I recently have been having issues with my A/C unit on my Condo which was built in 1986. This unit might very well be the original A/C unit. It has two components, the fan outside and the air handler in the attic. I had the A/C maintenanced last summer and was told it was leaking Freon. They filled it up to spec but told me it would just continue leaking, which it has 1 year later.
Company A (big A/C company) told me to replace the whole unit because the fan was going to go out soon and both components are leaking freon, he didnt actually check for a leak, and gave me a quote for a 2 ton A/C for a 900 sqft condo costing about $5100 for unit and install with warrenty.
Company B (mom and pop shop A/C company) told me the leak is most likely in the Air Handler, just a guess and still needs to check, and they can replace just that part of the system for about $2000 while replacing the fan's capacitor and other parts for about $100.
I have a lot going on this year and would not like to dip into savings to fix so option b looks better and while I would rather replace the whole thing, I wanted to know if what Company B told me is true, I can replace just the Air Handler and not worry about the fan till later, which he said was in decent shape.
