When It Breaks at the Worst Time.

Based in Spiro, OK — minutes from Fort Smith and Poteau. We're still here next year, and the year after that.
What Counts as an Emergency Call
Not every HVAC issue is a true emergency — but these absolutely are. If any of these are happening at your house or business, call (918) 839-3734 right now.
No AC, Heat Advisory
Indoor temps climbing past 85°F with kids, elderly, pregnant, or pet residents — this is a true health emergency.
Top priorityNo Heat, Freeze Warning
Furnace down with temps below 32°F. Frozen pipes start within hours. We dispatch immediately.
Top priorityBurning Smell or Smoke
Electrical burning smell, smoke, or sparks from your HVAC. Turn off the breaker immediately and call.
EmergencyWater Leak or Flooding
Water dripping from indoor unit, flooded attic, ceiling stains spreading. Damages mount fast.
EmergencyFrozen Coil / Iced Up
Ice on indoor unit or copper refrigerant lines. Don't keep running — you'll destroy the compressor.
Same-dayTripped Breaker Repeatedly
HVAC breaker keeps tripping. Likely a short, failing capacitor, or compressor issue. Don't keep resetting it.
Same-dayWalk-In Cooler Down
Restaurant or store refrigeration failing. Every hour costs inventory. Commercial emergencies prioritized.
Commercial prioritySystem Won't Turn On
Dead thermostat, no power, no response. Could be a $25 part or a major failure — we diagnose fast.
Same-dayWhat Happens When You Call at 11PM.
You're sweating in the dark with no AC. You google "emergency HVAC near me" and call the first place that pops up. Half the time it goes to voicemail. The other half it's a national call center that takes your info and "passes it along to a local technician" — who may or may not actually call you back. That's not how we operate.
During business hours (Monday-Friday 7:30am-4:30pm), a real local dispatcher answers the phone at our Spiro, OK office. After hours, weekends, and holidays, the line routes directly to the on-call technician's cell phone. Someone real picks up. They take your name, address, and a quick description of what's happening, then give you an honest arrival window.
What we won't do: Pretend we can be there in 20 minutes when we're actually 90 minutes out. Quote you a fake "emergency rate" to scare you into committing. Show up at 2am to "diagnose" a problem we can't fix until parts open Monday. We're honest about response times and honest about pricing — and most of the time, that's why you called us instead of the big chain.
What to Do Before the Tech Arrives
You called. We're on the way. Here's what to do in the meantime so you're not making things worse — or putting anyone at risk.
Turn the System OFF
If your AC is running but not cooling, or your furnace is making weird noises — turn it off. Running broken equipment turns a $200 repair into a $1,500 compressor replacement.
Burning Smell? Flip the Breaker
Electrical burning smell or smoke = shut off the HVAC breaker at your electrical panel immediately. For gas furnaces, also turn off the gas valve. Then call.
Open Windows & Run Fans
If no AC and it's safe outside, open windows on opposite sides of the house. Run box fans or ceiling fans on high. Get airflow moving.
Hydrate & Check Vulnerable People
Drink water. Move kids, elderly, pregnant family members, and pets to the coolest part of the house. Heat illness is real — don't tough it out.
Take a Photo of the Issue
Water on the floor? Frost on copper lines? Sparks or burn marks? Photograph it before cleaning up. Helps the tech diagnose faster.
Have System Info Ready
Brand, model, approximate age. Check the data plate on the outdoor unit if you can do it safely. Saves diagnostic time when we arrive.
Still not sure if this is an emergency? Call (918) 839-3734 — we'll tell you straight if you can wait until business hours or if you need someone out tonight.
After-Hours Rates — Explained Up Front.
Here's the truth that most HVAC companies won't tell you on the phone: after-hours emergency service costs more. It's industry standard everywhere, but we're upfront about exactly what you're paying for.
Regular business hours (Monday-Friday 7:30am-4:30pm): standard diagnostic fee + standard labor rate. No premiums, no surprises.
Nights, weekends, and holidays: the diagnostic service call fee stays the same — but labor runs at 1.5x time-and-a-half. That's how we cover the on-call tech's overtime fairly. We tell you the rate before we dispatch so you can make an informed call. If your issue can wait until 8am Monday, we'll tell you straight.
What we don't do: jack up parts pricing on emergency calls. Inflate diagnostic fees because "it's after hours." Pressure you to commit to a $5,000 repair at midnight when a $200 fix would get you through the night. We're not here to take advantage of a bad situation.
Most Common Emergency HVAC Failures
The same handful of failures cause the vast majority of emergency calls in the Fort Smith and Poteau area. Here's what they look like and what they usually cost to fix.
Failed Run Capacitor
Symptoms: AC won't start, humming outdoor unit, fan won't spin. Cause: Heat stress kills capacitors fast in River Valley summers. Fix: Usually quick — we stock them.
Burned Contactor
Symptoms: AC unit completely dead, no response to thermostat. Cause: Worn contactor points fuse together or burn open. Fix: Standard replacement, parts on the truck.
Frozen Evaporator Coil
Symptoms: Ice on indoor unit or copper lines, weak airflow, AC running but not cooling. Cause: Restricted airflow or low refrigerant. Fix: Thaw, diagnose, repair root cause.
Clogged Condensate Drain
Symptoms: Water leaking from indoor unit, system shut off by safety switch. Cause: Algae or slime in the drain line. Fix: Clear the line, treat with algaecide.
Furnace Won't Ignite
Symptoms: Furnace blower runs but no heat, or system won't start at all. Cause: Failed igniter, flame sensor, or limit switch. Fix: Parts replacement, common stock on truck.
Blower Motor Failure
Symptoms: No airflow at vents, system "running" but no air movement, loud noises from indoor unit. Cause: Worn bearings or failed capacitor. Fix: Motor replacement (may need ordering).

Why HVAC Emergencies Hit Harder in the River Valley
A no-AC night in San Diego is uncomfortable. A no-AC night in Fort Smith during a July heat advisory is a medical emergency for vulnerable people. The Arkansas River Valley's combination of extreme summer heat, oppressive humidity, and harsh winter cold snaps makes HVAC failures here more dangerous than in many other parts of the country.
Summer reality: Fort Smith routinely hits 95-105°F with 70-80% humidity for weeks at a time. Heat index can climb past 110°F. Indoor temps without AC can reach 90°F+ within hours of a system failure — dangerous for infants, elderly residents, anyone on certain medications, and pets. Heat stroke can develop in less than an hour at those temps.
Winter reality: The River Valley sees ice storms most years and Arkansas-Oklahoma cold fronts that drop temps into the teens or single digits. No-heat overnight means frozen pipes within hours, burst plumbing within a day, and serious health risk for elderly or sick residents. Improvised heating with space heaters or unvented fuel heaters causes house fires and CO poisoning every winter.
That's why we treat HVAC emergencies as actual emergencies. Not "we'll get to it eventually" but "we're dispatching now." Same-day during business hours, after-hours dispatch nights and weekends. Call (918) 839-3734 and we'll get someone moving.
