Planning a new furnace, AC or heat pump for your Woodinville home? From Hollywood Hill to Cottage Lake, we install systems sized for larger homes and properties, with upfront pricing and a team that stays with you after install day.








Not every old system needs replacing, but these signs usually mean it’s time to start planning before it fails on a cold night.
Most furnaces and AC units around Woodinville last 15 to 20 years. Past that, breakdowns and wasted energy pick up fast.
When repair bills start stacking up, or one repair costs close to half of a new system, your money usually goes further on a replacement.
A tired furnace or AC runs longer to do the same job, and your utility bill shows it. Newer equipment does more with less.
Cold bedrooms, a system that runs nonstop or one that can’t keep up can mean it’s worn out or was never sized right.
A crack lets combustion gases mix with the air you breathe. If we find one during a visit, we’ll show you and talk through safe options.
Hot summer days are rough without AC. Adding central air or a heat pump keeps the whole house cool.
Repair is always our first move. If a fix will keep your system running safely for years, we’ll tell you that before we ever quote a replacement.
Gas furnace and central AC: a proven pairing for Woodinville homes on natural gas. Quick, powerful heat in winter and whole-house cooling when summer heats up.
Heat pump: all-electric heating and cooling in one system. A Mitsubishi Hyper-Heat keeps full heating output down to 5°F, so it heats large homes on acreage without a backup furnace.
No ductwork? A ductless mini-split heats and cools room by room. It’s a clean way to handle a guest suite, shop or bonus room without new ducts.

It depends on the equipment and your home. As a guide, furnace replacements run about $5,000 to $10,000, furnace and central AC systems about $11,000 to $17,000, and Mitsubishi Hyper-Heat systems from around $16,000, before sales tax. Try the calculator above for your home.
A straight furnace or AC replacement is typically a one-day job. Heat pump installs, ductwork changes or a new electrical circuit can stretch it to a second day, and we’ll let you know when we quote it.
Woodinville has many larger homes and properties on acreage, where one system may not cover the whole house evenly. We do a load calculation at your home instead of matching the old unit, so the new system heats and cools evenly without short cycling.
If your system is over 15 years old, needs frequent repairs, has a cracked heat exchanger or can’t keep the house comfortable, replacing usually makes more sense. If a repair is the smarter move, we’ll tell you that too.
