Installation planning · Air Zone Systems
A furnace heats air and distributes it through ducts. A boiler heats water or produces steam for a piped heating system. Start with how heat reaches your rooms today.

Air registers and ductwork point toward a forced-air system. Radiators, hot-water baseboards, or radiant floor piping point toward a water or steam system. Older radiators alone do not tell you whether the boiler makes steam or hot water. Share the equipment model and photographs if you are unsure.
Replacing a boiler and changing to a furnace are different projects. Ask a replacement quote to state which existing pipes, radiators, or ducts can remain after assessment. Ask a conversion quote to show new distribution work, routes through the house, and any openings or finishing work. Keeping an existing system type does not automatically mean every connected part can be reused.
A boiler does not provide air conditioning. If you also want cooling, discuss a separate cooling system. A furnace’s ducts may be usable with central cooling after assessment. Ductless heat pumps are another option for homes without ducts; equipment selection and room coverage need their own plan.

For either system, identify the fuel, equipment model, controls, venting, electrical work, removal, and any required permits. For a boiler, ask about connected pumps, valves, and piping. For a furnace, ask about duct connections and airflow. Do not assume that the cheaper equipment price represents the cheaper completed project.
Include the current fuel, approximate equipment age if known, the rooms served, and whether domestic hot water is connected to the boiler. Describe access to the equipment and any planned renovations. Air Zone can use those details to discuss the project scope and what Air Zone can provide.
General planning information. Equipment selection, price, scheduling, and project scope need to be confirmed for your property.
