Expert Insights

Pro Tips: Mini-Split Repair in O'Fallon

Before calling a technician, these checks can save time and help you describe the problem accurately.

1

Verify Thermostat Settings

Confirm the thermostat is set to the correct mode (heat/cool), the target temperature is appropriate, and the battery is fresh.

2

Inspect Electrical Connections

Corroded or loose wiring causes intermittent failures and is a fire hazard. Always shut off power at the disconnect before any inspection.

3

Install a CO Detector

Place carbon monoxide detectors near HVAC equipment and sleeping areas. Gas furnaces with cracked heat exchangers are a primary residential CO risk.
