Diagnostic Fee! Barnes HVAC Services charges from $69 to $165 to diagnose your system. The price depends on the complexity of the system, the difficulty of accessing the equipment, and the customer’s service address. Commercial equipment is typically more expensive than residential equipment to service and repair.
