For generator installation in Mississauga, Platinum works with homeowners and small businesses alike. We are a Generac dealer and licensed electrical contractor, and our own electricians handle the design, wiring and service.
Mississauga is large enough that there is no single typical home. Port Credit and Lakeview sit on the lake, Lorne Park and Mineola have large lots and mature trees, Streetsville has older homes around its historic core, and Erin Mills and Meadowvale are mostly subdivisions from the 1970s to 1990s, now old enough that many have had their panels and furnaces replaced.
The city also has a great many small businesses, from offices and plazas to industrial units along its major corridors. For those owners, an outage means lost trade or spoiled stock, and the backup question is more about the cost of downtime.
Platinum serves all of Mississauga. Read about Generac home generators and our commercial generators, or request a free consultation.

Alectra Utilities is the electricity distributor across Mississauga, and natural gas may be available where Enbridge Gas service is available at the property. Platinum confirms the service and fuel details for your specific address during the consultation.
Homes from the 1970s and 1980s often have a panel that was upgraded at some point, sometimes in a finished basement with little room around it. The transfer switch has to be close to that panel, or wired with a longer run. We work this out first, as it can affect the cost more than the size of the generator does.
Lorne Park, Mineola and the lakefront neighbourhoods have heavy tree cover over overhead lines. That is lovely in July but a concern in an ice storm, when limbs come down and repairs can take a while. These lots usually have room for a generator, though sound and appearance matter to the neighbours.
Newer infill and rebuilt houses can carry much larger loads than the home they replaced, particularly with multiple air conditioners. We calculate the load rather than judging by the home's size.
For businesses, three-phase service is common. Air-cooled home units are single-phase, so a commercial site may call for a liquid-cooled generator such as a 25kW or larger, which comes in 3-phase versions. Single-phase offices and small shops may have more options.
For homeowners, a good place to start is a list of what you lost in the last outage. If the answer was a flooded basement, the plan begins with the sump pump. If it was heat or a spoiled freezer, the list may be short enough for a smaller generator. If you want everything to keep running, we look at whole-house backup with load management. A clear priority list leads to a better design, and often to a lower price.
At home, the priorities are the familiar ones: sump pump, furnace, fridge, internet and lighting, plus central air in a summer outage. Older family members and anyone using medical equipment may need more, and it is worth planning that from the start.
For a business, list what actually stops work: point-of-sale, refrigeration, servers, phones, security, and HVAC. Then we can tell you what it would take to keep those on, rather than the whole building.
With a standby generator, power returns automatically within seconds of an outage. Sensitive electronics may still need a small battery unit to ride through those seconds, and we can tell you where that makes sense.

For homes, we look at the panel, gas meter, side yards and large loads. For businesses, we look at the service size and phase, the loads you need to keep running, and any tenant or landlord approvals.
If you are a tenant in a plaza or an industrial unit, your landlord may need to approve the location, so it is best to bring them in early.
Ask us about financing or monthly rental for residential systems.
Many Mississauga homes on 200A service fall between an 18kW and a 26kW. Older homes on 100A service may need less, and may be better off with a smaller unit and some load management.
Larger homes with two air conditioners may want to compare a 28kW air-cooled unit with a liquid-cooled one. On natural gas, the 28kW delivers 25 kW, so it is worth doing the math against that lower figure.
For businesses, we start with a load study. If you have utility billing data or a demand reading, that helps a lot.
Our guide on how to choose the right kW size explains how the numbers work, and we confirm them against your own panel.
Often considered for furnace blower, fridge, sump pump, lights, internet, and selected circuits.

Yes. We install for offices, shops and light-industrial units. We start by identifying which loads you need to keep running, and whether you have single-phase or three-phase service.
Home air-cooled units are single-phase. For three-phase, you would look at a liquid-cooled commercial generator. We can tell you what your building has.
If you lease, almost certainly. The location, the gas line and the electrical work all affect the building, so bring your landlord in early. We can give them the details they need.
Not always. We look at its condition and capacity, and how the transfer switch can connect. If it needs work, we will explain why and what it costs.
A 22kW runs at about 67 dB(A) at normal load at 7 metres, and its weekly test is quieter still at about 55 dB(A). We locate it to reduce the sound reaching neighbours.
It depends on the generator size, single-phase or 3-phase service, the length of the gas and wire runs, and any panel work. We give you a written quote after reviewing your property, and financing and monthly rental are available.
Yes, in most cases, for homes and businesses. Send us the model and serial number.
