CONS
Unfortunately, individually heating your rooms with a ductless heat pump has several drawbacks to consider.
· While safer and arguably less ugly than a window air conditioner, most mini-splits aren’t winning any home design awards. They stick out from the walls and are obtrusive, no matter how sleekly they’re made.
· If you want to change the temperature of your house, you need to change each thermostat individually.
· A professional, experienced installer is a must. Your installer should use a formula to determine the size of the unit you need. Correct sizing is essential for an efficient system.
· Installation can be expensive.
· They only heat or cool small spaces.
· They are high maintenance. Filters must be washed monthly, or you could end up needing an expensive professional cleaning.
Ducted Heat Pumps
Air-air heat pumps move heat from the outdoor air into your home (or vice versa). A ground source heat pump, or geothermal pump, uses the ground (or a body of water) as its heating source. After the heat is taken from its source, it is distributed throughout your home via a system of ducts.
PROS
Ducted heat pumps are what most people think of when (or if) they think about heat pumps. Having ductwork in your home can be convenient.
· They’re efficient and effective. An air-source heat pump can deliver up to three times more heat energy than the electrical energy it consumes. Ground source heat pumps are even more efficient.
· The duct system is convenient. A homeowner can extend the duct system throughout the home, so only one unit is needed to heat the entire building (depending on size).
