HVAC emergency in Chicago? Call Bernie's Heating & A/C Service now! Same-day service available for all heating and cooling emergencies.
Restaurant & retail commercial HVAC services keep guests comfortable and equipment running reliably in busy business environments.
We've worked on 100+ Chicago restaurants and retail stores since 2008. A failed AC during July dinner rush costs $5,000 in lost sales—we understand the revenue impact of downtime.
Restaurant and retail HVAC isn't just "bigger residential." The demands, stakes, and requirements are completely different.
Residential: 24/7 occupancy, lighter daily use
Commercial: Restaurants/retail run 12-16 hours/day at maximum load. Different wear patterns, extended equipment stress.
Result: Commercial equipment wears faster and needs more frequent maintenance
Residential: 4-6 people in a home
Commercial: 50-200 people in a restaurant or retail store. Massive heat load from body heat, constant door opening (air infiltration), humidity control challenges.
Result: Commercial systems need higher capacity and better ventilation
Residential: Discomfort, inconvenience
Commercial: $2,000-10,000/day in lost revenue. July dinner rush without AC = customers leave. Holiday shopping without heat = closed doors.
Result: Emergency service is about protecting revenue, not just comfort
Residential: Basic safety standards
Commercial: Chicago health code (restaurants need makeup air, grease exhaust), ventilation rates (15 CFM/person dining, 100+ air changes/hour kitchen), fire code (grease duct cleaning every 3-6 months).
Result: Permits, inspections, and compliance documentation required
Restaurants have the most complex commercial HVAC needs—kitchen heat loads, grease exhaust, makeup air, and Chicago health code compliance.
Grease Exhaust Hoods:
Chicago code requires Type I hoods for cooking (grease-producing). Must exhaust outside, include fire suppression, and get cleaned every 3-6 months (fire code).
Makeup Air Units:
Replace exhausted kitchen air to prevent negative pressure. Without makeup air, dining room doors get hard to open, draft issues, and HVAC struggles to maintain temperature.
Kitchen Heat Load:
Commercial ranges produce 50,000-100,000 BTU of heat. That's like adding 4-8 furnaces running full blast during dinner service. AC systems must handle this load plus dining room cooling.
Grease Buildup:
Grease vapor coats HVAC equipment (rooftop units, ductwork). Requires quarterly cleaning beyond standard maintenance to prevent fires and equipment failure.
River North Restaurants:
High-rise buildings, rooftop units 10+ stories up, limited access, crane requirements for replacements. Premium image means AC failure is unacceptable during dinner service.
Lincoln Park Storefronts:
Old buildings (1900s-1920s), ductwork retrofits challenging, tight mechanical rooms, historical building restrictions. Creative solutions needed.
Loop Downtown:
Multi-tenant buildings, shared HVAC systems, coordination with property management, building engineers. Permits and scheduling headaches.
Pilsen/Bridgeport:
Standalone buildings, easier rooftop access, older equipment common. Good candidates for full system upgrades vs patching old units.
Chicago Department of Public Health inspections: Restaurants get surprise visits. HVAC failures (inadequate ventilation, improper exhaust) can result in citations or closure.
Required ventilation rates: Dining areas need 15 CFM per person. Kitchens need 100+ air changes per hour. We calculate and document compliance.
Grease duct cleaning: Fire code requires every 3-6 months depending on cooking volume. We don't do the cleaning but coordinate timing with your duct cleaners.
Retail stores have different challenges than restaurants—high foot traffic, variable occupancy, extended hours, and customer comfort drives sales.
Magnificent Mile:
High-rise retail, premium image (AC failure = lost sales + angry high-end customers). Fast response critical during Michigan Avenue shopping season.
Wicker Park/Bucktown Boutiques:
Small spaces (500-2,000 sq ft), tight budgets, accessible rooftop units. Good for ductless mini-splits and small RTUs.
Neighborhood Strip Malls:
Standalone storefronts, accessible rooftop units, easier maintenance access. Most cost-effective for service and replacements.
Uncomfortable customers don't buy. Studies show retail sales drop 20-30% when stores are too hot or too cold. Your HVAC system protects revenue—we treat it that way.
From preventive maintenance to emergency repairs to full system replacements—we handle all commercial HVAC needs.
Monthly Plans: $300-1,500/month
Small retail (under 2,000 sq ft): $300-500/month
Medium restaurant/retail (2,000-5,000 sq ft): $500-800/month
Large restaurant/retail (5,000+ sq ft): $800-1,500/month
What's Included:
Why businesses need it: Prevents downtime during peak hours (dinner rush, holiday shopping). A $5,000 revenue loss from AC failure costs more than a year of maintenance.
Response Time:
2-4 hour goal for restaurants/retail (revenue protection). Maintenance contract customers get priority—you skip the line during polar vortex/heat waves.
After-Hours Pricing:
No markup—same $150 diagnostic as residential. We don't price-gouge businesses in crisis. Repair costs are parts + labor, regardless of day/time.
Common Emergencies:
Typical repair range: $300-2,000 depending on component. We quote before starting work—no surprise bills.
Rooftop Units (RTUs):
Most common for restaurants/retail. 3-20 ton capacity.
5-ton unit: $6,000-10,000 installed
10-ton unit: $10,000-16,000 installed
15-ton unit: $14,000-22,000 installed
Split Systems:
Small cafes, boutiques, offices. $3,000-12,000 installed depending on size.
Grease Exhaust Hoods:
Kitchen ventilation (Type I hoods for cooking). $3,000-8,000 installed including ductwork and roof penetrations.
Makeup Air Units:
Replace exhausted kitchen air. $2,000-10,000 installed depending on CFM capacity.
We're upfront about costs because businesses need to budget. These are typical ranges—actual quotes depend on equipment age, location, and access.

"We'll tell you if repair makes sense vs replace. A 15-year-old rooftop unit with a failed compressor? That's $3,000 repair on equipment worth $4,000. We'll recommend replacement and explain why—you decide."
"No upselling commercial-grade equipment when residential-grade works. Small boutique with 2 employees doesn't need a $15,000 VRF system when a $4,000 mini-split does the job."
"We work around your business hours—install during closed hours (nights, weekends, Mondays for restaurants) to avoid disrupting customers. No markup for after-hours installation."
Example: The $5,000 Mistake
River North restaurant. AC dies during July Saturday dinner rush (95° outside, 85° inside dining room). Customers leave, reservations canceled. Lost revenue: $5,000 (250 covers x $20 average). Emergency repair: $800 for compressor replacement.
Prevention: Quarterly Maintenance
May tune-up catches failing compressor (capacitor weak, amp draw high). Replace for $1,800 during slow Tuesday lunch. No lost revenue, no customer complaints. Maintenance contract: $600/month x 12 = $7,200/year. Cost of one AC failure: $5,800 (lost revenue + repair). Prevention pays for itself.
Commercial HVAC work requires permits and inspections. We handle the paperwork—you focus on running your business.
Most common for restaurants (5-20 tons). Self-contained heating/cooling, installed on roof. We service all major brands (Carrier, Trane, Lennox, York, Rheem).
Small cafes, coffee shops, fast casual. Outdoor condenser + indoor air handler. Good for spaces under 2,000 sq ft or supplemental cooling.
Type I (cooking/grease-producing) and Type II (non-cooking). Must exhaust outside, include fire suppression, cleaned every 3-6 months per Chicago fire code.
Replace exhausted kitchen air (prevents negative pressure, door issues, draft problems). Required by Chicago code for hood exhaust over 400 CFM.
We service HVAC-related issues (evaporator coils, condensers, airflow). Not refrigeration compressor specialists—we refer those to commercial refrigeration contractors.
Small restaurants, wine bars, private dining rooms. Quiet operation, zone control, no ductwork needed. $3,000-8,000 installed.
Small retail (under 2,000 sq ft): $300-500/month. Medium restaurant/retail (2,000-5,000 sq ft): $500-800/month. Large restaurant/retail (5,000+ sq ft): $800-1,500/month. Plans include quarterly tune-ups, filter changes, priority emergency service, and 20% parts discount.
