Gas Heating

Heating is the number one energy expense for most customers. In fact, heating can account for more than half of your total gas bill. Switching to a natural gas furnace or upgrading to a more energy-efficient model can help save you money.

Southern California Gas Company (SoCalGas®) provides weatherization and furnace repair/replacement to qualified limited-income customers.

  • Save up to 30 percent on heating costs by lowering your furnace thermostat by three to five degrees (health permitting).
  • Install a programmable thermostat to help automatically regulate your home's temperature for comfort control and energy savings.
  • Save up to 25 percent of your heating costs by installing or upgrading insulation in your attic and walls.
  • Keep your heating system tuned-up to operate at maximum efficiency.
  • Clean or replace your furnace filters according to manufacturer recommendations and save up to 2 percent on your heating costs.
  • For safety and efficiency, keep all heating vents and furnace registers free of dirt, lint and obstructions.
  • Have your air ducts tested for leaks. Ducts should be repaired with mastic-type sealant not duct tape. You could save up to 20 percent of your heating costs.

Programmable Thermostats

  • Programmable thermostats save on heating costs by automatically turning thermostats down or off when you want and back on again when you need heat.
  • Programmable thermostats are available in do-it-yourself or professional installation models (including units with several settings to turn heat down at night and during work or school hours when the house is empty) and units that handle both heating and air conditioning for year-round savings.
  • Before buying a thermostat, consider the following:
    • Is the thermostat compatible with the electrical wiring found in your current unit?
    • Are you able to install it yourself, or should you hire an electrician or a heating / air conditioning (HVAC) contractor?
    • Are the programming instructions easy to understand?

Appliance Selection Tips

  • SoCalGas provides weatherization and furnace repair/replacement for qualified residences of limited-income customers.
  • When buying a new gas furnace look for a unit with a higher Annual Fuel Utilization Efficiency (AFUE) or an ENERGY STAR® label.
  • Did you know that by replacing a central forced air-furnace that is 15 years old or older with a new energy-efficient model, you could save up to 20 percent on heating costs?
  • When choosing a furnace, be sure to take into consideration the size, location, construction and insulation of your home. A system that is too large wastes fuel and money because it keeps cycling on and off. Ask a qualified gas heating contractor to estimate the heat loss of your home and recommend an appropriate size for your new furnace.
  • Low-interest financing may be available for the installation of energy-efficient heating systems.
  • Energy Guide labels can help you choose a cost-cutting furnace.
  • Check for available rebates.
