Imagine waking up after a fresh snowfall to a driveway that’s already clear.
No shoveling. No icy sidewalks. No scrambling to spread salt before guests arrive. Just safe, dry walkways and a driveway that’s ready when you are.
One of the most common questions homeowners ask is, “Should I repair my HVAC system, or is it time to replace it?”
The answer isn’t always straightforward—and it shouldn’t be.
When you see a beautifully crafted copper range hood, a perfectly fitted chimney cap, or custom architectural metalwork on a home, it’s easy to admire the finished product. What you don’t always see is the craftsmanship behind it.
When most people think about gutters, they think about function. Gutters move rainwater away from your home, protect your foundation, and help prevent water damage. They’re essential—but they don’t have to be ordinary.
Beautiful Metalwork Designed to Be Seen
Most people never think about sheet metal.
It’s hidden behind walls, above ceilings, and inside mechanical rooms, quietly doing its job every day.
But at Thornton Heating & Sheetmetal, some of our favorite projects are the ones you actually get to see.
For more than 50 years, we’ve been fabricating custom sheet metal that goes far beyond HVAC ductwork. From stunning copper range hoods and handcrafted backsplashes to architectural accents, countertops, and decorative metal finishes, we create one-of-a-kind pieces that become the focal point of your home.
Beautiful craftsmanship. Exceptional function. Built right here in the Wood River Valley.
Keep Your Business Comfortable with Expert Commercial Heating Solutions
When temperatures drop across the Wood River Valley, dependable commercial heating isn’t just about comfort—it’s essential to keeping your business operating. Whether you manage an office building, retail store, restaurant, medical facility, school, or industrial space, your heating system plays a critical role in protecting employees, customers, equipment, and daily operations.
Every home has its own personality. From the architectural style and finishes to the smallest design details, no two homes are exactly alike. That’s why custom sheet metal is one of the best ways to create a home that’s truly your own.
Walk into the sheet metal shop at Thornton Heating & Sheetmetal, and you’ll quickly realize that custom fabrication is more than a service—it’s a craft that’s been refined for more than 50 years.
