Generacs do fine in cold, snowy weather. We’re outside of Buffalo NY, the town next to Orchard Park. Our house 10 minutes from where the Buffalo Bills play. If you’ve seen any of their famous winter games, you know it gets really cold & snowy here. We got a 13K standby generator in 2019 for about $7K. They have higher wattage models that fully power larger homes. It powers our whole house & has power to spare. The longest it’s run at 1 time so far is 18 hours. But our power goes out a few times a year, sometimes even in clear sunny weather, for several hours at a time. On Father’s Day, it went out for 5 hours. No idea why, weather was fine. ( Yea, our power company is great.

). We had it installed by the same Heating & Cooling company that installed our furnace & AC earlier that year. We have them come once a year to do routine maintenance on all 3 units for about $350. No searching for repair services, that company can handle anything that comes up.
Before we got our generator, there were very few houses in our area that had them. Over the last 3-4 years, more & more homes are getting them. And almost every one is a Generac. Very rarely do I see any other brand. The Generac has extra insulation to accommodate for our cold weather. Neighbors had theirs for 10 years, it runs for 15 minutes once a week. Ours runs 5 minutes every other week. The most effort we have to put in is to call & schedule our annual maintenance visit. IMO don’t rule out a Generac just because you live in a cold area. They’re fine & also highly rated.
