Completed with ac 2 on 2005 trane main downstairs 3.5 ton r22 and 2010 trane upstairs 2.5 ton both gas horizontal in attic. Both cooling at this time of check up but found issues with both. Upstairs has water on a very rusted secondary drain pan due to bent inside pan, downstairs compresor running amps are very high with weak capacitor and both fan motors showing wear. Gave the option to do all preventative repairs, minimum repairs or complete unit upgrade for downstairs or both. Customer is not interested on anything.
