Diagnostic
The trusted name for AC repair in Fort Smith & Poteau.
When your air conditioner goes out in the middle of an Arkansas heat wave, you don't want to wait three days for a corporate dispatcher to fit you in. You want a real technician on your driveway today. That's what Clark HVAC does.
Trucks Already on the Road
Our techs run service routes across Fort Smith, Poteau, Spiro, Van Buren, Sallisaw, and the surrounding towns every single day. Most AC repair calls in the River Valley get a same-day appointment — often within a couple hours.
A Real Family, Not a Franchise
Clark HVAC is family-owned and locally based in Spiro, OK. When you call, you talk to someone who lives down the road from you — not a script-reading dispatcher. We answer to our neighbors, not to corporate.
$90 Diagnostic. No Surprises.
Flat $90 to diagnose your AC problem. Flat $90/hour for labor. We give you an honest quote before we start any work — and we'll never try to sell you a $9,000 replacement when a $200 capacitor will fix it.
We Fix Them All
Trane, Carrier, Lennox, Goodman, Rheem, Ruud, American Standard, York, Bryant, Amana, Heil, Payne, Mitsubishi, Daikin, TCL — every major brand of central AC, heat pump, and mini-split. Old units, new units, mobile home units. We've worked on all of it.
If your AC is doing any of this, call us right now.
Most air conditioner problems get worse the longer you wait. A small refrigerant leak becomes a burnt-out compressor. A weak capacitor becomes a fried motor. Catch it today — pay a lot less tomorrow.
AC blowing warm air
Usually a low refrigerant charge, a dirty condenser, or a failed compressor — every one of those is fixable today.
AC won't turn on
Tripped breaker, bad thermostat, blown capacitor, or contactor failure. We diagnose and fix on the first visit.
Outside unit running, no cold air
Classic sign of a stuck contactor, a bad blower motor inside, or a refrigerant issue. We'll trace the real cause.
Frozen AC coil / ice on lines
Almost always low refrigerant or airflow restriction. Turn it off and call us — running it iced will kill the compressor.
Refrigerant leak
We carry R-410A, R-454B, and service older R-22 systems. Electronic leak detection and proper repair, not just a top-off.
Bad capacitor
The #1 cause of AC failure in Oklahoma and Arkansas heat. We stock capacitors for every common brand — usually under an hour to fix.
Fan motor failure
Outside fan not spinning? Inside blower silent? Both can melt down your system fast. Same-day motor replacement on most calls.
AC leaking water inside
Clogged condensate drain, cracked drain pan, or a frozen evaporator. We clear the line and find the root cause.
Loud or strange noises
Grinding, buzzing, screeching, or banging means something is failing — usually the motor, compressor, or fan bearings.
AC short cycling
Turning on and off every couple minutes? Could be the thermostat, low refrigerant, an oversized unit, or a clogged filter.
High humidity in the house
AC running but the house feels muggy? Your system isn't pulling moisture properly — fixable, and often a simple cause.
Sky-high power bill
A struggling AC pulls double the amps. We'll diagnose what's making it work overtime and get your efficiency back.
We're your neighbors. Not a national chain.

And our phone is answered by someone who actually knows your area — not a call center in another state.

In most cases, same-day — often within a couple hours of your call. We run trucks across Fort Smith, Poteau, Spiro, Van Buren, Sallisaw, and the surrounding towns every day, so we're usually nearby. Call (918) 839-3734 and we'll tell you exactly when a tech can be there.
How much does AC repair cost?
Our diagnostic is a flat $90 and our labor rate is $90/hour — no hidden trip fees. Most common AC repairs (capacitor, contactor, motor, refrigerant top-off) come in well under $500 total. We give you a written quote before any work starts, so there are no surprises.
Do you offer 24/7 emergency AC repair?

What AC brands do you service?
Every major brand — Trane, Carrier, Lennox, Goodman, Rheem, Ruud, American Standard, York, Bryant, Amana, Heil, Payne, Mitsubishi, Daikin, TCL, and more. Central AC, heat pumps, ductless mini-splits, package units, and mobile home systems. If it cools, we work on it.
Should I repair my old AC or replace it?
Honest answer: it depends on the unit. As a general rule, if your AC is under 10 years old and the repair is less than half the cost of a new system, fix it. If it's 12+ years old, on R-22 refrigerant, and needs a major part like a compressor or coil, replacement usually makes more financial sense. We'll give you both numbers and let you decide — no pressure either way.
Why is my AC blowing warm air?
The most common causes in this part of Arkansas and Oklahoma are: low refrigerant (often from a slow leak), a failed capacitor, a dirty or blocked condenser coil, a tripped breaker on the outdoor unit, or a thermostat set to "fan only" instead of "cool." Any of those can be diagnosed and fixed in a single visit.
Do you work on mobile home AC units?
Absolutely. We repair, replace, and maintain HVAC systems in mobile homes, manufactured homes, doublewides, and modular buildings throughout Fort Smith, Poteau, and across the entire service area. Same pricing, same fast response.

Do you offer financing on AC repairs and replacements?
Yes. We offer 0% financing options on qualifying new AC installs and many major repairs. Ask your tech about it when we're out — we'll walk you through it in plain English, no fine-print games.
Your AC won't fix itself. We will.
