AC Replacement in Columbus, MN
We replace central air on Columbus houses for $5,200–$9,800 installed, flat-rate and in writing, with a matched coil and a Manual J sizing. On propane houses, a heat pump that also carries spring and fall heating is worth pricing against a straight AC.
AC replacements in Columbus homes
Replacing an AC on a 1960s or 70s Columbus house calls for a new condenser, an indoor coil built for its refrigerant on top of the existing furnace, and a check of the ductwork, which was often sized for heat long before central air arrived. Older line sets that don't suit the new refrigerant or size get replaced; newer ones can sometimes stay.
A big lot gives options outdoors, but the condenser still belongs close to the house to keep the line set short, on a level pad, out of the mower's path and away from roof runoff. The electrical side, including the disconnect and circuit, falls under a state electrical permit in Columbus. Connexus members can add a central AC rebate and the Wi-Fi PowerNap program. On a propane house, pricing a heat pump against a straight AC makes sense, because the heat pump also covers spring and fall heating that propane would otherwise carry.

What affects the price of a new central AC in Columbus?
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.
Are there rebates for a new air conditioner in Columbus?
Connexus Energy, the electric co-op for nearly all of Columbus, pays rebates on ducted and ductless air-source heat pumps, ground-source systems and central air, and offers a lower dual-fuel rate and Wi-Fi PowerNap. Ask us which rebates apply when we quote. Rebate programs change every year, so check the utility's current terms before you buy.

AC replacement in Columbus: questions
How big should a heat pump be alongside the propane furnace in our Columbus house?
Sized to the cooling load, which a Manual J sets, rather than to cover every winter hour. The propane furnace handles the coldest days, so the heat pump doesn't need to be oversized for January, and an oversized one short-cycles and dehumidifies poorly in July. A cold-climate model keeps heating well below freezing. We set the changeover temperature so the heat pump runs whenever it's cheaper than propane.
Can a new AC or heat pump on our Columbus house use the old electrical circuit?
Often, but the nameplate decides. Every outdoor unit lists a minimum circuit ampacity and a maximum breaker size, and the existing wire and breaker have to match them. A like-for-like AC swap usually reuses the circuit. A heat pump with electric backup strips needs much more capacity, which is one reason pairing it with the propane furnace makes sense.
