British Columbia broke at least 24 daily temperature records on May 3, 2026 alone — and Metro Vancouver is forecast to feel above 30°C through the first week of May. If your home has no air conditioning, you are not alone: the majority of homes in the Lower Mainland were built without cooling. But with heat waves arriving earlier and hitting harder every year, that needs to change. Grove Mechanical installs ductless mini-splits, heat pumps with cooling, and central AC systems across Metro Vancouver, Surrey, Langley, Burnaby, Coquitlam, Abbotsford, Chilliwack, and the entire Fraser Valley — with free estimates and full rebate support.
What Just Happened: The May 2026 BC Heat Wave
On May 3, 2026, a Rex block — an atmospheric pattern where high pressure locks over the West Coast — sent temperatures soaring 5 to 15°C above normal across British Columbia. Environment and Climate Change Canada confirmed at least 24 new daily maximum temperature records were broken in a single day:
- Chilliwack: 30.8°C — nearly 14°C above normal for early May
- Lillooet: 31.1°C — breaking a record set in 1937
- Port Alberni: 29.8°C — breaking a 1907 record by over 3°C
- Victoria Harbour: 26.9°C — breaking a record that had stood since 1898
- Metro Vancouver: Humidex readings above 31°C on May 4, with Abbotsford running 13°C above seasonal
ECCC meteorologist Bobby Sekhon described the event as "quite exceptional heat in early May" and noted that no measurable rain is forecast for the South Coast for the foreseeable future. This is not a one-day anomaly — it is a pattern that climate scientists say will become more frequent and more intense in coming years.
Why Most Lower Mainland Homes Have No Cooling
The Lower Mainland was historically mild enough that air conditioning was considered optional. Homes built before 2000 — and many built since — were designed with heating as the priority. Ductwork, if it exists at all, was sized for a furnace, not a central air system. The result is that when temperatures spike, hundreds of thousands of homeowners have no good options beyond fans and open windows.
The good news: modern cooling solutions no longer require existing ductwork. Ductless mini-split systems can be installed in a single day, require only a small hole through the wall, and cool individual rooms or entire homes with impressive efficiency. And if you want whole-home heating and cooling in one system, a heat pump does both — and qualifies for up to $16,000 in BC government rebates.
Your Cooling Options in the Lower Mainland
Option 1: Ductless Mini-Split (Most Popular for BC Homes)
A ductless mini-split consists of an outdoor compressor unit and one or more indoor air handlers mounted high on the wall. Installation typically takes one day, requires no ductwork, and can cool a single room or multiple zones across your home. Brands like Mitsubishi, Fujitsu, and Midea offer units specifically rated for BC's climate.
Best for: Homes without ductwork, condos, older Vancouver homes, additions, and anyone who wants fast installation.
Cost in Metro Vancouver (2026): $3,500–$7,500 for a single-zone system; $7,500–$18,000 for multi-zone whole-home coverage.
Rebates: Single-zone mini-splits qualify for up to $4,000 through BC Hydro. Multi-zone systems that provide whole-home heating and cooling qualify for up to $16,000 through CleanBC and FortisBC stacked programs.
Option 2: Heat Pump (Best Long-Term Value)
A heat pump is a single system that heats your home in winter and cools it in summer — replacing your furnace and adding air conditioning in one installation. Modern cold-climate heat pumps work efficiently down to -30°C, making them ideal for BC's climate. They are the most energy-efficient option available and the best way to reduce your home's carbon footprint.
Best for: Homeowners looking to replace an aging furnace, maximize efficiency, and qualify for the largest rebates.
Cost in Metro Vancouver (2026): $12,000–$30,000 fully installed depending on system size and home configuration.
Rebates: Up to $16,000 through CleanBC Better Homes + FortisBC stacked programs (as of April 1, 2026). Income-qualified households may be eligible for even more.
Option 3: AC Add-On to Existing Furnace
If you have a forced-air furnace with ductwork, adding a central air conditioning coil and outdoor condenser is often the most cost-effective way to cool your whole home. The existing ductwork distributes the cool air through every room.
Best for: Homes with existing forced-air furnaces and ductwork in good condition.
Cost in Metro Vancouver (2026): $5,500–$10,000 fully installed.
Rebates: Standard central AC add-ons do not qualify for CleanBC rebates. However, upgrading to a heat pump coil (dual-fuel system) may qualify for partial rebates.
How Long Does Cooling Installation Take?
One of the most common questions we hear during heat waves is: how fast can you install it? Here is a realistic timeline for each system type in Metro Vancouver:
- Single-zone ductless mini-split: 4–8 hours on the day of installation. From first call to cool air: typically 1–2 weeks depending on equipment availability.
- Multi-zone mini-split (2–5 zones): 1–2 days of installation. Timeline from booking: 1–3 weeks.
- Heat pump (ducted or ductless): 1–3 days of installation. Timeline from booking: 2–4 weeks (longer if electrical panel upgrade is needed).
- Central AC add-on: 1 day of installation. Timeline from booking: 1–2 weeks.
The most important thing you can do right now is book your free estimate. During heat waves, HVAC companies across the Lower Mainland fill up within days. The homeowners who call today are the ones who are cool by next week.

- Stacking: BC Hydro, CleanBC, and FortisBC rebates can be stacked for maximum savings
Note: Standard central AC add-ons (cooling only, no heating) do not qualify for most rebate programs. To maximize your rebate, choose a heat pump that provides both heating and cooling. See all available BC rebates →
Frequently Asked Questions
How much does AC installation cost in Metro Vancouver in 2026?
A single-zone ductless mini-split typically costs $3,500–$7,500 fully installed. A multi-zone system for whole-home coverage runs $7,500–$18,000. Central AC added to an existing furnace costs $5,500–$10,000. A full heat pump system (heating and cooling) costs $12,000–$30,000 before rebates — and after stacking CleanBC and FortisBC rebates, the net cost can drop significantly. All prices are in CAD and include equipment, labour, and permits.
Can I get AC installed during a heat wave? How fast?
Yes — a single-zone ductless mini-split can be installed in as little as one day once equipment is available. The bottleneck is usually equipment availability and scheduling, not the installation itself. During a heat wave, demand spikes and wait times extend. Call as early as possible. Grove Mechanical offers free same-day estimates and works to schedule installations as quickly as possible.
Do I need a permit for AC installation in BC?
Yes. Most cooling system installations in Metro Vancouver require a mechanical permit from your municipality. Grove Mechanical handles all permitting as part of every installation — you do not need to manage this yourself.
What is the difference between a heat pump and a ductless mini-split?
A ductless mini-split is a type of heat pump. All heat pumps can both heat and cool. The term "heat pump" is often used to describe ducted systems that replace a furnace, while "ductless mini-split" refers to wall-mounted systems that work without ductwork. Both are highly efficient and both qualify for BC rebates when they provide whole-home heating and cooling.
Does my condo qualify for cooling rebates in BC?
Yes — condo and strata unit owners can qualify for CleanBC rebates on ductless mini-split systems. Income-qualified condo owners may be eligible for up to $5,500 for a ductless mini-split. Strata approval may be required for outdoor unit placement.
Which cooling system is best for a Vancouver home without ductwork?
A ductless mini-split heat pump is the best option for homes without existing ductwork. It requires only a small hole through the wall for the refrigerant lines, installs in one day, and provides both cooling in summer and heating in winter. It is the most popular cooling solution for older Vancouver homes, condos, and any property where running new ductwork is not practical.
Will BC have more heat waves in the future?
Climate scientists and Environment Canada have consistently noted that extreme heat events in BC are becoming more frequent and more intense. The 2021 heat dome — which saw Lytton reach 49.6°C — was described as a once-in-a-millennium event, yet similar heat events have occurred multiple times since. Installing a reliable cooling system is no longer a luxury for Lower Mainland homeowners — it is a practical necessity.
