Same-Day & Weekend Service for Heating & Cooling Failures
When your heat stops working at 11 p.m. in January or your AC quits during a July heat advisory, you need a team that picks up and shows up. Zen Air Heating and Cooling is available for same-day, weekend, and after-hours emergency HVAC service throughout Westchester County. We handle both heating failures and cooling failures, and our ownership team brings over 12 years of mechanical engineering experience to every diagnostic call.

When to Call for Emergency HVAC Service
Some HVAC problems can wait for a scheduled appointment. These can’t:
- Complete loss of heat in freezing temperatures: not just uncomfortable, but a pipe-bursting risk. When indoor temperatures are falling and lows are near 20°F, this is a safety call.
- Complete loss of cooling during a heat advisory: especially urgent in homes with elderly residents or young children.
- Burning or electrical odors from vents or the unit: a potential sign of an overheating component or wiring issue that needs immediate evaluation.
- A carbon monoxide alarm triggering near heating equipment: evacuate first, then call. Don’t restart the system.
- Loud banging, grinding, or screeching from a running unit: mechanical components in failure don’t fix themselves. Running the system longer can cause more damage.
- Short-cycling: the system turns on and off repeatedly without holding the set temperature. This pattern can damage the compressor and warrants same-day attention.
- Ice on the outdoor heat pump or indoor coil: a visible sign of restricted airflow or refrigerant loss.
Heat pumps and mini-split systems have failure modes that differ from traditional furnaces and central AC units, including refrigerant leaks and communication faults between indoor and outdoor units. If you have one of these systems, you need a team that works on them regularly, not one that’s guessing.

Common Emergency HVAC Repairs We Handle
Most emergency calls we see fall into a recognizable set of failures. Knowing what we’re likely dealing with before we arrive means we come prepared.
No-Heat Calls
Winter heating failures in Westchester often trace to a failed ignitor, a tripped limit switch, or a faulty thermocouple on a gas furnace. On heat pump systems, the most common culprits are a refrigerant charge issue or a reversing valve failure that leaves the system stuck in one mode. Our team works on both.
No-Cool Calls
Summer cooling failures frequently involve a refrigerant leak, a frozen evaporator coil, a failed capacitor, or a communication fault between indoor and outdoor mini-split units. A system that’s running but not cooling is often masking one of these issues.
Full System Shutdown
When the system won’t respond at all (no fan, no display), the cause is often electrical: a tripped breaker, a blown capacitor, or a failed control board. These are diagnosable and often repairable on the same visit.
While You Wait: Steps That Help
Before we arrive, a few quick checks can rule out simple causes and prevent additional damage:
- Check the thermostat for a dead battery or an incorrect mode setting. Some “emergencies” start here.
- Check the circuit breaker for a tripped switch. If it resets and immediately trips again, leave it off.
- Check the air filter. A severely clogged filter can cause the system to overheat and shut down.
- Clear debris, leaves, or ice from around the outdoor unit.
- Don’t repeatedly restart a system that keeps shutting off. Forced restarts add stress to components that are already failing.
- If you smell gas, don’t restart the system. Leave the building and contact your gas utility before calling us.
