When a restaurant's AC fails in August, you lose a day's revenue every hour the dining room sits at 88°. When a medical office loses cooling, patient appointments cancel. When a retail store loses cooling, customers walk out. We service light commercial AC for small businesses across Mabank, Cedar Creek Lake Area, and the full DFW metroplex — restaurants, retail spaces, offices, salons, small medical offices, and multi-tenant properties. Same prioritized response as our residential emergency service, with after-hours scheduling that doesn't shut down your operation. COI (Certificate of Insurance) and W-9 available on request; billing to property owners or management companies with signed authorization.
Commercial AC Pricing — Honest Ranges
Commercial AC pricing varies dramatically by unit size, roof access, and complexity. Typical Mabank / DFW ranges:
- Standard commercial diagnostic: $129-$189 (higher than residential due to rooftop access, safety equipment, longer diagnostic time)
- Capacitor replacement (rooftop package unit): $380-$720
- Contactor replacement: $340-$580
- Refrigerant recharge (R-410A): $90-$350/lb + $180-$320 labor. R-22: significantly higher
- Rooftop unit compressor replacement: $2,800-$6,400 depending on tonnage and refrigerant type
- Rooftop condenser fan motor: $580-$1,200
- Rooftop blower motor / belt replacement: $420-$980
- Full RTU replacement (3-10 ton): $8,000-$28,000 installed — see our commercial HVAC installation page
- Emergency after-hours dispatch: +$50 diagnostic premium (vs residential $50), same flat-rate on parts and labor
Commercial AC Equipment We Service
- Rooftop package units (RTUs): 3-ton through 25-ton (Carrier, Trane, Lennox, York, Rheem, Daikin, AAON)
- Split system commercial units — when rooftop isn't an option or building code requires split configuration
- Mini-split / VRF systems for offices, retail, and multi-zone medical spaces (Mitsubishi, Daikin, LG, Samsung)
- Make-up air units — restaurant kitchens, manufacturing, print shops
- Exhaust fans and rooftop ventilation (Loren Cook, Greenheck, PennBarry, and other brands)
- Walk-in cooler and freezer HVAC integration (limited scope, we refer to specialized refrigeration for compressor work)
- Rooftop DOAS units (Dedicated Outdoor Air Systems) for modern efficient commercial buildings
Why Commercial HVAC Is Different Than Residential
Commercial systems fail differently than residential AC. Our commercial techs are trained for these specific patterns:
- Duty cycle 5-10x higher — commercial AC runs 12-16 hours a day in summer, vs residential 4-8 hours. Wear compounds fast.
- Rooftop exposure — commercial units face full-sun temperature extremes, UV degradation of insulation, wind damage, and roof heat that can exceed 150°F in summer
- Failure patterns skew toward compressors and contactors — residential fails at capacitors first; commercial fails at contactor pitting and compressor thermal overload
- Refrigerant charges are 3-10x larger — a leak that would take weeks to matter on residential can drain a commercial system in days
- Belt-drive blowers vs residential direct-drive — require belt inspection, tension adjustment, alignment as PM items
- Higher electrical loads — 208/230V 3-phase common on commercial vs 240V single-phase residential
- Rooftop safety requirements — OSHA fall protection, permit-required confined space in some equipment closets, ladder-lift for larger components
Our commercial techs carry the right refrigerant gauges (higher pressures on 410A rooftop systems), ladders, fall protection equipment, thermographic cameras for diagnosing electrical issues without shutdown, and parts inventory for common RTU brands.
After-Hours & Off-Hours Commercial Scheduling
We routinely schedule commercial work for times that don't disrupt your customers or staff:
- Restaurant maintenance: we schedule for 5-8 AM or after close, avoiding your lunch and dinner rushes
- Retail maintenance: pre-open or after-close scheduling; weekend early-morning options
- Medical / dental offices: patient appointment schedules honored; we work around your busy days
- Office buildings: weekend or after-6PM scheduling to avoid tenant disruption
- Emergency response: during operating hours if the failure is causing revenue loss (restaurant 88°F dining room, retail closed to walk-ins, medical office rescheduling patients)
Documentation for Insurance, Property Management, and Health Departments
Commercial customers often need documentation that residential customers don't. We provide:
- Certificate of Insurance (COI) with your landlord or property management company named as additional insured — before work starts
- W-9 on request for billing to LLCs, property management companies, or ownership entities
- Written service reports for every visit — useful for insurance claims, landlord requirements, health department inspections
- Combustion analysis reports for commercial gas heating (see commercial heating repair)
- Compliance documentation for refrigerant handling per EPA Section 608 (required for commercial refrigerant work over 5 lbs)
- Photos of failed components for warranty claims or ownership disputes
Same-Day Commercial AC Repair — Mabank, Cedar Creek Lake & DFW
Searching "commercial ac repair near me"? We dispatch same-day for most commercial ac repair calls across our entire service area — Mabank, Gun Barrel City, Seven Points, Kemp, Tool, Athens, Kaufman, and the full Dallas–Fort Worth metroplex including Plano, Frisco, Allen, McKinney, Arlington, Mesquite, Garland, and Rockwall. A real human answers the line 24/7 — usually Eric, Brad, or a senior tech, never a call center. Whether you searched for "commercial ac repair", "commercial air conditioning repair", "HVAC contractor near me", or "best HVAC company [your city] TX", we cover it — veteran-owned, locally operated, never acquired by private equity.
Brand-Name HVAC Equipment We Service
We service every major HVAC brand on the market across our Mabank and DFW service area: Trane, Carrier, Lennox, Goodman, Rheem, Amana, York, Bryant, American Standard, Heil, Daikin, Mitsubishi. Whether your existing equipment is 5 years old or 20, whether it's a high-end inverter system or a builder-grade base model, we approach the work the same way — honest diagnostic, flat-rate written quote, repair or install done right the first time.
Don't see your equipment brand listed? Call anyway. The HVAC industry only has a handful of core compressor and heat-exchanger manufacturers behind the dozens of consumer-facing labels — if it's a residential or light-commercial system, we likely service it.
Frequently Asked Questions
How fast can you respond to a commercial AC emergency?
Same-day for most calls in our Mabank / Cedar Creek Lake service area, same-day or next-morning in DFW metro. Restaurants and retail with active revenue loss get prioritized during business hours — we route the closest tech, not next-in-queue. During heat wave weeks response times extend 1-2 hours, but we don't turn away commercial emergencies.
Do you work after-hours so we don't have to close?
Yes — we routinely schedule commercial work for early morning (5-8 AM), late evening (after close), and weekends. Just tell us when you're closed or when your slow hours are and we'll schedule around it. After-hours scheduling on maintenance work incurs a modest $50 premium (same as residential); scheduled off-hours work at your convenience does NOT incur a premium.
Can you bill the property owner or landlord directly?
Yes, with signed authorization from either the tenant or the property owner. We're set up to invoice property management companies (Insite, JLL, CBRE, local property managers) and can provide W-9s, COIs, and any documentation your accounting needs. Some property managers prefer we bill the tenant with a landlord-approved cap on repair authorization — we do that too.
What commercial AC brands do you service?
All major commercial brands: Carrier, Trane, Lennox, York/JCI, Rheem, Daikin, AAON, Bard, and others. Also mini-split / VRF: Mitsubishi, Daikin, LG, Samsung. We stock common parts for RTUs in the 3-10 ton range on our trucks; specialty parts for larger commercial equipment usually next-day availability from local distributors.
Do you provide COI (Certificate of Insurance)?
Yes. We can email a COI naming your landlord, property management company, or building owner as additional insured within one business day of request. General liability coverage is $1M/$2M standard; higher limits available for specific project requirements. Workers comp coverage documentation included on the same COI.
How much does commercial AC repair cost?
Depends on unit size and failure type. Standard commercial diagnostic $129-$189 (higher than residential due to rooftop access). Common repairs: capacitor $380-$720, contactor $340-$580, blower motor $420-$980, condenser fan motor $580-$1,200. Rooftop unit compressor replacement runs $2,800-$6,400 depending on tonnage. Full RTU replacement $8,000-$28,000. All quoted flat-rate in writing before work begins.
Do you service walk-in coolers and freezers?
Limited scope — we can diagnose and repair the HVAC-integration portion (thermostats, air handlers connected to walk-in systems) but refer to specialized commercial refrigeration for compressor and refrigeration-circuit work on the walk-in itself. Different EPA certifications and equipment are required for commercial refrigeration.
Do you offer commercial preventive maintenance contracts?
Yes — see our commercial preventive maintenance contracts page. Quarterly PM visits with documented reports, priority scheduling on emergencies, discount on repair work. Multi-property pricing available for portfolios.
