Looking for rough ballpark estimate for total cost of putting in air conditioning in apartment units. We actually have two apartments on 2nd floor in same building, one is 1BR about 600 sq. ft, across the hall is larger 2 BR maybe 1000 sq. ft. Was wondering about Mitsubishi wall units and putting one in each apartment even though larger one maybe could use more. So, two units plus one compressor plus installation? Tenants pay their own electric.
