[Pros] Relatively inexpensive home heating system. Duct work can also be used for cooling during the warmer months. Easy to connect with a heat recovery ventilation (HRV) system. High efficiency air filtration can be added to these house heat systems to reduce symptoms for those suffering from allergies or asthma. [Cons] Can feel drafty. Without air filtration, a forced air furnace can make symptoms worse for those suffering from allergies or asthma. Lowers the humidity of the home so a humidifier may be required at some times during the year. [Heating System]
