Question 1

How much does a home standby generator cost in Vancouver?

Accepted Answer

Most fully installed air-cooled whole-home systems for a typical Metro Vancouver house land in the $12,000–$22,000 range once you include the generator, automatic transfer switch, pad, gas line work, electrical labour, permits and commissioning. Smaller essential-circuits systems can start lower, and large liquid-cooled units for big hillside homes run higher. The three biggest cost drivers are the size of the unit, the distance from the gas meter and panel, and whether your electrical service needs upgrading.

Question 2

What size generator do I need for my home?

Accepted Answer

Sizing should come from a load calculation, not a rule of thumb. We total the running load of what you want powered, then add the starting surge of the largest motors — usually a heat pump, air conditioner, well pump or sump pump. A 2,000 sq ft gas-heated home often lands around 14–18 kW. An all-electric home with a heat pump, electric hot water and an EV charger can need 22–26 kW or more. Oversizing wastes money and undersizing causes nuisance shutdowns, so the calculation matters.

Question 3

Does a standby generator turn on automatically?

Accepted Answer

Yes. A permanently installed standby system monitors utility voltage continuously. When power fails, the automatic transfer switch safely disconnects your home from the grid, the generator starts, and power is restored — typically within 10 to 30 seconds. When utility power returns and stabilizes, the switch transfers back and the generator shuts down and cools off. Nobody has to be home, and nothing has to be plugged in.

Question 4

Can I power my whole house, or only some circuits?

Accepted Answer

Both are valid designs. Whole-home coverage backs up the entire panel and is the most convenient option. An essential-circuits design backs up a selected subpanel — furnace or heat pump, fridge and freezer, sump pump, well pump, internet, lights and a few outlets — for less money. Modern load-management modules can also shed big loads like an EV charger or hot tub automatically, letting a smaller generator cover a whole house.

Question 5

Natural gas or propane — which is better here?

Accepted Answer

Natural gas is the better choice almost everywhere in Metro Vancouver where service exists: unlimited runtime, no tank, no refuelling and nothing to manage during a storm. Propane is the answer for acreages and upper-slope properties outside the gas network, and it stores well, but you have to size the tank for realistic multi-day runtime and keep it topped up. Diesel is used mainly for commercial and large residential applications.

Question 6

How loud is a home generator?

Accepted Answer

Modern enclosed air-cooled units run around 60–67 dB(A) at a typical measuring distance — comparable to a central air conditioner or a normal conversation. Placement matters as much as the spec: keeping the unit away from bedroom windows, respecting municipal noise bylaws and setbacks, and using the enclosure's sound-attenuating design all keep neighbours comfortable.

Question 7

Do I need permits to install a generator?

Accepted Answer

Yes. A compliant residential installation involves an electrical permit, a gas permit for the fuel connection, and in many municipalities a mechanical or building permit for the pad and placement. Work must meet the Canadian Electrical Code and BC gas requirements, and it is inspected. Permitted, inspected work also protects your home insurance position and your property resale value.

Question 8

How long does installation take?

Accepted Answer

From signed quote to commissioning is usually two to six weeks, depending on equipment availability and municipal permit turnaround. The physical work on site is typically one to three days: pad preparation, setting the unit, running the gas line, installing the transfer switch, terminating at the panel, then start-up, load testing and a walkthrough.

Question 9

How long can a standby generator run continuously?

Accepted Answer

On natural gas, a properly installed unit can run for days. Manufacturers recommend a brief shutdown for an oil check and cool-down after roughly 24 hours of continuous operation, then it can be restarted. Propane runtime depends on tank size and load — a 500-gallon tank typically supports several days of realistic household use.

Question 10

What maintenance does a generator need?

Accepted Answer

An annual service is the baseline: oil and filter, air filter, spark plugs on schedule, battery test, valve-lash check on schedule, and a load test to confirm it will carry your house. The unit also self-exercises weekly for a few minutes. Battery failure is the single most common reason a generator does not start when needed, which is why the annual battery test matters.

Question 11

Is a portable generator a safe alternative?

Accepted Answer

A portable generator can cover a fridge and a few lights, but it has real limitations: someone has to be home to set it up, it needs fuel during the storm, it cannot be run indoors or in a garage because of carbon monoxide, and it must never be back-fed into a wall outlet. If you do use a portable, have an interlock or manual transfer switch professionally installed and keep the unit well away from doors, windows and vents.

Question 12

Will a generator protect my food during an outage?

Accepted Answer

Yes, and this is one of the most common reasons homeowners install one. A full fridge holds safe temperature for roughly four hours and a full freezer for about 24 to 48 hours. Beyond that, food safety guidance is to discard perishables. A single multi-day outage can easily cost $500–$1,500 in spoiled groceries, plus the inconvenience of replacing it all.

Question 13

Does a generator keep my heat and hot water running?

Accepted Answer

It can. A gas furnace or boiler needs only modest electrical power for its blower, controls and pump, so it is easy to back up. Heat pumps and electric hot water tanks draw much more and need to be included in the load calculation. In a cold snap, keeping heat running also protects your plumbing from freezing and bursting.

Question 14

Will backup power keep my sump pump and drainage working?

Accepted Answer

Yes, and in low-lying areas like Richmond, Ladner and parts of Burnaby that is often the strongest reason to install one. Storms that knock out power are the same storms that overload drainage, so the pump is needed exactly when the grid is down. One avoided basement flood frequently exceeds the cost of the system.

Question 15

Does a generator add value to my home?

Accepted Answer

A permanently installed, permitted standby system is a fixture that appraisers and buyers recognise, particularly on the North Shore and in outage-prone hillside and rural neighbourhoods. Beyond resale, it protects against real losses: spoiled food, water damage, frozen pipes, lost remote-work income and hotel stays during extended outages.

Question 16

Can a generator support medical equipment at home?

Accepted Answer

Yes — households that rely on oxygen concentrators, CPAP machines, home dialysis, powered mobility or refrigerated medication are exactly who automatic backup power is designed for. Because the transfer is automatic and happens within seconds, there is no window where someone has to manually start anything. Critical medical circuits should be identified during the load calculation so they are guaranteed coverage.
