Is it time for you to purchase a new furnace? Do you know where to start? When searching for a new furnace for this winter you have many choices to choose from. There are so many things to think about when you are going to purchase a new furnace. There are different brands, different efficiencies, different stages and more. Bartlett Heating and Air is a factory authorized Carrier and Lennox dealer. One of the choices you have to make is what percent furnace you want to purchase. Here is a brief explanation on what the percentage numbers mean. The 80% furnace is initially cheaper to purchase. The 80% means that 80% of the heat generated by the burnt fuel is used and the other 20% is wasted. It is not as efficient as the other models that have a higher number. The 90% furnace uses 90% of the heat generated and only 10% goes to waste. This is also called a condensing furnace because the gas is passed through a heat exchanger and then forced past radiator/coils and the remaining moisture is cooled, condensed, and released. The 90% is best for the comfort for your home. Both of these furnaces come in single and two stage models. The singles stage burns at 1 fixed rate when the thermostat tells its to turn on and turns off when the thermostat reaches the correct temperature. The two stage burns on heat demand at high or low power depending on the temperature outside. Bartlett Heating and Air has both 80 and 90% single and two stage furnaces to meet your needs.
