Price for central air maintenance?

Categories: A/C

We have a central air and heat system in our four-story brownstone. The company that installed the system has just quoted us a price of $1,200 for annual maintenance of the system (e.g., replacing filters, making sure there is adequate coolant, etc.). Does this strike people as high, and if so, what is a more reasonable price? And if you have recommendations for companies who do this type of maintenance work, it would be greatly appreciated as well.
