Thermostat Error Codes

Thermostat error codes are your thermostat’s way of telling you what’s wrong and what you need to do to fix it. While an old, analog thermostat can’t give you an error code, any modern digital thermostat or wi-fi controlled thermostat will.

Two of the major brands of digital thermostats, Nest and Honeywell, offer services to help consumers understand what their thermostat error codes mean.

Whatever error you see, and whether or not we installed your thermostat, a One Hour Heating & Air Conditioning Technician can fix it. That’s a guarantee.

What’s the Point of Thermostat Error Codes

Picture a boiling hot summer day. You turn down the thermostat, but instead of providing cool air — your thermostat flashes you an error message. The thermostat error code, a combination of letters and numbers, might as well be ancient Greek to you.

More advanced thermostats allow you to save money and have maximum control over your home temperature. However, as thermostats become more complex and multifaceted, more can go wrong with them.

In theory, a thermostat error code tells you what’s wrong — and what needs to be done to fix it.

What Is My Thermostat Error Code Telling Me?

The type of thermostat error codes and what they mean vary by brand.

Two of the most common brands of advanced thermostats, Nest and Honeywell, provide complete explanations of their thermostats’ error codes.

In theory, you can fix your own thermostat. However, it may require advanced skills in wiring and in-depth knowledge about your AC system.

Interpreting thermostat error codes on your own is all well and good — that’s why thermostat manufacturers provide them to consumers. However, if you don’t want to sift through online databases or don’t want to try to attempt amateur electrical work, our experts can help.

Regardless of the make and model of your thermostat — or AC system — the HVAC experts at One Hour Heating & Air Conditioning likely can repair it. We respond to any HVAC or thermostat emergency around the clock. When you need a professional to help you understand a thermostat error code and rectify the issue, count on One Hour Heating & Air Conditioning.
