Not sure if I should post here, or a pro forum.
I have a PTAC in a sunroom that was installed in the house in 2003, before I bought it. it's a friedrich. I've posted here before about trying to wire a remote programmable stat to it, and it can't be done....easily.
Yesterday, I turned the unit on, it started cooling the room rapidly, and then I started smelling something between ammonia and citrus, and then the room got warmer and warmer. It sounds like some seal or something let go. it sounds at least as though the compressor is still running, just no coolant moving through.
The situation is, I have a home warranty till Sept. I am about to call them about this issue. I know it'll cost me 60 to have them come out, but they will fix it or replace it. I don't know if the issue is severe enough to consider it a replacement or if they can fix it for a hundred bucks.
I'm an HVAC engineer, and have some contact to prob buy a new unit at near cost, IF they will agree to pay me off for the unit in lieu of repairing it. However, I have no idea who they use for repair and if i have a contact there.
I guess, my question is, does anyone familiar with these units have a guess as to whether this is likely a simple fix, or if I should attempt to make arrangements to replace it.
aka, if their repair guy says they can fix it for 100, I'll pretty much be stuck there. If their repair guy says repair will be 400 and they will replace it, then I'd rather take their 400, and attempt to buy one through a contact at cost (paying the additional) and get a very quiet unit with a programmable stat. (This one is rather loud.)
Also, the prices listed are pure guesses and in no way indicate a price quote of any kind.
