Question

Which of these is least likely a step in replacing a failed compressor?

Answer 1

Answer:

D. Inspecting the muffler

Explanation:

HVAC/refigeration systems are sealed systems that use refrigerant not combustion. A muffler is found on combustion systems.

You would disconnect,  flush, seal, and possibly replace the condenser if the condenser is found to be failing.

Answer 2

Answer:

C. Replacing the condenser is least likely a step in replacing a failed compressor.

Explanation:

To answer the above question, we need to understand the work of Air-cooling systems. There are 2 main units, compressor and condenser. Compresser and condenser are connected by the airtight pipe, and the required gas is injected in the system.

Compressor compresses the gas, compresed gas moves to condenser, condenser cools the gas, and the gas is expanded again, and then heat transfer takes place in indoor unit. Again the compressor compresses the gas, and process goes on.

So here, compressor is failed, so we need to inspect the muffler first of all to detect the issue, and definitely we need to remove all the gas from the system which means flushing the system, also hoses and other valves needs to be disconnected. However, replacing the condenser doesn't seems to be required to replace the failed compressor, as both are totally different units.
