AC Installation in Millwood
We size a new air conditioner to your home, give you a written quote before any work begins, and install it with your floors covered and your yard treated with care. You know what's happening at every step, and the estimate costs nothing.
A new air conditioner, put in the right way
A new AC is a big purchase, and most of how well it works comes down to the install. An oversized unit cycles on and off and leaves the air clammy. An undersized one runs all afternoon and still can't keep up. We start by working out what your home actually needs, then recommend equipment that fits it and your budget.
We also treat your home like it matters, because it does. Our crew lays down floor runners and drop cloths, wears shoe covers indoors, and keeps tools and old equipment off your lawn and garden beds. Before we start and before we leave, we tell you what we did and what comes next.
If your home has no ducts, ductless mini-splits may be the better fit. If you want heating and cooling from one system, ask us about heat pumps.
The work behind a new air conditioner
- Load calculation first
- Before we recommend a size, we measure the rooms, check attic insulation, count windows and note which sides of the house bake in the afternoon. The old unit's nameplate is a starting clue, not the answer.
- Old condenser recovered and hauled off
- Refrigerant in the old system is pulled out with recovery equipment, never vented. We load the retired unit onto our truck so nothing is left sitting beside your house.
- Condenser pad and line set
- The new outdoor unit sits level on a pad, with room around it for airflow and future service. Fresh refrigerant lines are run, brazed and sealed, then fastened tidily along the siding.
- Coil matched to your furnace
- Central air uses your furnace blower to push cool air through the house, so the indoor coil has to match it. We confirm the blower moves enough air, and our Gas heating mechanical license lets us handle the gas furnace safely while we make the connection.
- Disconnect, permit and first startup
- An outdoor electrical disconnect goes in near the condenser. We pull the permit and arrange the inspection, then charge the system, measure temperatures and airflow, and program your thermostat.
Signs it's time for a new AC
The repair bills add up
When you're paying for AC repair a second time in one summer, or the quote is for a new compressor, putting that money toward a new system is often smarter. We'll tell you plainly which way we'd go and why.
The system is well past its prime
Most central air conditioners give their best years early. An older unit that still runs may be using far more power than a new one to do the same job.
Rooms that never cool down
Upstairs bedrooms that stay warm while the main floor is cold can point to an undersized unit. Longer runtimes without relief are a common clue.
An older refrigerant
Systems built around R-22 are expensive to recharge because that refrigerant is no longer made. A leak in one of these is usually the end of the road.
No central air at all
Plenty of homes still rely on window units and fans. During wildfire smoke season, when the windows need to stay shut, a whole-home system makes a real difference.
How your installation day goes
- 1
Free in-home estimate
We tour your home, check the furnace and the electrical panel, and ask how each floor feels on a hot afternoon. Before any work begins, you get a written quote that names the equipment and lists every part of the job.
- 2
Setting up and protecting your home
On install day we confirm the plan with you, lay runners from the door to the furnace, and cover the floor around the work area. Outside, we keep a clear path and protect plants near the condenser spot.
- 3
Swapping the equipment
We remove the old unit, set the new condenser and coil, and connect the lines and wiring. Most single-system jobs are done in one day.

Testing and walk-through
We start the system, check pressures and temperatures, and show you the thermostat and filter. We clean up, take our debris with us, and leave your home the way we found it.

What affects the cost of a new AC
Every home is a little different, so we price each installation after we've seen it. Your written quote lists the equipment and the labor so you can compare options side by side. The estimate is free on installations and replacements.
- Size and efficiency
- Larger capacity and higher efficiency ratings cost more up front. Higher efficiency can lower your summer power bills, and we'll explain where the extra spend pays back and where it doesn't.
- Your furnace
- If the furnace is old or its blower is too weak for a new coil, you may want to pair the AC with furnace installation. If the furnace is in good shape, we leave it alone.
- Electrical capacity
- Some panels need a new breaker or upgraded wiring to carry an air conditioner. We check this during the estimate so it isn't a surprise later.
- Condenser location and line length
- A longer run between the indoor coil and the outdoor unit, or a tight spot that's hard to reach, adds material and time.
AC installation questions
Something not covered here? (509) 516-1280
How long does an AC installation take?
Most replacements on a home with an existing furnace take one day. A first-time install, an electrical upgrade or a furnace swap at the same time can add time. We give you a realistic schedule in your quote.
What warranty comes with a new installation?
We cover up to 3 years labor on new installations. Equipment coverage comes from the manufacturer, and we'll walk you through what applies to the unit you choose.
Are you registered to do this work in Washington?
Yes. Our WA Contractor Registration is #KDHEAHA757JA, and we hold a Gas heating mechanical license, which matters when the new AC coil is connected to your gas furnace.
How do you protect my floors and yard?
We use floor runners, drop cloths and shoe covers inside, and we keep old equipment and tools off your lawn and beds outside. We clean up before we leave and tell you exactly what we did.
Should I get a heat pump instead of a central AC?
A heat pump cools your home just as well in summer, then reverses to supply heat in fall and spring, so your furnace runs less. Heat pumps can also qualify for Avista rebates and federal tax credits, and we'll handle the legwork of filing for them alongside you. Your quote can lay out both options so you can compare them before you decide.
