FAQ Answer

Q.

Can I use my Unionaire ductless system in winter?


A.

Only electric heat units all others will need an accessory.  Unionaire ductless systems can only be used while outside temperatures are above 32° Fahrenheit.  Ductless systems utilize an outdoor unit and like central air conditioners will not work in very cold temperatures.  Operating Unionaire products outside of recommended temperature ranges voids the warranty and will most likely cause damage to the outside compressor.  An extreme low-ambient kit can be added to reduce the outside temperature range to -5° Fahrenheit for operating in cool mode.  To operate heat pump units in temperatures below 32° a contractor can install a crank case heater to warm the refrigerant in the condenser in cold temperature.  All units with electric heat can also be used in cold climates.  Heat pumps are not electric heat units.
