Commercial air conditioning systems and heaters are, of course, much larger than conventional residential AC units. Otherwise, there are not many differences between commercial systems and residential systems; they all run on refrigerant and use coils and blower fans to remove heat and cool a space.
However, there is typically a difference in the way air conditioners are installed on commercial buildings and the way they are installed in homes. A rooftop packaged HVAC unit is the best choice for many commercial properties (though not all). This type of AC and heating system sits on the rooftop of the building, and it tends to be the best choice for many of the commercial air conditioners and heaters in our area.
At first thought, a freezing air conditioner may not sound like that big of a problem. After all, you want your AC to be cooling your home, right? Of course you do–but remember that there is a huge difference between an air conditioner and a freezer. Your air conditioner should be removing heat from the air in your home and recirculating that air back into the living space at a lower temperature. At no point should it be freezing up, though.
Usually when we talk about leaks in air conditioning systems, we may be talking about oil or, unfortunately for some, refrigerant. However, every now and then we get a call from a homeowner concerned that their air conditioner is actually leaking water. This is not only alar ng, but also perplexing. After all, it is not as though an air conditioner actually uses water in its operation, right?
