Make your home energy-efficient. Whether you live in a new home, and most certainly if you live in an older one. Your utility bills will decrease in cost, the more energy-efficient your home is. For instance, if your home is older, you should seriously consider adding insulation into the attic. Your heating and cooling equipment works hard enough on any regular day. Making your home energy-efficient would lengthen the life of your HVAC unit. No matter if it is the dead of winter, or summer break. Everyone always wonders the same question… What degree is the best temperature to set your thermostat at and keep it at? You will want to set your thermostat so that both comfort and savings are maximized. Some believe that you should set your thermostat to your target degree and then leave it there always. But what if you are gone all day? Do you still continue to heat or air condition an empty home? The reasoning, of course is that it takes the HVAC unit more energy to heat a cold house. The theory is the same when considering to air condition a hot house, as well. Then there is the other side of the thermostat argument. There are HVAC users that reduce the heat or air conditioning when the home is empty. But only if no one will be home for a long period of time. The reasoning behind this thinking, is the energy saved will offset the cost of the HVAC. The HVAC will have to work harder to cool a hot house or to heat a cold one.
