Heating & Cooling Systems Built for Duluth Winters

From Manual J calculations to final commissioning — every system custom-designed and owner-installed.

Service 01

High-Efficiency Gas Boilers & Hydronic Heat

High-efficiency boilers are our specialty. If you have a fuel oil boiler or an older inefficient unit, upgrading to a condensing gas or propane boiler can cut your fuel costs by 60% at current prices. Every system we install is sized with a computerized Manual J heat loss calculation to ensure you get the right boiler for your home.

  • Fuel oil to natural gas/propane conversions
  • High-efficiency condensing boiler installation
  • Hydronic system design and piping layouts
  • 60% lower operating cost vs. fuel oil

We design every infloor system in LoopCad with proper tubing layouts, manifold sizing, and heat output calculations.

  • New construction and retrofit installations
  • On-slab, above-subfloor, and below-subfloor options
  • Custom tubing layout designed in LoopCad

Panel Radiators & Hydronic Retrofits

If your home already has hydronic heat and you want to add comfort to a new room, an addition, or a cold zone, flat panel radiators are an elegant solution. We can also add zones (separate thermostats) to your existing boiler system so every area of your home is individually controlled.

  • Zone additions to existing boiler systems
  • Flat panel radiators and towel warmers
  • Solid European-quality construction
  • Clean, modern look that fits any interior

Furnaces & Air Conditioning

A high-efficiency furnace upgrade is one of the fastest ways to cut energy costs and increase comfort. If your home has forced-air ductwork, we can add central air conditioning for summer cooling. No ductwork? We install ductless mini-split heat pumps that provide cooling and supplemental heat without tearing into walls.

  • High-efficiency furnace replacements
  • Central A/C addition to existing ductwork
  • Ductless mini-split heat pump installation
  • Heating and cooling in one unit (mini-splits)
