Heating and air conditioning is something we all take for granted. We probably don’t remember that each type of heating and air conditioning system comes with a “user beware” awareness. Why user beware? Well, the energy source, whether it be fuel oil, natural gas, propane gas, refrigerant, or ammonia that generates the heating or cooling, each requires precautions when used as part of an engineered system.
I thought I’d highlight how each of these systems can be hazardous but want to note that all these heating and cooling sources are safe to use when engineered, operated, and maintained correctly.
