For $5,200–$9,800 installed, a Nowthen house gets new central air from us, flat-rate and in writing, with a coil matched to the condenser and sizing from a Manual J. 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 programs apply citywide: a central AC rebate for higher-efficiency units, heat pump rebates, the dual-fuel rate and Wi-Fi PowerNap. Its 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.

A new central air conditioner from us runs about $5,200–$9,800 installed in Nowthen, sized with a Manual J load calculation. Same prices in Nowthen as in every town we serve. See the AC replacement cost guide or furnace and AC together.
Connexus Energy supplies electricity across Nowthen, so its programs apply citywide: heat pump rebates (air-source, ductless and ground-source), a central AC rebate, a reduced-rate dual-fuel program that accepts a propane, natural gas or oil furnace as backup, and the Wi-Fi PowerNap program. Check whether each rebate calls for a registered contractor. Homes with natural gas should check the gas company on their bill for furnace rebates. The state's HEAR and HOMES rebates are still not open in Minnesota. Rebate programs change every year, so check the utility's current terms before you buy.

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. The electrical work is permitted and inspected as part of the install, and Connexus completes its setup once the inspection passes.
A rebate on higher-efficiency central air, which Connexus recommends pairing with a Wi-Fi thermostat enrolled in PowerNap, the summer program that can cycle your AC during peak demand in exchange for a rebate. Check Connexus' current efficiency requirements before picking a model; utilities usually ask for the AHRI certificate that matches the condenser and coil. Heat pumps have separate Connexus rebates, so price both before deciding.
