No heat is four different jobs depending on what you have.

OilNozzle, filter, strainer and electrodes; combustion tested with instruments; the flue and chimney base looked at. Running out of oil is not a fault but it does mean a restart and a bleed.
Gas or propaneBurners, heat exchanger, flue integrity, and the safeties tested rather than observed. A compromised heat exchanger means the appliance is shut off, not repaired.
Boiler, any fuelCirculators, zone valves and the expansion vessel — where most boiler faults actually live. A radiator cold at the top is usually air; cold throughout is usually a valve.
Heat pumpReversing valve in both modes, defrost watched through rather than assumed, back-up heat staging, and the thermostat configuration read against the equipment.

Before you call, two free checks are worth thirty seconds: whether the thermostat is actually calling for heat, and whether the emergency switch at the top of the basement stairs has been knocked off. Between them they account for a surprising share of winter call-outs.

After that, it is a genuine fault and worth a visit rather than more poking about.

No ductwork is a design question, not a dead end.

A great many houses here heat by boiler and baseboard, which means there is nothing to connect cooling to. That leaves three honest answers, and which suits you depends on the building rather than on what we stock.

Ductless headsA three-inch penetration per unit, room-by-room control, no duct losses. The indoor units are visible and some people mind that a great deal.
Small-duct high-velocityTwo-inch tubing through joist bays, small round outlets. Far less invasive than conventional ducting; fewer contractors work with it.
Conventional ducts, retrofittedPossible, and in a house like this it is mostly carpentry. The cost is in the building work, not the equipment.

A wall-mounted ductless indoor unit high on the wall of an older room, with the line set cover running neatly down to the floor.

Two rooms is often the right answer, not eight.

Where two rooms are genuinely uncomfortable and the rest of the house is fine, fitting a whole-house system to solve two rooms is an expensive way to be right. Two heads, sized for those two rooms, frequently is the answer.

It is a smaller job and it gets proposed less often for exactly that reason. We would rather quote it and be asked back than quote the large one and be compared.

Before any replacementA load calculation for the house, room by room, from the building rather than from the old badge.
Distribution assessedStatic pressure where there are ducts; the circuit and emitters where there is a boiler.
Electrical supply checkedParticularly where a heat pump is being considered. It is what turns a simple change into a larger job.
