The A/C Techs Air & Heat LLC provides 24/7 emergency HVAC service across the Dallas-Fort Worth metroplex. When your AC quits on a 105° day or your furnace dies during a hard freeze, a same-day appointment isn't a nice-to-have — it's a safety issue. We keep an on-call rotation year-round and prioritize true emergencies over routine service calls.

Quick answerCall 214.893.8749 anytime for a no-cool, no-heat, or suspected safety issue. Under normal demand, we reach most DFW addresses within 2–6 hours. During summer heat waves (June–September) and winter hard freezes, response stretches to 8–24 hours because every HVAC company is overwhelmed — but we still prioritize homes with vulnerable occupants, no heat under 55°F, or no cooling above 85°F.

What Counts as an HVAC Emergency?

A true HVAC emergency meets one or more of these thresholds:

  • No cooling with indoor temp above 85°F, especially with infants, elderly, or medically vulnerable occupants
  • No heating with indoor temp below 55°F, especially during a freeze warning or with frozen-pipe risk
  • Suspected gas leak (smell of rotten eggs near furnace or water heater)
  • Suspected carbon monoxide leak (soot, yellow flame, unexplained headaches or drowsiness with heater running)
  • Electrical issue — burning smell, sparks, repeatedly tripping breaker
  • Water leak from an attic air handler damaging drywall or ceilings
  • Frozen AC with visible ice on the refrigerant lines or outdoor unit

If you smell gas, leave the house first and call 911. For CO concerns, same thing. We'll handle the HVAC repair once the safety issue is cleared.

How Fast Can You Get Here?

Typical DFW emergency response times vary by season and demand:

  • Normal demand (October–May, non-peak) — 2 to 6 hours to most addresses
  • Summer peak (June–September) — 6 to 24 hours on high-demand days; often same-day for vulnerable households
  • Winter cold snap — 8 to 24 hours; prioritized for no-heat under 55°F
  • Overnight / weekend — on-call technician available; expect 2–6 hour response for true emergencies

We tell you straight up when we can arrive. If the wait is longer than you can accept, we'll help you find another reputable contractor — some problems just need solved now.

What Does an Emergency HVAC Call Cost?

Emergency service in the DFW market generally includes:

  • After-hours service call fee — typically $125–$250 (daytime weekday is $85–$150)
  • Parts and labor at standard rates — no inflated emergency markup
  • Written estimate before work begins — always

What to watch for: some contractors charge 2–3x normal rates during heat waves or cold snaps. We don't. Our emergency service fee covers the extra call-out; the repair itself is priced the same as any other day. If an estimate feels inflated, call a second company before you authorize work.

What Should I Do Before You Arrive?

While you wait for us:

  • Turn the system off at the thermostat if you suspect an electrical or refrigerant issue
  • Check the filter — a fully clogged filter causes about 15% of "emergency" calls and is a 2-minute fix
  • Check the breaker panel — if the breaker is tripped, flip it once to OFF then back ON. If it trips again, leave it off and wait for us.
  • For no-cool calls: run ceiling fans, close blinds on sun-facing windows, move vulnerable family members to the coolest room (usually the lowest floor, interior rooms)
  • For no-heat calls: open cabinet doors around water pipes, let faucets drip if temps are below freezing, gather warm layers and blankets in one room
  • If water is leaking from the air handler — shut the system off at the breaker and place a bucket or towels under the drip to protect drywall

Do You Service Commercial HVAC Emergencies?

We handle light commercial HVAC — small offices, retail, restaurants, and light industrial spaces with residential-style split systems or package units up to about 10 tons. For rooftop package units, walk-in coolers, or industrial chillers, we'll refer you to a specialist commercial contractor — it's faster than trying to stretch into work we're not the right fit for.

How Do I Avoid the Next HVAC Emergency?

Most HVAC emergencies we see were predictable. The big four preventable issues:

  • Skipped spring/fall tune-up — 70% of July no-cool calls trace back to a capacitor, drain line, or coil issue that a March tune-up would have caught
  • Dirty filter — causes frozen coils, high-limit shutdowns, and blower burnout
  • Aging 12+ year-old system with no maintenance plan — compressors and heat exchangers rarely fail without earlier warning signs
  • Clogged condensate drain — a $10 bleach flush prevents a $600 drywall repair plus an emergency call-out

Schedule a maintenance visit in the shoulder season (April or October) and most of this goes away.

FAQ

Frequently Asked Questions

Do you offer 24/7 emergency HVAC service in DFW?
Yes. We run a 24/7 on-call rotation year-round and dispatch emergency technicians across the Dallas-Fort Worth metroplex. Call 214.893.8749 anytime for no-cool, no-heat, or suspected safety issues. We prioritize households with vulnerable occupants, indoor temps above 85°F or below 55°F, and suspected gas or CO leaks.
What counts as an HVAC emergency?
A true emergency is no cooling with indoor temp above 85°F (especially with infants, elderly, or medically vulnerable occupants), no heat with indoor temp below 55°F, a suspected gas or carbon monoxide leak, a burning smell or electrical issue, water leaking from an attic air handler, or visible ice on an AC's outdoor unit. For gas or CO concerns, leave the house and call 911 first.
How quickly can you respond to an emergency call?
Under normal demand, we reach most DFW addresses within 2–6 hours. During summer heat waves (June–September) and winter cold snaps, response times stretch to 8–24 hours because every HVAC company is overwhelmed. We always tell you straight up when we can arrive — if the wait is too long, we'll help you find another reputable contractor.
How much does emergency HVAC service cost?
The after-hours service call fee is typically $125–$250 (normal daytime is $85–$150). Parts and labor are charged at standard rates — no inflated emergency markup. A written estimate is always provided before work begins. Watch out for contractors charging 2–3x during peak demand.
What should I do while waiting for an HVAC technician?
Turn the system off at the thermostat if you suspect an electrical or refrigerant issue. Check the filter (clogged filters cause about 15% of emergency calls). Check the breaker once — if it trips again, leave it off. For no-cool: run ceiling fans, close sun-facing blinds, and move vulnerable family to interior rooms. For no-heat: open cabinet doors around pipes and gather blankets in one room.
Is a furnace making a burning smell an emergency?
A faint burning smell during the first furnace run of the season is normal — it's dust burning off the heat exchanger and usually clears in 30–60 minutes. Persistent burning smells, electrical smells, or smoke are genuine emergencies. Shut the furnace off at the thermostat and breaker and call for service.
What if my AC is frozen with ice on the copper lines?
Frozen AC coils indicate restricted airflow (dirty filter, closed returns, failing blower) or low refrigerant from a leak. Running the system while frozen can damage the compressor. Shut the AC off at the thermostat, set the fan to 'On' to help melt the ice (2–4 hours), and call us to diagnose the root cause. Don't turn the compressor back on until a tech inspects it.
Do you handle commercial HVAC emergencies?
We handle light commercial HVAC — small offices, retail, restaurants, and light industrial with residential-style split or package systems up to about 10 tons. For rooftop package units, walk-in coolers, or industrial chillers, we refer to specialist commercial contractors.
How can I prevent future HVAC emergencies?
Schedule spring and fall tune-ups (most July no-cool calls trace back to issues a March tune-up would catch), change filters every 1–3 months, flush the condensate drain every 2–3 months, keep 2+ feet of clearance around the outdoor unit, and consider replacing systems over 15 years old before they fail in August.
Will my home insurance cover emergency HVAC repair?
Usually not. Standard homeowner's insurance covers sudden damage events (like a tree falling on the unit or lightning strike) but not normal mechanical failure or wear. Home warranty policies may cover mechanical failure but come with deductibles, coverage caps, and often required-contractor restrictions. Read your policy before calling.
