Unit Heaters
Sterling® Unit Heater
Your garage can be a comfortable, fully functional extension of your living space. Whether you use your garage for projects, storage, vehicle maintenance, or workouts, consistent heat protects your investment and keeps you productive and comfortable.
Year-Round Functionality
When temperatures drop, a heated garage allows you to continue woodworking, automotive work, fitness training, or hobby activities even in the middle of winter.
Protect Your Vehicles & Equipment
Freezing temperatures can cause serious wear and tear. A temperature-controlled garage helps:
- Prevent battery drain and cold-start engine stress
- Reduce oil thickening and fluid freezing
- Protect power tools and equipment from moisture damage
- Extend the lifespan of stored items
Improve Safety & Structural Protection
Cold garages can lead to condensation buildup and slippery conditions. Heating your space helps maintain stable conditions, reducing the risk of damage and hazardous working environments.
Increase Home Appeal & Value
A heated garage adds practical square footage to your home. Buyers see it as a premium upgrade, especially in Montana's colder climate, which makes your home more competitive on the market.

Propane & Natural Gas Heaters
Fuel-based heaters deliver fast powerful heat output. These systems are well-suited for drafty spaces and high ceilings but require proper ventilation and professional installation.
