The other day I was in a department store looking at their house improvement section. I was mainly looking at landscape ideas plus trying to find some landscaping supplies so I could beginning planting Springtime flowers plus getting rid of the dead plants that did not make it through winter. While I was in an aisle I heard someone talking about their Heating, Ventilation in addition to A/C system. That reminded me that I needed to set an appointment with my local Heating, Ventilation in addition to A/C provider to have him take a look at it plus I wanted to ask him a few questions about how energy-efficient my Heating, Ventilation in addition to A/C system absolutely is. If there was a way, I would like to substitute my system to a more energy efficient system. When he arrived a week later I asked him how could I find out how energy-efficient it was. He told me that I could look for the SEER number on my a/c. The Seer number measures the cooling efficiency from the a/c or the heat pump. The higher the Seer number means the more energy efficient it is. I could also look at the AFUE (Annual Fuel Utilization Efficiency) percentage for gas plus oil heaters. This percentage tells you how much fuel is absolutely used to heat your house plus how much is wasted. There is also a HSPF (Heating Seasonal Performance Factor) rate that measures the efficiency level of the heating mode in heat pumps. I never knew of these types of ratings before plus I was genuinely blissful to hear about them so I could spend money attention to it plus make an energy difference in my home.
