Commercial HVAC Preventive Maintenance Contracts
Commercial and industrial HVAC preventive maintenance contracts for chillers, RTUs, boilers, and refrigeration in Chicagoland, Northern Illinois & Indiana.
What this covers
Scope
- We build commercial and industrial preventive maintenance contracts covering rooftop units, chillers, booster chilling systems, boilers, refrigeration, and BAS controls.
- We execute seasonal cooling and heating startups, coil and heat-exchanger cleaning, filter changes, belt and bearing service, and electrical checks.
- We inspect refrigerant circuits, burner safeties, condensate drains, economizer dampers, and control sensor calibration on a scheduled cadence.
- We document equipment condition and developing wear items so facility managers and property managers can budget repairs before breakdowns occur.
Problems we solve
- Fouled coils, worn belts, neglected burners, and clogged drains cause avoidable mid-summer cooling failures and mid-winter heating lockouts.
- Seasonal drift across chillers, rooftop units, boilers, and BAS controls wastes energy and erodes heating and cooling capacity.
- Run-to-failure operation creates unpredictable repair spikes that disrupt facility budgets during peak weather.
- Skipped mechanical service shortens the operating life of capital chillers, boilers, rooftop units, and refrigeration plants.
Service modes
How we work it
24/7 emergency
When unexpected faults arise between scheduled visits, our around-the-clock emergency service dispatches technicians to the equipment already on your contract.
Planned work
We schedule repairs and phased retrofits for deficiencies uncovered during preventive inspections around tenant hours and plant shutdown windows.
Maintenance
Recurring contract visits align task checklists with each asset type and seasonal changeover across your Chicagoland, Northern Illinois, or Indiana facilities.
In the shop
If an inspection turns up corroded ductwork transitions, damaged exhaust hoods, or specialized cooling needs, our in-house fabrication shop builds custom replacements.
FAQ
Questions facility managers ask
What equipment can be consolidated under a preventive maintenance contract?
A contract can cover rooftop units, air-cooled and water-cooled chillers, booster chilling loops, boilers, commercial and industrial refrigeration, exhaust ductwork, and BAS controls. Consolidating those systems with Pro Tech Contractors gives facility and property managers consistent documentation across the entire mechanical plant.
Can you manage preventive maintenance across sites in both Illinois and Indiana?
Yes, Pro Tech Contractors is licensed in both Illinois and Indiana and dispatches crews from Lombard across Chicagoland, Northern Illinois & Indiana. We can write preventive maintenance contracts across more than one building.
How do preventive maintenance visits help with capital planning?
Technicians flag aging heat exchangers, compressors, vessels, and aging refrigeration systems before they fail under peak weather or production load. Early visibility lets facility teams plan retrofits and replacements on budget rather than reacting under emergency conditions.
