Identify your system symptoms below to determine whether your situation requires immediate emergency evacuation, urgent 24/7 same-day dispatch, or scheduled diagnostic service.
Gas Odor (Rotten Eggs) or Carbon Monoxide Alarm Sounding
Critical Emergency (Level 1)Evacuate immediately to fresh air. Do not toggle electrical switches. Call 911 and National Grid Emergency from outside.
Never attempt to restart heating equipment or search for gas leaks with open flame.
Complete Loss of Heat in Freezing Sub-32°F Weather
Urgent Same-Day (Level 2)Check thermostat batteries and ensure red emergency shutoff switch is ON. Submit priority ticket for 5-minute callback.
Never jumper low-water cutoff or flame safety limit switches to force burner ignition.
AC Frozen Solid / Evaporator Encased in Heavy Frost & Ice
Rapid Service Required (Level 2)Turn thermostat COOL mode to OFF, switch FAN to ON. This safely melts the ice before our technician arrives.
Never chip ice with knives or screwdrivers—puncturing aluminum/copper coil tubes destroys the system.
Air Handler Leaking Water Through Ceiling or Living Space
Immediate Overflow Hazard (Level 2)Turn system OFF to stop condensate production. Place bucket and towels beneath leak. Our tech will clear the trap.
Do not continue running AC while water overflows ceiling drywall.
AC Outdoor Condenser Hums Loudly But Fan / Compressor Stalled
Same-Day Electrical Repair (Level 3)Shut system off at thermostat. The dual-run capacitor has degraded and needs replacement before compressor burns out.
Do not let unit hum continuously—locked-rotor amps can burn out expensive compressor motor windings.
