Q. What size heating and cooling system should I have?
A. The correct size of your system is based on running a computer generated load using measurements of your home’s interior space. If you put in an oversized furnace it will not run long enough to get to its steady sate efficiency. If you put in an oversized A/C unit it will not run long enough to remove humidity.
Carbon monoxide (CO) is a killer at certain concentrations. By interfering with your body's ability to carry oxygen, the colorless, odorless gas can lead to serious trouble, including brain damage and death. But it's also a natural by-product of all forms of combustion, including the combustion taking place in a gas furnace, which is why furnace maintenance and CO detectors are so important to your home health. And if your CO detector goes off, it could point to a serious issue with your HVAC system.
