    Compressor

    I have a 3 bedroom condo and I need a new compressor for my A/C. Is a 3HP compressor too big?

    3 HP as in horsepower? Air compressors are measured in HP. Air conditioner compressors are measured in tons or Btu

    Refrigerant compressors are measured in horsepower or kilowatts in other countries.

    For A/C 1 HP~= 1 ton.

    For larger temp differences BTUs per HP goes down so a 1HP compressor from a window shaker moves more BTUs than a 1 HP on a sub zero freezer.

    Nobody can answer this question without doing a load calculation.

    Sounds like someone has a 3HP compressor laying around.
