Ductless Mini-Split Installation in Idaho Falls, ID
A ductless mini-split heats and cools a space from one small wall unit, with no ductwork to run. We install, repair, and maintain single-zone and multi-zone mini-splits across Idaho Falls and Bonneville County, for garages, additions, shops, and homes that were never set up for central air. Because it’s a heat pump, one system covers both seasons, and ductless heat pumps qualify for a local rebate we handle for you. Want the whole house done through ducts instead?

Ductless Heat and Cooling Without Ductwork
A mini-split is two pieces: a compact unit outside and a slim head on the wall inside, joined by a small refrigerant line through the wall. No ducts, no big remodel. It’s a heat pump, so it cools in summer and heats in winter from the same system.
That makes it the answer for spaces central air can’t reach easily. A garage, a bonus room over the garage, an addition, a shop, or an older home with no ductwork at all. We size it, install it, and service it, and we’ll tell you honestly when a mini-split is the right tool and when central air makes more sense.
One Small Unit, |Two Seasons|
When Ductless Heating and Cooling Makes Sense
Is a Mini-Split |Right for the Space?|
A garage or shop you want comfortable
A mini-split conditions a garage or shop without tying into the house system, so you can work out there in July and January both.
An addition or converted room
Bonus rooms, sunrooms, and additions rarely have ducts run to them. A single head heats and cools the space on its own.
One room that's always off
If the upstairs bedroom bakes or the back room never warms up, a mini-split fixes that one zone without touching the rest of the house.
A home with no ductwork
Older homes on baseboard or wall heat can add real heating and cooling without the cost and mess of installing ducts.
Single-Zone and Multi-Zone Mini-Split Options
Single Zone to |Whole House|
Single-zone
One outdoor unit, one indoor head. The simplest, most affordable setup for a garage, an addition, or a single room.
Multi-zone
Several indoor heads run off one outdoor unit, each with its own control, so you can condition multiple rooms independently.
Cold-climate mini-split heat pump
The models we install keep heating below 5°F, tested and certified to do so (ENERGY STAR). That matters for a winter like ours.
Repair and maintenance
Already have a mini-split? We repair the common faults and keep the filters and coils clean, so it maintains efficiency.
Benefits of a Ductless Mini-Split
Efficient, Quiet, and |Rebate-Ready|
No duct losses
Ducts lose energy to leaks and long attic runs. A mini-split delivers heating and cooling straight into the room, so less of what you pay for goes to waste.
Rebate and loan eligible
Ductless heat pumps qualify for an Idaho Falls Power rebate, or a zero-interest loan up to $10,000 in place of it, for customers who qualify (Idaho Falls Power). See what’s current on our special offers.
Quiet and zoned
The indoor heads run quietly, and each zone sets its own temperature. Some people picture a bulky box, but today’s low-profile heads are slim, and you’re not heating rooms nobody’s in.
Sized, Mounted, |and Charged|
What a Mini-Split Installation Includes
We start by sizing the system to the space, because BTUs matter more than square footage alone. A single 12,000 BTU head suits one average room, while a garage or a multi-room job needs the math done right. Undersize it and it can’t keep up, oversize it and it short-cycles.
On install day we mount the indoor head, set the outdoor unit, run and charge the refrigerant lines through a small wall penetration, and test it in both heating and cooling before we leave. A mini-split heats and cools the zone it’s in, not the whole house, so if you want every room covered, we’ll plan the heads for that. Installed cost depends on single versus multi-zone and the size, and it goes in your written quote.

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!

Mini-Split |Questions|
Idaho Falls Ductless Mini-Split FAQs
How much does a ductless mini-split cost?
It depends on whether it’s single-zone or multi-zone and the size of the space it needs. You’ll get a written quote, and between financing and the local ductless rebate, the upfront number is often lower than people expect.
Do mini-splits heat well in our winters?
Yes, with a cold-climate model. The ones we install keep producing heat well below freezing, and for a space that needs a backup, we’ll talk through the options. You won’t be left cold in January.
Mini-split or central air, which is better?
Central air cools the whole house through ducts you already have. Ductless is the better call for spaces with no ducts, single rooms, additions, and garages, and it heats too. We’ll tell you which fits your situation.
How many BTUs do I need?
It comes from the room’s size, its use, the insulation, and the windows, not a rough guess. We measure and size it so the head isn’t fighting the space or short-cycling.
Do you repair and maintain mini-splits too?
Yes. We install new systems, repair existing ones, and handle the filter and coil cleaning that keeps a mini-split running efficiently. Same crew either way.

We File Your Ductless Heat Pump Rebate for You
Rebates are the thing homeowners ask us about most, and they’re where the money quietly slips away, usually in the paperwork. So we handle it. A ductless mini-split is a heat pump, which means it qualifies for the Idaho Falls Power rebate or the zero-interest loan, and the utility needs the contractor to file the application. You send us the form, we fill in the details, submit it, and follow it through. You sign, you cash.
