Wall furnaces, heaters, and the accessories that keep them running.
Williams has been manufacturing heating equipment in California for over a century. Buy the same units, replacement parts, and accessories straight from the factory, with technical support from the people who build them.
Wall furnaces put the heat where you need it, without a duct system to install or maintain.
Monterey
Williams wall furnaces heat a room or a whole home without ductwork. Choose a top vent model for a standard flue, a direct vent model that draws combustion air from outside through a sealed system, or a gravity unit that runs without electricity so the heat stays on when the power does not. Every unit ships from our California factory with the manuals, venting information, and support you need to install it correctly the first time.
The pieces that finish the job. Wall and floor registers, thermostats and wall controls, venting kits, blowers, mounting hardware, and trim built to fit Williams units exactly, because the same factory makes both. Ordering the accessory with the unit means one shipment, one set of part numbers that already match, and no standing at a counter guessing at fitment.
Overstock runs, discontinued finishes, and superseded models at a factory-direct discount. These are new Williams products from the same line as everything else we build, priced down because we need the floor space, not because anything is wrong with them. Quantities are limited and clearance stock is not restocked, so if the model you need is listed, take it.
The AH/AV-B air handler packs durable steel construction, smooth balanced airflow, and factory-mounted controls into a simple, single-point power design. Dual access doors and vibration isolators (sizes 008–040) make service easy and operation quiet.
