New Construction HVAC in Idaho Falls, ID
Builders need an HVAC partner who reads plans, hits the schedule, and roughs in clean. We design and install heating and cooling for new construction across Idaho Falls and Bonneville County, from custom homes and spec builds to multi-family. That means load calcs, duct design, and rough-ins done right the first time, plus a project manager who keeps our part on your timeline. If you’re pricing a build, request a bid, and we’ll turn your plans into a system that works on day one.
Tell us what’s going on. We’ll get you on the schedule and take it from there.

HVAC for Custom, Spec, and Multi-Family Builds
A good HVAC sub does more than drop in equipment. They read the plans, coordinate with the other trades, hit the rough-in date, and hand off a system that’s sized and balanced for the home. That’s the part builders remember on the next job.
We work on custom homes, spec builds, additions, and multi-family across the valley. Our owner, Bridger, turns blueprints and mechanical plans into working systems, Ashton runs the schedule and the permits so our part lands on time, and Nick fabricates custom duct in-house when a run calls for it. Three owners who each own a piece of getting your build done right.
An HVAC Partner Builders Can Plan Around
New Construction HVAC for Every Build
What Are You| Building?|
Custom homes
Every custom home is its own puzzle. We design the system around the actual floor plan, not a template, including zoning and in-floor heat where they fit.
Spec homes
For spec builds, we deliver a clean, efficient, right-sized system that shows well and holds up, on a schedule and a bid you can plan around.
Multi-family and apartments
Multi-unit work has its own rhythm. We handle the repetition and the coordination that keeps a multi-family build moving.
Additions and major remodels
Bumping out or building up means tying new load into an existing system or adding capacity. We design that so the whole house still balances.
Load Calcs, Duct Design, and Rough-In
From Load Calc| to Rough-In|
Load calculation
We size the system off a real Manual J load calc, not square footage. That’s what keeps a new home from having a cold room the day the owner moves in.
Duct design
We design the duct layout for balanced airflow to every room, built in before the walls close instead of fixed with callbacks later.
Clean rough-in
We rough in coordinated with framing, electrical, and plumbing, so our work fits the space and doesn’t hold up the next trade.
System selection
Furnace, heat pump, AC, radiant floor heat, and zoning all get chosen and designed in at the plan stage, when it’s cheapest to do right.
Why Builders Choose Ridgeline
On Your Plans and| On Your Schedule|
We read the blueprints
Bridger turns mechanical plans and schematics into installed systems, so you’re not walking us through the drawings.
We hit the schedule
Ashton runs our scheduling and permitting, so the rough-in and the trim land when your build needs them, not whenever we get to it.
Custom duct in-house
Nick fabricates sheet-metal duct himself, so an odd run doesn’t mean waiting on a shelf part or a shop across town.
Built Right Before the |Drywall|
What Our New Construction HVAC Includes
We start with a plan review and a Manual J load calc, then design the system, the ductwork, and any zoning or in-floor heat the build calls for. We rough in on schedule, coordinated with the other trades, then install, start up, and test the finished system.
The homebuyer gets our first-year warranty on the equipment we install, which is something a builder can point to at closing. Bids come from your plans, so request a bid, and we’ll price it off what you’re actually building.

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!

Builder| Questions|
Idaho Falls New Construction HVAC FAQs
Do you provide bids for builders?
Yes. Send us the plans, and we’ll bid the HVAC scope off them, so the number reflects the actual build. Request a bid, and we’ll get started.
Do you handle multi-family and apartments?
Yes. We take on multi-family and apartment work along with custom and spec homes, and we’re set up for the coordination that kind of build needs.
What's included in a rough-in?
The ductwork, line sets, venting, and equipment prep that go in before drywall, coordinated with framing, electrical, and plumbing so nothing has to be torn back out.
Can buyers pick their own equipment or fireplace?
Yes, and that’s where our showroom helps. Buyers can see equipment and fireplaces running in person and choose what goes in their home before it’s installed.
Do you do the load calcs and duct design, or just install?
The full design. We run the Manual J load calc and design the duct system, then install it. Sizing off a real calc is what separates a comfortable new home from one with a room that never gets warm.

The Ridgeline |Showroom|
Your Buyers See It Before It Goes In the Home
A lot of people pick a fireplace or a system off a spec sheet and don’t love it until it’s already installed. On a custom build, that’s an expensive change order. Our showroom fixes it. Your buyers can stand in front of real fireplaces, gas and electric, every one live and running, set inside finished living rooms, and choose what goes in their home before it’s built in. It’s the only showroom in the region where every unit is operational, staged in a real living space, from a licensed HVAC contractor who also installs it.
