HVAC Contractor in Iona, ID
Iona is one of the oldest settlements east of Idaho Falls and one of the fastest-growing, which puts century-old homes and brand-new builds on the same street. The old ones often still run leaky, undersized ductwork; the new ones need a system designed in from the start. We handle both, and we’ll tell you honestly which side of that line your house is on.

A Town That Kept Its History
Furnace, AC, and Duct Sealing in Iona
Iona was settled in 1883 as Sand Creek, and the 1887 Meetinghouse at Main and Rockwood still stands on the National Register. Homes from that early era sit near the old townsite, and they tend to share a problem: original or patched-in ductwork that leaks a fifth to a third of the air before it reaches the room. Meanwhile, the town has more than doubled, so new subdivisions on the edges need load calcs and balanced duct design, not a hand-me-down approach. Iona’s on Intermountain Gas and Rocky Mountain Power, so natural gas is the common heat, and a heat-pump rebate runs through Wattsmart.

We had an outstanding experience with Ridgeline Heating and Cooling! From start to finish, they were incredibly responsive, professional, and easy to work with. The quality of their service was top-notch, and their pricing was extremely fair—especially compared to other companies in the area, who quoted us nearly double with half the communication.
Ridgeline went above and beyond by helping us look into the warranty on our new system, which really showed they care about their customers, not just the sale. It’s rare to find a company that combines great service, fair pricing, and clear communication, but Ridgeline nailed it.
Very impressed and will absolutely be using them again in the future!

I called for help with a broken down heater on a cold morning and Hunter was there within the hour! His service was fast, efficient, and he communicated clearly the issue and what needed to be done to fix it. He was also very upfront about the cost and it was very reasonable. I also spoke with Bridger Harris and was extremely impressed with how he looked out for us and made sure we were taken care of. I highly recommend Ridgeline Heating and Cooling!

I had Mike and Anthony install my air conditioner. They did a great job, they were very efficient, explained everything, cleaned up all the trash. Ridge got right back to me with a bid and I was able to have it installed in a week. Would highly recommend

Iona |Questions|
HVAC FAQs for Iona Homeowners
My historic Iona home has hot and cold rooms. New furnace?
Usually not first. In an older home, it’s the ductwork leaking and unbalanced, and a bigger furnace just pushes more air through the same leaks. Sealing and balancing is the cheaper, longer fix, and we test to prove it worked.
Can you put modern heating in a century-old house without tearing it up?
Often, yes. Aeroseal seals from inside the ducts with no drywall damage, and a right-sized high-efficiency furnace drops into the existing setup once the ducts are tight.
Is Iona a normal service area for you?
Yes, a short run from the shop with no travel premium.
New build in Iona, what should I ask for?
A load calc and a duct design, not a system sized off square footage. That’s what keeps a new home even from day one.
Will sealing my historic home's ducts damage the walls?
No. Aeroseal works from inside the ducts, so there’s no drywall or plaster damage in an older Iona home, which is exactly why it’s the right tool for the historic houses here.
