How to Reset My Thermostat:

​If your heating or cooling system isn’t working right, one of the easiest fixes is to reset your thermostat. Whether your system isn’t turning on, your display is blank, or your home feels too hot or cold, resetting your thermostat can often get things back on track quickly.
At Newport Beach HVAC Services, we often get calls from homeowners who think their HVAC system is broken — but all it needed was a simple thermostat reset.

🔍 Why Resetting Your Thermostat Matters  Your thermostat acts as the brain of your HVAC system, controlling temperature settings and communicating with your furnace, air conditioner, or heat pump.
A reset can help when:

• Your system isn’t responding to thermostat changes
• Your HVAC runs constantly or shuts off too soon
• You recently had a power outage or changed batteries
• The display is frozen or blank
• You installed a new HVAC unit or thermostat

Resetting clears minor software glitches and restores the factory settings, often resolving communication issues between your thermostat and your HVAC system.

⚙️ How to Reset Your Thermostat (Step-by-Step)  The reset process depends on the thermostat type. Below are the most common types found in Newport Beach homes.

1. How to Reset a Programmable Thermostat                                                                        Step 1: Locate the reset button — usually a small, recessed button marked “Reset.”
Step 2: Use a paperclip or small pin to press and hold it for 5 seconds.
Step 3: Wait for the screen to flash or restart.
Step 4: Re-enter your temperature preferences and schedule.
If your thermostat doesn’t have a reset button:

• Remove it from the wall mount.
• Take out the batteries for 30 seconds.
• Reinsert the batteries and reattach the thermostat to the wall.

2. How to Reset a Smart Thermostat (Nest, Ecobee, Honeywell Home)Google Nest Thermostat:

1. Press the dial to open the menu.
2. Go to Settings → Reset → Restart or Factory Reset.
3. Choose Restart for a simple reboot or Factory Reset to wipe all settings.

Ecobee:

1. Tap Menu → Settings → Reset.
2. Choose “Reset All Settings” or “Reset Registration.”

Honeywell Home:

1. Press and hold Menu.
2. Use the arrow keys to find “Reset.”
3. Choose “Factory Reset” and confirm.

After a reset, reconnect your Wi-Fi and re-enter your preferred heating and cooling schedules.

3. How to Reset a Non-Programmable (Manual) Thermostat  If you have a basic digital or dial thermostat:

1. Turn your thermostat to Off.
2. Locate the circuit breaker connected to your HVAC system.
3. Turn the breaker Off for 30 seconds, then back On.
4. Turn your thermostat back to Cool or Heat mode and adjust your desired temperature.

This power cycle resets the thermostat and the connected HVAC unit.

⚡ Pro Tip: Reset After Power Outages or Battery Changes   If you live in coastal Newport Beach, power fluctuations or humidity can occasionally cause short-term electrical glitches.
After a power outage, it’s wise to reset your thermostat to ensure proper communication with your HVAC unit.
Likewise, when changing batteries, remove them for at least 30 seconds before installing new ones. This ensures a full system refresh.

🧰 What to Do If Resetting Doesn’t Work   If your thermostat is still unresponsive after resetting:

• Check that the breaker for your HVAC system isn’t tripped.
• Make sure your thermostat’s batteries are fresh.
• Verify your system’s wiring is properly connected.

If everything looks fine and your system still isn’t responding, the issue may be with the furnace control board, wiring, or HVAC unit itself.
That’s when it’s time to call in a licensed professional.
