I need to replace an 11 y.o. 2.5 ton Carrier condensor. The HVAC person that declared it dead said that I didn't need to replace the evaporator coil, just the get a new 2.5 ton condensor. However, after reading online about this, I am afraid that 'saving' the cost of the evaporator coil now will cost me in the long run if it fails after 2010. So, my questions on this are:
- Should I replace the condensor now with a cheap, 2 year old, 2.5 ton used unit I can get from Craigslist, and later when the evaporator coil fails, replace the whole system with new R410 units?
- Should I bite the bullet and change over to R410 now (even though I can barely afford it)?
- If I change over to R410 now, I want to make sure I have the right sized system. I have read that a 2.5 ton system is good for up to 1800 sq ft. I have an older, 2000 sq ft home. Is a 2.5 ton system undersized for my home?
- Finally, is Goodman a good brand? They have a 10 year warranty, but I have never heard of them, but I have only heard of the ones that advertise alot.
