Hvac company ripped me off on repair?

I got charged $1400 to install a $100 fan motor that only took the tech an hour to install. This is a rental property so at the time I was like let's just get the ac back on for the tenants, now two weeks later I'm like man I was way overcharged. $800-$900, fine but $1400? I get that everything is marked up etc, but still. I've seen several complaints online about how the same company overcharged others also. I'm going to call them and be like wait a minute now, you guys need to credit me back some money here. Opinions? I suppose I could dispute the credit card charge, but I think that only works if it's a fraudulent charge.
