Mostly the electric programs. Nearly all of Columbus buys power from Connexus Energy, but the state's service-area map puts a small area in the northeast corner in Xcel territory. There, AC rebates, Saver's Switch and AC Rewards come from Xcel, and Xcel's heat pump rebates come with its Trade Partner Network rules. A furnace rebate, if you have natural gas, follows the gas bill instead.

Often, and a large lot helps, because a horizontal loop in trenches usually costs less than drilled vertical bores. The loop field has to stay clear of your well and septic drainfield. Connexus Energy offers ground-source rebates and points members to the Minnesota Geothermal Heat Pump Association to find installers. National cost guides such as HomeGuide put systems at $20,000–$50,000+ before incentives, so compare it with an air-source heat pump first.

Not in the amounts a furnace produces. On a cold day a condensing furnace sends a few gallons of slightly acidic water down the drain, far less than one load of laundry. Some owners prefer to pass it through a limestone neutralizer on the way, which we can mount on the drain line. Don't route it outdoors to spare the tank: an outside line freezes shut, the trap backs up and the furnace stops.

Not automatically. Wind across fields and marsh raises air leakage, and a Manual J load calculation factors that in, along with the windows, insulation and Minnesota's design temperatures. Oversizing to be safe backfires, since a big furnace runs in short bursts, leaves rooms uneven and wears out sooner. On a windy site, sealing the rim joist, attic hatch and old window frames often cuts more heat loss than extra furnace capacity can make up.
