Maintenance Program

A truly different approach to providing maintenance services

ASSC maintenance experts assist you in strategically planning your maintenance within your budget. Our Professional Maintenance Engineers (PMEs) are highly trained to assist you in making informed, calculated decisions, using our emPlan (engineered maintenance) software. With it, you and our experts can collaborate to produce a maintenance program that measurably impacts your mechanical equipment, occupants, and buildings.

Proper maintenance affects energy efficiency, life-cycle costs, and tenant comfort

Your budgets are strategically planned and applied on a unit-by-unit basis. They focus on areas that most impact critical, high-cost HVAC and less, low-priority equipment.

ePlan with your PME

What is an ePlan?

ePlan is an effective maintenance strategy and software that focuses on measurement and planning. With it, maintenance buyers and account managers  rationally pre-plan the exact tasks to be performed, and more importantly determine the required time for techs to fully and safely complete the tasks. Once planned, price and delivery are clear.

No intended missed promises occur here – just concise information to make decisions on, and for the techs to perform exactly what was planned and promised.
