Walk any Burlington street in January and you’ll see the story on the rooftops. Some homes breathe steam from high‑efficiency gas furnaces. Others hum quietly behind their siding as cold‑climate heat pumps churn out steady warmth. The choice between a heat pump and a furnace is no longer a binary debate about efficiency on paper. It’s about how your house actually feels in a lake‑effect cold snap, what you pay each month with Ontario’s gas and electricity rates, and how your equipment fits the realities of Burlington’s housing stock, from 1970s two‑storeys in Headon Forest to newer infills near Aldershot.
I’ve sized and installed both systems across Halton and the western GTA. What follows is a practical way to decide what’s right for your home, with clear numbers, weather context, and pitfalls to avoid. We will zoom in on Burlington, but the logic holds across the region. Many readers from Oakville, Hamilton, Mississauga, and even as far as Kitchener or Guelph face similar trade‑offs when comparing the best HVAC systems for their street, their budget, and their tolerance for drafty rooms.
Burlington’s climate sets the rules
A good decision starts with the design temperature. Burlington sits on the west edge of Lake Ontario, which moderates shoulder seasons but does not spare us from arctic air. The heating design temperature used by local engineers typically falls around minus 18 to minus 21 Celsius. We do not live at minus 21 all winter, yet equipment should handle that point without collapsing.

Heat pumps have changed dramatically in the last five to seven years. Cold‑climate units from major brands can still deliver useful heat at minus 25, sometimes lower. Output tapers as temperatures drop, so choosing the right capacity matters. In practical terms, a well‑sized cold‑climate heat pump in Burlington can carry the house for 85 to 95 percent of the season’s hours on its own. You can cover the remaining coldest hours with a small electric backup, a dual‑fuel gas furnace, or simply by setting the thermostat 1 degree lower on extreme nights. A conventional gas furnace, by contrast, shrugs at cold snaps and delivers full output whenever called.
Humidity also plays a role. Burlington winters are dry indoors, yet fall and spring can be damp. Heat pumps, with their longer, lower‑temperature cycles, tend to smooth indoor humidity swings and avoid the hot‑cold blasts you feel with oversized furnaces.
Cost to run: gas versus electricity under Ontario rates
This is the part most homeowners ask about first. Without grounding in local rates, comparisons get fuzzy. As of late 2024, natural gas in Ontario for residential users often lands around 10 to 14 cents per cubic metre for the commodity, but your bill includes delivery, carbon charges, and fixed fees. When all in, many households effectively pay roughly 35 to 50 cents per cubic metre. One cubic metre of gas has about 10.55 kWh of energy. A 95 percent efficient furnace turns that into approximately 10 kWh of heat for every cubic metre burned, so your effective cost per kWh of delivered heat often falls near 3.5 to 5 cents.
Electricity under the Ontario Electricity Rebate and time‑of‑use tiers ranges widely across the day, but off‑peak rates are typically around 8 to 10 cents per kWh, mid‑peak around 11 to 15, and on‑peak around 16 to 20, before fees. Delivery, regulatory, and fixed charges bring real‑world costs closer to 15 to 25 cents per kWh for many households on an annualized basis. A heat pump doesn’t convert electricity to heat the way baseboards do, it moves heat. Its performance is measured by COP, the coefficient of performance. A COP of 3 means one kWh of electricity yields 3 kWh of heat. Modern cold‑climate heat pumps in Burlington will often run between 2.5 and 4 COP in milder weather, and between 1.5 and 2.5 in deep cold.
Do the math, and you’ll see why outcomes vary:
- If your blended electricity cost is 18 cents per kWh and your heat pump averages a seasonal COP of 2.8, you pay about 6.4 cents per kWh of delivered heat. That’s higher than gas at 4 to 5 cents, but the gap narrows if your home has above‑average gas delivery fees or you use more off‑peak power for heat pump operation. If your home uses a dual‑fuel setup that lets the heat pump handle shoulder seasons at COPs above 3.5, then switches to gas only for the coldest 15 percent of hours, the annual cost can match or beat a gas‑only furnace, particularly in well‑insulated homes.
I’ve audited Burlington homes where a heat pump saved 10 to 25 percent over a furnace. I’ve also seen the opposite when the unit was undersized or paired with poor ducts. Local electricity pricing, how you schedule your thermostat, and your building envelope tilt the economics. The cleanest strategy is to model both options with your house’s heat loss and actual rates, then check sensitivity to rate changes.
Upfront installation costs and what they really include
On paper, a standalone high‑efficiency gas furnace in Burlington might run between 4,500 and 8,500 dollars installed, depending on brand, modulation, and duct complexity. A cold‑climate heat pump for a typical detached home often lands between 10,000 and 18,000 dollars when set up as a full ducted system. If you keep a furnace as backup in a dual‑fuel configuration, add 2,000 to 4,000 dollars to https://devinulev142.raidersfanteamshop.com/spray-foam-insulation-guide-for-hamilton-garage-and-rim-joist-uses integrate controls and ensure proper sizing. Ductless multi‑splits for homes without ducts can range from 8,000 to 20,000 depending on zones. Prices vary by contractor, rebates, electrical upgrades, and whether you need new line sets or pads.
It is tempting to compare sticker prices only. In practice, HVAC installation cost in Burlington and the wider GTA should account for:
- Load calculations and duct static pressure testing rather than square‑foot rules. Electrical work for heat pumps, which can mean a new 240 V circuit, a disconnect, or panel upgrades if you also plan an EV charger or induction range. Condensate management, defrost routing, and cold weather clearances for outdoor units to prevent snow recirculation. Smart dual‑fuel controls if you keep gas for backup, with a lockout temperature tuned to local economics. Commissioning time, including refrigerant charge verification by weight and superheat/subcooling, not guesswork.
Contractor skill and time here are not luxuries. They are the difference between a system that sings and one that burns money. Across Burlington, Oakville, Mississauga, and Hamilton, the best HVAC systems are rarely the ones with the shiniest brochures. They are the ones installed by techs who measure.

Comfort: steady warmth versus big blasts
Gas furnaces deliver hot supply air, often 45 to 55 degrees Celsius at the register. The room warms quickly, then the unit shuts off, and you coast until the next call. If the furnace is oversized, the cycles get short and frequent. The house feels a bit like stop‑and‑go traffic. A fully modulating furnace softens that pattern, but the supply temperatures are still high relative to room temperature.
Ducted heat pumps run longer at lower supply temperatures, typically 30 to 40 degrees at the register in mild weather and higher in colder weather as the compressor ramps. The heat feels gentler. Rooms stay within a tighter temperature band because the system does not stop and start as often. Cold corners benefit from the constant air movement. Some people love this and say their home finally feels even. Others miss the toasty blast at the register. It’s a preference, but I find most households adapt quickly, especially when we tune fan speeds and set realistic thermostat expectations.
Noise is another comfort dimension. Modern inverter heat pumps can be very quiet outdoors, 50 to 58 dB at one metre for many models on lower speeds. On full tilt during defrost in minus 18 wind, you will hear them, but it is a steady hum rather than the whine older units had. If you have a small lot in Burlington or Oakville with tight side setbacks, choose a model with a documented sound profile and place it carefully. Furnaces are quiet indoors when properly installed with lined plenums and flexible connectors.
Reliability in real cold and the defrost question
Heat pumps have two winter quirks. First, as the outdoor coil gathers frost, the unit flips into defrost mode, briefly reversing to melt the ice. Supply air can feel neutral or cool for a few minutes. Properly set defrost controls and thermostats minimize comfort swings. Second, output declines with temperature, so a heat pump that matches your house at minus 10 may fall short at minus 20. Plan for these periods. Dual‑fuel setups switch to gas below a chosen temperature, for example minus 8 or minus 12. All‑electric setups can pair with an auxiliary electric heater in the air handler. If sized correctly and if your insulation is decent, the aux heat should run only during limited hours per season.
Gas furnaces handle cold snaps without drama. They bring their own risks, mainly combustion safety and venting. Modern sealed combustion units are safe, but annual checks catch cracked heat exchangers, failed inducer motors, and blocked PVC vents. When storms slam Burlington, both systems ultimately depend on electricity for control boards and blowers, so a small generator or battery helps either way.
House first, equipment second
Before you pick a system, know your house. Two properties on the same street can have very different heat loads. A 1998 build with R‑50 attic insulation, tight windows, and sealed rim joists will behave differently from a 1972 split‑level with original sliders, leaky returns, and R‑20 in the attic.
The cheapest heating dollar is the one you do not need. Modest envelope upgrades change the economics of heat pump vs furnace:
- Attic insulation from R‑22 to R‑50 in Burlington homes typically costs 1,500 to 3,500 dollars, depending on square footage and baffle work. The attic insulation cost in Oakville or Hamilton is similar, and the payback is quick. Blown cellulose or fiberglass works well. Spray foam is for specific air sealing or cathedral ceilings, not for most open attics. Air sealing around top plates, rim joists, and returns cuts drafts. These are labour‑heavy but inexpensive materials jobs with outsized comfort gains. If you are renovating, consider exterior foam or dense‑pack cellulose in walls. Wall insulation benefits show up as even temperatures and smaller equipment.
Why does this matter for your choice? Because every reduction in heat loss drops the peak BTUs you need. A smaller peak means your heat pump can carry deeper into winter without backup, or your furnace can be sized smaller with longer, quieter cycles. It also lowers your HVAC installation cost by keeping duct sizes and equipment models in a more common range. For homeowners comparing the best insulation types in Burlington, Kitchener, or Toronto, the right call is normally blown attic insulation plus targeted air sealing first. Spray foam has its place, as a spray foam insulation guide would explain, but it is often not the first dollar to spend in a typical detached home.
Ducts decide more than you think
I carry a manometer more often than a tape measure. Static pressure tells you whether your ducts can deliver the air your equipment wants to move. Heat pumps push larger volumes of slightly cooler air. If your ducts were sized for a high‑temperature furnace and have a lot of undersized branches, reducing friction becomes a priority. I’ve had projects in Burlington where a simple return upgrade, a handful of radius elbows, and a balancing damper turned a mediocre heat pump install into a quiet, even system. Oversized equipment installed on high static pressure ductwork masks the problem with brute force and noise. Resist that temptation.
For ductless systems in townhouses or older bungalows, indoor head placement is critical. A single wall‑mounted unit in the living room will not heat bedrooms well with doors closed on a minus 15 night. Multizone systems help, but each zone adds cost and complexity. This is where hybrid approaches shine: a ducted heat pump for the main space with a small ductless head in a stubborn addition, or a gas furnace paired with a heat pump coil for primary heat while the furnace handles extreme nights.
Rebates, carbon pricing, and the longer view
Programs change frequently, so I avoid quoting exact rebate dollars here. Burlington homeowners have seen incentives for heat pumps, weatherization, and smart thermostats under federal and provincial programs, and local utilities sometimes layer on modest bill credits. When available, they can carve thousands from a project, particularly for all‑electric heat pumps in primary residences. Carbon charges on natural gas have risen gradually, and while gas remains relatively inexpensive per unit of heat today, policy signals point to continued pressure on its price over the next decade. That matters if you plan to stay in your home long enough to see two full equipment lifecycles.
For homeowners also contemplating solar PV, a heat pump moves more of your heating to electricity, which you can offset with rooftop generation at least in shoulder seasons. I have clients in Burlington and Guelph who pre‑wired for PV and a heat pump during a major renovation, then added panels later. Their winter bills still include grid power, but their spring and fall heating is effectively solar‑assisted.
Real‑world scenarios from Burlington streets
Maple area, 1980s two‑storey, 2,200 square feet, average insulation. The owners wanted lower carbon and steadier heat. We installed a 3‑ton cold‑climate heat pump with a 10 kW electric backup and sealed the attic to R‑50. Ducts were borderline, so we added a second return and swapped a few tight elbows. Their electricity usage rose about 4,800 kWh for the heating season, but gas usage dropped to nearly zero. With time‑of‑use optimization and preheating in off‑peak hours, their annual heating cost fell about 15 percent compared to their previous 80 percent furnace. Comfort improved, especially in the over‑garage bedroom.
Headon Forest bungalow, 1,400 square feet, 1969, older windows. The owner wanted the lowest possible upfront cost with reliable warmth. We put in a two‑stage, high‑efficiency gas furnace and a smart thermostat. We also blew in attic insulation and sealed the attic hatch, a modest extra that allowed us to downsize the furnace. Bills stayed predictable, the house got quieter, and they plan to add a heat pump coil at the next AC replacement.
Aldershot semi, 1,650 square feet, narrow lot, noise‑sensitive neighbors. The homeowner leaned toward a heat pump but worried about outdoor sound. We chose a unit with a proven quiet rating and installed it on the driveway side behind a louvered screen, set on anti‑vibration feet. Sound at the property line measured in the low 40s dB at night under typical operation. With a gas line already there, we set it up dual‑fuel to lock out gas above minus 10. Their shoulder season runs almost entirely on the heat pump, and the furnace carries cold snaps.
These cases are not prescriptions, they are examples of how nuance drives decisions. The best HVAC systems in Burlington and neighboring cities like Oakville, Hamilton, Mississauga, and Toronto share a pattern: the equipment matches the house, the ducts allow airflow, and the installer commissions the system with instruments, not guesswork.
Maintenance: avoid breakdowns and keep performance high
Both systems are reliable when maintained. A simple HVAC maintenance guide applies:
- Replace or wash filters regularly. In heat pump homes, airflow is king. Restrictive 1‑inch pleated filters clog quickly. Consider deeper media filters if your return can take them. Keep the outdoor unit clear. In winter, shovel snow away from the heat pump, maintain 18 to 24 inches of clearance, and make sure downspouts do not discharge onto the coil. Ice buildup is not a maintenance badge, it is a performance killer. Schedule annual service. For furnaces, this means combustion safety checks, heat exchanger inspections, and venting verification. For heat pumps, a check of refrigerant charge, defrost operation, and coil cleanliness. I prefer a fall visit for heat pumps to catch defrost issues before the first freeze. Watch your static pressure. Ask your tech to measure it. If it is persistently high, fix the ducts rather than living with noise and reduced capacity. Use your thermostat wisely. Avoid big nightly setbacks with heat pumps in deep winter, as recovery can trigger auxiliary heat. Gentle schedules and off‑peak preheating work better.
Those steps prevent most no‑heat calls. They also keep your seasonal efficiency high. A heat pump with a dirty outdoor coil or a furnace with a clogged filter can lose 10 to 20 percent of performance long before anything fails outright.
When a furnace still makes the most sense
There are homes where a gas furnace is the straightforward choice. If your electricity service is already maxed with a hot tub, EV charger, and induction range, a heat pump may require a costly panel upgrade. If your ducts cannot be economically improved and you want high supply temperatures to overcome poor distribution, a modulating furnace helps. If you plan to move in two years and care primarily about minimum upfront HVAC installation cost in Burlington or Hamilton, a well‑installed furnace meets the brief. The furnace path is simpler, and in Ontario’s current rate environment, it remains cost effective.
When a heat pump is the better call
If you value steady comfort, lower carbon, and you are willing to tune your home’s envelope a bit, a cold‑climate heat pump pays off. This is especially true in houses with decent insulation and reasonable ducts, or where you are replacing both a furnace and an aging air conditioner anyway. One outdoor unit that heats and cools with inverter control simplifies your system and often quiets the home. Homeowners in Burlington, Oakville, and even Toronto’s older neighborhoods have been surprised by how comfortable a right‑sized heat pump feels in February once we dial in fan speeds and balance registers.
For larger homes or rural edges where gas is not available or propane is expensive, all‑electric heat pumps paired with good air sealing are the obvious choice. The energy efficient HVAC conversation in Cambridge, Guelph, Kitchener, and Waterloo often starts there, since some pockets lack natural gas service.
Sizing and selection: the short version
Because list limits help clarity, here is a focused selection checklist for Burlington conditions:
- Get a real heat loss calculation using at least CSA F280 or Manual J equivalent, with window areas, insulation levels, and air leakage considered. Target a heat pump that meets 90 to 100 percent of your design load at minus 8 to minus 12, knowing it will carry most hours and use backup in rare extremes. For dual‑fuel, set a lockout temperature based on your gas and electricity rates. Revisit this annually if rates shift. Fix duct bottlenecks before or during installation. If total external static pressure exceeds manufacturer limits at design airflow, address it. If replacing AC and furnace together, price the heat pump delta. The incremental cost is often smaller than you expect, especially with available incentives.
Follow those steps and you align equipment to Burlington’s climate, your utility rates, and your comfort goals.
A note on insulation types and R values
Homeowners researching energy efficient HVAC in Burlington often stumble into insulation debates. It is worth a brief pass. R value explained simply: it measures resistance to heat flow. Higher R means slower heat loss. Attic insulation upgrades are the lowest friction work. Blown fiberglass and cellulose are both proven. Cellulose tends to reduce air movement within the insulation slightly better, fiberglass does not settle as much. Both need proper baffles and air sealing to perform to their rated R. Spray foam shines when you need combined insulation and air sealing in difficult cavities, rim joists, or cathedral ceilings. It is not mandatory for most attics. In walls, dense‑pack cellulose and exterior foam retrofits can be transformative during siding projects, but they are larger investments.
Reduce load first, then pick equipment. That order yields smaller, quieter systems and better odds that a heat pump will carry your home most of the winter.
Region‑wide perspective
Across the GTA and the 401 corridor, I see similar patterns. In Mississauga and Oakville, lot sizes and noise bylaws push us to quieter outdoor units and careful placement. In Hamilton, older brick homes often need duct tweaks or a hybrid approach. In Kitchener, Waterloo, Cambridge, and Guelph, many clients chase energy efficient HVAC with a blend of weatherization and right‑sized heat pumps, especially where new tech incentives have traction. Toronto’s semi‑detached stock benefits from slim ducted heat pumps that fit tight mechanical rooms.
You will see pages touting the best HVAC systems in Burlington, Brampton, Toronto, and beyond. The best is the one mapped to your load, ducts, and lifestyle, installed by people who measure and who will answer the phone in a storm.
The bottom line for Burlington homeowners
If you value lowest upfront cost and zero fuss during cold snaps, a high‑efficiency gas furnace remains a solid, familiar option. If you prioritize steady comfort, reduced emissions, and long‑term operating flexibility, a cold‑climate heat pump, ideally with some envelope upgrades, deserves a hard look. Many Burlington homes end up with a smart dual‑fuel setup that leans on the heat pump for most hours and lets the furnace handle the few bitter nights each year. That approach splits the difference on cost, comfort, and climate readiness.
Whichever path you choose, insist on a load calculation, static pressure measurement, and a commissioning report. Ask the contractor to show you airflow numbers, not just model numbers. That single habit prevents more problems than any brand decision ever will.
