Process
A heat pump project, start to commissioning
Every job starts with a conversation and a look at the equipment. You see the options in plain language before anything is booked.
- 1
Load calculation and site review
We calculate heating and cooling loads from the building itself, not from floor area. We also look at ductwork, panel capacity, outdoor unit placement, snow load and drainage.
- 2
Choosing the system type
Ducted, ductless or hybrid? We lay out the options with their trade-offs. Homes with usable ducts often suit a ducted or hybrid system, while additions and rooms with weak airflow may suit a mini split. Our ductless mini split installation page has the details.

Rebate eligibility review
Before you commit, we help you check the conditions that may apply. Rebate eligibility depends on the program, the equipment and your property, so we confirm it rather than assume it.

Installation and electrical work
The outdoor unit goes on a stand that keeps it clear of snow and meltwater. Refrigerant lines are run and pressure tested, and the indoor coil or air handler is connected. Electrical work is done by licensed electrical professionals or trade partners, with permits and ESA notification where required.
- 5
Commissioning
We evacuate the lines, set the charge by the manufacturer method, and test heating, cooling and defrost. We confirm thermostat staging and backup heat changeover, then walk you through the controls. Proper commissioning is what turns equipment into a working system.

Good to know
Choices that shape winter performance
Ducted versus ductless
A ducted system uses your existing duct network if it can carry the airflow. A ductless system puts a head in each zone and suits additions, converted spaces and homes without ducts.
Hybrid with a furnace
The heat pump handles heating in milder weather, and the furnace takes over when it gets cold enough, based on thermostat settings. This suits a home whose furnace still has useful life. Our heat pump selection guide compares the options.
Cold-climate performance
Capacity and efficiency fall as outdoor temperatures drop, and by how much depends on the model. We use the manufacturer data for low temperatures instead of a single headline number, and size backup heat to match.
Electrical requirements
Most installs need a dedicated circuit, and some homes need panel work first. We check the available capacity early. Panel work is covered under electrical panel and circuits.
Rebates are conditional
Eligible Ontario customers may qualify for up to $7,500 depending on the program rules, equipment, property and funding available at the time. These are Ontario programs only, and approval is not automatic. Review rebate eligibility and the rebate basics before you order equipment.
Ontario notes
Heat pumps in Ontario: climate, rates and rules
Cold-climate performance and backup
Heat pump capacity falls as outdoor temperatures drop, and by how much depends on the model. Ontario winters include stretches of deep cold, so backup heat is part of the design. That might be an existing furnace, electric elements or another source, with changeover set at the thermostat.
Electricity and gas rates
Whether a heat pump costs more or less to run than gas depends on your electricity plan, your gas rate and how the system performs at each outdoor temperature. Time-of-use plans can change the answer. Rates change over time, so compare using your own bills rather than a headline number.
Rebates change over time
Ontario heat pump programs depend on the rules, the equipment, the property and the funding available at the time. Eligibility, required steps and paperwork can change. Check current conditions before you order equipment. See rebate basics for how to approach it.
Permits, bylaws and condo rules
Permit requirements for heat pumps differ by municipality, and electrical work may need its own permit. Bylaws can affect where an outdoor unit goes, and condo or townhouse rules can add approval steps. We confirm what applies to your property before the install is booked.

Customer reviews
What customers say
These guys were amazing. they installed 2 panasonic heatpump units for us. They were very fast and professional. Their prices very very good too. would definitely recommend them.
Had a great experience with Kelvin Mechanical. They installed my heat pump and furnace in the same day, and I was seriously impressed with how efficient and professional the whole process was. Their pricing was way better than other quotes I got, and the quality of work exceeded expectations. The team showed up on time, looked professional, and worked like a well-coordinated crew. Zia did an excellent job leading the team — super knowledgeable and made sure everything was done right. I'd definitely recommend them if you're looking for solid HVAC work at a great price.
They installed my my heat pump and a furnace. The prices were really fair. Would definitely recommend

Questions about Heat Pump Installation
Will a heat pump keep my Ontario home warm in January?
Cold-climate models are designed for low outdoor temperatures, but performance depends on the model and the conditions. Many homes add a furnace or electric backup for the coldest days. We plan backup heat as part of the design, not as an afterthought.
Should I choose a ducted or a ductless heat pump?
If your ducts are in decent shape and sized for the airflow, a ducted system keeps your existing layout. Ductless suits additions, rooms with weak airflow and homes without ducts. The site review sorts it out.
Can I keep my furnace?
Yes. A hybrid setup keeps the furnace as backup heat, with controls deciding which source runs. Whether it makes sense depends on the furnace age, the ductwork and your energy rates.
Do I qualify for the Ontario heat pump rebate?
Eligible Ontario customers may qualify for up to $7,500 depending on the program rules, equipment, property and funding available at the time. Check rebate eligibility before ordering. We cannot promise approval.
How much does a heat pump installation cost?
Pricing varies with equipment, electrical work, ductwork, installation complexity and warranty options; a quote follows a site review. Financing options may be available, subject to provider approval, terms and expiry.
What size heat pump does a 2,000 sq ft house need in Ontario?
There is no fixed answer. Two homes of the same floor area can have very different heat loss depending on insulation, windows, air leakage and layout. Heating load usually sets the size in Ontario, and cooling load is checked too. We use a load calculation and the model's low-temperature data, not a square-foot rule.
What is a balance point, and why does it matter for my heat pump?
The balance point is the outdoor temperature where the heat pump's output matches your home's heat loss. Below it, backup heat has to supply the rest. The changeover or lockout temperature set in the thermostat is usually based on it, and it matters most for hybrid systems. Cold-climate models can lower the balance point, but it varies by model.
Do I need to apply for the heat pump rebate before installation?
Yes, for the Home Renovation Savings Program: it states that pre-approval is mandatory and that installations done before approval are not eligible, so check the order of steps before you order. Eligible Ontario customers may qualify for up to $7,500 on qualifying heat pump equipment, depending on the program rules, equipment, property and funding available at the time. We help review conditions before you commit.
Will my electrical panel handle a heat pump?
It depends on the service size and your other loads. Many homes built between the 1950s and 1990s have smaller services. A heat pump needs a dedicated circuit, and electric backup elements add to the load. An electrical professional reviews capacity. See electrical panel and circuits.
Is a heat pump cheaper to run than a gas furnace in Ontario?
It depends on your natural gas and electricity rates, your electricity plan, the heat pump's performance at the outdoor temperature and your home. There is no single answer. We can compare options using your own bills, and we do not promise a specific saving.
Where should the outdoor heat pump go to handle snow?
The unit should sit on a raised stand or wall bracket above the snow line, clear of roof drip and snow slides, with room for airflow and service. Defrost water needs to drain away from walkways, where it can turn to ice. Bylaws and neighbours' windows also matter for placement.
Does a heat pump work during a power outage?
No, a heat pump needs electricity to run. Most gas furnaces also need power for the blower and controls. If outages are a worry, ask about backup power options. A generator is a separate project and needs correct sizing and safe installation by qualified professionals.
What is a cold-climate heat pump?
It is a heat pump designed to keep useful output at lower outdoor temperatures, with performance published in the manufacturer's low-temperature data. The ratings vary by model, so check the table for your lowest design temperature. Many Ontario homes still add backup heat for the coldest days.
How long does a heat pump last in Ontario?
Many heat pumps are designed to last around 15 years or longer when they are installed correctly and serviced, but real life varies with the model, installation quality, climate and upkeep. Ontario outdoor units face winter ice and snow as well as summer heat, so keeping the coil and fan clear and booking regular service helps. Ask about warranty terms before you buy.
Do I need professional installers for a new heat pump?
Yes. Heat pump installation involves refrigerant work, electrical connections and airflow design. For an Ontario Home Renovation Savings rebate the contractor must also be registered and listed by the program before you proceed. Electrical work needs a licensed electrical contractor and the required permit or notification. See electrical panel and circuits.
