Series 64 Pricing — 2026 D's Air & Heating
Larger boilers = lower cost per BTU. Although larger boilers have higher total project costs, the installed cost per BTU decreases as size increases because labor, controls, permitting, startup, engineering, commissioning, and project management costs are spread across more heating capacity.

Chicago's 6-flat and 12-flat apartment buildings built between 1900 and 1960 were almost universally heated with steam. When the original boiler fails, the Series 64 is the most common replacement choice — it's sized correctly for these buildings, it's compatible with existing steam piping and radiators, and it's built to last 40+ years with proper maintenance.
D's Air & Heating, Inc. handles every aspect of Series 64 commercial boiler replacement in Chicago. We pull all required permits, handle the gas piping and electrical connections, modify the flue piping, and commission the system before we leave. Our complete installed packages mean no surprises — the price you see is the price you pay.
