A central air replacement in an Arlington rambler runs $5,200–$9,800 installed with us, sized by Manual J. Many ramblers here have a single central return, which limits how much AC the ducts can carry.
Sizing an air conditioner for an Arlington house starts with the ducts, because many were designed for heat alone. A single central return can only move so much air, and a condenser sized by square footage can outrun it, leaving a cold, wet coil and clammy rooms. We run a Manual J for the house and measure static pressure on the ducts, then size the AC to what both can support. Sometimes a second return belongs in the same quote.
The rest is ordinary work done carefully: a new indoor coil matched to the R-454B or R-32 outdoor unit, the line set checked or replaced, the condenser set level on its pad with its own disconnect. For farm homes on propane, a heat pump in place of a plain AC adds spring and fall heat and cuts LP use. Electric programs come from the city's utility, which buys its power through the Minnesota Municipal Power Agency.

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.
Electric-side rebates come from the city, through MMPA member programs that list rebates for air-source heat pumps and central air conditioners. Ask us which rebates apply when we quote. Rebate programs change every year, so check the utility's current terms before you buy.

Often, yes. The heat pump cools in summer like any AC, then heats through spring, fall and milder winter days, which is where it saves propane. The propane furnace stays as backup for deep cold, since heat pump output drops as temperatures fall. That dual-fuel pairing suits farmhouses with existing ducts. We install heat pumps for $7,500–$14,500. Check your electric provider's heat pump programs before you buy.
It can if the unit is bigger than the ducts can serve. One central return limits the air crossing the coil, and too little air lets the coil run cold enough to ice while the registers get noisy. Before we quote, we measure static pressure on the existing ducts and size the AC to what they can carry. When the return is the limit, adding a second return at the bedroom end goes in the written quote as its own line.
