How to replace the condenser on an AC unit?
Remove the compressor. Look carefully at the high and low side lines…if there are particulate, black residue or grey matter, replace the condenser too. If not, remove the plug on the LH side bottom of the filter/dryer attached to the condenser. Pull out the desiccant bag…if it is full of metal particulate, replace the condenser.
Is there a warranty on replacing a condenser unit?
No Warranty – Mismatched systems can cause problems. Therefore, the manufacturer may exercise the right of not extending a warranty if you replace the condenser unit but not the evaporator unit. Premature Failure – Mismatched units can cause uncalled for pressure on one or both the units.
Why do I have to replace the compressor and the condenser at the same time?
If the original condenser isn’t replaced, the risk is that a small piece of debris that’s left behind in the original condenser will cause the compressor to fail again. Therefore, many replacement AC compressor warranties require replacement of the condenser…which is probably why your mechanic is telling you to replace both parts at the same time.
Can a condenser and evaporator coil be replaced?
Well, it’s not always that easy. In some situations, replacing just the evaporator coil means it will “mismatch” your condenser (the outside unit). And if the condenser and evaporator mismatch in either age, SEER or refrigerant, you’re going to run into problems like:
When to replace a condenser in an AC system?
At 0psi it is relatively neutral to the outside air and will not suck contaminants into the system when you open it. When you go to replace the condenser if mounts are bent/broken it is going to be a pain just a heads up. Anytime you open an a/c system it is recommended you replace the receiver/dryer or accumulator.

Can you replace the refrigerant in an AC unit?
Additionally, older systems that used R-22 refrigerant (the standard in AC systems a couple of decades ago) should be upgraded to R-410 refrigerant in order to uphold federal environmental protection legislation. This can be a time consuming, costly process that simply isn’t worth saving on a new indoor unit.
When to replace a compressor in an AC unit?
The compressor is still under warranty such that you only need to pay for the labor cost. No other major components of your AC have already failed or are likely to fail in the near future. The inside unit was replaced recently. Budget is tight, and you can’t be extravagant. 2. Buy a new air conditioner only if one or more of these terms are met –
