What Our Emergency & Commercial HVAC Service Includes
24/7 Emergency HVAC
A failed compressor at 2 a.m. in the Heights or a furnace that won’t ignite on a January night in Aldine doesn’t wait for business hours. Our emergency line connects you to a live person, not a recording, who dispatches a background-checked, uniformed technician with the parts and tools to diagnose and repair on the spot. Most Emergency & Commercial HVAC in Houston calls are resolved in a single visit because our trucks are stocked for the nine major brands we service.
Commercial HVAC
Commercial systems in Houston face unique demands: longer run times, higher loads, and the cost of downtime that can idle your entire operation. We service package units, split systems, and VAV setups for retail, office, and light industrial buildings from Pasadena to Channelview. Our technicians are trained as journeymen who understand that your business can’t wait for a return trip.
Rooftop Unit Service
Rooftop units are the workhorses of Houston commercial properties, baking in summer sun and taking a beating from Gulf Coast humidity and occasional hail. We perform leak checks, refrigerant recovery, belt and bearing replacement, and full compressor diagnostics on RTUs up to 25 tons. In Cloverleaf and South Houston, we’ve replaced corroded condenser coils and failed economizer controls that other companies missed entirely.
Chiller Service
Chillers for mid-rise buildings and medical facilities in Bellaire and West University Place require specialized knowledge of refrigerant cycles, water treatment, and controls integration. We handle chiller startups, oil analysis, tube cleaning, and leak detection on centrifugal and scroll systems. A chiller down in July isn’t an inconvenience; it’s a building emergency, and we treat it that way.
Annual Maintenance
Our $89 Seasonal Tune-Up catches the worn contactors, dirty coils, and refrigerant leaks that lead to 3 a.m. emergency calls. For commercial clients, we build custom maintenance schedules around your operating hours, not ours. Properties in Humble and Deer Park that stay on our annual plan average fewer breakdowns and longer equipment life.
HVAC Inspection
Whether you’re buying a building in Channelview, selling in Jacinto City, or fulfilling insurance requirements, our written inspection documents every component’s condition with photos and straight talk about repair versus replace. No scare tactics, no inflated estimates. Just the facts you need to make a decision.

Brands We Service for Emergency & Commercial HVAC
We’ve serviced hundreds of Carrier systems across Houston, from residential Infinity series heat pumps to commercial WeatherMaster rooftop units. Our trucks carry common Carrier OEM parts, including pressure switches, control boards, and TXV valves, because we’ve learned over four decades which components fail most often in Gulf Coast humidity.
Trane’s Climatuff compressors and Spine Fin coils hold up well, but when they do fail, the repair requires specific tooling and refrigerant handling. We’ve rebuilt Trane commercial chillers in the Texas Medical Center area and replaced countless XV20i variable-speed compressors in West University Place homes. Goodman and Lennox systems are equally familiar territory, whether it’s a Lennox Merit series furnace ignition failure or a Goodman package unit with a grounded compressor. Whether you have Carrier, Trane, Lennox, Goodman, or any other make, we can help. Our technicians are trained on all nine major brands, and if we don’t have the part, we know where to get it fast.
Signs You Need Emergency & Commercial HVAC Right Now
- No airflow from vents. This could mean a failed blower motor, seized compressor, or tripped high-limit switch. In Houston’s climate, a building without airflow heats up within an hour, risking heat exhaustion for occupants and equipment damage from overheating.
- Loud grinding or screeching from the unit. Metal-on-metal noise usually signals a failing motor bearing or loose blower wheel. Continuing to run the system will destroy the component and potentially spread metal debris through the ductwork.
- Ice buildup on refrigerant lines or coils. Frozen coils indicate low refrigerant, restricted airflow, or a failing metering device. Left unaddressed, the ice melts into water damage and the compressor can slug liquid refrigerant, causing catastrophic failure.
- Burning smell or electrical odor. This demands immediate shutdown. Overheated wiring, failing capacitors, or seized motors can ignite nearby dust or insulation. We’ve responded to these calls at 11 p.m. in Galena Park and 4 a.m. in Pasadena; the ones that waited never ended well.
- Commercial thermostat reading 10+ degrees off actual temperature. Sensor drift, failed economizer controls, or a stuck damper can waste thousands in energy while half your building sweats and half freezes. In a retail or medical setting, that’s lost revenue or compromised care.

How Much Does Emergency & Commercial HVAC Cost in Houston?
A typical emergency HVAC repair in Houston runs $150-$650 depending on the component failed, time of call, and system accessibility. Furnace repairs in winter average $150-$700, with heat exchanger replacements at the higher end. Commercial rooftop unit repairs range wider based on tonnage and refrigerant type, but most common failures fall within the same $150-$650 band for residential-scale equipment. Full AC installation, when repair is no longer economical, runs $3,500-$7,500 for standard residential systems in Houston’s market.
Several factors move the needle. After-hours and holiday calls carry standard emergency rates, never hidden surcharges. Parts availability matters; we stock common components for Carrier, Trane, Lennox, and Goodman, but specialty boards or obsolete refrigerant systems may require next-day sourcing. Accessibility affects labor time; a rooftop unit in Channelview with safe crane access costs less to service than one buried in a crawlspace in Aldine.
The best way to avoid overpaying is simple: maintain your system. Our $89 Seasonal Tune-Up catches the $150 repair before it becomes a $650 emergency. And if another company quotes a replacement, our Free Second Opinion on Any Written Estimate gives you straight talk about whether repair is still viable.
Every estimate we provide is free, detailed, and valid for 30 days. Call (833) 313-7291 for exact pricing on your specific system.
