The “worry-free” maintenance plan from Rainbow Mechanical

While 24/7 service capacity is ideal in an emergency situation, we strongly recommend a preventive maintenance plan to keep systems at peak performance, while forestalling potential operational issues. Comprehensive maintenance offers far-reaching benefits.

•  minimizing down-time for equipment and staff

•  reducing demand for any unexpected repair costs

•  improving long-term capital equipment planning

•  extending equipment life/controlling expenses

•  ensuring consistent tenant comfort/satisfaction
