Heat Pump Installation in Markham
The process, sizing, timeline, costs and rebates — everything you need before you install.
The short answer: Heat pump installation in Markham starts with a free in-home assessment to size the system correctly, followed by selecting the right model (often a cold-climate or dual-fuel setup for Ontario winters), removing the old equipment, and installing and testing the new unit — usually in one day. Rebates and financing can offset much of the cost.
A heat pump heats and cools your home from one efficient system, and getting it installed correctly is what makes it perform. If you're planning heat pump installation in Markham, this guide walks through the full process — sizing, model choice, timeline, cost, and the rebates that bring the price down — so you know exactly what to expect.

Key takeaways
- Correct sizing (a load calculation) is the single most important step — not a rule of thumb.
- Most Markham homes do well with a cold-climate heat pump or a dual-fuel setup.
- A typical install is completed in a single day.
- Rebates and financing can significantly lower the upfront cost.
- Professional, permitted installation protects your warranty and safety.
Why Markham Homes Choose a Heat Pump
A heat pump moves heat instead of burning fuel, so it delivers efficient heating in winter and cooling in summer from a single system. For Markham's swing between deep-freeze winters and humid summers, that means year-round comfort with lower energy use — which is why heat pump installation in Markham has become such a popular upgrade. Many homeowners pair it with a backup furnace for the coldest days, which we cover below. To see how it compares with a traditional setup, read our guide on heating and cooling options.
Heat Pump Installation in Markham: The Process
A proper installation follows clear steps — here's what a professional job looks like from start to finish:
- Free in-home assessment. A technician measures your home and calculates the heating and cooling load — the basis for correct sizing.
- System recommendation & quote. You get the right model and size, plus an up-front price and any rebates you qualify for.
- Removal of old equipment. The old air conditioner or furnace components are safely disconnected and removed.
- Installation. The outdoor unit, indoor coil or air handler, refrigerant lines, and electrical and controls are installed to code.
- Testing & walkthrough. The system is charged, tested, and balanced, and the technician shows you how to run it before leaving.
Every job is permitted and performed by trained technicians — see our full heating and cooling services.
Choosing the Right System & Size
Two decisions shape the result: the type of system and the size.
- Cold-climate heat pump. Built to heat efficiently well below freezing — a strong fit for most Markham homes.
- Dual-fuel (hybrid). Pairs a heat pump with a high-efficiency gas furnace; the heat pump handles most of the season and the furnace covers the coldest snaps.
- Ductless (mini-split). Ideal for homes without ductwork, additions, or specific zones.
Sizing matters more than anything. An oversized unit short-cycles and wastes energy; an undersized one struggles in a cold snap. That's why a proper load calculation — not a rule of thumb — is essential, and it's included in your assessment.
Cost, Rebates & Financing
The cost of heat pump installation in Markham depends on your home's size, the system type, and the complexity of the install. Three things make it manageable: rebates on qualifying energy-efficient heat pumps, financing that spreads the cost into predictable monthly payments, and the energy savings the new system delivers over time. Rebate programs change, so check current federal and provincial incentives through Natural Resources Canada and ask us which apply to your project.

Frequently Asked Questions
How long does heat pump installation take in Markham?
Most standard installations are finished in one day. A dual-fuel system, a ductless multi-zone setup, or electrical upgrades can add time. Your technician confirms the exact timeline during the free in-home assessment.
What size heat pump do I need?
The right size comes from a load calculation that accounts for your home's square footage, insulation, windows, and layout — not a rule of thumb. Correct sizing is essential: too big short-cycles and wastes energy, too small struggles in the cold.
Do heat pumps work in Markham winters?
Yes. Modern cold-climate heat pumps heat efficiently well below freezing. For the coldest days, many Markham homes choose a dual-fuel setup that pairs the heat pump with a backup gas furnace for reliable heat all winter.
Are there rebates for heat pump installation?
Often, yes. Federal and provincial energy-efficiency programs frequently include incentives for qualifying heat pumps, though they change over time. We help you check current programs and apply the ones your project qualifies for.
Can a heat pump replace my furnace and AC?
A heat pump can replace both, since it heats and cools from one system. In colder areas many homeowners keep a backup furnace in a dual-fuel setup, so the heat pump does most of the work and the furnace covers extreme cold.
