Downtime Is the Real Cost
A failed rooftop unit on a hot Saturday doesn't just cost a repair — it costs a closed store, spoiled inventory, or a building full of uncomfortable tenants. Preventive maintenance is cheaper than any of that.
Ironclad's programs are built to eliminate surprises: scheduled service, priority response, and capital planning so aging equipment is replaced on your timeline, not at the worst possible moment.
- ✓Preventive maintenance beats emergency repair
- ✓Priority response keeps you open
- ✓Capital planning for budgeted replacements
- ✓One partner across all your locations
Chicago Facilities on Ironclad
Ironclad has held our maintenance contract across six retail locations for four years. Zero unplanned downtime, quarterly reports we actually understand, and when a rooftop unit failed on a Sunday they had it running before we opened Monday. Exactly what a facilities partner should be.
Our restaurant's kitchen make-up air and walk-in refrigeration are life-or-death for the business. Ironclad keeps both dialed and answers the phone at 2am. Professional techs, clear invoicing, no drama.
They retrofitted our 1920s office building's HVAC with modern controls and building automation. The energy savings were real and documented, and the tenants stopped complaining about hot-and-cold floors. Genuine commercial expertise.
Commercial HVAC FAQs
Do you handle multiple locations?
Yes — multi-site facilities are a core part of what we do. We run preventive-maintenance programs across retail chains, restaurant groups, and office portfolios with unified reporting and one point of contact.
What's included in a maintenance contract?
Scheduled PM visits (typically quarterly), priority emergency response with guaranteed times, documented reporting, warranty tracking, and capital-planning advice so equipment replacements are budgeted rather than sprung on you.
How fast is your emergency response?
For contract clients, response is prioritized with guaranteed times — a real commercial tech rolls out any hour, including nights, weekends, and holidays. Commercial downtime is expensive, and we treat it that way.
Do you service rooftop units and refrigeration?
Yes — packaged rooftop units (RTUs), air handlers, chillers, VAV systems, building controls, and commercial refrigeration including walk-ins and make-up air. Commercial systems are our whole business.
Can you modernize an older building's controls?
Absolutely. We retrofit legacy systems with modern building automation (BAS) for better comfort, tenant satisfaction, and documented energy savings — often with attractive payback in older Chicago buildings.
Are you licensed and insured for commercial work?
Yes — fully licensed (Chicago HVAC Lic #C-14827), bonded, and insured for commercial and light-industrial work. We carry the coverage and certifications facility managers require.
