Recommended A/C Compressor for a 1525-1550 sf Home?
On June 30th, I had my compressor cleaned and had the A/C technician check-up, to see why my house that will be 4 yrs old in Nov. (I would have been in the house for a year in March), did not seem as if it was cooling with the thermostat set on 75 degrees. The technician did a leak check and did not find that there was a leak. He recommended that I add freon, because he said that it was low. I told him no, that I would wait until the home warranty technicians come and check the unit. He came back and told me that he added a little freon for me since, the temp was hot and he did not want to leave 3 women in a hot house (Added the freon without my permission or knowledge).

Home warranty technician came today, stated and recommended the following:
Found Freon levels to be reading very high on gauge. Checked TXV for proper operation, all OK there. Found A/C unit undersized for this 1550 sf home. Only a 2 1/2 ton system, should be at least a 3 ton system. Compressor is not operating properly due to four years of overworking itself. Home warranty company denied claim due to undersized unit.
Inspected duct work in the attic. No mechanical failures found. Ductwork in good condition.
Then gave me an estimate of replacing the system to a 3 ton unit. Which I clearly can not afford, to pay this out of pocket. This is why I have a home warranty.

What is the standard recommendation for a home my size. I was told by 2 other technicians that it is 1 ton per 600sf. The technician with the estimate said, 1 ton per 500sf. Also, he said that the system should still be under warranty because it is less than 5 yrs old, through the builder or manufacturer. I have contact the builder, becase the previous owners left that information, I contact the home warranty company and they are sending someone to do a 2nd opinion. Should I contact carrier, the manufacturer,as well? I am single and truly do not have the money, even if a payment plan was set-up.
Thank you for your assistance.

Is there a recommended tonage amount per square feet?
