Green is the new buzz word, but what does it really mean to go green in the heating and cooling industry?

“Air conditioning accounts for nearly 50% of the energy use in the United States during peak summer months, and air conditioning is responsible for nearly 100 million tons of carbon dioxide emissions every year.” - Rocky Mountain Institute

There are many ways to achieve a green home. Our approach to designing a cooling system for a green home focuses on energy efficiency and increased occupant health. Ultimately, our goal is to help you reduce your carbon footprint.

One of the biggest ways to make a difference in reducing your energy consumption is through your cooling equipment. According to the Department of Energy, 56% of your household energy use is from your heating and cooling system. Installing a high efficiency cooling system can reduce the total annual energy consumption in your home by as much as 30%.

One of the primary areas that greatly impacts energy efficiency is the ductwork in your home. According to the Department of Energy, the average air leakage for a home’s duct system is 20%. We have been testing many duct systems and we have been seeing leakage averaging 40-50%. The average leakage for a duct system that we install in a Green Home is less than 3%. All of our ductwork systems for new construction Green Homes are certified by a third party energy rating company.

With the world crazy to "go green" we are seeing a new system being implemented in the way we use air conditioning.  The existing system which many people refer to as Freon is actually what is termed R-22. The R-22 refrigerant is being replaced by the R410a refrigerant which is a much more environment friendly and energy conserving system.  This overhaul is slated for 2010 and will replace the R-22 with the R410a completely because they work on two opposite pressure systems.

 The copper lines that the R-22 use will need to be changed out because it uses mineral oils that break down into damaging carbons that are speculated to be causing the global warming crisis the governments of the world seem to be so worried about. R-410a will use synthetic oil that will be able to sustain at much higher temperatures than that of the old. So if you have an older system which uses R-22 coolant, now is the time to upgrade.

There's even more incentive to green now due to the tax credits. Look for rebates for your state on the Dept. of Energy web site Hawaii on the Hawaii Energy website at Some restrictions apply.

Your tax advisor can help you determine how these credits may help you.

 It’s the perfect opportunity to upgrade your home with an energy-efficient heating and cooling system to get a major tax break!

Something to think about…

According to the Department of Energy, if just one household in ten bought ENERGY STAR heating and cooling equipment, over 17 billion pounds of pollution would be prevented.

Don't forget other ways to save the environment:
  • Energy Star Heating and Air Conditioning systems
  • Programmable Thermostat- temperature settings can be programmed based of your schedule    saving energy while you are away or asleep
  • Yearly Preventive Maintenance to ensure efficient operation and optimum savings
  • Change filters often. A dirty filter will cause your system to run harder, using more energy
  • House fans keep your air moving, saving air conditioning energy when temperatures aren't too high. A "whole house" attic fan is a major plus!
