AC Replacement in Glencoe, MN
Our AC replacements in Glencoe run $5,200–$9,800 installed, with a written flat-rate quote from a Manual J and a 2-year labor warranty. Glencoe Light & Power, the city-owned utility, sets its own rates, so check them before choosing between an AC and a heat pump.
AC replacements in Glencoe homes
Replacing central air in Glencoe usually means replacing a retrofit on an older house. The new coil has to match the new condenser and fit the furnace below it, which in a tight basement sometimes means choosing a shorter coil or a new transition. Line sets from older installs are often undersized or kinked where they pass through the rim joist, and on an R-22 changeover we usually replace them. In older two-stories, the Manual J goes room by room, and the upstairs often needs a return added before any new condenser can keep it cool.
Glencoe Light & Power has supplied the city's electricity since 1938 and sets its own rates, so a heat pump in place of the AC should be judged on its rate against your gas cost. The federal SEER2 minimum for a new split AC in Minnesota is 13.4, and with a short cooling season, a mid-range SEER2 with two-stage operation often makes more sense than the top tier.

What affects the price of a new central AC in Glencoe?
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.
AC replacement in Glencoe: questions
Can we put a new AC in our Glencoe house without replacing the furnace?
Yes, if the furnace is sound. The new coil sits on the existing furnace, so we check that its blower can deliver the airflow the new system needs and set the speed to match. On older furnaces with a coil squeezed on top, we may need a shorter coil or a new transition. If the furnace is past about 20 years, we'll show you the cost of doing both at once.
Should our Glencoe house get a heat pump or a plain AC, given Glencoe Light & Power's rates?
Compare them on your own numbers. A heat pump costs more installed, $7,500–$14,500 with us, but it also heats in spring and fall and can offset gas use. Glencoe Light & Power sets its own electric rates, so the savings depend on that rate against your gas cost, and we work through both with a year of your bills. Keeping the gas furnace as backup for the coldest weeks is the usual pairing.
