Frequently asked questions

According to RenoHouse, natural gas line run, meter to generator, typical 30-50 ft runs $1,200–$2,200 per project (CAD), and additional cost for gas line runs beyond 60 ft runs $500–$1,000 added to base run (CAD) (RenoHouse).

How do I choose a HVAC and fuel line contractor in the GTA?

Home Generator Index lists 74 HVAC and fuel line contractors at an average 4.77★ Google rating, the middle company sitting on 163 reviews. Take three from the shortlist above and get the scope written down. What to check before anyone opens a panel, including the ECRA/ESA licence number and who owns the gas half of the job, is set out on the methodology page.

Is there a season for gas line and HVAC work in Toronto?

Not in the way there is for outdoor trades. Demand runs Year-round and what fills the calendar is outages, not weather: an ice storm in winter, grid strain in summer. Both arrive with no notice and put an entire region in the queue on the same afternoon. Arranging the work in a quiet stretch buys a proper site visit and an unhurried conversation about sizing. Waiting until the power is out means competing with every neighbour for the same crew.

Will a contractor's cheque move it up this page?

No, and no business has an account here to pay through. The order comes from the Home Generator Index Score out of 100, built from what customers said, what the company states on its own website and how much is on its record. With 77% of the rated HVAC and fuel line contractors at 4.8★ or better, the positions are decided in narrow margins, so read past the first row. The methodology page sets out every input.

Natural gas or propane for a standby generator in the Greater Toronto Area?

Natural gas feeds off the utility supply and keeps running as long as the gas keeps flowing, which is the reason a standby unit outlasts a portable one that empties its tank overnight. Propane is the answer where there is no gas main: it needs a tank, a location for it, and refills you have to arrange. The generator itself is configured for one fuel or converted for the other, so ask which fuel the quote assumes before you compare two numbers.

Does the natural gas supply in the Greater Toronto Area affect what generator I can install?

It can decide it. A standby unit running on the utility gas supply does not empty a tank the way a portable does, which is the whole appeal, but it has to share the meter with the furnace, the water heater and everything else already connected. If the total exceeds what the meter and service can deliver, the utility has to upsize them, on its own schedule. Get the gas load calculation done before you settle on a model, not after the pad is in.
