Photo Gallery of Heating and Cooling Work

Photos of furnaces, air conditioners and ductless systems, grouped by the kind of work they show.

Heating and cooling equipment spends its life out of sight, in closets, basements and side yards, so photos are often the easiest way to see what a job looks like before anyone opens a panel. The photos run from a furnace taken apart for a repair to outdoor condensers and the indoor units of ductless systems.

Furnace Work

A furnace opened up for a repair, with the cooling coil above it and the burner compartment below.

Central Air Conditioners

Outdoor condensers on their pads: one with its coil cleaned, an older unit set in gravel, and a coil packed with seed fluff before cleaning.

Ductless Mini-Splits

Wall-mounted and floor-mounted indoor units, and an outdoor unit on a deck with its lines in a cover.

What the Photos Show About the Work

A furnace with its panels off shows how much sits inside a small cabinet: the burners and igniter at the bottom, the blower below them, and the cooling coil above in the same cabinet where central air shares the furnace’s ductwork. That shared space is why heating and cooling problems are often found together.

The outdoor condensers show how much the coil depends on air moving freely through it. Seed fluff in early summer, grass clippings and leaves can mat over the fins and make the system work harder. Keeping the coil clear is part of a spring tune-up.

Ductless units suit rooms and houses where adding ductwork would be difficult, a common situation in older homes. An outdoor unit connects to one or more indoor heads, mounted high on a wall or low on the floor as a console. A floor console makes sense where the wall space up high is taken by windows or a sloped ceiling, and it moves warm air along the floor, where it is felt first.

Photos of a repair in progress, like the opened furnace, also show why a repair is checked afterwards rather than judged by eye. Once the panels go back on, a furnace is usually run through a full heating cycle to confirm that it lights, heats, and shuts off as it should, and an air conditioner is run long enough to cool the coil and drain its condensate.
