24/7 Emergency HVAC in Greenwich, CT
Around-the-clock emergency HVAC in Greenwich, CT for homes left without heat in a Connecticut winter, without cooling in a heat wave, or with a system that keeps shutting down.
HOW WE HANDLE IT
What Happens When You Call
When your heat or cooling quits at a bad hour, a clear plan helps. Here is how our licensed HVAC technicians handle an emergency call.
Step 1
Phone Triage
When you call, we ask what the system is doing: no heat, no cooling, a tripped breaker, water pooling near the air handler, or a strange noise or smell. Those details tell a licensed technician which parts and tools to bring, and whether anything calls for 911 first.
Step 2
Hands-On System Diagnosis
At your home, a licensed technician checks the thermostat, power, filter, ignition, and safety controls to find the actual fault, then explains what failed and what the fix involves before touching anything.
Step 3
Restoring Heat or Cooling
Once you approve the plan, we repair the fault, whether a failed capacitor, contactor, flame sensor, or blower motor, and run a full cycle to confirm it works. If a part must be ordered, we explain your interim options.
Step 4
After the Emergency
Before leaving, we point out what could cause a repeat breakdown, like a clogged filter, corroded condenser coil, or blocked condensate line, and suggest seasonal maintenance to stay ahead of it.

WHAT WE COVER
When to Call for Emergency HVAC Help
Some HVAC problems can wait for a weekday appointment. Others cannot: a furnace or boiler that quits in a January cold snap, or central air that dies during a humid Greenwich heat wave.
Typical calls include emergency heating repair for a furnace that won’t ignite or a boiler that goes cold during a nor’easter, plus AC breakdowns, ice on the refrigerant lines, water leaking from an air handler, and loud banging or grinding inside the unit.
Safety comes before any repair. If you smell gas or a carbon monoxide alarm sounds, get everyone out of the house, then call 911 or your gas utility from outside. Once it has been declared safe, call us and a licensed technician will take care of the HVAC repair.

WHY CALL RIGHT AWAY
Benefits of Calling Without Delay
A small fault left running can turn into a bigger failure. Getting a licensed technician involved early protects your comfort, your equipment, and your household’s safety.
Protects Your Equipment
Stopping a struggling compressor or short-cycling furnace early can keep one failed part from damaging the motor, coil, or heat exchanger.
Limits Water Damage
A backed-up condensate pan can soak a basement floor or stain the ceiling below an attic unit, so shutting the system down early keeps cleanup small.
Safety in Every Season
Burning smells, overheating motors, and a house that drops toward freezing or swelters in summer are safety issues, and we take those calls day or night.
No Heat or No Cooling? Call Now
Call any hour and we will help you work out the next step for your heating or cooling.
