A gas heater and electric air conditioner are in the same cabinet. A. The inspector will not
operate the air conditioner in the cooling mode if the outside air
temperature is below 60 degrees to do so may damage the system even
though there are safety devices installed which should prevent any
damage. B. Be aware that the inspector does not test the uniformity or
adequacy of cooling air supply to the various rooms or at individual
registers. C. The inspector does not determine whether the size of the
air conditioner is appropriate for the house. One ton of air
conditioning per 600 sq. Ft. Of area is a good rule of thumb but each
building and each geographical area may have differing requirements. If
these limitations concern you it is recommended you contact an air
conditioning contractor for further information.
