Commercial HVAC services in Denver: scope of work

Nextech provides commercial HVAC service in Denver for a range of facility types. Typical service needs include diagnosing and repairing cooling, heating, ventilation, and controls-related issues; performing preventive maintenance to reduce unexpected breakdowns; and supporting commercial HVAC system design and installation when you’re planning an upgrade or replacement.

If you’re comparing providers, commercial HVAC often involves larger equipment and more complex systems (for example, rooftop units, multiple zones, and building controls) and usually requires planning to minimize business disruption.

When to request emergency service vs. schedule standard service

Use these decision triggers as general guidance:

• Breaker trips repeatedly, electrical smell, or visible sparking: Shut the unit off at the thermostat (and disconnect if you’re trained/authorized), keep the area clear, and request 24/7 emergency service.
• Unit short-cycles (rapid on/off) or won’t stay running: If it’s not maintaining temperature or it’s cycling every few minutes, request urgent service; continued cycling can stress compressors and motors.
• Complete loss of cooling/heat in occupied or process-critical areas: Request emergency service—especially if indoor conditions are trending unsafe for people, equipment, or product.
• Mild temperature drift or comfort complaints with the unit still operating: Schedule standard service soon (often within a few business days is reasonable general practice) and consider a preventive maintenance visit if you’re seeing recurring issues.

What we’ll ask for on the phone (and what to do/not do)

Having a few details ready can speed up troubleshooting and help route the call appropriately:

• Unit/RTU ID or location (roof tag, unit number, or serving area)
• Current thermostat/zone setpoints and actual space temperature
• Any alarms or fault codes (thermostat, controller, or BAS)
• What changed recently (filter change, construction dust, doors propped open, power event)
• Hours of operation and when the problem started (constant vs. intermittent)

Safety note: If you suspect an electrical issue (burning odor, tripped breakers that won’t hold, buzzing, or smoke), don’t keep resetting and running the equipment. Avoid opening electrical panels unless you’re qualified and authorized—shut the system down and request emergency service.
