We repair most systems, even if we did not install them. If your system is not covered by a warranty, we charge $50 an hour for service work. We will contact you to schedule a convenient day and time to conduct repairs. A technician might call you prior to arriving to confirm the problem you are experiencing so he can arrive with the correct equipment, parts, and crew. Payment is due on completion of service unless other arrangements have been made. Please call 555-2610 to arrange a service visit.
