Central air on a Nowthen lot runs $5,200–$9,800 installed. Connexus Energy supplies power across Nowthen and offers a central AC rebate and heat pump rebates, so we compare both before you buy.
Replacing central air in Nowthen usually starts with a choice between a straight AC and a heat pump. On a propane house, a heat pump that cools in summer and heats in spring and fall can cut the propane bill, with the furnace covering the deep cold. Either way, the indoor coil is matched to the outdoor unit's refrigerant, the line set gets measured and inspected, and the condenser goes on a level pad with its listed clearances, close enough to the house to keep the line set short.
Connexus Energy's heat pump programs need a state electrical inspection before Connexus activates them, so the electrical work, including the disconnect and circuit, is done to pass that inspection the first time. Ask whether the rebate needs a registered contractor.

What moves an AC quote within that range: tonnage from the Manual J load calculation, the SEER2 rating, a new coil and line set, and any electrical work. See the AC replacement cost guide or furnace and AC together.
Yes. Connexus Energy requires a state electrical inspection before it activates its air-source heat pump and dual-fuel programs, and it charges a one-time equipment fee. It also says it validates parts of the installation with its trade partners, so ask Connexus whether that affects your rebate. That inspection covers the install's electrical work, and Connexus completes its setup once it passes.
On a level pad with the clearances the manufacturer lists, close enough to the house to keep the line set short, out from under roof drip lines and away from where drifts pile up. Open rural lots give room to choose, and we measure the line-set route and its height limits before settling on a spot. A heat pump also needs to sit above the snow line because it runs all winter.
