AC replacements 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.

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.
