AC Replacement in Richfield, MN
A new central air system in Richfield costs $5,200–$9,800 installed with us, flat-rate and in writing. Houses the airport noise program sealed up often need less tonnage than the old unit, so the size comes from a Manual J calculation. Xcel Energy is Richfield's electric utility, and its cooling rebates change yearly.
AC replacement calls in Richfield homes
Replacing a noise-program air conditioner in Richfield usually means a new condenser, a coil matched to its refrigerant and a hard look at the line set, which may be reusable if its size and condition suit the new unit. In a low basement the new cased coil plus the furnace can come out taller than the old stack, so we measure from the floor to the duct before choosing a coil or a transition.
Condenser placement on a narrow lot means keeping the unit clear of the neighbor's bedroom window and giving it the side clearance the manufacturer lists. Xcel Energy runs Residential Cooling Rebates, Saver's Switch and AC Rewards for smart thermostats. With CenterPoint Energy on the gas side, a heat pump is worth pricing: CenterPoint's ducted air-source heat pump rebate applies when the heat pump is paired with a gas furnace, and Xcel has its own heat pump rebates. The city requires a permit for the replacement.

AC replacement in Richfield: questions
Would a heat pump work in a 1950s Richfield rambler?
Yes, usually as dual fuel. A rambler with ducts in the basement is a good match for a ducted heat pump that cools in summer and heats down to a set outdoor temperature, with the gas furnace taking over below it. CenterPoint's ducted heat pump rebate only applies when the heat pump is paired with a gas furnace. Xcel's heat pump rebates may require a Trade Partner Network contractor, so ask Xcel before counting on one.
Will a new AC coil fit on the furnace in our low Richfield basement?
Usually, with some planning. New cased coils for today's refrigerants are sometimes taller than the old ones, and some Richfield basements have only inches between the top of the plenum and the joists. We measure before choosing equipment. Options include a shorter coil model, reworking the supply plenum, or replacing an aging furnace at the same time with one that leaves more room above it.
