We strongly recommend that you upgrade to higher efficiency consumer products when the timing is right!
What do we mean by the aforementioned comment?
We mean use common a sense approach. Purchase high quality compact fluorescent light bulbs and replace your incandescent lights as they burn out. If you aren’t having repair issues with your current heating and air conditioning system or major appliance, don’t be in a hurry to rush out and purchase “high efficiency” systems. If you are having issues with your current system, and the system is over 10 years old, you may want to consider replacement to high efficiency equipment. In Indiana, Geothermal systems as well as air to air heat pumps with natural gas back up heating systems are good choices for comfort heating and cooling. Many of the manufacturers are offering two stage cooling units now as well with SEER ratings well into the high teens. Always do the math and consider product life cycle in your analysis and make sure your energy efficiency improvements are worth the additional money you will pay for higher efficiency equipment.
