AC Replacement in Shorewood, MN
Expect $5,200–$9,800 installed for a central AC replacement in Shorewood, written and flat-rate, sized by Manual J. Many Shorewood homes have grown additions or run separate systems for the main floors and lower level, so each system gets its own load calculation and its own price.
AC replacement calls in Shorewood homes
A Shorewood AC replacement often starts with the question of what the system is supposed to cool now. A house that added rooms over the years may need a different size, or the same size plus duct work, to reach the addition. Where a house has two systems, each gets sized for its own zone, and a walkout lower level may be better served by humidity control than by more cooling.
Placement on a lake lot takes some care. The condenser shouldn't sit under a deck or where it's the loudest thing on the patio, and on wooded lots it belongs out from under trees that shed cottonwood. On the islands, getting a condenser to the lot is planned in advance. For Xcel Energy customers there are Residential Cooling Rebates and AC Rewards. Because CenterPoint Energy handles the gas, a heat pump paired with the furnace can qualify for CenterPoint's ducted heat pump rebate, and Xcel has heat pump rebates too. We take care of the permit.

How much does a new central AC cost in Shorewood?
A new central air conditioner from us runs about $5,200–$9,800 installed in Shorewood, sized with a Manual J load calculation. Same prices in Shorewood 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 Shorewood?
Shorewood is on CenterPoint Energy gas and Xcel Energy electricity. For the many furnace-and-AC pairs from the 1970s and 1980s, CenterPoint's rebates cover a high-efficiency furnace installed by any dealer, and Xcel's cooling rebates cover the new air conditioner or heat pump; ask whether Xcel's rebate needs a registered contractor. CenterPoint also has a rebate for a ducted heat pump paired with a gas furnace, and Xcel's AC Rewards program pays an annual reward for letting it adjust an enrolled smart thermostat on peak days. Rebate programs change every year, so check the utility's current terms before you buy.

AC replacement in Shorewood: questions
Will a new AC cool the addition on our Shorewood house?
Only if the air can get there. Additions often have a long supply run through an unconditioned space, undersized ducts and no return, so a new condenser doesn't change much on its own. During the quote, we measure the airflow at the addition's registers. The fix may be a new or larger duct run, a return, or a single ductless head in the addition on its own thermostat, which also heats it in spring and fall.
Can the new condenser go on the lake side of our Shorewood house?
It can, but it's often not the best spot. The lake side usually holds the patio, deck and the view, and a condenser there is the noisiest thing in the yard on a summer evening. It can't go under a deck. A side yard with a short line-set run to the furnace, open air above, and some distance from bedroom windows usually works better. We'll show you the options on the quote visit.
