Is This You?

Your System Is Down. Here's What Happens Next.

Most HVAC emergencies have a single, fixable root cause — a failed igniter, bad zone valve, tripped safety, seized pump, or low refrigerant. An experienced technician can usually diagnose and fix the problem in a single visit. The key is getting someone there fast with the right parts.

  • Boiler or furnace running but not producing heat
  • System cycling on and off without reaching set temperature

  • Carbon monoxide detector triggered near heating equipment

FAQs

Common Questions

Don't see your question here? Call us — we're happy to talk through your situation before you commit to anything.

Call Us
What should I check before calling?
For no-heat: check thermostat settings (set to Heat, above room temp), your circuit breaker, and the emergency shutoff switch (red switch near the unit or at top of basement stairs). For a boiler, also check water pressure gauge — should read 12–25 PSI. For no-AC: check thermostat mode and replace your filter if it's been a while. If none of this fixes it, call us.
How fast can you get to me?
We prioritize emergency calls across our service area. Call us and we'll give you a real ETA based on current dispatch — not a scripted promise.
Do you charge extra for emergency service?
We charge a diagnostic/call fee for emergency visits, which we'll tell you upfront. It's applied toward the repair if you proceed. No hidden fees.
What if my system needs a part you don't have?
We'll tell you honestly, give you an accurate timeline for the part, and discuss temporary heating or cooling options if needed.
Should I repair or replace an old system?
If your system is over 15 years old and a repair would exceed 50% of replacement cost, replacement usually wins. We'll give you the honest number — not the one that's most profitable for us.

Who do I call for emergency no-heat repair in Fairfield County, CT?

Is 24/7 furnace repair available in New Canaan, CT?

Yes. Airmax takes emergency furnace and boiler calls in New Canaan at any hour on (866) 203-0469 and gives you an honest ETA when you call rather than an open-ended window.

What does an emergency diagnostic cost?

The diagnostic fee is $89-$150 depending on the call, and it is applied to the repair if you approve the work. The repair itself is quoted for your approval before any work starts.

What should I do while waiting for the technician?

If your heating equipment is running but a carbon monoxide alarm has sounded, leave the home and call 911 first. Otherwise: set the thermostat to the mode you need, check that the equipment switch and breaker are on, confirm oil or propane supply, and check for a clogged filter or a reset button on the burner.

What breaks most often on an emergency call?

A failed igniter or flame sensor, a tripped high-limit or pressure safety, a bad zone valve or circulator pump, a blown capacitor on the condenser, a frozen evaporator coil or low refrigerant. Most are single-visit repairs.

Do you repair the same day or push a replacement?

Airmax repairs the failure first. If equipment is beyond economical repair, you get both the repair option and a replacement estimate in writing so you can compare them.

Which towns in Westchester County are covered for emergencies?

New Rochelle, Rye, Rye Brook, Port Chester, Mamaroneck, Larchmont, Pelham, Scarsdale and Mount Vernon, NY.

Do you service boilers, furnaces, heat pumps and central AC?
