Smart Thermostat Installation in Mississauga

Realistic Mississauga savings: 8-15% on heating bill, 5-10% on cooling. On a typical $1,800/yr gas + electric HVAC bill = $150 – $250/yr savings. The Ecobee Premium pays back in 2-3 years; the basic Lite in under 1.5 years (with $75 HRS rebate factored).

Yes, but we'll need to add a C-wire (best) or use a Power Extender Kit (Ecobee compatible). Quote includes either. Power Extender ~$60 added; C-wire pull ~$200-$400 added (ESA permitted).

Yes — included free at install. We provide a completion certificate, invoice with equipment model, and submit the HRS form. Rebate is paid to homeowner directly by Enbridge/Save-on-Energy administrator, typically 6-10 weeks after submission.

Standard single-stage furnace/AC: yes (all brands). 2-stage furnace/AC: yes (Ecobee Premium, Nest Learning, Honeywell T10 specifically). Heat pump: yes with proper config (heat pump + aux heat support — Ecobee Premium / Nest Learning / Honeywell T9). Hydronic boiler: yes (Honeywell T9 best). We verify at consultation.

Mostly yes if you have the C-wire. The HRS rebate doesn't require professional install (you can DIY and still claim). BUT — if anything goes wrong (HVAC short, blown transformer), warranty / repair is on you. ECRA/ESA permit IS required if you add new wiring. We recommend pro-install for any home with 2-wire setup, old wiring, or heat pump.

It will operate the HVAC normally (manual & scheduled modes), but smart features (remote control, learning, alerts) require WiFi. Ecobee Premium also has voice control built in (Alexa) — needs WiFi.

30-45 min for direct swap with existing C-wire. 90-120 min if C-wire pull required (one ESA permit + inspection visit, but often we do it same day).

Yes. Each zone needs its own thermostat connected to the zone control board. We bundle 2-4 thermostat installs at the same time for $850-$1,400 depending on brand. Honeywell T9 is purpose-built for multi-zone (single hub, multiple room sensors AND zone thermostats).

Ecobee — best IAQ features, room sensors, built-in Alexa, free to manage. Nest — slickest UI, learning algorithm, premium look-and-feel, requires Google account. Honeywell — best for multi-zone and hydronic, T9 is the right pick for radiant/boiler heat. We recommend Ecobee Premium as default unless your HVAC dictates otherwise.

Ecobee + Nest both work with Amazon Alexa, Google Home, Apple HomeKit, SmartThings. Honeywell T9 works with Alexa + Google Home (HomeKit support via Resideo app). All major smart home ecosystems supported.

Thermostat reverts to off until power restores. No HVAC operation during outage. Schedule preserved (saved to device + cloud). If your home has a standby generator (see our Standby Generator Installation page), normal operation continues throughout the outage.
