An experienced heating, ventilation and air conditioning, or HVAC, professional should install any propane furnace. Finding a fully licensed and insured technician is vital, because an improperly installed propane system is a major fire hazard.
Once a professional has installed the unit, a propane furnace requires little maintenance from a homeowner. However, the furnace requires an inspection for leaks at least once per year by a qualified service technician to ensure that it keeps working safely and efficiently.
Although propane costs more than natural gas or heating oil, propane furnaces can last five to 10 years longer than electric furnaces.
