What Happens When You Call After Hours
When you call 918-200-9111 at midnight, the phone rings to an Airo on-call technician. Not an answering service in another state. Not a recording asking you to press 1 for emergencies. A tech who has parts on his truck and knows the Tulsa metro.
He'll ask you a few questions — what the system is doing, outdoor temp, how long it's been out — and give you an honest arrival window. If there's a simple fix you can check yourself before he arrives (breaker, thermostat, drain float switch), he'll tell you. Sometimes that saves you a service call. When it doesn't, he'll be there.
After-hours calls include a diagnostic fee. That fee is credited against the repair if we do the work. We don't mark up parts differently because it's 2 AM. The pricing structure stays flat. You'll get the repair cost before any work starts — no surprises mid-job.
If the repair needs a part we don't carry on the truck — a coil, a compressor, a specific control board — we'll tell you that on the call. Parts get ordered immediately. If you need a full replacement, we can quote that same night. See our AC repair page and furnace repair page for what most repairs actually cost.
The Calls We Get at 2 AM in Tulsa
No cool in a heat wave
This is the most common summer emergency call. July in Tulsa, outdoor temps holding at 99°F even at 11 PM. Upstairs bedroom is 91°F. Kids won't sleep. The cause is usually a failed capacitor — a $10 part that costs about $80–$150 to replace with labor — or a contactor that's pitted and not making contact. Both parts are on the truck. We've fixed this problem at 1 AM on a Tuesday in Owasso and had people back to sleep by 2:30 AM.
No heat below freezing
January in Tulsa — 18°F outside, dropping to 10°F by morning. Furnace won't fire. This is a health and safety call for elderly residents, families with infants, and anyone without backup heat. Failed igniters are the most common furnace emergency in Tulsa; they fail because silicon carbide degrades after 5–7 years of cycling, and Tulsa's cold snaps push furnaces hard. Igniters are on the truck. Flame sensors are on the truck. We get most furnace no-heat calls resolved in a single trip.
CO alarm or gas smell
Carbon monoxide alarms or gas odors near the furnace are the only HVAC situation where you should call 911 before you call us. Get out first. After the fire department clears the structure, call us. A cracked heat exchanger is the most common furnace-related CO source — and it's invisible to the eye but detectable with proper equipment. We check for heat exchanger cracks on every furnace call and red-tag any system with confirmed CO risk. We won't let it slide because it's inconvenient or expensive.
Water from the air handler
Tulsa summers pull 1–3 gallons of water per hour out of the air on a humid August day. If the condensate drain line backs up, that water overflows the pan and can drip through ceilings. Many air handlers have a float switch that kills the system when the pan fills — which is why your AC might suddenly stop with no apparent cause. Clear the drain (a wet-dry vac at the exterior drain outlet usually does it), and the system restarts. We'll show you how to do this yourself and check whether the underlying cause was a cracked drain pan, improper pitch, or biological growth in the drain line.
First freeze of fall — and the heat pump won't switch modes
First October cold snap of the year. Temperatures hit the 30s overnight. The heat pump is stuck in cooling mode or the reversing valve won't shift. This is a common call for Tulsa homeowners with heat pumps who haven't tested the heating mode since last winter. A stuck reversing valve usually means the valve solenoid has failed. On dual-fuel systems, the gas furnace backup should kick in — if it doesn't, the furnace side needs diagnosis. Either way, this is a same-night fix if the right part is in stock.
What to Do When Your AC Quits at Night
Before you call, run through these steps. They take 5 minutes and occasionally solve the problem without a service call.
Check the breaker
Find the double-pole 30–60 amp breaker labeled "AC" or "Compressor" in your electrical panel. A tripped breaker sits in the middle position — not fully on or off. Reset it once. If it trips again immediately, don't reset it again. That means there's a short or overload — that needs a tech, not a reset.
Check the thermostat and filter
Make sure the thermostat is set to COOL and the temperature setpoint is below the room temperature. Then pull your air filter. If it's caked solid with dust — and Tulsa homes get there fast in spring — replace it and wait 30 minutes. A completely blocked filter can trigger a safety shutoff on the air handler.
Check the condensate drain pan
Look at the drain pan under your air handler. If it's full of water, the float switch has killed the system to prevent water damage. The drain line is clogged. Use a wet-dry vac at the exterior drain outlet and pull the clog. Once the pan empties, the system should restart. This is the DIY fix that works about 20% of the time on after-hours calls.
Note conditions and call us
Before you call, know: the outdoor temp, the indoor temp, whether the outdoor unit is running or silent, and how long the system has been out. That information helps us narrow the cause before we arrive. Call 918-200-9111. No hold music, no extension menu. The tech on call picks up.
Keep the house manageable until we arrive
Close blinds on south- and west-facing windows. If it's a two-story house, move to the lower floor — heat stacks upward. Run ceiling fans (they don't cool the air, but moving air feels 4–5°F cooler on skin). Keep interior doors closed to concentrate residual cool air in fewer rooms. For serious heat emergencies involving elderly family members or infants, move to a neighbor's or to a 24-hour business with AC while we're en route.
What's on the Truck at Midnight
We stock common failure parts on every truck so we can finish most emergency calls in a single trip. Here's what we carry for the most common after-hours repairs:
AC emergency parts
- Run capacitors — multiple microfarad ratings
- Start capacitors and start kits
- Contactors (single and double pole)
- Condenser and blower fan motors (common sizes)
- R-410A and R-454B refrigerant
- Drain pan tablets, drain line treatment
Furnace emergency parts
- Silicon carbide igniters (multiple types)
- Flame sensors
- Pressure switches (common ratings)
- Inducer motor capacitors
- Limit switches and rollout switches
- Gas valve solenoids (common brands)
Coils, compressors, circuit boards, and specific heat exchangers require parts sourcing. We'll tell you immediately if that's what the system needs — no pretending we can fix it tonight if we can't.
Why Tulsa HVAC Emergencies Happen When They Do
HVAC systems fail under load. Tulsa applies the most load in two windows: the first string of 100°F+ days in late June or early July, and the first arctic blast of January. Those are peak emergency call periods, and here's why.
Capacitors age with heat exposure. A capacitor that was fine in April starts to fail when the compressor runs hard for 8+ hours in 103°F heat. The system struggles through May and June without anyone noticing — until a Thursday in late June when it finally can't start the compressor at all. That's a 9 PM call to us on the same night half the metro's HVAC is working harder than it has in months.
Tulsa attics hit 140°F in July. Your air handler sits up there, along with your ductwork, your drain line, and often the electrical disconnect for the outdoor unit. Heat accelerates aging across every component — motor bearings, electrical insulation, drain line algae growth, refrigerant line connections. The system that ran fine all of last summer may have spent the winter slowly degrading.
Furnace emergencies cluster in January. Tulsa's coldest nights — when the furnace runs all day and into the night — are when igniters fail. A furnace cycling on and off for 18 hours straight stresses the igniter differently than it handles a typical fall night. Cold also makes gas valves sticky and pressure switches sluggish. The first 15°F week of winter is when the phones start ringing at midnight.
A spring or fall tune-up catches most of these failure modes before they become 2 AM calls. See our HVAC maintenance page for what a proper tune-up actually covers. The $125 PSO rebate for a qualifying tune-up doesn't hurt either.

Emergency HVAC FAQ
How fast does Airo respond to emergency calls?
Business hours (Mon–Sat, 7 AM–8 PM): typically within 60 minutes in Tulsa and close suburbs. After hours: 60–90 minutes. First heat wave of summer and first hard freeze: may stretch to 2–3 hours after hours when call volume spikes. We'll give you an honest window on the phone.
Is there an extra charge for after-hours calls?
After-hours emergency calls include a diagnostic fee — the same diagnostic fee structure as business hours. It's credited against the repair if you proceed with us. Parts pricing and labor rates stay consistent; we don't charge a premium just because it's late.
What counts as a real HVAC emergency?
True emergencies: no cooling when outdoor temperatures are above 90°F (health risk, especially for elderly or young children); no heat when overnight lows are below 35°F; carbon monoxide alarm or gas smell; active refrigerant leak causing damage. Slow cooling, unusual noise, or a system missing setpoint by a few degrees — those are 24–48 hour scheduled calls.
Do you actually pick up the phone after hours?
Yes. 918-200-9111 rings to an Airo on-call technician — no answering service, no hold queue, no voicemail. The tech who picks up can confirm parts availability and give you a real arrival window. If there's a basic fix you can try before he arrives, he'll walk you through it.
What parts do you have on the truck at night?
Capacitors, contactors, igniters, flame sensors, fan motors (common sizes), refrigerant, and condensate drain supplies. First-trip completion rate is high for the most common emergency calls. Coils, compressors, and specific circuit boards require parts sourcing — we'll tell you if that's what it needs before you schedule the call.
CO alarm went off near my furnace. Who do I call first?
Call 911 first. Get everyone out of the house before you call anyone. After the fire department clears the structure, call us. A cracked heat exchanger is the most common furnace-related CO source. We'll perform a full heat exchanger inspection and CO check before we clear the system for operation.
What if the fix needs parts you don't carry?
We'll tell you immediately — no stringing you along hoping something will work. Parts get ordered that night where possible, and we prioritize next-morning installation for heat/cool emergencies. If you're in a dangerous situation (extreme heat, hard freeze), we'll advise on safe interim steps until we can return.
Can I prevent most HVAC emergencies?
Yes. A spring AC tune-up in March–April and a fall furnace tune-up in September–October catch the most common failure modes — capacitors, igniters, drain line buildup — before they become 2 AM calls. See our HVAC maintenance page for what a real tune-up includes.
