If your furnace is getting older, becoming less reliable, or costing more to run every winter, you’ve probably started wondering whether now is the time to replace it – and whether a heat pump makes sense as the alternative. It’s a decision more BC homeowners are making, and for good reason. Replacing a furnace with a heat pump can mean lower energy bills, year-round comfort from a single system, and access to significant government incentives that bring the upfront cost down considerably. This guide walks you through the key questions to help you decide. If you’re ready to explore your options, Foster’s heat pump services are a good place to start.
Signs Your Furnace Is Ready to Be Replaced
Not every furnace that’s showing its age needs to go immediately – but there are signals worth taking seriously.
Age. Most gas furnaces last between 20 and 30 years with regular maintenance. If yours is approaching or past that range, it’s operating on borrowed time. Replacing it on your terms – before a breakdown – gives you the time to make a considered decision rather than an emergency one.
Frequent repairs. An occasional repair is normal. If you’re calling for service repeatedly, or facing the same recurring issue, the cost of keeping an old system running can quickly approach what a new one would cost – without the efficiency and reliability that comes with it.
Rising energy bills. Furnaces lose efficiency as they age. If your heating bills are climbing but your usage hasn’t changed, your furnace is likely working harder than it should to produce the same amount of heat.
Inconsistent comfort. A furnace that struggles to maintain temperature, produces uneven heat across rooms, or runs constantly without hitting the set point is telling you something. These are signs of a system under real strain.
A repair bill that doesn’t make sense. A useful rule of thumb: if the cost of a repair exceeds roughly 50 percent of the cost of a new system, and the furnace is already past the 15-year mark, replacement is almost always the better financial decision.
Why Replace a Furnace with a Heat Pump?
A heat pump doesn’t just replace one function – it replaces two. Where a furnace only heats, a heat pump both heats and cools your home from a single system. That means no separate air conditioner, no juggling two sets of maintenance, and no compromise on comfort in warmer months.
Beyond that, heat pumps are significantly more efficient than gas furnaces. Rather than burning fuel to generate heat, a heat pump moves heat from one place to another – which allows it to deliver two to three times more heat energy than the electricity it consumes. That efficiency gap translates directly into lower monthly energy bills over the life of the system.
According to Natural Resources Canada, heat pumps are among the most efficient heating technologies available for Canadian homes – and modern cold-climate models are designed to perform reliably even when temperatures drop well below freezing.
For homes currently on electric baseboard heating, the savings from switching to a heat pump are often dramatic. For homes replacing a gas furnace, the comparison is more nuanced – but when rebates and long-term operating costs are factored in, a heat pump frequently comes out ahead.
The Rebate Case: Why Now Is a Good Time to Act
This is where the decision gets more compelling. BC homeowners who qualify for available incentive programs can currently access up to $16,000 in government rebates on eligible heat pump installations. That figure represents the stacked total of provincial and federal programs – and it can bring the net cost of a heat pump installation into genuinely competitive territory with a furnace replacement.
Rebate programs are funded and subject to change. Eligibility, amounts, and program availability shift over time, and there’s no guarantee that current incentives will remain at their current levels. Homeowners who are already thinking about replacing their furnace before winter are in a strong position to act while the programs are fully funded.
The timing matters practically too. Booking a heat pump installation in the shoulder season – before the heating demand of winter kicks in – typically means faster scheduling and more flexibility in the installation timeline. Waiting until your furnace fails in December means less choice and more urgency.
What to Consider Before You Replace Your Furnace with a Heat Pump
A heat pump is the right move for most homeowners replacing an older furnace – but a few practical questions are worth working through first.
Does your home have ductwork? If your home already has ducts in reasonable condition, a ducted heat pump is a natural fit and installation is relatively straightforward. Homes without ductwork are better suited to a ductless mini-split system, which delivers heating and cooling to each room without ducts. Both options are effective – the right choice depends on what’s already in place.
What is your home’s electrical setup? Some older homes need an electrical panel upgrade to support a heat pump. This is worth confirming before installation so it can be factored into the budget upfront rather than arriving as a surprise.
How cold does it get where you live? Modern cold-climate heat pumps are built to handle temperatures well below freezing. For most of BC – and Vancouver Island in particular – a quality heat pump handles the full heating season without supplemental heat. A technician can advise on the right system for your climate conditions.
What rebates do you qualify for? Eligibility depends on your current heating source, the equipment you’re installing, and which programs are active at the time of installation. An experienced installer will know how to structure the project to maximize your total incentive.
Choosing the Right Heat Pump for a Furnace Replacement
Not all heat pumps are the same, and the right system matters as much as the decision to switch.
Mitsubishi Electric heat pumps are Foster’s recommended system for most furnace replacements. Their Hyper-Heating INVERTER technology allows the system to deliver consistent heat down to -13°F (-25°C) – eliminating the need for a supplemental heat source in virtually all BC conditions. Combined with industry-leading efficiency ratings and whisper-quiet operation, a Mitsubishi heat pump is a system built to perform for decades.
The installation itself matters too. A properly sized and professionally installed system performs as designed from day one. An undersized system will struggle in cold weather; an oversized one will short-cycle and wear out faster. Getting the sizing right is a technical assessment, not a guess.
What Happens to Your Existing Ductwork?
If your furnace replacement involves a ducted heat pump, your existing ductwork can typically be reused – provided it’s in reasonable condition. A technician will assess the duct system and flag anything that needs attention before the new system goes in. In many cases, existing ducts are perfectly serviceable and the transition is straightforward.
If ducts need repairs or modifications, that work is factored into the installation scope. Your installer should be transparent about what’s included in the quote and what might affect the final cost.
Making the Decision
Should you replace your furnace with a heat pump? For most homeowners whose furnace is aging, requiring frequent repairs, or simply falling short on comfort, the answer is yes. The efficiency advantages are real, the rebate opportunity is significant, and the timing – ahead of winter, while programs are funded – makes acting sooner rather than later a financially sound decision.

Frequently Asked Questions
Is it worth replacing a furnace with a heat pump?
For most homeowners, yes – particularly if the furnace is aging, requiring frequent repairs, or running inefficiently. A heat pump replaces both heating and cooling from a single system, operates more efficiently than a gas furnace, and currently qualifies for significant BC rebate programs that reduce the upfront cost.
How much does it cost to replace a furnace with a heat pump in BC?
Costs vary depending on the system type, home size, and installation complexity. Before rebates, a quality heat pump installation typically ranges from $5,000 to $15,000 or more. With available government incentives, eligible homeowners can receive up to $16,000 back – which can significantly change the net cost picture.
Can a heat pump replace a gas furnace entirely?
In most BC climates, yes. Modern cold-climate heat pumps are engineered to deliver heat effectively even when outdoor temperatures drop well below freezing. For most Vancouver Island homeowners, a heat pump handles the full heating season without supplemental heating.
What happens to my ductwork if I switch to a heat pump?
If your home already has ductwork in good condition, it can typically be used with a ducted heat pump. A technician will inspect the ducts and advise on anything that needs attention before installation. Homes without ductwork are well-served by ductless mini-split systems.
When is the best time to replace a furnace with a heat pump?
Ideally before it fails – and before the peak of winter, when demand for HVAC technicians is highest. Replacing your furnace in the shoulder season gives you more scheduling flexibility and time to make a considered decision. It also allows you to take full advantage of current rebate programs before they change.
