When you talk about getting a new Heating and Air Conditioning method installed in a house, you’re talking about far more than a new gas furnace or air handler. This includes the air duct, the indoor air handler, the outdoor air compressor and condenser, the temperature control – everything that affects how warm or cool you are at condo is controlled by this system! That being said, if the gas furnace and cooling systems are the heart of the Heating and Air Conditioning system, the air duct is the circulatory system. So, it’s critical that you not only have the right sized gas furnace and air conditioning for your home, however also have the appropriately sized air duct! I made the mistake in the past of having small air duct laid out in the attic of our home. My thought process was that the air duct would be smaller, which would compress the cool air and make it come out of the vents faster. However, I hadn’t considered that the small size of the air duct would leave it susceptible to blockages far more often than conventional air duct! In more than two weeks, I had to have many odd appointments to have the air duct cleaned out. It was just our luck that Springtime had just begun, so the air filter for the a/c method was so loaded up with pollen that it started passing through into the air duct. It may be more expensive, however trust me – stick with the conventional air duct for your home’s Heating and Air Conditioning system!
