Google Nest in Québec: first, is your heating 24 V?

No Google Nest thermostat works on 120 or 240 V electric baseboards. On a furnace, a central heat pump or a boiler controlled at 24 V, we tell you which one to pick, and whether the sensor will work with it.

01 · Compatibility checker

Google’s checker looks at your wires. Ours starts with your heating.

Five questions, a verdict built from Google’s documents. We confirm everything at the on-site estimate, before ordering.

1What heats the house?
2Must the thermostat also control a humidifier, a dehumidifier or ventilation?
3Do you want to measure the temperature in other rooms (sensors)?
4How many heating stages (W1, W2, W3 terminals)?
5Is there a C (common) wire at the current thermostat?

02 · What we sell

Two thermostats and a sensor. The sensor only goes with the Learning.

Specs from Google’s Canadian pages. Both thermostats appear on the ENERGY STAR list under their exact model number.

06 · Frequently asked questions

What people ask us about Google Nest

Does a Google Nest thermostat work with electric baseboards?

No. Baseboards run on 120 or 240 V, and Google excludes all of its thermostats from high-voltage systems. Baseboards need an electronic thermostat built for that voltage.

Does it work with a central heat pump?

Yes, if it is controlled at 24 V. The Learning (4th gen) handles O/B, auxiliary (AUX) and emergency (E) heat. The Nest Thermostat handles one stage plus auxiliary or emergency heat, but Google then requires a C wire or the Power Connector.

Do I need a C wire?

With the Learning (4th gen), Google says a C wire or the Power Connector is needed in less than 1% of cases. With the Nest Thermostat, it is required on a heat pump, a zoned system, a heat-only or a cool-only system.

Does the T5000SF sensor work with the Nest Thermostat?

No. Google states that the Nest Thermostat is not compatible with any Nest temperature sensor. The sensor works with the Learning (3rd and 4th gen) and the Nest Thermostat E.

How many sensors can I install?

Up to 6 per thermostat and 18 per home, according to Google. The sensor links to the thermostat over Bluetooth Low Energy, within about 15 m, and runs on a CR2 battery.

Learning or Nest Thermostat: which one?

The Nest Thermostat is enough for a simple 24 V system. Choose the Learning (4th gen) if you want sensors in other rooms, need to control a humidifier or ventilation, or have three heating stages.

Is there a rebate for a Google Nest thermostat?

Yes, if your home is heated by a central natural gas system from Énergir: $100 per thermostat on the PEE-104 list, up to 75% of the price, applied for with Énergir within 30 days of purchase. Hydro-Québec offers no rebate for Nest thermostats, and LogisVert does not cover thermostats.

Does Google Nest work with Hydro-Québec’s Hilo?

No. Hilo states that its solution is not compatible with Google Nest devices.

Is the device available in French?

Yes. Google lists French, English and Spanish for the Learning (4th gen) and the Nest Thermostat.

What is the warranty?

According to Google: 2 years for the Learning (4th gen) sold at retail, 1 year for the Nest Thermostat, 1 year limited for the sensor.

My old Nest Learning no longer connects. Why?

Since October 25, 2025, Google no longer supports the 1st and 2nd gen Learning thermostats in its apps. The device keeps its schedules and on-device controls, but has no remote control or updates.

Is Nest Seasonal Savings available in Québec?

No. Google states that the feature is available in Canada except in Québec.

How much does an installed Google Nest thermostat cost?

Pricing is on quotation, based on your system and wiring. The on-site estimate is free.
