Ford knows there is an issue with early Focus's.

TSB 14-0073 AIR CONDITIONING (A/C) COMPRESSOR NOISE HEARD INSIDE THE VEHICLE CABIN - Maintenance, TSB's & Recalls - Ford C-MAX Hybrid Forum

The C-Max and Focus share a lot of the same parts. Mine has been making weird noises as of late too but still blows ice cold.

About a year after I owned my 2014 Focus SE I started having similar AC issues that others have experienced on this AC thread. If I'm already driving the car and turn on the AC no cold air will blow out, it's just kind of humid air. In order to get it to blow cold air I have to pull over, turn off the car, and restart it. Then cold air blows out. Also, if I start the car and turn on the AC and get cold air, then turn off the AC while driving, then turn the AC back on it only blows humid air. I used to be able to get it to start blowing cold air again while I was still driving if I messed around with the heat and AC switches for a minute changing it from AC to heat back to AC, but that doesn't work anymore. So currently I have two options, 1. I have to turn on the AC when I first start the car, and leave it running, or 2. if I forget to turn on the AC when I first start the car, then I have to turn off the car at a traffic light or pull over and turn the car off, then turn on the AC and start the car.

Isn't the C-Max closer to the Fusion hybrid than the Focus? If so, that C-Max compressor is electric - not belt driven. However, that doesn't mean the internals aren't the same.

Body/Chassis wise no, the C-Max is closer to the Focus than the Fusion, however power train wise the 2.0L Atkinson cycle PFI gasoline engine and electric motor set up are more closely aligned with the Fusion hybrid that shares a very similar power train set up.

From an A/C stand point I would suspect that however it is an electrically driven compressor on the C-Max hybrid because of the reduced energy usage.

I believe the reason for electric driven compressor is that the engine shuts off when in EV mode. Engine shuts off (not idles, but off), compressor would cease turning.

Kind of neat on my Fusion hybrid to remotely start the vehicle and have it start cooling the cabin all off the high voltage battery.

That is one possible reason along with the electric compressor being more efficient/ drawing less load off the engine as long as it's load can be accommodated by the alternator and or high voltage battery system vs drawing a load directly off the engine. It is more critical on the PHEV than the HEV that it be decoupled from the engine due to the fact that the PHEV can be driven without the gasoline engine for extended distances (20+ miles instead of less than 2 miles of EV only operation)

I have a 2013 Focus and I have the same issues. However, mine takes forever to get the AC to blow cold. I have to be driving continuous with no stopping for about 10 miles before it starts blowing super cold. Granted I do live in El Paso TX and temperatures have reached 100+. But if im making a short run or am in stop and go traffic its miserable.

You have a black car buddy in a hot area. I have a 2010 black Ford Focus the air is worthless when it's 90 degrees with the sun beating on it. It takes a tremendous amount of energy to cool off all that heat and deal with the sun load.
