Rooms far from the furnace stay cold
Long duct runs added during a conversion lose heat and pressure before they reach the back of the house. A technician can measure airflow at each register and seal or resize the worst runs.

Forced-air furnaces in converted bungalows and mid-century homes: no heat, short cycling, and furnaces that run but leave the far bedrooms cold.

Leaky return ducts pull in basement dust and unheated air. Sealing the returns often reduces dust, shortens run times and lowers the gas bill.
Some homes have a boiler for the original rooms and a furnace for an addition. Each needs its own service, and the controls should be checked so the two aren’t working against each other.
Ask for the ductwork to be checked during the estimate. If the ducts are undersized, a bigger furnace won’t fix the cold rooms, and the right answer may be duct changes or a two-stage furnace that runs longer at a lower output.
If the house still has an unlined masonry chimney, find out whether the water heater will be left venting alone in it after the furnace moves to side-wall venting. That decides whether a chimney liner belongs in the estimate.

If the boiler is working and you like radiator heat, keeping it is usually the cheaper path, and cooling can be added with mini splits or high-velocity AC. Converting to a furnace makes sense mainly when the home already has good ductwork.
Common causes are a clogged filter, leaky or undersized ducts, a failing blower or a furnace that is too small for the house. Measurements of temperature rise and airflow show which one it is.
