Check Your Thermostat and Power

Thermostat Check

• Verify the thermostat has power by checking its display. If the screen is blank, replace the batteries or check for loose wiring.
• Set the thermostat to the desired temperature. Confirm the system responds by blowing air or cooling the space.
• Inspect the thermostat wires. Loose or disconnected wires can disrupt temperature control.
• If the thermostat is unresponsive or malfunctioning, consider replacing it with a new unit.

Power Check

• Locate the main circuit breaker or fuse box for your home.
• Check if the HVAC circuit breaker has tripped or the fuse has blown.
• If tripped, reset the circuit breaker by flipping it back to the “on” position. If blown, replace the fuse with one of the same amperage.
• If the circuit breaker continues to trip or the fuse blows again, contact an emergency HVAC technician.

By performing these simple checks, you can quickly diagnose common HVAC issues and potentially resolve them yourself. However, if the problem persists or requires complex repairs, seek professional assistance from a reputable emergency HVAC service provider.
