AC Replacement in North St. Paul, MN
Central air replacement in North St. Paul runs $5,200–$9,800 installed with us, flat-rate and in writing, with the size set by a Manual J load calculation. The electric side here is the city's own utility, so its AC and heat pump rebates, not Xcel's, are the ones to check before you buy.
AC replacement calls in North St. Paul homes
Replacing central air in North St. Paul usually means a new condenser, a coil matched to it and a look at the line set, which may be reusable if its size and condition suit the new unit. In postwar houses the return side gets measured, since ducts laid out for heat often can't feed a new system its rated airflow, and a remodeled house may need a return for the rooms that were built on.
The electric utility matters here. North St. Paul's city-owned utility has offered rebates on quality-installed central air conditioners and air-source heat pumps, so ask it what documentation the install needs before work starts. A heat pump in place of the AC cools the same way and heats through spring and fall, with the gas furnace, on Xcel's gas, handling deep cold. In townhome associations, the condenser location and screening usually need approval. We pull the permit.

How much does a new central AC cost in North St. Paul?
A new central air conditioner from us runs about $5,200–$9,800 installed in North St. Paul, sized with a Manual J load calculation. Same prices in North St. Paul as in every town we serve. See the AC replacement cost guide or furnace and AC together.
Are there rebates for a new air conditioner in North St. Paul?
North St. Paul splits its programs between two utilities. For a new gas furnace, look to Xcel Energy's heating equipment rebates, whose page points you to participating contractors, so settle that question before choosing an installer. For central air and heat pumps, look to the city's electric utility, which runs its own rebates; its recent list covered central AC tune-ups, quality-installed central air conditioners and air-source heat pumps, and ENERGY STAR smart thermostats, filed within a year of purchase. The city posts each year's forms separately. Rebate programs change every year, so check the utility's current terms before you buy.

AC replacement in North St. Paul: questions
What does 'quality installed' mean for North St. Paul's AC rebate?
Utility programs use the term for an install checked against a standard: sizing from a load calculation, a coil matched to the outdoor unit, verified airflow and a refrigerant charge set by measurement. Each program writes its own checklist and form, and the city's is the one that counts here, so ask the city for its current requirements before the install. We size with Manual J and set the charge by superheat or subcooling on every system anyway.
Is there a North St. Paul rebate for a smart thermostat to go with the new AC?
The city's electric utility has included ENERGY STAR smart thermostats on its recent rebate list, filed within a year of purchase with a dated receipt. Xcel's AC Rewards thermostat program is tied to Xcel electric service, so it doesn't fit a North St. Paul home. If you add a smart thermostat with the new AC, we wire it properly, including a C-wire if the old thermostat lacked one, and set its staging to match the new equipment.
