Heat Pump
Choosing the Right Heat Pump for Your Fraser Valley Home in 2026
Cohesive Mechanical
May 1, 2026
Once you’ve decided a heat pump is the right move, the next decision is which configuration fits your home. There are three main types - ducted, ductless mini-split, and dual-fuel. Each is the right answer for different homes.
The wrong system, even from a great brand, won’t perform. The right system, properly sized and cleanly installed, runs quietly in the background for 12–15 years.
The three main types of heat pumps
Ducted heat pump
A ducted heat pump uses your home’s existing ductwork - the same registers a furnace would use - to distribute heated and cooled air. The outdoor unit handles the refrigerant cycle; an indoor air handler (often replacing your old furnace location) pushes conditioned air through the ducts.
Best fit for: - Homes with existing ductwork in good condition - Whole-home heating and cooling from one system - Homeowners replacing a gas or oil furnace and wanting a clean swap
Pros: Single system handles every room. Familiar thermostat control. Lowest equipment cost relative to capacity. Hidden - no wall units visible.
Cons: Limited zoning (the whole house is on one thermostat by default; multi-zone retrofits add cost). Existing ducts need to be in reasonable shape. Some homes need duct upgrades to handle heat pump airflow correctly.
Ductless mini-split
A ductless mini-split uses an outdoor unit connected to one or more indoor wall-mounted (or ceiling cassette) heads. No ductwork needed - just a small refrigerant line and a power feed running from outside to each indoor head.
Best fit for: - Homes with no ductwork (older houses, baseboard-heated homes) - Additions, basements, garages, suites, or single-room cooling needs - Multi-zone setups where different rooms run at different temperatures
Pros: No ductwork required. True zoning - each indoor head runs independently. Highest seasonal efficiency of the three configurations. Quiet. Easier to install in awkward house layouts.
Cons: Wall heads are visible (some owners care, some don’t). Higher per-zone cost - a 4-zone system costs more than a single-zone ducted setup. Requires careful head placement for even comfort.
Dual-fuel
A dual-fuel system pairs a new heat pump with an existing (or new) gas furnace. The heat pump runs as the primary heating system. When outdoor temperatures drop below a threshold you set, the furnace takes over.
Best fit for: - Homes that already have a working gas furnace - Homeowners who want maximum efficiency in mild weather and gas-furnace headroom for cold snaps - Whole-home applications where redundancy matters
Pros: Heat pump efficiency for 90%+ of the Fraser Valley heating season. Furnace as backup for the rare cold snap or a power-grid issue. Existing furnace gets used rather than retired.
Cons: Highest up-front cost (you’re keeping or installing two systems). More complex controls - but a modern smart thermostat handles the switching automatically.
Sizing - why bigger isn’t better
Heat pump sizing is the single most common place installs go wrong. An oversized system short-cycles, doesn’t dehumidify properly in summer, and never reaches steady-state efficiency. An undersized system runs constantly in winter and falls behind on cold days.
Proper sizing comes from a Manual J load calculation - heat-loss math that factors in:
Square footage and ceiling height
Insulation level (walls, attic, floor)
Window count, size, and orientation
Air sealing quality
Number of occupants
Ductwork condition (for ducted systems)
Local climate data - for us, Fraser Valley winter design temps
The output is a heating and cooling load expressed in BTU/hour. We match equipment capacity to that number, not to the square footage alone.
This is what the Home Energy Assessment delivers. There’s no “we always install the same model” - if the math says you need a 2-ton unit, we install a 2-ton unit, even if it’s smaller (and cheaper) than what your neighbor has.
Single-zone vs. multi-zone - for ductless setups
If you’re going ductless, you’ll choose between a single-zone mini-split (one outdoor unit, one indoor head) or a multi-zone system (one outdoor unit, multiple indoor heads).
Single-zone: simplest, cheapest per zone. Best for one-room cooling, single-area additions, or smaller homes where one head can serve a main living space.
Multi-zone (2–8 indoor heads): allows different temperatures in different rooms - for example, cooler bedroom at night, warmer main floor during the day. Higher upfront cost, but much better whole-home comfort if the home’s layout has different heat needs across rooms.
For a typical Fraser Valley home that’s mostly open-plan downstairs with bedrooms upstairs, a 3- or 4-head multi-zone often fits well: one head for the main floor, individual heads for the primary bedroom and one or two other key rooms.
Brand and equipment - what matters and what doesn’t
ENERGY STAR® certification is the basic floor - a standard requirement for rebate eligibility. Beyond that, several major manufacturers (Mitsubishi, Daikin, Lennox, Carrier, Trane, and others) make excellent cold-climate heat pumps. They have different price points, slightly different feature sets, and different warranty structures.
Brand matters less than installer skill.
A great unit installed badly performs worse than a mid-tier unit installed correctly. The most common failure modes are:
Refrigerant charge wrong on commissioning
Indoor unit airflow undersized or unbalanced
Outdoor unit placed too close to a wall or in poor airflow
Line set length too long, sized wrong, or not insulated properly
Electrical connections undersized for the unit
These are install-quality issues, not brand issues. We choose the brand and model based on what fits the home and the rebate program - and we install it properly.
What to ask a heat pump installer
A 10-question checklist before you sign:
Are you HPSC-registered? Required for most BC rebates. If not, you’ll lose rebate eligibility.
Is there a licensed gas fitter on staff? Necessary if you’re considering dual-fuel or have any gas work.
What manufacturer training do your techs have? Manufacturer-certified installers handle equipment correctly and protect the warranty.
What sizing methodology do you use? Should be Manual J load calculation, not a square-footage rule of thumb.
Will you check my electrical panel before quoting? Should be yes. If they don’t, panel surprises during install are common.
Who pulls the permits? The installer should. Self-permitting customer-side is a red flag.
What’s your warranty - equipment and labor? Equipment warranty is the manufacturer’s. Labor warranty is the installer’s. Get both in writing.
Can you walk me through three recent comparable installs? Reference checks aren’t paranoid - they’re standard for any major home upgrade.
What’s your post-install support look like? Annual service plans, response time for issues, warranty service approach.
What does your clean-up and finish standard look like? Cohesive’s brand line is “clean installs” for a reason - the difference between a tidy mechanical room and a chaotic one shows up over the next 15 years.
Red flags to walk away from
Quotes given over the phone without a home visit
No load calculation - pricing based on square footage alone
Pressure to sign today for “limited-time” pricing
No HPSC registration when rebates are part of the deal
No clear permit plan
Cash-only or no formal contract
Significantly cheaper than competing quotes - heat pump installs have a real cost floor; “30% under everyone else” usually means corner-cutting somewhere

FAQ
How long does a heat pump installation take?
Most Fraser Valley installs run 1–2 days on site. Day one is typically removal of the old equipment, mounting the outdoor unit, running line sets, and electrical work. Day two is indoor unit install, refrigerant charging, commissioning, and walkthrough. More complex installs (multi-zone ductless, dual-fuel, panel upgrades) can take longer.
Are permits required for heat pump installation in BC?
Yes - electrical permits are required for the new circuit, and gas permits if any gas work is involved. Some municipalities also require mechanical permits. Cohesive handles all permitting as part of the install. If an installer asks you to pull permits yourself, that’s a red flag.
What if my electrical panel is too small for a heat pump?
Older homes with 100A service sometimes need a panel upgrade or a load-management device to add a heat pump. We check panel capacity during the Home Energy Assessment, before pricing - so a panel upgrade either gets quoted up front or we recommend a load-management approach that avoids it.
Is my home a good candidate for a ductless mini-split?
Homes without existing ductwork, homes with awkward layouts, additions, basements, suites, and single-room cooling needs are ideal. Multi-zone ductless also works well for whole-home heating and cooling in many Fraser Valley homes - it’s not just an “addition only” option anymore.
How do I claim the heat pump rebate?
Most BC heat pump rebates require an HPSC-registered installer (Cohesive is registered) and pre- and post-install documentation. We file the paperwork that’s ours to file as part of the install. Some rebates require homeowner-side application - we walk you through that during the install closeout. For a full rundown, see our BC heat pump rebate guide.
When is the best time of year to install a heat pump?
Spring and fall are the easiest seasons - moderate weather makes the install simpler and you avoid losing heat or AC during a switchover. Summer and winter installs are absolutely doable; we plan the timing so the home isn’t without heating or cooling for more than a few hours during equipment changeover.
