Of course, and there are NO charges. We have technicians who are on call to field calls outside of normal business hours. Call our main telephone number (888-628-2800), explain your situation to our answering service, and they will contact the technician who is scheduled to field calls after hours. The technician should be in touch with you within 20 minutes. Again, there are never any charges to speak with a technician, regardless of the time of day.
