How to fix your AC thermostat: Easy steps

Check the Power

For battery-powered thermostats, try replacing the batteries. If it’s a wired model, check that the circuit breaker hasn’t been tripped.

Clean the Thermostat

Dust and dirt can interfere with the internal sensor. Open the thermostat cover and clean it out using a soft cloth or a can of compressed air.

Recalibrate the Thermostat

Is your thermostat reading the wrong temperature? Recalibration may fix the issue, many models have a setting for this; if yours doesn’t, a professional may need to assist you.

Reset the Thermostat

A quick reset can often solve many thermostat glitches. Refer to your manual for the correct reset procedure.

Check the Wires

Loose or damaged wires can cause issues with the thermostat function. If you’re comfortable, check the connections yourself. If you notice any damaged wires, it’s best to call in a professional.

Upgrade to a Smart Thermostat

If your thermostat is old, it might be time to upgrade. Smart thermostats are more accurate, energy-efficient, and come with added features like remote control via smartphone.
