Central air in East Bethel costs $5,200–$9,800 installed with us, sized by Manual J and quoted flat-rate in writing. On propane, a ducted heat pump in place of the AC also carries spring and fall heating.
Many East Bethel AC replacements are really a heating question too. A home on propane can swap the air conditioner for a ducted heat pump, which cools like an AC and also heats the house through most of spring and fall, and Connexus Energy bills that heating at a lower rate when an automatic backup furnace is in place. Homes on CenterPoint Energy gas can pair the heat pump with the gas furnace and look at CenterPoint's ducted heat pump rebate, which requires that pairing.
For a straight AC swap, the coil gets matched to the new condenser and refrigerant, and the line set is checked or replaced. Manufactured homes need a coil that fits the downflow furnace's cabinet and a condenser sized to the home's ducts, not the old nameplate. On Coon Lake Beach's small lots, a quiet two-stage condenser set away from the neighbor's bedroom window is worth the planning.

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.
East Bethel is Connexus Energy territory for electricity, so the co-op's programs apply whether you heat with gas or propane: heat pump rebates covering ground-source, air-source and ductless systems, an AC rebate, a reduced heating rate for heat pumps with an automatic backup, and Wi-Fi PowerNap for air conditioning. Ask us which rebates apply when we quote. Rebate programs change every year, so check the utility's current terms before you buy.

At a changeover temperature we set, based on what propane and electricity cost you and how much heat the heat pump still makes in the cold. Many cold-climate models keep heating below zero, with less output as the temperature falls. On Connexus Energy's lower heating rate, the co-op may also hand the heating load to the furnace when demand peaks, so the furnace and tank still have to be ready all winter.
Quieter than the old one, if it's picked with that in mind. Two-stage and variable-speed condensers run on low speed for most of the season, and many carry a sound blanket on the compressor. Placement matters just as much: we set the unit away from bedroom windows and sound-bouncing corners, while holding the manufacturer's clearances. Compare the published sound ratings when you look at quotes.
