE central furnace with new R-8 ducts sealed to 5%, and your customer could see 12% annual energy savings. Add R-38 attic insulation to the improvements and total energy savings could increase to 19%.
Example 2: This customer lives in a 1,500 sq.ft. single-story 1960’s home in climate zone 9, with a wall or floor furnace and a window/wall air conditioner to cool a portion of the home.
Install a central HVAC system that includes a new 95 AFUE central furnace, new 16 SEER split AC, new R-8 ducts sealed to 5% and R-38 attic insulation. The customer could see 15% annual energy savings. If the homeowner uses multiple window or wall AC units, the savings will be even greater.
Other potential upgrade measures could be combined to increase savings:
- Crawlspace insulation could add 9% savings.
- New windows could add 3% savings.
- A new tankless water heater could add another 10% savings.
The examples above show the potential benefit from replacing non-central HVAC systems in the SoCalGas Advanced Home Upgrade program. This type of HVAC upgrade requires energy modeling with Snugg Pro or Optimizer.
Please note that images of existing installed window and wall AC units and their data plates are required.
Please refer to modeling handbooks for more information on how to properly model a project or contact your ICF Account Manager.
Thank you for your continued support of the SoCalGas Home Upgrade program.
