COMMON PROBLEMS WE SOLVE
Recognizing these warning signs early can prevent costly breakdowns and protect your family’s comfort and safety.
Complete System Shutdown
Furnace, AC, or heat pump won't turn on at all — often an electrical fault, failed capacitor, or tripped safety switch.
No Heat in Winter
Furnace running but producing no warm air — could be a faulty heat exchanger, gas valve, or igniter.
No Cooling in Summer
AC blowing warm air — low refrigerant, compressor failure, or a dirty condenser coil are common culprits.
Carbon Monoxide Alarm
A CO detector trigger near HVAC equipment is a life-safety emergency. Evacuate and call us immediately.
Frozen Coils or Lines
Ice on your indoor unit or refrigerant lines signals restricted airflow or low charge — continued operation can destroy the compressor.
Unusual Smells or Sounds
Burning odours, metallic clanking, or high-pitched squealing indicate components that need immediate attention.
