Your Squamish House Is Too Hot. The Fix Is Probably Your Heating System.
It is July in the Squamish valley. Down on the waterfront the wind is doing its thing, the same wind that put us on every windsurfer's map. But head up the valley toward Brackendale and that breeze thins right out, the heat builds, and it sits. By three in the afternoon the upstairs is an oven. There is a new baby, or a home office, or a bedroom you have given up sleeping in. And somewhere around the second bad night you think: I should finally put in some air conditioning.
That is a completely reasonable thought. It is also the start of a much bigger conversation than you probably realize, and we would rather you know that going in than find out halfway through.
The question hiding inside the cooling call
Here is the thing almost nobody mentions when you call about "adding AC." In 2026, adding cooling to a home basically means installing a heat pump. A heat pump is an air conditioner that also happens to heat, very efficiently, all year. So the moment you decide to deal with summer, you have walked right up to the front door of your entire home heating decision.
In Squamish specifically, that door is wider than it used to be. We are now seeing homes, including newer high-efficiency builds and places that have had insulation and windows upgraded, where the cooling load is creeping up to nearly match the heating load. That is not normal for the coast. Vancouver mostly does not see it yet. Squamish does, because the valley traps heat the way a parked car does.
So when you call us in cooling season, we are not going to pretend the conversation is only about cooling. It is the sensible time to make the whole decision, and we mean that, not as a sales nudge. You are already motivated by the heat, you have time before winter, and you are not trying to organize a heating replacement in January when it is minus ten and every contractor in the corridor is booked solid. That is the only "why now" we will give you. No countdown timer.
The first question most people ask is the wrong one
Most homeowners open with "what equipment should I buy." That is the wrong first question. The right one is "how does my house actually want to be heated and cooled." Those are very different conversations, and the second one tells you what to do about the first.
We have had three of these calls recently, and two of them started with someone saying "I just want cooling."
One was a fellow in Squamish with a thirty-year-old furnace who came in for AC and left realizing the smarter move was the whole system, since his was near the end of its life anyway. Another was a young family in a manufactured home with a new baby, dreading the summer, where a clean and simple equipment swap was exactly right.
Same opening line. Completely different right answers.
There is no default. There is the answer your house needs, and the only way to find it is to look at the house as a system before anyone recommends a box of equipment.
Three things we spend our days un-explaining
"A heat pump means a giant electric heater and a panel upgrade I can't afford."
This is the most common fear, and it is mostly wrong. It comes from older heat pumps, and from systems that get sized lazily, both of which lean on a big electric backup heater that does need serious power. Here is the reality: most electrical panels are only using a fraction of the power that is actually connected to them. We pull your real consumption data from BC Hydro and look at what your home actually draws, not what a generic version of your home might draw. Nine times out of ten there is room. The trick is sizing the heat pump to carry the full load on the coldest day of the year, not just most of winter, so you never need the big backup heater in the first place. Do that, and you are running small circuits that draw less than the baseboards you already have. We have talked people out of five-figure panel upgrades they were told they needed and did not.
"A heat pump will blow up my hydro bill."
Funny thing about this one: we almost never hear it from our actual customers. We hear it from people at barbecues. The folks convinced a heat pump will wreck their bill are usually the ones who already decided to keep the furnace, so they never call us in the first place. A properly sized cold-climate heat pump is one of the most efficient ways there is to heat a home. The objection mostly survives on people who never tested it.
"Just put in the biggest, best one."
Oversizing is the single most common mistake in residential HVAC. A system that is too big costs more to buy, more to run, and keeps you no more comfortable. It just switches on and off more often. And sometimes the real answer is that a full heat pump conversion is the wrong call entirely. We looked at a home up in Whistler, three storeys, furnace in the basement, where a previous setup had a heat pump that two other companies had not been able to get working properly. Easy assumption: rip it out, put in a big new heat pump. But a heat pump delivers cooler supply air than a furnace, so it needs to move more of it, and the existing ductwork in that house could not push enough warm air up three storeys in a Whistler winter without leaning hard on backup heat. Leaning on backup heat kills the efficiency payback. The homeowner did not want to open every wall to resize the ducts. So the right answer was not the big sale. It was getting the existing furnace-and-heat-pump pairing working as it should. We would rather tell you that than sell you something that performs worse and costs more.
One corridor, three climates
This is the part that sets our region apart from the rest of the province, and it is why a contractor who only knows Vancouver is not automatically the right call as you head north. Run from the North Shore up the Sea-to-Sky and you pass through three pretty different houses.
North Vancouver sits right on the water, but the land climbs fast into the North Shore mountains right behind it, and that changes the whole picture. Pacific weather rolls in from the southwest, hits that wall of peaks, and gets forced upward. As the air climbs it cools, and the cooling squeezes the moisture out of it, the orographic effect at work. The result is a coastline that runs cooler and a good deal wetter than you would guess, and it gets cooler and wetter the higher up the slope a house sits. A home down near the water and one partway up the mountain can have meaningfully different needs, so the standing job here is managing rain, damp, and indoor air quality more than fighting temperature extremes. We walked through exactly how this plays out inside one real North Vancouver home in our post on adding cooling to a house where one room was left out.
Squamish is the heat-trap. The waterfront gets that famous wind, but up the valley the summer heat builds and sits, and we are now seeing homes where the cooling load is climbing to nearly match the heating load, which is not normal for the coast. Our wet shoulder seasons mean ventilation is usually about getting moisture out, so we have a lot of success with HRVs, heat recovery ventilators, which exhaust damp air while holding onto the heat.
Whistler is the opposite house again. Much higher heating load, and that heat has to land when it is far colder outside, which is exactly why cold-climate sizing matters so much up there. The ventilation logic flips too: in Whistler's deep winter, an HRV would pull in bone-dry mountain air and dry the house right out, so we switch to an ERV, an energy recovery ventilator, that holds the home's humidity where it should be while still bringing in fresh air. Same corridor, opposite strategy, an hour up the highway.
The rebate situation in 2026, the straight version
HVAC is expensive. Pretending otherwise would break the whole point of trusting us, so let's be straight about the money. Rebates can take a real bite out of the cost, but the landscape shifted recently and a lot of what people "know" is out of date. Here is where it stands as of June 2026.
The big rebates tied to switching off a gas furnace have largely wound down. The fuel-switching incentive ended in April 2025, and the heat-pump-plus-gas hybrid rebate closed at the end of 2025. So if a neighbour tells you they got thousands for ditching gas, they likely did it before those dates.
If you heat with electric baseboards or an electric furnace, switching to a qualifying heat pump can still get you up to $4,000 through the standard CleanBC stream, with no income test. This is the common one for older Squamish homes running a furnace downstairs and baseboards up.
There is a separate rebate for an electrical service or panel upgrade, around $500 in the standard stream and up to $5,000 if your household qualifies on income.
Income-qualified households can access far more. The maximum heat pump rebate in that stream was raised to $16,000, and full packages that bundle the panel, insulation, and ventilation have been reported up to around $24,000. Eligibility depends on household income and your home's assessed value, and the province has funded this through 2026-27, so it is not going anywhere this year.
Most of the bigger rebates require a pre- and post-install EnerGuide home assessment, which is itself rebated. Think of it as the gatekeeper: no assessment, no big rebate.
There is also a federal interest-free loan of up to $40,000 over ten years that can sit on top and spread the net cost out.
One catch worth knowing before you sign anything: most of these rebates require your contractor to be registered with the program before the work is quoted. If they are not, the rebate can vanish no matter how good the installation is. We are registered, and we handle that paperwork as part of the job.
Amounts and eligibility change constantly, so we confirm what is current for your exact situation before anyone commits a dollar. The official source to check is betterhomesbc.ca.
You probably don't need an architect
There is a persistent belief that a project like this needs a long line of consultants before anyone lifts a tool. For most homes up here, you don't. Housing falls under Part 9 of the building code, which is prescriptive, so as long as nobody is doing something structurally unusual, a heating and cooling upgrade does not need an architect or a stack of engineers signing off.
What you do need is someone who understands how the mechanical, electrical, and envelope pieces talk to each other, and who pulls the right permits. Every one of these installs needs one, and we handle that. The catch is that the paperwork changes with the address. In Whistler the municipality may also require a development permit, a check that the work fits its environmental and neighbourhood-character guidelines, which is a resort-town wrinkle. In Squamish you will not hit a development permit for a job like this. And the North Shore is not one jurisdiction but three, the City of North Vancouver, the District of North Vancouver, and West Vancouver, each running its own heat pump or mechanical permit process. West Vancouver even adds its own municipal rebate on top of the CleanBC ones. Which municipality you are in changes the steps, which is one more reason to use someone who works across all of them.
You don't need the answer before you call
That is what we are here for. The first conversation is about understanding your house and what you actually want, not pitching you on anything. If a heat pump is anywhere on your radar, even loosely, we put together a guide that walks you through the whole thing start to finish: what to expect, what to ask, where people most often get tripped up. It is called "Thinking About a Heat Pump? Read This First," and it is built so you can show up to any conversation, with us or anyone else, already knowing what you are walking into.
We are Porcupine Mechanical, a Squamish-based mechanical contractor working from the North Shore up through the Sea-to-Sky, from North Vancouver to Squamish to Whistler, on residential heating, cooling, and ventilation. Our whole thing is doing it efficiently and doing it right the first time.
