Not a pro, just a homeowner. Have had various problems with my 5 (?) ton Carrier unit over the last few years (bad capacitor, wiring problems, float switch problems, zone control board problem, pan overflows, freon refills, etc.) Had a leak test conducted today and the technician said my a-frame style coil is leaking. Looking at it myself, it's pretty rusted and I just had to clean a bunch of rusty stuff out of the pan below the coil (that I think was also causing a clogged condensation line).
I really know next to nothing about HVAC, so I'd love some help.
1) Shouldn't a coil last longer than 6 years? My home was built in late 2003 and that's when the unit was installed. It's a zone controlled (Duozone controls), 5 ton, furnace/AC combo type system.
2) What is a ballpark price for something like this? I'll have a formal quote tomorrow, but the tech said probably around $1000.
3) With the tax credits and such, should I look at replacing everything with a whole new A/C system?
Your help/advice is much appreciated.
