Service technicians have the skills and tools to quickly diagnose the problem, offer the right solution and get your equipment up and running in no time. DeMark Home Ontario’s preventative maintenance programs will assure customers of fewer breakdowns and problems and extended life time of the equipment by eliminating small problems before they escalate to extensive and expensive repairs. Waiting for equipment to break down is very costly.
