Why would ac cause engine to increase in rpm’s? Your rpms rise when you turn on the AC because the AC compressor starts spinning. This takes a little bit of power from your engine and that means it needs to spin a little faster to keep the engine running.
When my AC is on my rpms go up and down? The exact cause of the issue had been found to be that of a loose alternator belt. When the engine was cold, the alternator had a slack in it and if the AC load is added on the engine, the rpm fluctuated. Solution was simply to tension the alternator belt.
Does AC affect engine rpm? When the A/C is switched on the engine ecu increases the idle speed by a few hundred rpm to make sure the engine does not stall and keep a “smooth” idle. This is normal.
Why does my engine get loud when I turn on the AC? Your engine is under a heavier load when you run the AC. … So if you turn on your AC and hear a rattle, it may mean you have a failing or bad: AC compressor. Rattling or your car air conditioner making loud humming noises which get worse as you accelerate can both be signs you need to replace your AC compressor.
