Our Emergency HVAC Services

When HVAC emergencies strike, time is critical. Attempting DIY fixes or waiting too long to schedule professional service can lead to bigger problems, including costly system damage. Calling a professional like Koch & White ensures the issue is diagnosed accurately and repaired swiftly, restoring your comfort and safety.

Emergency AC Repair

A sudden air conditioning failure can leave your home uncomfortable, especially during Ann Arbor’s humid summers. Our team can handle a wide range of urgent AC problems, including:

  • Compressor and refrigerant issues: Leaking refrigerant or failing compressors can halt cooling altogether.
  • Thermostat failures: Malfunctioning thermostats cause erratic cooling cycles or complete shutdowns.
  • Fan motor and capacitor replacements: Critical for airflow; failure here can lead to overheating or no cooling.
  • And more

Emergency Heating Repair

Facing a heating emergency in the middle of a Michigan winter isn’t just inconvenient — it can be dangerous. Koch & White provides prompt repairs for:

  • Furnace breakdowns: Our team can resolve problems with gas or electric furnaces.
  • Heat pump failures: Reliable operation is critical, especially for homes that rely solely on heat pumps.
  • Pilot light and ignition system issues: If your furnace won’t ignite, it needs immediate attention.

Don’t delay repairs. Call Koch & White today to schedule emergency HVAC services, or book an appointment online for less urgent issues.
