The Mississauga home energy guide
Mississauga was built in a hurry — most of it between 1970 and 2000 — and the shortcuts of fast subdivision construction are exactly what an audit is built to find.
The housing stock, read like an auditor
The city's core profile is the 1970s–90s two-storey: R-12-ish walls, R-20 to R-32 attics, builder-grade ductwork, and the infamous room over the garage. Older pockets in Port Credit, Streetsville, and Cooksville add post-war bungalows, while newer infill runs tighter but often under-ventilated. Nearly everything is gas-heated, which makes the heat-pump question a comfort-and-cooling decision as much as a bills one.
What audits find in Mississauga
- Cold rooms over garages from missed floor insulation and duct runs through unconditioned space
- Second floors that roast in July — attic heat load plus leaky duct runs
- Attic top-ups that still clear the bar at today's install prices
- Poly-era homes with condensation issues traced to ventilation, not windows
- Oversized builder furnaces short-cycling toward early failure
Tests to ask for by name
- Blower door test — the leakage number that reorders your plan
- Infrared scan — finds the empty walls without opening them
- CSA F280 heat-loss calculation — before any heat pump quote
- Radon test — Health Canada recommends it for every home
Run the planner for the full test list matched to your house — it carries into your audit request automatically.
The rebate angle
The Home Renovation Savings assessment path fits Mississauga's profile: two or more upgrades (typically attic + air sealing, or insulation + windows) unlock the $600 assessment rebate plus up to $7,700 in insulation support. Duct testing is the add-on to request by name here — it explains most of the city's comfort complaints.

Local questions
Why is the room over my garage always cold?
Because its floor faces unheated space and its ducts run through the same cold zone; builders routinely under-insulated both. The fix ladder runs duct sealing → floor insulation → a ductless head if needed — the audit's thermal scan shows which step yours needs.
Is a heat pump worth it in a gas-heated Mississauga home?
On pure bills, modest at current gas prices; as an AC-replacement decision, strong. When your air conditioner dies, the incremental cost of a heat pump over a new AC — minus up to $12,000 in rebates — usually makes it the obvious replacement.
