Upgrading the heat or adding AC in your Shoreline home? From Richmond Beach to North City, we install furnaces, heat pumps and AC with clear pricing, permits handled and a crew that treats your home with care.
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 Shoreline last 15 to 20 years. Past that, breakdowns and wasted energy pick up fast.
Two or three repair calls in a year is a pattern, not bad luck. At some point, those bills are better spent on a new system.
If your bills keep climbing while your habits stay the same, worn-out equipment is often the reason. New high-efficiency systems use less energy.
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.
Summer heat waves are tough without AC. Central air or a heat pump keeps every room comfortable when it counts.
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: the go-to setup for Shoreline homes with natural gas. You get strong, fast heat on cold mornings and central cooling for summer.
Heat pump: all-electric heating and cooling in one system. A Mitsubishi Hyper-Heat keeps full heating output down to 5°F, and Seattle City Light customers can check its programs for heat pump support.
No ductwork? A ductless mini-split heats and cools room by room. It’s a smart fix for older homes heated with baseboards or wall heaters.

For most Shoreline homes, a new furnace runs about $5,000 to $10,000 installed, a furnace with central AC about $11,000 to $17,000, and a Mitsubishi Hyper-Heat system from around $16,000, all before sales tax. The calculator above narrows it down for your home.
Usually not. Most furnace and AC swaps are done in a single day, so the heat is back on that evening. Bigger jobs like a new heat pump, ductwork or an electrical circuit can add a day, and we’ll tell you before we start.
Shoreline has a lot of mid-century homes, where switching to a heat pump or adding central AC is a common upgrade. 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.
Age, repair costs and safety are the big three. A system past 15 years, a repair near half the cost of a new unit or a cracked heat exchanger usually points to replacement. If a repair will do the job, we’ll say so.
