Unit Heater Installation & Repair in Helena, MT

Heating Montana's Workspaces

In Montana, a garage or shop isn't just storage—it's a workspace, a hobby center, or a necessary shelter for vehicles and equipment during harsh winters. Suspended unit heaters (often called Modines, regardless of brand) are the most effective way to heat these large, open spaces, keeping you comfortable and your engines warm.

Around Helena, the demand for shop heat is real and specific. Diesel pickups need a warm bay to start reliably in January. Well pressure tanks and water lines in attached garages need protection from hard freezes. Home mechanics, woodworkers, and welders want a space they can actually use through the five cold months instead of abandoning it from Thanksgiving to April. A properly sized and installed unit heater turns a dead-of-winter storage box back into usable square footage — often for less money than homeowners expect.

Sizing is where most DIY installs go wrong. The right BTU rating depends on the cube of the space (not just the floor area — a 12-foot ceiling changes everything), the insulation levels in the walls and ceiling, how big and how leaky the overhead doors are, and how quickly you want the space to recover after a door has been open. An oversized heater short-cycles and leaves cold corners; an undersized one runs constantly and never catches up on the coldest days. We run the numbers before we quote a single piece of equipment.

Why Choose a Unit Heater?

• Space Saving: Mounted to the ceiling or wall, they free up valuable floor space.

• Quick Recovery: They blast warm air to rapidly heat the space after a large overhead door is opened.

• Durable: Built for dusty, industrial, and agricultural environments.

• Safe: Designed with proper venting to keep exhaust gases out of your workspace.

Our Process

1. 1

   Assess: We evaluate your space's square footage, insulation, and ceiling height to size the unit correctly.

2. 2

   Explain: We discuss fuel options (natural gas vs. propane) and venting requirements.

3. 3

   Quote: A clear, complete price covering the heater, gas line, and venting.

4. 4

   Install: We securely mount the unit, run the gas piping safely, and install code-compliant exhaust venting.

5. 5

   Walk-through: We test the system and demonstrate the thermostat controls.

6. 6

   Warranty: Guaranteed workmanship.

What We Work On

We install, service, and repair natural gas and propane unit heaters for residential garages, agricultural barns, and commercial shops, including units from Modine. For spaces where a forced-air unit isn't the right fit — dusty woodshops where a fan stirs up debris, or bays where radiant warmth on the floor matters more than air temperature — we can also install gas-fired infrared tube heaters, which warm objects and people directly rather than the air.

Every installation includes the full scope: mounting the unit from the structure with proper hangers, running code-compliant gas piping from your meter or propane tank, installing sealed venting through the roof or sidewall, and wiring the thermostat where you actually work. If you have an existing heater that's limping — igniter clicking without lighting, fan running without heat, or a unit that trips out on windy days — we diagnose and repair those too, usually in a single visit.
