Heat pumps in London: what makes sense here

London is one of the larger heat-pump installation markets in Ontario, with multiple licensed contractors covering the metro and the surrounding communities — enough competition that comparing three quotes is realistic.

London's housing stock and climate context

London's residential stock is predominantly Mix: 1900-1930 in Old North and Wortley Village, 1960s-90s in the rest, which shapes both heat-loss characteristics and retrofit complexity. Snowbelt city — Lake Huron lake-effect snow events bring substantial February-March precipitation.

The neighbourhoods where this comes up most often include Old North, Wortley Village, Byron, Masonville, and Hyde Park. Housing vintage varies enough across them to change the equipment answer, which is why a load calculation beats a rule of thumb here.

The typical install scenario in London

Older Old North homes often pair envelope work with heat pump retrofit; newer Masonville and Byron stock are direct gas-to-dual-fuel conversions.

What to ask your installer in London

  • Manual J load calculation using London's 99% winter design temperature, not a square-footage rule of thumb. More on this →
  • AHRI matched-system certificate for the proposed indoor + outdoor combination — the document rebate programs ask for.
  • Itemized rebate calculation showing federal + provincial + utility stack specific to your address.
  • Outdoor unit placement appropriate for London's conditions — elevated brackets, salt-air corrosion coatings, snow-clearance considerations where applicable.

Common questions

How much does heat pump installation cost in London?

London pricing follows Ontario's provincial range: $12,000–$19,000 for a ducted air-source heat pump and $4,000–$8,500 for a single-zone ductless system. The Ontario row of the cost guide shows how those figures are built.

Are there licensed heat pump installers in London?

Yes. The practical question is not whether they exist but how to verify one: check the provincial licensing registry, and ask for the AHRI certificate on the specific matched system being quoted. Provincial trade-licensing registries and the HRAI directory both cover London.

Which rebates can I claim as a London homeowner?

Programs that can apply in Ontario: Home Renovation Savings — cold-climate air-source heat pump ($1,250 per ton, up to $7,500), Home Renovation Savings — cold-climate air-source heat pump (gas-heated home) ($500 per ton, up to $2,000), Home Renovation Savings — ground-source heat pump ($2,000 per ton, up to $12,000), Home Renovation Savings — ground-source heat pump (gas-heated home) (up to $3,000). Separately, the federal National Heat Pump Rebate will add up to $10,000 for households below the median income, or $2,000 for others. It opens in early 2027 and covers eligible installs from November 1, 2026. The provincial rebate stacking guide walks through worked examples.

How long does installation take in London?

Same as the provincial average: 1-2 days for a ducted retrofit, 1 day for ductless single-zone, 2-3 days for ductless multi-zone. Oil-to-heat-pump conversions take 2-3 days including tank decommissioning. Equipment delivery delays in London are minimal — most installers carry common cold-climate models in stock.
