NMS strives to provide top service in the industry and eliminate your maintenance costs. Unlike other refrigeration service companies, we offer no parts or labor charges while under our annual service plan. This means no cost to you as a customer for any parts we replace or service calls during the contract period.

In turn, timely maintenance will prevent indoor air pollution, unnecessary repairs and undue equipment breakdown, and as a result, safeguard you against wasteful financial expenditures in the long run.

Clean indoor air environment is especially important for high occupancy/traffic and special needs facilities, such as educational premises, day care centers, hospitals and around the clock places.
