HVAC Contractor in St. Anthony, ID
St. Anthony is the Fremont County seat, high on the Henry’s Fork near the sand dunes at almost 5,000 feet. It’s one of the last towns heading north with natural-gas mains in town, so a gas furnace is still the cheap default here, even though the winters are long enough that heating is the whole job.

Furnace, Fireplace, and AC Service in St. Anthony
St. Anthony was established in 1888, and its courthouse and post office are both on the National Register. It has Intermountain Gas in town, which keeps a gas furnace the cheapest heat, but it’s served by Fall River Electric Cooperative, not Rocky Mountain Power or Idaho Falls Power, so a heat-pump rebate here runs through Fall River’s program. At nearly 5,000 feet, the heating load is serious, so sizing matters more than in the valley.

The Questions We Get Here
Should I stick with a gas furnace? In town, usually yes; the gas mains make it the cheapest heat. We won’t push you past it.
What rebate do I get if I go with a heat pump? Fall River Electric’s program, not Idaho Falls Power’s. We confirm and file it.
Is a fireplace worth it up here? Often, yes, for backup heat. A gas fireplace keeps a room warm through the outages a long winter brings.

One Job at a Time
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

St. Anthony |Questions|
HVAC FAQs for St. Anthony Homeowners
Does St. Anthony have natural gas?
In town, yes, Intermountain Gas, which keeps a gas furnace the cheapest heat. Out from town, you may be on propane, and we’ll tell you which changes the math.
Which heat-pump rebate applies here?
St. Anthony is on Fall River Electric, so it’s their program, not Idaho Falls Power’s. We confirm by address and handle it.
Does the cold up here change what furnace I need?
Yes. At nearly 5,000 feet, the heating load is high, so we size for the deep freeze, not a valley-floor average.
Can a fireplace give me backup heat in an outage?
A gas fireplace with a standing pilot will, which is worth having through a St. Anthony winter.
Is St. Anthony on your regular route?
Yes, part of our Fremont County coverage up the valley.
