No smart thermostat suits every home, because your heating system decides. A 24 V furnace, boiler or heat pump takes a mainstream model, while electric baseboard heat on 120 or 240 V needs a line-voltage one. Check seven things before you buy. Pixl installs a standard model for a posted $129, plus $50 if a C-wire adapter step is needed.
PCBy the Pixl Canada install team. Checked November 1, 2026. 7 min read.
- Seven checks, in order
- Five models with manufacturer specs
- Matter, humidity, heat pump and C-wire explained
- Installed totals calculated from list and posted prices
- Heating system and voltage come first. A 24 V thermostat is not for baseboard heat.
- Heat pump support, humidity control and C-wire behaviour differ by model.
- Google lists Matter for both Nest models checked here. ecobee’s pages do not mention it.
- Installed total = list price + $129, plus $50 if the adapter step is needed.
What should you check before you buy a smart thermostat?
Work through these in order. The first two can rule a model out completely.
| Check | What to ask | Where to verify |
|---|---|---|
| 1. Heating system and voltage | Is the wiring 24 V, or two thick wires on 120 or 240 V? | Photo of the wires, the thermostat label and the maker’s compatibility checker |
| 2. Heat pump, boiler or second stage | Does the datasheet list O/B, auxiliary heat and your number of stages? | Datasheet terminal list |
| 3. Power: C-wire or extender | Does it need a C wire, or ship with a power accessory? | Maker’s C-wire page, then our C-wire guide |
| 4. Cooling and humidity | Can it run your AC, humidifier, dehumidifier or HRV, or only sense humidity? | Accessory terminals in the datasheet |
| 5. App, ecosystem and Matter | Does it work with the voice assistant and app you already use? | Maker’s compatibility list, then Matter explained |
| 6. Account, subscription and security | Which account, and which features need a subscription? | Product page and privacy terms |
| 7. Rebates and total cost | Does your utility or city list this model? What is the installed total? | Program site, then thermostat rebates in Canada |
Not sure which of the seven applies to you?
Text a photo of the wires behind your thermostat. We tell you whether it is a standard $129 swap before you book.
Which type fits which heating system?
The full matching table, with baseboard load maths, is in which smart thermostat for your heating system.
| If you heat with | Shortlist | Key warning |
|---|---|---|
| Gas, propane or oil furnace, with or without AC | Mainstream 24 V smart thermostat | Check the C wire; with only two thin wires expect an adapter step |
| Heat pump or dual-fuel | 24 V model with O/B and auxiliary heat support | Support differs by model and by number of aux stages |
| Electric baseboard, in-wall or radiant ceiling | Line-voltage smart thermostat | Add up heater watts; wiring is electrical work |
| Millivolt (gas fireplace or older wall heater) | Millivolt-rated thermostat only | Most smart thermostats do not support it. Read the datasheet |
How do a few well-known models compare?
Five examples, not a ranking. Every figure comes from the maker’s own Canadian page on 1 November 2026, and list prices change.
| Model | Heating it controls | Smart home | Notable features | List price |
|---|---|---|---|---|
| Google Nest Learning Thermostat (4th gen) | 24 V systems incl. heat pumps with aux and emergency heat; humidifier terminals | Google Home and Matter; WiFi 2.4 and 5 GHz | Motion, temperature, humidity and light sensors; ENERGY STAR certified | CA$379.99 (Google Store) |
| Google Nest Thermostat | 24 V furnaces, ACs, boilers and heat pumps (one stage plus aux or emergency) | Matter certified; Hey Google and Alexa; WiFi 2.4 and 5 GHz | Temperature, humidity and motion sensing | CA$179.99 (Google Store) |
| ecobee Smart Thermostat Enhanced | 24 V incl. heat pumps (2H/2C plus one aux stage), boilers; one accessory wire | HomeKit, Alexa, Google Assistant, SmartThings. Matter not listed | 4 in. touchscreen, radar occupancy sensing, humidity | $249.99 (ecobee.ca) |
| ecobee Smart Thermostat Premium | As Enhanced, with two aux stages and one 1- or 2-wire accessory | As Enhanced, plus Siri or Alexa built in. Matter not listed | Air-quality monitoring; some security features need a subscription | $329.99 (ecobee.ca) |
| Mysa for Electric Baseboard Heaters (Gen 3) | 120 or 240 V electric heat only: 2,000 W at 120 V, 4,000 W at 240 V | Matter certified; WiFi 2.4 GHz only | Neutral or L2 wire required; no subscription; 5-year warranty | See Mysa’s store |
Mysa’s FAQ on the same page still quotes the older 3,800 W and 1,900 W limits, so read the rating on the model in your box. Google says a C wire or the Nest Power Connector is needed in limited cases (under 1% for the 4th gen), and ecobee says its Power Extender Kit lets most homes install without a C wire. Neither is a promise about your house.
Does Matter or your ecosystem matter for a thermostat?
It matters if your routines live in one app. A Matter-certified thermostat can join several platforms, while a model that lists HomeKit, Alexa and Google Assistant separately relies on the maker’s app for full control. Google says the 4th-gen Learning Thermostat still needs the Google Home app for setup. See Google Home vs Alexa vs Apple Home vs SmartThings and do you need a smart home hub if you are still choosing.
What about accounts, subscriptions and security?
The Canadian Centre for Cyber Security advises unique passwords, updates switched on and smart devices on a secondary network where possible. ecobee lists WPA, WPA2 and WPA3 support and Mysa lists CSA Product Security Level 1. Those are the makers’ statements, not our testing. See guest WiFi and an IoT network.
What does a smart thermostat cost installed?
| Model | List price | With $129 install | If the $50 adapter step is needed |
|---|---|---|---|
| Google Nest Thermostat | $179.99 | $308.99 | $358.99 |
| ecobee Smart Thermostat Enhanced | $249.99 | $378.99 | $428.99 |
| ecobee Smart Thermostat Premium | $329.99 | $458.99 | $508.99 |
| Google Nest Learning Thermostat (4th gen) | $379.99 | $508.99 | $558.99 |
Stores run sales, tax is extra and a rebate can lower the device price. The line-voltage Mysa is left out, because baseboard wiring is outside the $129 swap.
Pixl installs it for $129
Buy a low-voltage model at any store. Pixl removes the old thermostat, labels the wires, mounts and wires the new one, then sets up WiFi, the app and your schedule. Posted price: $129 before tax, +$50 only if your system needs the C-wire adapter step. You get a fixed price from a wire photo and pay after the job. See smart thermostat installation, Nest installation and ecobee installation.
You have a furnace, boiler or heat pump on 24 V wiring.
You heat with electric baseboards or another 120 or 240 V system. Pixl’s $129 covers standard low-voltage swaps only.
Choosing a smart thermostat: frequently asked questions
What is the best smart thermostat in Canada?
There is no single winner, because your heating system decides. Match the voltage first (24 V or line voltage), then check heat pump support, C-wire needs, your ecosystem and any rebate model list.
Do I need a C-wire for a smart thermostat?
Not always. Google says its Nest thermostats are designed to work with or without a C wire, with limited exceptions, and ecobee ships a Power Extender Kit with most models for homes that have no C wire. Check your wires and the maker’s compatibility checker first.
Will a smart thermostat work with my heat pump?
Many do, but support differs by model. Look for O/B (reversing valve) and auxiliary heat terminals in the datasheet, and run the maker’s compatibility checker for dual-fuel or cold-climate systems.
Can I put a smart thermostat on electric baseboard heaters?
Not a standard one. Baseboards run on 120 or 240 V and need a line-voltage thermostat rated for the total heater wattage. That is electrical work, so ask a qualified electrician or your provincial electrical authority.
Does a smart thermostat work with Matter?
Some do. As of 1 November 2026, Google lists Matter for the Nest Learning Thermostat (4th gen) and the Nest Thermostat, and Mysa lists it for its Gen 3 baseboard model. ecobee’s Canadian pages for the Enhanced and Premium list Apple HomeKit, Alexa, Google Assistant and SmartThings, and do not mention Matter.
Can I get a rebate on a smart thermostat?
Often yes, but each program has its own eligible models and heating types. Pick the program first. Our rebate guide covers Ontario, BC Hydro and Red Deer.
Does Pixl install a smart thermostat I bought elsewhere?
Yes, for standard low-voltage swaps: $129 before tax with WiFi and app setup, plus $50 if the C-wire adapter step is needed. Baseboard thermostats are electrical work, so ask an electrician.
Chosen a thermostat?
Send the model and a photo of the wires. You get a fixed price before you book, and you pay after the job.
