Had bay area at my house. Very professional. They only don't change for new installation estimates. They do charge for a service call and or diagnostic. Very reasonable.
Call them to ask. Not sure. They do offer contracts for service for very affordable annual cost.
We do top notch, Annual Test, Tune and Cleans that can detect issues and prolong equipment life. They are discounted in the slow season, October through February, so taht's the best time to have tehm done.
