Millwood · cooling for mill-era houses
AC and heat pump installation in Millwood, panel work quoted up front
Millwood’s mill-era houses were built around a basement furnace and windows that open. Adding cooling, or retiring a tired 1990s condenser, usually means a new circuit and panel work — and that part goes on the same written quote.

The houses that give Millwood its character — built from the 1920s into the 1940s for Inland Empire Paper mill families along Marguerite, Dalton and the streets sloping down toward the river — were designed for a basement furnace and windows thrown open on summer evenings. Many still have no central cooling. Others carry an add-on condenser bolted on when the furnace was replaced about twenty-five years ago, now on R-22 and running out of summers. Either way, an install here is half mechanical and half electrical: where the condenser will sit, how the copper reaches the coil in the basement, and whether the panel has the room and the capacity for a 240-volt circuit.
That last question is where most quotes come apart. A 1940s panel, or a first upgrade from the 1970s, often has no spare slots and sometimes too little service for a compressor. We check that on the site visit, and the panel, circuit and disconnect go onto the written quote as their own line items, with the permit, so the cost is settled before you sign. The install site visit costs nothing, whether or not you go ahead.
Common Millwood starting points
| Situation | What we usually recommend | Why |
|---|---|---|
| No cooling at all, a window unit hauled up each June | Central air added to the basement furnace, sized room by room | Old plaster walls hold the day’s heat past midnight, and one window unit cannot chase it |
| 1990s add-on condenser on R-22 | New R-454B system with a matching indoor coil | The refrigerant is scarce and the July repair bills keep growing |
| Gas furnace near the end of its life as well | New furnace paired with a cold-climate heat pump as dual-fuel | Doing both at once avoids two installs and two aging systems |
| Original panel or a 1960s replacement, every slot used | New panel or added capacity, listed as its own line on the quote | This is the step where most Millwood quotes go quiet for weeks |
| All-electric house, no gas line on the block | Cold-climate heat pump that relegates the electric heat to emergencies | Resistance heat costs far more per hour than a heat pump making the same warmth |
| Plaster walls and original ductwork | Duct inspection alongside the load calculation | Old ducts decide how much air the new system can actually deliver |
Cooling a mill-era house without fighting it
In Millwood the duct inspection carries as much weight as the load calculation. Plaster walls and original runs mean the new system has to work with what is already inside the house, so on the visit we trace and check each run, look at the furnace and its blower, and note insulation and windows. Too large a unit short-cycles and leaves rooms clammy; too small a unit labors all afternoon in August. The Manual J — the real calculation, not a square-footage rule — sets the size, and the ducts tell us whether the house can use it.
Outside, the condenser goes on a pad or stand where snow and roof runoff will not bury it, with the shortest sensible run to the basement coil. Inside, the copper is brazed, pressure-tested with nitrogen and evacuated before a single ounce of refrigerant is released, then the charge is weighed in and checked on gauges by technicians who hold EPA 608 Universal certification. The circuit, disconnect and any panel work are itemized on the quote, and we book the inspection rather than handing that chore to you. Most changeouts take a day; new copper, a coil and panel work make it two.
If the furnace will need replacing within a few years anyway, ask about pairing it with a cold-climate heat pump. Running as dual-fuel, the heat pump carries most of the winter and the furnace handles the coldest nights — the most economical heat available for a house like this. We price that option beside a straight AC so the two numbers sit next to each other on paper. Equipment comes from Goodman, Carrier, Daikin, Bryant, Fujitsu or Mitsubishi, in whichever tier the house and budget call for.
Where Millwood install prices begin
Eight decades or more have made every Millwood house its own case, so read these only as a starting point. Within the Spokane area, central AC on an existing furnace starts at $4,150, an inverter cold-climate heat pump at $4,900, and a 95% gas furnace, if it is being replaced alongside, at $5,500 — the equipment comes inside each figure along with the install. They are area starting prices, not your quote. Panel work and the route the copper takes to the basement are the usual reasons a figure climbs, and yours arrives in writing after the no-cost visit with a cash and a financed column. Utility rebates are checked for your address, and if the visit was booked online, up to $500 comes off a full-system install with its first-year tune-up included.
| System, installed | Price |
|---|---|
| Central air conditioner | from $4,150 |
| Inverter (variable-speed) heat pump | from $4,900 |
| Gas furnace, 95%+ AFUE | from $5,500 |
| Heat pump outdoor unit only | from $4,200 |
| Heat pump with air handler | from $5,750 |
| Ductless mini-split, single zone | from $3,350 |
| Each added mini-split zone | from $1,900 |
| Multi-zone mini-split systems | On request |
Starting prices with equipment and installation included, before utility rebates and before our up to $500 off a full system. Multi-zone systems are quoted on request. The site visit and written quote cost nothing.
Questions we hear
Can you add central AC to a Millwood house with an old panel?
Yes, and it is the install we do most often in Millwood. We evaluate the panel on the site visit, and any upgrade, the new circuit and the disconnect are listed as line items along with the permit. If the service itself needs to be larger, that appears as its own line in the written quote, so install day brings no surprises.
Does a heat pump make sense instead of plain AC?
In a lot of Millwood houses, yes. The same outdoor unit that cools in July runs in reverse from fall to spring, and the furnace only wakes up on the bitter nights. For a house heated by gas that means a lower winter bill; for one heated by electric strips it means a much lower one. We put the heat pump price and the plain-AC price on the same quote so you can weigh them.
How long does the install take, and who pulls the permit?
A straight changeout is one day; new copper, a coil, electrical and panel work make it two. We pull the permits and schedule the inspection. The timeline is written into the quote, so you know the dates before you sign anything or move a single box out of the basement.
What happens during the site visit?
Roughly an hour of measuring: rooms, ductwork, insulation, the furnace and blower, the panel, and the route for the condenser and line set. Afterward you receive a written, itemized quote that is good for thirty days. There is no charge for the visit, and no deposit until you approve the work and we order the equipment.
Are there rebates for Millwood homeowners?
Sometimes, and the details move every year. We look up which utility programs cover your address at the time of the quote rather than relying on last season’s list, steer toward qualifying equipment when it suits the house anyway, and complete the paperwork with you ahead of install day. Separately, a visit booked online takes up to $500 off a full system.
Call, text or book
Pick up the phone, send a text, or fill in the online form — the form is the route to up to $500 off a full system. If the old condenser is worth saving for now, its repair starts with the $99 diagnostic, which then becomes part of the repair price rather than a separate charge.
