A/C size for 56x24 1986 home
Re: A/C size for 56x24 1986 home
You have a quality home...Any quality HVAC installer should be able to calculate the correct size...Do NOT oversize it will only cost much more to run and not do as good a job..Have you AC installer do a site visit to calculate your glass area and get an idea of the insulation in your home..
Good Luck with your project

i think as a guideline for every ton it should handle 500-700 sq ft but as rmurray stated windows, insulation etc....plays a factor as well.

Go to the Energy Star Central Air Conditioner Sizing Tutorial
This tutorial will ask you questions about your home’s location, windows, ducts, and insulation. Based on your answers, it will generate an air conditioner sizing recommendation (smaller than, larger than, etc.) and a list of your answers that you can use to work with your contractor.
Some contractors will use rules of thumb to size your air conditioner, but rules of thumb can overestimate the size needed. A good contractor will use a design load calculation to size a central air conditioner to your home. The contractor will need to check the following six factors.
How well your house is insulated
How well air leaks are sealed
How well your ducts are sealed and insulated
The size, type and number of windows and the direction they face
Shading provided by overhangs and landscaping
The size, layout, and orientation of your house
