Preventive Maintenance

It is Air Leaders Inc. goal to ensure that our clients obtain the maximum life of their equipment, keep operating costs at a minimum, and avoid costly emergency breakdowns. An effective Preventive Maintenance Program is key.

Preventive Maintenance starts with a thorough inspection using a systematic method of factory-prescribed checks of the operating system, safety, controls, refrigeration system, and accessories to provide a condition report for each piece of equipment. This information provides the basis for informed decisions on repair work and maintenance required to ensure equipment is safe and operating at peak efficiency.

We offer monthly, quarterly, semi-annual and annual service contracts. Please contact us to learn more.

Protection Plans

A protection plan provides parts and labour coverage for your equipment, helping you avoid expensive and unexpected repair costs when things go wrong. A breakdown always happens when you least expect it and can be very costly. We only use genuine manufacturer’s part and never universal parts. Please contact us to learn more.
