Emergency HVAC Repair: What to Do First

Quick answer: No heat in freezing weather and no AC in extreme heat (especially with kids, elderly, or pets home) are genuine HVAC emergencies — call immediately. Smell gas? Leave and call your gas utility. Smell burning or see smoke? Shut the system down and call now. For everything else on this page, work the safety checklist below, then call (877) 317-0473 — answered 24/7, nights, weekends, and holidays.

HVAC emergencies do not respect business hours. Furnaces die at 2 AM in January; ACs quit at 4 PM in August. This guide tells you what actually counts as an emergency, what to do in the first 10 minutes, and what emergency service costs — so you act fast and smart instead of fast and panicked.

What Counts as a Real HVAC Emergency

Call immediately (do not wait for morning):

• No heat when it is freezing outside. Pipes can freeze and burst within hours; this is property-damage territory, not just discomfort.
• No cooling in extreme heat (95°F+) with vulnerable people home — infants, elderly, anyone with health conditions. Heat illness escalates fast.
• Gas smell (rotten eggs). Leave the house first, call your gas utility from outside, then call us. Do not operate anything electrical.
• Burning smell or visible smoke from equipment. Shut the system off at the breaker and call now.
• Water pouring from the indoor unit. Active leaks damage ceilings, walls, and floors by the hour — shut the system off to stop the flow.

Urgent but can wait for same-day (not 3 AM) service:

• System running but not keeping up, and temperatures are moderate
• Strange noises with normal heating/cooling performance
• One zone not working in a multi-zone home
• Thermostat acting up but the house is comfortable

When in doubt, call. A 2-minute conversation with a live coordinator beats guessing — (877) 317-0473.

The First 10 Minutes: Safety Checklist

1. Smell gas? Leave. Call the gas utility from outside. Nothing else on this list matters until that is resolved.
2. See smoke or smell burning? Shut the system off at the breaker (not just the thermostat). Do not restart it.
3. Water leaking? Shut the system off at the thermostat to stop condensate production. Place towels/buckets. If water is near electrical components, shut the breaker too.
4. No heat, no gas smell? Check the thermostat (HEAT mode, setpoint up), check the breaker, check the furnace power switch. Reset the breaker once.
5. No cooling? Check thermostat (COOL, fan AUTO), check both breakers (indoor + outdoor units), check the filter. Look at the outdoor unit — is it running?
6. Note what you observe. Write down: smells, sounds, error codes on the thermostat or furnace sight glass, when it started. This saves diagnostic time.

What NOT to Do in an Emergency

• Do not repeatedly reset a tripped breaker. One reset is diagnostic; repeated resets on a fault can cause electrical damage or fire.
• Do not repeatedly reset a gas furnace that will not stay lit. See our furnace troubleshooting guide — one reset, then call.
• Do not open the furnace or air handler cabinet unless you know exactly what you are looking at. High voltage and gas inside.
• Do not use the oven or grill for heat. Carbon monoxide kills quietly. Space heaters are safer — keep them 3+ feet from anything flammable and never unattended.
• Do not pour water on electrical components to "cool them down."

Keeping the House Safe While You Wait

No heat in winter:

• Open cabinet doors under sinks on exterior walls; let faucets drip slightly to prevent pipe freeze
• Close off unused rooms and hang blankets over doorways to concentrate heat
• Use space heaters safely (see above) — one per room, never daisy-chained on extension cords
• If the house will drop below freezing and the wait is long, shut off the main water and drain pipes

No cooling in extreme heat:

• Close blinds and curtains, especially on south/west windows
• Avoid ovens, dryers, and dishwashers — they add heat
• Cool showers, damp towels, and hydration for people; move pets to the coolest room
• If indoor temps exceed 95°F with vulnerable people home, consider relocating until the tech arrives — tell the coordinator

What Emergency HVAC Service Costs

Emergency service typically adds roughly 50% to standard pricing at peak times (nights, weekends, holidays) — the premium covers after-hours dispatch and overtime labor. On a $300 daytime repair, expect roughly $450 after hours. Diagnostics run the same $75–$150.

Is it worth it? When pipes are at risk of freezing or heat illness is a factor — unquestionably. For non-urgent issues, scheduling a next-day daytime visit saves the premium. A good coordinator will tell you honestly which situation you are in — that is what the call is for.

What the Tech Does on an Emergency Call

1. Stabilize first. Restore heating or cooling by the fastest safe means — sometimes a temporary fix to get you through the night.
2. Diagnose fully. Readings, not guesses — electrical tests, refrigerant pressures, combustion checks.
3. Written scope. The repair, the parts, the price — approved by you before work begins, even at 2 AM.
4. Complete the repair or schedule the follow-up if a special-order part is needed (with temporary measures in place).

Most emergency calls resolve in a single visit — service trucks carry the parts that fail most (capacitors, contactors, igniters, flame sensors, fuses).

Preventing the Next Emergency

Emergencies are overwhelmingly preventable:

• Twice-yearly tune-ups ($80–$200/visit): spring AC, fall furnace. This catches most failures before they happen.
• Replace aging systems proactively. A 16-year-old furnace will fail in January; a 14-year-old AC will fail in August. Plan the replacement on your schedule, not the weather's.
• Know your system's age and condition. If you do not know how old your equipment is, check the data plate — the serial number encodes the manufacture date.
• Keep our number saved: (877) 317-0473. The fastest emergency call is the one you do not have to look up.
