Commercial HVAC Emergencies in Las Vegas: A Different Category of Urgency
Short answer: Commercial HVAC emergencies in Las Vegas carry consequences that go beyond discomfort — employee safety mandates (OSHA requires reasonable working temperatures), inventory damage (food service, pharmaceuticals, electronics), customer loss, and potential lease violations. Response times from qualified commercial HVAC contractors range from 1-2 hours (off-season) to 2-6 hours (peak summer), with emergency diagnostic fees of $150-$400 and after-hours labor premiums of 1.5x-2x standard rates. Temporary cooling solutions (portable AC, spot coolers) can bridge the gap during major repairs. The single best investment is a preventive maintenance contract that catches failures before they happen — maintenance agreements reduce emergency calls by 70-80%.
Commercial HVAC emergency? Call (702) 567-0707 — The Cooling Company provides 24/7 commercial emergency service across the Las Vegas Valley.
At 2:15 PM on a Tuesday in July, the manager of a 12,000 square foot medical office in Summerlin realizes the waiting room is 84°F and climbing. Twenty-three patients are in various stages of their appointments. Two elderly patients are showing signs of heat distress. The server room housing electronic health records is at 87°F — the drives will begin failing at 95°F. The practice manager calls their HVAC contractor and gets voicemail. They call a second company — two-hour wait. They call a third — four hours, maybe.
This is a commercial HVAC emergency. It is different from a residential emergency in scale, urgency, and financial consequence. The medical practice will lose $8,000-$15,000 in revenue if they close for the afternoon. The restaurant three doors down will lose an entire dinner service — $5,000-$12,000 — plus food spoilage costs. The data center across the parking lot faces $50,000+ in equipment damage if temperatures exceed thresholds.
Commercial HVAC emergencies in Las Vegas are a when, not an if. Every business operating in the desert needs a plan for the day their system fails during the hottest week of the year. This guide covers what to expect, how to respond, and how to build resilience so that an equipment failure does not become a business crisis.
Response Time Reality: What Commercial Businesses Should Expect
Response time for commercial HVAC emergencies depends on three factors: the time of year, the time of day, and whether you have a maintenance contract with priority service.
| Scenario | With Maintenance Contract | Without Contract |
|---|---|---|
| Off-season (Oct-April), business hours | 1-2 hours | 2-4 hours |
| Off-season, after hours / weekend | 2-3 hours | 3-6 hours |
| Early summer (May-June), business hours | 1-3 hours | 3-6 hours |
| Peak summer (July-Sept), business hours | 2-4 hours | 4-8+ hours |
| Peak summer, after hours / weekend | 3-5 hours | 6-12+ hours (possibly next day) |
| Heat wave (3+ days above 115°F) | 3-6 hours | 8-24+ hours |
The difference between "with contract" and "without contract" is not just faster response — it is guaranteed response. During a July heat wave, every commercial HVAC company in the Las Vegas Valley is operating at maximum capacity. Contract customers are prioritized because those relationships represent ongoing revenue. Non-contract emergency calls fill remaining capacity, which during extreme heat may be zero available capacity until the following morning.
What determines how fast a technician arrives
- Contract status: Priority service agreements guarantee response within a specified window — typically 2-4 hours. This is contractual, not aspirational.
- Time of day: Most commercial HVAC companies run full crews from 7 AM to 5 PM. After-hours calls are handled by on-call technicians — fewer people covering the same geography.
- Severity and safety: A complete system failure in a medical facility or food service operation may be escalated over a partial cooling loss in an office. When calling, clearly communicate the business impact — occupant safety, inventory risk, regulatory implications.
- Equipment type: If the failed system is a standard rooftop unit, most commercial trucks carry common parts (contactors, capacitors, fan motors). If it is a specialized system (VRF, chiller, large air handler), the technician may need to return with specific parts, adding time.
The Emergency Service Call: Step by Step
Understanding the process helps facility managers set realistic expectations and prepare for the technician's arrival.
Step 1: The phone call (5-10 minutes)
When you call a commercial HVAC company for an emergency, be prepared with:
- Building address and unit/suite number
- Your role (building owner, facility manager, tenant) — this affects authorization for repairs
- Equipment description: rooftop unit, split system, package unit, VRF, chiller — and the unit's location (roof, mechanical room, exterior pad)
- Brand, model, and age if available — check the data plate or your maintenance records
- Symptoms: no cooling at all, reduced cooling, strange noises, water leaking, burning smell, tripped breaker, error codes on the control board
- Building occupancy status: how many people are in the building, any vulnerable populations (medical patients, elderly), any temperature-sensitive inventory
- Access information: roof access (key, ladder, hatch), gate codes, alarm systems, who will meet the technician
A dispatcher who asks these questions is preparing the right technician with the right parts. A dispatcher who says "we'll send someone" without asking details is sending a technician blind, which often means a return trip for parts.
Step 2: Technician arrival and assessment (30-60 minutes)
Commercial HVAC diagnosis follows a systematic protocol similar to residential but with additional complexity:
- Controls and BAS check: If the building has a Building Automation System, the technician checks alarm logs, setpoints, and control sequences first. BAS data can pinpoint the failure in minutes rather than hours of manual diagnosis.
- Electrical verification: Voltage at the disconnect, breaker status, safety switches, and fusing. Commercial systems have more electrical complexity — 3-phase power, variable frequency drives, staged compressors.
- Mechanical inspection: Compressor operation, condenser fan(s), refrigerant pressures (suction and discharge), economizer operation, belt condition on belt-driven components.
- Airside inspection: Filter condition, coil condition, blower operation, damper positions, ductwork integrity at connections.
- Diagnosis and options presentation: The technician identifies the failure, explains what is needed, provides a written estimate, and presents options — including temporary measures if the full repair requires parts or extended time.
Step 3: Repair or temporary solution
Common commercial emergency repairs that can be completed same-visit:
| Repair | Typical Cost Range | Time |
|---|---|---|
| Contactor replacement | $250-$600 | 30-60 min |
| Capacitor replacement | $200-$500 | 20-45 min |
| Condenser fan motor | $500-$1,200 | 1-2 hours |
| Belt replacement | $150-$350 | 30-60 min |
| Control board replacement | $600-$1,800 | 1-3 hours |
| Refrigerant recharge + leak seal | $600-$2,500 | 1-4 hours |
| Economizer repair/override | $300-$800 | 30-90 min |
Repairs that typically require scheduling (parts procurement, crane access, extended labor):
| Repair | Typical Cost Range | Lead Time |
|---|---|---|
| Compressor replacement (RTU) | $3,000-$8,000 | 1-5 business days (parts) |
| Evaporator coil replacement | $2,500-$6,000 | 2-7 business days |
| Heat exchanger replacement | $2,000-$5,000 | 3-10 business days |
| Full rooftop unit replacement | $8,000-$35,000+ | 1-4 weeks (equipment + crane) |
After-hours labor premiums for commercial emergency service typically run 1.5x standard rates for evenings and weekends, and 2x for holidays. These premiums reflect the real cost of maintaining 24/7 dispatch, on-call technician availability, and stocked service vehicles.
Temporary Cooling Solutions: Keeping the Business Running
When the repair requires parts that will not arrive for 2-5 days, or when a full system replacement is needed, temporary cooling bridges the gap between failure and resolution. This is the critical difference in commercial emergency response — the business cannot simply wait.
Portable AC units (spot coolers)
Portable commercial AC units provide 1-5 tons of cooling per unit and can be deployed within hours. They require a power source (208/230V, 20-30 amp circuits) and an exhaust path for hot air (window, door, or flexible duct to the exterior).
- Best for: Offices, retail, small medical practices — spaces under 3,000 square feet
- Rental cost: $200-$800/day per unit depending on capacity
- Limitations: Noisy (65-75 dB), require exhaust routing, limited capacity for large spaces
Trailer-mounted temporary cooling
For larger commercial spaces (5,000+ square feet) or critical environments (server rooms, medical facilities, food service), trailer-mounted temporary cooling systems provide 5-25 tons of cooling capacity and can be connected to the building's existing ductwork through temporary flexible duct connections.
- Best for: Restaurants, large offices, medical facilities, warehouses with heat-sensitive inventory
- Rental cost: $500-$3,000/day depending on capacity and duration
- Setup time: 2-6 hours for connection and commissioning
- Power requirements: 3-phase power, often requiring a temporary generator for sites without adequate electrical capacity
Emergency cooling strategies without equipment
While waiting for a technician or temporary equipment:
- Close blinds on all sun-exposed windows — west and south exposures in the afternoon can add 30-50% to the cooling load through glass
- Turn off non-essential equipment that generates heat (printers, copiers, kitchen equipment not in active use)
- Open exterior doors on the shaded side of the building (north or east in the afternoon) only if outdoor temperature is below indoor temperature — in Las Vegas summer, this is rarely the case during business hours
- Run ceiling fans and portable fans to improve air movement and perceived comfort
- Reduce lighting to the minimum safe level — every kilowatt of lighting adds 3,412 BTU of heat to the space
- If the building has multiple HVAC units and only one has failed, adjust zones to redirect conditioned air from non-critical areas to the affected area
Business Continuity Planning for HVAC Failure
Every Las Vegas commercial operation should have a documented plan for HVAC failure. This is not paranoia — it is the same category of business continuity planning as data backup, fire evacuation, and power outage procedures. In a city where outdoor temperatures exceed 110°F for 40-60 days per year, HVAC failure is a foreseeable event.
Elements of an HVAC failure response plan
- Primary HVAC contractor contact: Company name, 24/7 phone number, account number, contract terms. Post this information where facility staff can find it at 2 AM on a Saturday.
- Backup contractor contact: A second qualified commercial HVAC company in case the primary cannot respond. Verify they can service your equipment type before you need them.
- Temporary cooling vendor: Know which rental companies stock portable and trailer-mounted cooling equipment. During July heat waves, temporary cooling inventory sells out across the valley within 24-48 hours. Pre-arrange availability if your operation is temperature-critical.
- Temperature thresholds and decision triggers:
- 80°F indoor: Begin emergency cooling protocol (fans, reduce heat sources, contact HVAC contractor)
- 85°F: Deploy portable cooling, notify building occupants of the situation
- 90°F: Evaluate relocation of heat-sensitive inventory and vulnerable occupants
- 95°F: Close the space to non-essential personnel. OSHA does not specify an exact maximum temperature, but recommends action above 80°F and considers conditions above 95°F as high-risk
- Communication plan: Who notifies employees, customers, tenants? Who makes the decision to close the business? Who authorizes emergency repair expenditures above the facility manager's approval limit?
- Insurance and documentation: Document the failure, timeline, temperatures, and business impact. Some commercial property policies cover business interruption losses from equipment failure — but only with proper documentation. Photograph everything.
Emergency Maintenance Contracts: The Cost of Preparedness vs. the Cost of Crisis
A commercial preventive maintenance contract is the single most effective tool for reducing emergency HVAC failures. Systems that receive quarterly professional maintenance experience 70-80% fewer emergency failures than systems maintained reactively.
What a commercial maintenance contract should include
- Quarterly inspections covering all mechanical, electrical, airside, and controls components
- Priority emergency response with guaranteed maximum response time (2-4 hours)
- Filter replacement on a schedule appropriate for the environment (monthly during Las Vegas cooling season)
- Coil cleaning at least annually (quarterly in dusty environments or post-construction)
- Refrigerant charge verification at each seasonal inspection
- Wear component replacement (belts, capacitors, contactors) before failure — these are the components that cause most emergency calls
- Documentation and reporting after each visit — what was found, what was done, what needs attention
- Discounted labor and parts rates for repairs beyond the maintenance scope
Cost comparison
For a typical Las Vegas commercial property with 2-4 rooftop units (10-30 tons total):
| Approach | Annual Cost | Emergency Risk |
|---|---|---|
| No maintenance (reactive only) | $0 maintenance + $3,000-$15,000 emergency repairs | High — 40-60% chance of emergency per unit per year |
| Preventive maintenance contract | $1,500-$5,000 maintenance + $500-$3,000 repairs | Low — 5-15% chance of emergency per unit per year |
| Full-service agreement (maintenance + repairs) | $3,000-$8,000 all-inclusive | Very low — contractor proactively replaces wear items |
The math is straightforward. A $4,000/year maintenance contract that prevents even one emergency call per year pays for itself. Factor in avoided business interruption ($2,000-$20,000 per event depending on the business), and the ROI is overwhelming.

When Emergency Repair Becomes Emergency Replacement
Sometimes the emergency repair conversation becomes a replacement conversation. The compressor on a 16-year-old rooftop unit fails, the repair costs $5,500, and the unit uses R-22 refrigerant that is no longer manufactured. Repairing that unit is putting $5,500 into equipment that will likely fail again within 12-24 months and requires refrigerant that costs $75-$150 per pound.
Replace rather than repair when:
- The unit is 15+ years old (12+ years in Las Vegas for rooftop units exposed to UV and extreme heat)
- The repair exceeds 40% of replacement cost
- The system uses R-22 refrigerant
- Two or more major repairs have occurred in the past 24 months
- Energy costs have been trending upward despite maintenance
- The unit's SEER/EER rating is significantly below current standards (indicating 30-50% higher energy consumption than a modern replacement)
Emergency replacement does not mean immediate replacement. A competent commercial HVAC contractor can provide a temporary solution (portable cooling, temporary repair) to keep the business running while the replacement unit is ordered, delivered, and installed. This process takes 1-4 weeks for standard commercial rooftop units. For custom or large-tonnage equipment, lead times can extend to 6-12 weeks.

Frequently Asked Questions
How fast can a commercial HVAC technician arrive for an emergency in Las Vegas?
With a maintenance contract that includes priority response, expect 1-4 hours depending on the season and time of day. Without a contract, expect 3-8+ hours during peak summer. During extreme heat waves (115°F+ for multiple days), all response times extend as every HVAC company in the valley operates at maximum capacity. Contract customers receive guaranteed priority — this is the primary reason to have a maintenance agreement even if your systems are relatively new.
How much does commercial HVAC emergency repair cost in Las Vegas?
Emergency diagnostic fees for commercial systems range from $150-$400. Common repairs (capacitors, contactors, fan motors, belts) cost $200-$1,200 during business hours and 1.5x-2x that for after-hours service. Major repairs (compressors, coils, control boards) range from $2,500-$8,000 and are typically scheduled rather than completed during the emergency call. Full unit replacement ranges from $8,000-$35,000+ depending on tonnage and system type. Maintenance contract customers typically receive 10-20% discounts on parts and labor for emergency repairs.
Can I rent temporary cooling while my commercial HVAC is being repaired?
Yes. Portable spot coolers (1-5 tons, $200-$800/day) work for offices and small retail. Trailer-mounted systems (5-25 tons, $500-$3,000/day) serve larger spaces and can connect to existing ductwork. During July and August, temporary cooling inventory in Las Vegas sells out quickly, so pre-arrange availability with a rental vendor if your operation is temperature-critical. Your HVAC contractor can often coordinate temporary cooling as part of the emergency response, getting you operational faster than sourcing it independently.
Is my landlord responsible for commercial HVAC emergencies?
This depends entirely on your lease. In a gross lease or full-service lease, the landlord is typically responsible for HVAC maintenance and repair. In a triple-net (NNN) lease, the tenant is responsible for all maintenance, repair, and often replacement. Modified gross leases split responsibilities — the lease should specify who handles emergency repairs and who pays. Review your lease now, before an emergency, and clarify authorization procedures with your landlord or property manager. In all cases, document the failure and response for potential lease-related claims.
Does OSHA have a maximum workplace temperature for Las Vegas businesses?
OSHA does not specify an exact maximum indoor temperature. However, under the General Duty Clause (Section 5(a)(1)), employers must provide a workplace free of recognized hazards, and excessive heat is a recognized hazard. OSHA's heat guidelines recommend protective actions beginning at 80°F, with increased risk at 90°F+ and high risk at 95°F+. In Nevada, NRS 618 and NAC 618 address workplace safety, and OSHA Nevada (which administers the state plan) can cite employers who fail to address heat hazards. If your workplace cannot maintain reasonable temperatures during a HVAC failure, you have an obligation to implement heat illness prevention measures or close the space.
