In short
Ontario's Home Renovation Savings Program pays $100 toward a qualifying smart thermostat installed as part of an eligible upgrade. The device has to be an approved model, properly wired and claimed with the rest of the project. Local hydro utilities deliver this same province-wide program rather than running separate thermostat rebates of their own.
How much you can get
- Qualifying smart thermostat with an eligible upgrade $100
- Thermostat claimed on its own, with no other work See the program page
- Utility-run thermostat promotions See the utility's own offers page
- Adding a common wire where none exists Not a rebate — a wiring cost on your invoice
Who qualifies
- The thermostat model appears on the program's qualifying products list.
- It is installed as part of an eligible project rather than sold as a standalone accessory.
- The home meets the same occupancy and property-type rules as the rest of the program.
- The device is installed and configured correctly for the equipment it controls.
- The invoice itemizes the thermostat rather than burying it in a lump-sum line.
We install a lot of these, and the rebate is rarely the reason anyone should. Treat $100 as a discount on a device you already wanted, and spend your attention on whether it suits your system.
What the $100 covers and when it is paid
It is a per-thermostat amount, claimed with the project it belongs to, on an approved model. The amount was raised this year, so older program printouts and stale contractor spreadsheets understate it. Bundled with a heat pump or furnace install, it is a straightforward extra line on the same claim. Standalone claims are a different question — check the program page, because the rules around single-measure thermostat claims are the ones that change most often.
Your wiring decides whether a smart thermostat will work at all
Nearly every smart thermostat needs continuous 24-volt power, which means a common wire (the C-wire) back to the furnace or air handler. Houses wired in the 1950s and 1960s frequently ran four conductors and no more, and that is the single most common reason a thermostat that looked perfect in the box will not stay powered.
- No C-wire: options are pulling new thermostat cable, fitting an adapter at the board, or choosing a model with its own power arrangement.
- Electric baseboards: these are line voltage, and a standard 24-volt smart thermostat will not control them — you need a line-voltage model rated for the circuit, one per zone.
- Condo fan coils: many use proprietary or two-wire controls, and swapping to a consumer thermostat can breach the building's rules as well as break the coil's control logic.
- Hydronic boilers with zone valves: workable, but each zone needs its own compatible control and the wiring is not the same as a forced-air job.
- Millivolt systems on old gravity units: not compatible without an interface, and usually a sign the appliance itself is due.
Heat pumps and dual fuel need more than a basic thermostat
A heat pump thermostat has to drive a reversing valve (the O or B terminal) and stage auxiliary heat sensibly. On a dual-fuel system it also has to decide when to stop using the heat pump and start using the gas furnace — the switchover or balance point — and that setting is worth more to your bills than any rebate.
Set the switchover too high and you burn gas on mild days for no reason. Set it too low and the heat pump grinds away in deep cold at poor efficiency. We set it against the equipment's published capacity curve, not a factory default.
What a smart thermostat actually does for you
The honest version: scheduling and setback save energy, remote access saves aggravation, and usage reports tell you when something is running longer than it should. What it will not do is fix an oversized furnace, a leaky return, or a room that has always been cold. For that last one, see why one room is always cold.
Where local utilities fit in
Burlington Hydro, Oakville Hydro and Alectra deliver the province-wide Save on Energy programs; they do not each run a separate thermostat rebate. If a utility is running its own promotion at any given time, it will be posted on that utility's offers page — check there rather than taking a salesperson's word for it.
If you want the thermostat done as part of a furnace or heat pump install, we handle the wiring and the claim together — book a visit or read the smart thermostat benefits guide first.
How ZK Mechanical helps
- Check the wire count at the thermostat and at the board before recommending a model, not after buying one.
- Pull new thermostat cable when the run allows it, instead of relying on an adapter as a permanent fix.
- Configure heat pump staging and the dual-fuel switchover to the equipment's actual capacity curve.
- Itemize the thermostat on the invoice so the claim is not held up.
- Say when a programmable thermostat you already own is fine and the upgrade is not worth it.
Frequently asked questions
Can I claim the rebate if I install it myself?
Program rebates are built around qualifying equipment installed as part of an eligible project with proper documentation. A self-installed device bought at retail generally has nothing to attach a claim to.
Which models qualify?
The qualifying list is maintained by the program and changes as manufacturers release new models, so check it before purchase. Mainstream Wi-Fi thermostats from established brands are the usual candidates.
Will a smart thermostat work with my baseboard heaters?
Only a line-voltage model designed for the job. Standard smart thermostats switch a low-voltage signal and will be destroyed by a baseboard circuit — and you need one per heated zone, which changes the economics.
Do I need Wi-Fi for it to run my heating?
No. The thermostat keeps its schedule and controls the equipment without a connection. You lose remote access, notifications and usage reporting until it is back online.
Is $100 worth the paperwork?
On its own, barely. As one line on a heat pump or furnace claim we are already filing, it costs you nothing extra, which is the sensible way to treat it.
