A snowmelt system runs warm hydronic lines beneath your driveway, patios, and walkways to melt snow as it falls. October is the last good stretch to get one installed before the first storm, while the schedule is still open. Next winter, you'll watch the snow disappear on its own.

Beat winter before it starts.

Most countertops come in a box. Ours come from our shop. We fabricate custom metal countertops in stainless steel and copper, cut and formed to fit your space exactly. Steel brings clean, durable strength. Copper brings warmth and a living patina that deepens with age. Either way, it's a surface built to be used and to stand out.

Function you'll use. Craft you'll show off.

There's nothing like stepping onto a warm floor on a frosty valley morning.

Radiant floor heat delivers even, quiet warmth that rises from the ground up, no blowing air, no cold spots. If you're planning a remodel or new space this fall, it's the ideal time to design radiant heat in from the start. We build these systems for the way Idaho winters actually feel.

Comfort you feel underfoot.

This is the shop. Steel and copper getting measured, cut, and formed by hand into the ductwork, hoods, and finishes we install. Everything we make starts here, one piece at a time.
Made by hand, in-house.

Everything we make, we make in-house: custom hoods, countertops, chimney caps, gutters, and finishes, cut and formed to fit your home exactly. Steel for clean, durable strength. Copper for warmth and a patina that deepens over the years.

Built to fit. Made to last.

As the house closes up for winter, here's one job that's easy to forget: your dryer vent.

A clogged vent runs hotter, dries slower, and becomes a real fire risk, exactly when your dryer is working overtime through the cold months. We install and service custom dryer venting, sized and routed to move air the right way. Small job, serious peace of mind.
A safer home starts with the details.

There's a particular kind of quiet in a home that's warm before you even feel cold.

Heating season is here, and hydronic systems and boilers carry the load all winter long in the valley. We service, repair, and tune boiler and hydronic systems now, so the heat is steady, even, and quiet when the temperature drops. And true to how we work, you will not see or hear your system.

Quiet warmth, all winter.

Fall is the last easy window before you actually need your heat every night.

Now is the time to get your furnace checked before the first cold snap turns a small issue into a no-heat night. As your local Carrier dealer, we service and tune furnaces so they run safe, efficient, and ready for the coldest Sun Valley nights ahead.
Warm now beats waiting later.

Most ductwork is mass-produced to fit a house that doesn't exist: the "average" one.
We do it differently. Every piece of sheet metal we fabricate is measured to your actual space, cut in our own shop, and formed to fit exactly, no gaps, no forcing, no "close enough." That precision is why your system runs quieter, moves air better, and lasts longer. It's the difference between metal that's installed and metal that's crafted.

Precision you'll never see, comfort you'll always feel.
