Homes in Ajax: What We See
Ajax has older homes in South Ajax and along the waterfront, 1980s and 90s neighbourhoods in Central Ajax, and newer homes in Audley North and Northeast Ajax. Most homes are forced-air with a furnace and central AC, which makes them a good fit for a hybrid heat pump at replacement time.
What We Usually Recommend in Ajax
| Your home | What usually fits | Learn more |
|---|---|---|
| Ducted home with an aging furnace and AC | Hybrid heat pump paired with a high-efficiency furnace (heat pump rebates may apply) | Heat pump installation · Hybrid systems |
| Newer home on its original builder furnace and AC | Furnace and AC replacement, or a hybrid heat pump, sized from a heat-loss calculation | Furnaces · Air conditioners · Hybrid |
| Basement apartment or second unit | A separate ductless heat pump so the unit has its own heating, cooling and thermostat | Single-zone ductless |
| Addition, sunroom or finished attic | Single-zone ductless heat pump; no new ductwork needed | Single-zone ductless |
Every home is different. We confirm the right system after a site visit or a review of photos, and quote it in writing before any work starts.
