Split Unit Air Conditioning

Less noisy than wall units, and more energy efficient than central units, split unit air conditioners are quickly gaining popularity all over the U.S. If you don’t have the ductwork in place or the need for a central unit, then split unit may be your best bet. Here is some more information.


The average cost of a standard split unit air conditioning system is $3,000 for the unit itself and up to $3,000 more for the installation.

  2. Make sure to cover the fan unit with a wash bag.
  3. Use a chemical cleaner to spray the coils and fan rotor. Leave for the amount of time recommended on the cleaner itself.
  4. Rinse the fan coil and rotor blade with water.
