Why Commercial HVAC Is Different

Restaurant and retail HVAC isn't just "bigger residential." The demands, stakes, and requirements are completely different.

Operating Hours

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

Occupancy Density

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

Downtime Cost

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

Code Requirements

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

Restaurant HVAC Challenges (Chicago-Specific)

Restaurants have the most complex commercial HVAC needs—kitchen heat loads, grease exhaust, makeup air, and Chicago health code compliance.

Kitchen Ventilation Requirements

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.

Chicago Restaurant Locations We Work

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.

Health Code Compliance

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 HVAC Challenges

Retail stores have different challenges than restaurants—high foot traffic, variable occupancy, extended hours, and customer comfort drives sales.

High Foot Traffic

  • Constant door opening = air infiltration, humidity control challenges
  • Variable occupancy: 10 people at noon, 100 people at 5pm (HVAC must handle swings)
  • Display window heat gain: South-facing glass = solar load (AC fights the sun all day)

Extended Operating Hours

  • Retail open 10am-9pm = 11-hour days (HVAC runs longer than residential)
  • Weekend/holiday operation: No "time off" for equipment (Memorial Day-Labor Day heat, Black Friday-Christmas cold)
  • Seasonal peaks: Holiday shopping = maximum load when you can't afford failure

Chicago Retail Locations We Serve

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.

Commercial HVAC Services We Provide

From preventive maintenance to emergency repairs to full system replacements—we handle all commercial HVAC needs.

Preventive Maintenance Contracts

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:

  • Quarterly tune-ups (seasonal inspections before heating/cooling season)
  • Filter changes (monthly or quarterly depending on environment)
  • Refrigerant checks, coil cleaning, belt replacements
  • Control calibration, thermostat programming
  • Priority emergency service (you skip the line if equipment fails)
  • 20% parts discount on all repairs

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.

Emergency Repair (24/7)

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:

  • Compressor failure (AC won't cool, unit running but no cold air)
  • Refrigerant leaks (frozen coils, inadequate cooling, high electric bills)
  • Control board failures (unit won't start, erratic cycling)
  • Blower motor burnout (no airflow, overheating, loud noises)

Typical repair range: $300-2,000 depending on component. We quote before starting work—no surprise bills.

Equipment Replacement

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.

Ductwork & Ventilation

  • Grease duct cleaning: Required every 3-6 months per Chicago fire code. We don't do the cleaning but coordinate with your duct cleaners.
  • Ductwork installation/modification: Build-outs, tenant improvements, adding zones. $2,000-15,000 depending on scope.
  • Ventilation upgrades: Meeting Chicago health code for permits (restaurant remodels, change of use). We calculate CFM requirements and design compliant systems.

Commercial HVAC Pricing (Transparent)

We're upfront about costs because businesses need to budget. These are typical ranges—actual quotes depend on equipment age, location, and access.

Honest Assessment

"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."

Maintenance Prevents Disasters

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.

Chicago Commercial Permitting

Commercial HVAC work requires permits and inspections. We handle the paperwork—you focus on running your business.

When You Need Permits

  • New equipment installation: Yes ($200-500 permit + inspection from City of Chicago Department of Buildings)
  • Rooftop unit replacement: Yes (Chicago requires permit for all roof work, even like-for-like replacements)
  • Ductwork modification: Usually yes (if structural penetrations, adding zones, or changing CFM capacity)
  • Emergency repair: No (like-for-like component replacement exempt—compressor swap, blower motor, etc.)

We Handle Permits

  • File with City of Chicago Department of Buildings (online or in-person depending on project)
  • Coordinate inspections (we call for inspection, meet inspector, handle any corrections)
  • Ensure code compliance (ventilation rates, grease ducts, fire separation, refrigerant handling)
