Central Heating Unit
Furnaces represent a conventional form of home heating systems that are common to most households. Using today’s technology, a furnace may often achieve high efficiency. Due to a secondary heat exchanger, much of the energy is converted directly to heat during combustion. At Green Air, we only install American Standard units that generate the highest efficiency, in the range of 93%-98% AFUE, depending on the nature of the installation.
The furnace industry characterizes heater efficiency with the AFUE, or annual fuel utilization efficiency, of the unit. The AFUE represents a numerical standard that measures the average efficiency for a thermal device for the duration of a typical season or year.
A heater’s output is measured in BTU/h (British Thermal Units per hour). The size of your home, the R-value of your insulation, and the design of your ductwork primarily influence the size of the furnace required to produce absolute comfort throughout your home.
If you are in need of service or repair for your central heating unit, or you are considering replacing your existing unit with one that is more efficient, please contact us today. You can get in touch with a Green Air representative by phone at 925-284-7336, or schedule an estimate request via the attached contact form.
PG&E currently offers rebates for installation of a high energy efficiency natural gas furnace. PG&E rebates start at $200 for a 92% AFUE furnace, up to $300 for a 94%+ AFUE furnace. They also offer a further $50 for variable speed or modulating units. We at Green Air take great pride in offering superior customer service, and we will assist our clients by offering the required forms and information to collect their rebate upon job completion.
Central Cooling Unit
Cooling in a home is accomplished using a heat exchange process, which may take the form of phase change or active heat transfer. The phase change process is used in conventional air conditioners, while active heat transfer is employed via heat pumps. Regardless of the cooling method, cooling efficiency is represented by SEER, or seasonal energy efficiency ratio. The higher value for SEER, the more efficient the unit manages electricity to deliver cooling to your home. Presently, all residential cooling units are required to achieve a minimum SEER value of 13, and become Energy Star qualified with a SEER value of 14 or greater.
A cooling unit’s output is measured in either BTU/h or tons. The required output is primarily influenced by the amount of area in need of cooling in your home. We at Green Air will help you determine the appropriate size for your cooling unit and the efficiency that maximizes performance for your investment.
Do you have a larger or multi-level home? You can save energy by installing a zoning system. This permits your cooling system to cool only the areas of the home you plan to occupy for the day, all at the touch of an easy-to-use, programmable thermostat.

Ducts are used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. These needed airflows include, for example, supply air, return air, and exhaust air. Ducts also deliver, most commonly as part of the supply air, ventilation air. As such, air ducts are one method of ensuring acceptable indoor air quality as well as thermal comfort.
Efficient Ductwork improves the air quality in your home and can save you on your utility bills. A home with properly designed and sealed duct work can make your home more energy efficient and comfortable.
What are the benefits of green safety ductwork?
- Eliminates hot and cold spots throughout your home
- Poisonous Gas-Free—proven to be free of carcinogen formaldehyde
- Reduces the potential for mold growth in your ductwork
- Can lower utility bills by as much as 30% Made with environmentally friendly materials
