Sedna Aire believes that we can do something to reduce the effects of Global Climate Change through ENERGY EFFICIENCY. Thus, we have committed ourselves to provide the most energy efficient air conditioning systems for our homes and businesses. Sedna Aire uses a solar collector which displaces the electricity used in the cooling process. This allows us to achieve *0% to *0% savings as compared to the conventional air conditioning units in the market today. Sedna Aire uses the R**7C refrigerant which is more "ozone friendly" than the widely used R*2 refrigerant. Sedna Aire is the coolest, greenest, most cost effective way to cool your homes or businesses. With the savings that you get, you can actually get back your investment in 2 years. Sedna Aire provides a warranty of 5 years on ALL PARTS because we care for the people who invest in our products.
