HVAC Contractor in Firth, ID
Firth is a small river town between Shelley and Blackfoot, and whether you’re in town on a natural-gas line or out on a farm running propane changes the smart heating choice completely. We work both sides of that line, and the first thing we do is figure out which one you’re on before recommending anything.

A Swedish River Town With |Two Fuel Realities|
Gas and Propane Heating in Firth, Bingham County
Firth began as a Swedish settlement in 1885 on the east bank of the Snake, looking across at the Blackfoot Mountains. Homes in town along State Street generally have Intermountain Gas, while the farms out from the center run propane, and that split is the whole ballgame for a new system. Everyone here is on Rocky Mountain Power, so a heat-pump rebate runs through Wattsmart either way.

Gas or Propane, |What Fits?|
The Questions We Get in Firth
In-town home on natural gas, best heat? Usually a high-efficiency gas furnace. It’s the cheapest to run on the Firth mains, and we won’t upsell past it.
Farm on propane, best heat? A heat pump or dual-fuel often wins. Propane’s expensive, so the pump carries the mild days and cuts what you burn.
Adding a shop out on the farm? We match the heater to your propane supply and the building, and run the line if it needs one.

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!

Huter did a great job. Very knowledgeable and professional. Obviously knows his business very well. He pinpointed the problem in minutes and had it resolved in just a few more minutes. I would recommend them to anyone.

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!

Firth |Questions|
HVAC FAQs for Firth Homeowners
How do I know if I'm on natural gas or propane in Firth?
If you have a tank on the property, it’s propane; if there’s a gas meter fed from the street, it’s Intermountain Gas. We check for you and recommend accordingly.
My propane bills are high. What can I do?
On propane, a heat pump or dual-fuel setup usually cuts the bill the most. Sealing ducts helps too. We’ll run the numbers for your place.
Which rebate applies here?
Firth is Rocky Mountain Power, so the Wattsmart program. We confirm by address and file it.
Is Firth close enough for regular service?
Yes, a short run between Shelley and Blackfoot, no travel premium.
Can you handle the house and a farm shop in one trip?
Yes, same crew for both.
