I have a Trane model YCC024F1L0BE manufactured on 07/1999 that stopped heating on Christmas Eve. I called out a tech yesterday and he inspected the unit. The on board diagnostic LED would flash three time when the thermostat called for heat which indicated a bad valve.
When the tech tapped on the diaphragm that is connected via a vacuum hose to the exhaust blower, the burner lit-up fine. So we though I might get away with a part that costs less than $X00.
When the fire box got hot enough, the blower kicked-on, and we noticed another problem. The steady "after burner sound" changed to what sounded like a someone blowing on the burner... kind of a puff-puff sound. The tech took a closer look and, and showed me where the flame from the burner was rolling-out. It wasn't rolling-out much, but the tech advised me that I had a potentially dangerous fire and CO situation, and not to run to heater until it was either replaced or fixed. He also told me that I had a bad heat exchanger.
The tech said that I would be better off replacing the unit because who knows what would go next (I have noticed the A/C compressor is quite noisy), and I would have a warranty not to mention a more efficient heating and cooling unit.
Question: Given the unit is 8 years old, is it better to take the tech's advice, and get a new unit, or would I better off spending over a grand and replacing the parts that need to be replaced?
Is the Trane YCC024 a good unit, and I'm just unlucky, or is it a trouble maker that I'd just end-up soaking money in to.
The tech recommends a 13 Seer 2 Ton Gas Package. He did not write down a model number, but after some searching, it looks like he means the Rheem RRNAB024. I noticed there is also a RRNL-B and RRPL-B which are the next steps up.
Is the RRNA good, or would I be better paying a little more for the RRNL-B or RRPL-B.
Or should I just bite the bullet and go for the RQPW (Hybrid) which is what I'd really like to get. My electric here is $0.07/kWh, and natural gas is $1.61/Therm. Would it be worth it?
Finally, is Rheem a good unit? I know, Ford, Chevy or Toyota, but I guess I mean to say is there any reason I should look harder at a Rheem than say, another Trane, or Carrier, or Bryant, or Lennox, or whoever?
Any advice welcome!
