Our team provides round‑the‑clock emergency response, upfront pricing, and fast dispatch across Greater Boston.
What Counts as an AC Emergency vs a Next‑Day Repair
When heat and humidity spike in Boston, AC issues escalate quickly. Not every problem needs a midnight visit, but some do. Use this guide to decide.
Clear 24/7 Emergencies
- Electrical burning smell, smoke, or a repeatedly tripping breaker.
- Reason: Possible shorted compressor, failed capacitor, or contactor. Electrical faults can worsen fast.
- Water leak that soaks ceilings or walls.
- Reason: Condensate overflow can cause ceiling collapse and mold.
- System runs but no cold air during a heat advisory, with elderly, infant, or health‑sensitive occupants.
- Reason: Heat stress risk. Comfort becomes a safety issue.
- Outdoor unit loud grinding or screaming noise.
- Reason: Failing compressor or fan motor can seize.
Likely Next‑Day Repairs
- Uneven cooling in a few rooms but the home is livable.
- Thermostat miscalibration without breaker trips.
- Mild noise changes without burning smell or metal‑on‑metal sounds.
"Noticed our A/C wasn't pumping out cold air... had a service representative show up within a few hours... Prices were reasonable, service was 10/10."
Quick Homeowner Triage Before You Call
Safe checks can speed the repair and sometimes restore cooling.
1) Thermostat and Power
- Set to Cool, Fan Auto, and 3 to 5 degrees below room temperature.
- Replace batteries if wireless.
- Check the AC breaker in the panel. If it trips again after a reset, stop and call.
2) Airflow and Filters
- Replace a clogged filter. A starved blower can freeze coils and flood pans.
- Open supply registers and return grilles. Clear furniture from returns.
3) Outdoor Unit
- Remove visible debris around the condenser. Maintain 18 inches of clearance.
- If you see ice on lines or coils, turn system Off and run Fan Only for 60 minutes. Then try Cool again. If ice returns, call.
4) Condensate and Water Leaks
- Check the indoor air handler pan. If water is near an overflow switch, power off and call to prevent ceiling damage.
"They considered our situation an emergency and came back the very next day... worked hard and were extremely professional."

Common Emergency AC Failures and Fast Fixes
Failed Start Components
- Symptoms: Humming outdoor unit, fan runs but compressor will not start, or frequent breaker trips.
- Likely cause: Weak capacitor or stuck contactor.
- Typical fix: Replace failed component, check wiring, confirm start‑up amperage.
Refrigerant Leaks
- Symptoms: Warm supply air, ice on lines, long run times.
- Likely cause: Leaks at flare fittings, service valves, or evaporator coil.
- Typical fix: Find and repair leak, evacuate, weigh in refrigerant to manufacturer spec, and verify superheat/subcooling.
Condensate Overflows
- Symptoms: Water near the air handler, ceiling stains in triple‑deckers or condo ceilings.
- Likely cause: Clogged drain or failed float switch.
- Typical fix: Clear line, add cleanout, verify float operation, and protect drywall.
Seized Fan Motor or Failing Compressor
- Symptoms: Screeching, grinding, or repeated lockouts.
- Typical fix: Replace failed motor, test capacitors, or quote compressor with warranty check.

Safety Tips You Should Never Ignore

Prevent the Next Emergency
