noisy A/C

As we slowly come down from this ridiculous heatwave, I noticed that my A/C was VERY loud today (I've never noticed this amount of noise during the 7 weeks that I've had this car -- and I regularly use my A/C). The noise was much louder outside of the car. Has anyone else experienced this or know if this is normal due to the high temps of late?

Just to clarify and differentiate from another thread: My A/C cools my car quickly. My concern is just the newly loud noise, not the cooling ability.
