Why Many Homeowners Choose a Heat Pump Instead
A heat pump costs about the same to install as central AC in many homes, and it also heats. For houses that only need cooling a few weeks a year, getting heating out of the same equipment is often the better value.

Air Conditioning Installation Questions
Do I need a permit to add AC?
In unincorporated King County, installing, replacing or relocating a furnace or air conditioner needs a residential mechanical permit, applied for through MyBuildingPermit.com. Homes inside Woodinville, Redmond or Bothell city limits go through that city instead.
Can AC be added to my existing furnace?
Usually, if the furnace and ducts are in good shape. The coil sits on top of the furnace and the outdoor unit connects to it.
How long does installation take?
Most installs take one to two days.
When should I schedule?
Fall and early spring usually have the shortest wait, well before the first heat wave.
