A new heating system should keep your building comfortable for decades. Commercial Tech, Inc. designs and installs commercial heating systems for offices, schools, churches, warehouses, retail, and multi-family buildings in Northern Virginia, Maryland, and Washington, D.C.

Heating Systems We Install

  • Commercial boilers, including high-efficiency condensing boilers
  • Hydronic piping, pumps, and heating loops
  • Gas-fired furnaces and rooftop units with gas heat
  • Heat pumps and VRF systems
  • Unit heaters and infrared heaters for warehouses and garages
  • Make-up air units for kitchens and industrial spaces

We install equipment from Carrier, Trane, Daikin, York, and other leading manufacturers.

How We Approach a Heating Installation

  • Survey the building, existing equipment, flue and venting, gas or electrical service, and controls.
  • Calculate the heating load so the new system is sized correctly.
  • Present equipment options with efficiency, cost, and expected life.
  • Coordinate removal of old equipment, rigging, piping, venting, and electrical work.
  • Start up, test, and commission the system, then walk your staff through operation.

Upgrading an Older Boiler or Furnace

Older boilers often run at efficiencies far below today’s condensing equipment. Replacing an aging boiler can reduce fuel costs and improve comfort. We also replace pumps, valves, and controls so the full system operates as one. Where it fits your building, we can recommend heat pump or hybrid options.

Planning Ahead

The best time to replace heating equipment is before it fails in January. If your system is nearing the end of its life, we can plan the installation during the off-season to avoid downtime.

Frequently Asked Questions

How long does a boiler replacement take?

Many single-boiler replacements are completed in a few days. Larger plants are phased so the building keeps heat during the project.

What size heating system does my building need?

It depends on square footage, insulation, ventilation, and occupancy. We perform a load calculation instead of simply matching the old unit’s size.

Should I replace a boiler with a heat pump?

Sometimes. Heat pumps and hybrid systems can lower operating costs in the right building, while hydronic buildings often benefit most from a high-efficiency condensing boiler. We compare both options for your building.
