Installation: What you need to know

You’ll likely be able to install the thermostat yourself if you’re comfortable with basic wiring and using a screwdriver. ecobee ships the Power Extender Kit so you don’t have to hunt for a C wire in many homes.

The included instructions are clear, and the app provides step-by-step guidance during setup. However, if your HVAC system is less common or you’re not comfortable with wiring, you might prefer professional installation.

Installation steps (concise)

You’ll follow these general steps during install:

1. Turn off power to your HVAC at the breaker.
2. Remove your old thermostat and label wires.
3. Mount the ecobee backplate and connect wires (or install PEK at furnace if no C wire).
4. Attach the thermostat and restore power.
5. Complete setup in the ecobee app and run compatibility checks.

The PEK is installed at the furnace control board, which is straightforward for most homeowners but may be better handled by a technician if you’re unsure.

Compatibility and system support

You’ll want to check compatibility because the thermostat supports a wide range of HVAC setups but not every single system out there. ecobee claims compatibility with 90% of systems and provides a Compatibility Checker on their support page.

If your system is a conventional forced-air setup, heat pump, or boiler, you’re likely fine. Multi-stage systems and older or unique control schemes may need extra attention.

Systems supported

You’ll find support for:

• Gas, oil, and electric systems
• Forced air conventional systems (2H/2C)
• Heat pumps (3H/2C)
• Boilers and dual-fuel setups

If in doubt, use the compatibility checker or consult a pro. Installing on an unsupported system could cause errors or incomplete functionality.

Energy savings and efficiency

You’ll be interested in savings: ecobee states up to 26% annual savings on heating and cooling compared to a steady 72°F hold. The savings come from intelligent scheduling, occupancy-based adjustments, and remote control that avoids conditioning an empty home.

The thermostat learns your temperature preferences and adapts, which helps avoid wasteful heating or cooling. Energy reports in the app make it clear where savings occur and allow you to fine-tune behavior.

How savings are achieved

You’ll notice energy savings through:

• Auto-away adjustments when no one is present
• Learning schedules to reduce runtime
• Integration with SmartSensors to condition only occupied rooms
• Humidity-aware adjustments to increase comfort at lower energy cost

These combined behaviors reduce runtime without meaningfully affecting comfort for most households.

Sensors and occupancy detection

You’ll find two forms of occupancy awareness: built-in radar occupancy and optional remote SmartSensors. The radar sensor detects presence near the thermostat and can preheat or precool when you’re approaching the home.

SmartSensors detect which rooms are occupied and feed that data back to the thermostat for better whole-home comfort — so bedrooms aren’t over-conditioned while living areas are used.

SmartSensors: room-level control

You’ll be able to add ecobee SmartSensors (sold separately) to detect motion and temperature in rooms away from the thermostat. This helps eliminate hot or cold spots in the house by prioritizing occupied rooms.

If you want consistent comfort in different rooms at different times of day, adding a few sensors is a smart move.

Built-in radar occupancy and preconditioning

You’ll notice the built-in radar isn’t just for telling the unit when someone is home; it’s used to preheat or precool before you arrive. That means your home can reach the desired temperature right when you walk in, not minutes later.

This intelligent behavior relies on presence detection plus historical patterns to anticipate arrival times and adapt dynamically.

How preconditioning works

You’ll see the thermostat:

• Detect when you’re away and reduce conditioning
• Recognize returning presence patterns
• Use radar to detect approach and begin conditioning early

This feature is especially useful if you want comfort upon arrival without constantly keeping the system running.

App, scheduling, and learning capabilities

You’ll control the thermostat via the ecobee app on your phone, tablet, or Apple Watch. The app provides scheduling tools, energy reports, and remote control. The thermostat learns your preferences and schedule to minimize manual adjustments over time.

You’ll also be able to set specific hold temperatures for special situations and override the learned schedule when needed.

Scheduling and learning

You’ll benefit from:

• A simple scheduling interface to set wake, away, sleep, and home modes
• Adaptive learning that refines schedules based on your adjustments
• Automatic adjustments for humidity and occupancy

This hybrid approach gives you both automation and direct control, depending on how hands-on you want to be.

Voice assistants and smart home integration

You’ll appreciate that the device works with Siri, Alexa, and Google Assistant, so you can use voice commands from your phone, smart speaker, or other devices. It also integrates with many smart home ecosystems for coordinated automation.

If you’re invested in a platform like Apple HomeKit or Amazon Alexa routines, the ecobee integrates smoothly and lets you include thermostat actions in scenes and routines.

Examples of voice and automation

You’ll be able to:

• Say “Hey Siri, set temperature to 72°” or use Alexa/Google commands
• Include climate control in home/away or sleep scenes
• Control the thermostat through routines triggered by sensors or geofencing

That flexibility makes it easy to automate comfort around your lifestyle.

Power Extender Kit (PEK) and Trim Kit

You’ll be relieved the PEK is included. Homes without a C wire often have trouble powering advanced thermostats; the PEK resolves that by providing the required common connection at the furnace or HVAC control board.

The Trim Kit cleans up the wall appearance where the old thermostat left paint or holes, producing a professional-looking install.

Why the PEK matters

You’ll gain:

• Simple retrofit capability in many older homes
• Avoidance of battery reliance or additional wiring jobs
• A neater installation that maintains full functionality

If you’re comfortable with basic furnace-side wiring, the PEK installation is straightforward and usually takes only a few minutes.

Display, controls, and user experience

You’ll find the touchscreen bright, responsive, and easy to navigate. The UI is clean and intuitive, with large icons and straightforward menus for manual overrides and quick changes.

Physical controls are minimal since the touch interface handles most actions, and the ecobee app mirrors many on-device features so you can control things remotely.

Daily use impressions

You’ll enjoy:

• Quick temperature changes via touch or app
• Clear status screens for current temp, setpoint, humidity, and occupancy
• Smooth transitions between automatic and manual modes

Overall, the daily user experience feels polished and modern.

Maintenance and reliability

You’ll appreciate that the thermostat is hardwired so you won’t replace batteries. Reliability depends on network stability for advanced features, but basic HVAC control remains local even if Wi-Fi is unavailable.

ecobee has a track record of stable hardware and software updates that add features and fix bugs over time.

What to expect long-term

You’ll likely experience:

• Minimal maintenance because the unit is hardwired
