Central air in Circle Pines, where 1950s–60s houses have ducts sized for heat, runs $5,200–$9,800 installed with us, flat-rate and written. Electricity in town comes from Connexus Energy or Xcel Energy depending on the address, so we check your bill before pointing you to a rebate or program.
Most AC replacements in Circle Pines are second- or third-generation systems on 1950s and 60s houses, so the job starts at the furnace: a new cased coil matched to the condenser's refrigerant, a clean transition into the plenum, and a hard look at the return, which is often the weak link in these houses. A line set of the right size in good condition may be reused; otherwise it's replaced.
Outdoors, the unit needs its listed clearances on a level pad, away from bedroom windows and out from under the heaviest seed drop if the yard allows. With Centennial gas already feeding the furnace, a heat pump in place of the AC is worth pricing. A replacement normally needs a city mechanical permit; ask us how it shows on your quote.

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.
Connexus Energy members can claim heat pump rebates for ducted, ductless and geothermal systems plus a central AC rebate, while homes on the Xcel Energy side can use Xcel's AC rebates and its Trade Partner Network heat pump rebates. Rebate programs change every year, so check the utility's current terms before you buy.

Yes, that's a dual-fuel setup. The heat pump cools in summer and heats through spring, fall and milder winter days, and the gas furnace takes over below a changeover temperature we set. Where that point lands depends on Centennial's gas price against your electric rate from Connexus Energy or Xcel Energy. Both utilities run heat pump programs with their own rules, so ask whether the rebate needs a registered contractor.
Connexus publishes a list of qualifying Wi-Fi thermostats and its enrollment terms, so check them before choosing the thermostat, and the home needs reliable Wi-Fi. If you plan to enroll, choose the thermostat before the install so it's wired once.
