We own a small condo that we bought a few years ago. The original in-wall air conditioning condenser/compressor died at the end of last year and now I need to replace it. Thankfully, the natural gas furnace and evaporator coil were both replaced before we took ownership of the unit, so that's good.
One of the local HVAC companies quoted me around $Xk to replace the condenser with a new on-ground unit. Since we're trying to buy a house this year and spending that much money to fix the a/c in a unit that we probably won't be able to sell anyway (in 6 months we've had three showings) just isn't possible for us. What I'd like to do is buy the materials and then find someone who knows what he's doing to do the labor - I think I've got both lined up now, but want to make sure on the parts/equipment end.
I'm currently looking at a couple of new condensers but I want someone with some real HVAC knowledge to weigh-in, please.
Currently, our coil is a Carrier CD5AXA024014ABAA (I found detailed info on it here, which is from here). It shows that it's a 2 ton model that can take either R-22 or R-410a refrigerant. On the coil's label it reads:
- 450 PSIG
- kPa 3102
- R-22 and R-410a with listed unit
- Listed 3R39 refrigerant evaporator
The two new a/c condensers I'm looking at are:
1. Goodman GSC130241, 2-ton 13 SEER, R-22
2. Goodman GSX130241, 2-ton 13SEER, R-410a
My questions are:
1. Am I understanding the model number of my evaporator correctly and that it is in fact a 2-ton unit?
2. Are the two condenser units listed above actually compatible?
3. Someone in the HVAC world told me that as long as the tonnage and the refrigerant types matched then they are in fact compatible true?
4. How hard (and what's involved) in converting our coil to accept R-410a since it currently uses R-22? Is it worth it? Should I just buy the R-22 condenser?
5. Aside from the line set/refrigeration tubing, what else will I need to buy?
Thanks so much for any help anyone can provide me!
