Emergency HVAC Service in St. Louis, MO

We know why a malfunctioning HVAC system can be an emergency. West-Central Missouri has some of the country’s most intense cold and hot weather. When your heating and cooling system is compromised, your health can also be compromised.

Don’t take chances. For emergency repair service in St. Louis, call 314-329-1943.


Never hesitate when your HVAC system needs emergency service. Our affordable financing options can guarantee your safety and comfort today.

These are signs you need emergency HVAC repair service:

  • CO detector alarm goes off: You and your pets should leave the house and call for emergency service.
  • Frequent circuit breaker tripping: Never ignore frequent tripping. A loose connector, wiring short, or capacitor issue could be the cause.
  • Frozen AC coils: They “freeze up” for various reasons, but it’s usually a lack of airflow.
  • HVAC won’t start: If it clicks but won’t start, it may be a thermostat issue.
  • Pilot light color: Older gas HVAC systems may have a visible pilot light. If the flame is not blue, you need emergency HVAC service.
  • Refrigerant leak: AC refrigerant has a distinct odor; if you smell it from your vents or near the unit, you may have a refrigerant leak. You might hear a hissing noise from the air pressure as it leaves the unit.
  • Odors: Smoke, natural gas, or burning wiring smells are emergencies. A smell of mildew or a dead-animal odor is not a critical emergency, but your air quality may be extremely unhealthy, so don’t delay a service request.
  • Strange noises: Bangs, rattles, screeching, and humming are all signs of an issue. Shut down the system and call us.

You can avoid emergency AC repair in St. Louis with spring AC maintenance. Our air conditioning professionals will prepare your system for Missouri’s sweltering summer days. When you need air conditioning repair, we examine three factors to determine if you need repair or AC replacement:

  • Age: If your system’s more than 10 years old, it’s time to budget for a new unit.
  • Energy efficiency: With a new system, you can save on monthly cooling bills.
  • Repairs: If you’ve already had several repairs, it may be time to cut your losses and invest in a new AC system.

Classic Aire Care also specializes in fast, efficient commercial AC service with minimal disruption to your business.
