Now that the cold weather is here and you are using your furnace, do you smell anything like rotten eggs, musty odors, chemical or odors, or a burning smell? If the answer is yes to any of those, then you do need to have the furnace checked out as soon as possible as it could be anything from bacteria in the air, to the furnace over heating, to a cracked heat exchanger which will allow Carbon Monxide to enter your home. Please give us a call and we will schedule our 80 point diagnostic evaluation of your furnace to confirm the source of the odor and advise you of your options for repair.
