HVAC System Health Monitor

What is HVAC System Health Monitor?

HVAC System Health Monitor is a feature on Nest thermostats that can help homeowners identify potential issues with eligible heating, ventilation, and air conditioning (HVAC) systems. If a potential issue is detected, Google Nest will send the homeowner an alert via email and/or a Google Home app notification.

How HVAC System Health Monitor Works

Sometimes, HVAC systems show warning signs that they are having issues. For example, if it takes longer than usual to cool a home, there might be a problem with the cooling system (A/C). Google Nest may send the homeowner an email alert or a Google Home app notification if a warning sign is detected. The alert email or notification will tell the homeowner what their Nest thermostat has noticed and which system (heating or cooling) may be affected.

If a Pro ID was entered during the setup of a Nest thermostat, the homeowner will also be shown contact information for the contractor company that installed it. Important: HVAC System Health Monitor is not meant to replace the diagnosis of a qualified HVAC professional. We make no endorsement, representation, or warranty about the health of the HVAC system. There may still be other issues with the HVAC system that may not trigger an alert to the homeowner.

How do you enable the HVAC System Health Monitor?

System Health Monitor will only include the contractor’s contact information if they are a registered Nest Pro. A person with legal signing authority for the contractor company can register for a Pro ID at g.co/nestpro. During enrollment, the legal signing authority must opt in to have the company’s info surface to the customer.

Post enrollment, the administrator of the Nest Pro account can also opt in by adjusting the Settings under “System Health Monitor Repair Requests.” HVAC System Health Monitor alerts will surface the information of a contractor company if they are enrolled in HVAC System Health Monitor and a Pro ID is entered on the thermostat.

If a Google account is used, the homeowner will always get urgent alert notifications, but they can opt out of urgent email alerts, early warning emails, or Google Home app notifications by turning them off within the app. If a homeowner uses a non-migrated Nest Account, they can only get urgent or early warning emails. The homeowner can turn off early warning emails by opting out in the footer of those emails. However, homeowners can

Types of Alerts

If a Nest thermostat detects a potential issue that may require immediate attention, Google Nest will send the homeowner an urgent alert as soon as a problem is detected. For example, if a homeowner turns on their heating system but their home becomes colder, this may indicate a severe HVAC problem. If Google Nest detects an issue that should be fixed soon, an early warning alert will be sent to the homeowner within a week of detecting the problem.

For example, if a homeowner’s A/C is running longer than usual, this may indicate that it needs to be serviced. Important: HVAC System Health Monitor is not meant to replace the diagnosis of a qualified HVAC professional. We make no endorsement, representation, or warranty about the health of your HVAC system. You may still experience issues with your HVAC system that we don’t alert you to.

Key Features and Functionality

Temperature Schedule

A user can create or adjust the temperature schedule of the thermostat in the Google Home app. Temperature presets let you customize temperatures for when you’re home, away, sleeping, and more. You can add a preset to the schedule or adjust the temperatures of each preset. You can also set the thermostat to “hold” a specific preset or current custom setpoint or preset for an extended period of time.

There are three ready-made presets that the thermostat will start with: Comfort, Sleep, and Eco. The user can adjust the temperatures of these presets or add their own custom presets when they add the thermostat to the Google Home app. If a user installs a Nest Temperature Sensor using the Google Home app, they will also be given the option to schedule when the thermostat observes a particular sensor.

Smart Schedule

Smart Schedule learns from users’ temperature adjustments and presence patterns over time to create a customized temperature schedule. The Nest Learning Thermostat (4th gen) will suggest changes to users’ schedules to optimize them for comfort and energy savings. Users can allow the Nest Learning Thermostat (4th gen) to automatically apply these changes, review first, then accept or reject suggestions, or disable Smart Schedule completely. Smart Schedule learns the most during the first week of use, but it will never stop learning.

Users will always be notified when the thermostat has made a change to their schedule, even if “Automatically Apply” has been chosen. The thermostat will also visually indicate on the thermostat and in the app when it is “learning” from a user’s manual temperature adjustment. The user can always check the History tab in the Google Home app to see when a change has been made.

A user can reset smart schedule learning if their habits or schedules have changed significantly, and the thermostat will begin to learn their preferences from that point on. Smart Schedule will only adjust the setpoints or scheduled time of the ready-made presets: Comfort, Sleep, and Eco. In the future, we may add the capability to adjust custom presets, too.

Notes: There are other features mentioned in this document that could change when the thermostat is running or not running. Any Google Home Member can accept a Smart Schedule suggestion. Make sure notifications are enabled for the Google Home app so the user gets notified of any changes.

Energy Shift – Time of Use

Energy Shift is a combination of features that can allow the thermostat to integrate with energy savings initiatives from their local utility provider. There are three main features combined under Energy Shift: Time of Use, Cleaner Energy, and Rush Hour Rewards. “Time of Use” allows a user to prioritize using cheaper energy if their utility provider offers Time of Use rates or billing.

The user can add a rate code from their utility directly in the Google Home app, which will inform the thermostat when the price of energy is more expensive for the user. When enabled, the thermostat can adjust when the system runs to avoid using energy when it is more expensive, where possible. The user will be notified of any adjustments to their schedule or setpoints, and they can also see a summary of adjustments in the Time of Use page of the Google Home app.

If a user does not have a Time of Use rate available from their utility, they can still set a manual “Peak Period” for their thermostat to reference. This could be useful for customers with solar or battery systems, or for a utility that hasn’t integrated with Google services yet, but still has a Time of Use rate available to customers.

Energy Shift – Prioritize Cleaner Energy and Rush Hour Rewards

Energy Shift is a combination of features that can allow the thermostat to integrate with Energy Savings initiatives from their local utility provider. There are three main features combined under Energy Shift: Time of Use, Cleaner Energy, and Rush Hour Rewards. The “Prioritize Cleaner Energy” feature is available to customers whose utility integrates with the Renew Home services and provides real-time information about the source of power generation.

When enabled, the thermostat can adjust the schedule by 30 minutes to prioritize running the HVAC system when the power available on the grid is produced by “cleaner” energy sources like solar and wind. Rush Hour Rewards is a program available through certain utility companies that allows a user to enroll their thermostat with the utility and give permission to adjust their heating or cooling setpoints if the grid is experiencing a “rush hour” from abnormally high energy consumption.

Users who enroll in this program are usually given a rebate or bill credit of some sort, although each utility partner is different. Check out this link for more information. Note: Users are never locked out from controlling their thermostat, and they can always change their temperatures when enrolled in any utility program through a Nest thermostat.

Seasonal Savings

Seasonal Savings is a feature that users may opt into each summer or winter. The goal of Seasonal Savings is to find energy savings without sacrificing comfort. The feature gradually adjusts preset temperatures over a 3-5 week period. After making a small adjustment toward saving energy, Seasonal Savings will wait for the user to experience the new temperature before making another adjustment.

If Seasonal Savings detects that users have become uncomfortable (based on the frequency of requests for more heating or cooling), then it will stop making adjustments toward saving energy and return the preset to a comfortable temperature.

Note: If a device does not have a schedule, and a user opts that device into Seasonal Savings, a basic schedule with only Sleep and Comfort presets will be created.

Natural Heating and Cooling

Natural Heating and Cooling determines when to pause heating or cooling and to allow the temperature to naturally rise or fall. For example, on a sunny morning, the thermostat might pause heating because the sun is helping to keep the house warm. Similarly, on a cool evening, the thermostat might pause cooling and let the temperature fall naturally.

The thermostat uses outdoor temperature data to determine when to activate Natural Heating and Cooling. The feature can be enabled or disabled using the Google Home app. The thermostat will show a Natural Heating/Cooling message when the feature is actively preventing heating or cooling.

Fan and Ventilation Control

The Nest Learning Thermostat (4th gen) can control the HVAC system fan if there is a wire allowing independent control. The fan can be scheduled to run for 15-60 minutes each hour every day. It can also be manually engaged for a set amount of time. If there is a multi-speed fan, the user will be prompted to choose a fan speed when manually activating the fan.

If there is a ventilation system configured on the thermostat, the user will be able to manually activate it with a timer alone or with the system fan. If the ventilation system requires the fan to be activated, the user will only be shown the option to activate the fan or the fan ventilation. When ventilation is enabled, the user will need to set the “Required daily ventilation” from 2 to 24 hours. The default for “required daily ventilation” is 18 hours.

Smart Ventilation

The Smart Ventilation feature uses the outdoor temperature, air quality, and user behavior to determine how much ventilation to use and when it should be used. For example, this feature may not run the ventilation system if the outdoor air quality is poor.

It can also take outdoor temperatures into account and bring in outdoor air that is warmer or cooler than indoors as necessary, rather than running the heating or cooling system. When enabled, this feature will activate a ventilation system at varying times throughout the day while still meeting the “Required Daily Ventilation” threshold set by the user.

Adaptive Comfort and Adaptive Eco

The Adaptive Eco feature can help a user save energy when they are away without sacrificing their comfort when they return home. Using the home’s past heating and cooling performance and the latest forecasted weather, Adaptive Eco can adjust the Eco temperatures to reduce heating and cooling while still allowing the home to quickly return to a comfortable temperature when the user returns home. Adaptive Eco will only take effect during Auto-Eco periods.

Therefore, to use Adaptive Eco, a user must first set up a Home & Away routine in the Google Home app to set the thermostat to Eco temperatures when they are away. Adaptive Comfort can dynamically adjust the Comfort temperatures to account for non-temperature factors, conditions as indoor humidity and forecasted weather. This allows the thermostat to respond to changing conditions in order to keep the home comfortable. The user can turn this feature on or off using the Google Home app.

Early On

This feature allows the user to schedule their thermostat around when they would like to reach a temperature instead of when they want to start running their system. A user can choose to enable Early On for cooling and heating setpoints when the home is occupied. They can also choose how long the thermostat can pre-heat the home overnight. The user can also enable Early On for when they are returning home, which will allow the thermostat to pre-heat or pre-cool while the user is away to reach the next scheduled temperature preset before they arrive. This requires Home & Away Routines to be turned on for the thermostat.
