The home is an older home that I am going to use as a rental. I know nothing about forced air or whether there is duct work. Should I assume there is and in that case only need a unit? Thanks!
G--o--o--l-l-lly!! Are you asking for an out-and-out quote in final cost $s? There are ALL KINDS of specific information that anyone would have to know before giving you even the WILDEST estimate of cost, e.g.: 1. Is it a true forced-air heating system with a fixed furnace and ducting to the various rooms? Does the blower have enough capacity to overcome the extra resistance of forcing the air past the new cooling coil for central heating cooling? 2. Is the furnace in a basement or on the floor level of the house and is it in good operating condition with no problems in proper air circulation to all outlets and insulation on the outside of all ducts in good, SEALED condition? 3. Is the fuurnace of the type that is designed to accept a new add-on cooling coil for air conditioning and have enough clearance between it and a ceiling or floor above before the connection to the existing plenum chamber? 4. How many BTU/hr. heat removal that will be required to do the job will determine the cost of the new refrigeration compressor/heat exchanger unit, complete with 220+V electrical hook-up and connecting cooling gas piping to and from the cooling coil necessary to provide the needed heat removal (usually with a little extra capacity)? 5. How many manhours of expensive electricians, plumbers, carpenters, and very probably insulators, etc. will be required to finish the job? I don't know, but as you can see, it will be a fairly complex project and I believe you would be well-advised to seek a good reputable and reasonable general contractor to do the job. For it to be done RIGHT it ain't gunna be cheap!
