Furnace repair inRichmond

Richmond's heating equipment lives somewhere damp

Most Richmond homes have no basement. The furnace is in a crawlspace, a garage or a utility room — and in a city with this water table, that changes how equipment ages.

Crawlspace furnaces sit in an environment that's humid most of the year and occasionally has standing water. Over fifteen or twenty years that produces failures you see less often elsewhere:

External corrosion on the cabinet, the burner assembly and the flue connections.

Corroded electrical connections and control boards — humidity gets into things that were designed for a dry basement.

Rusted condensate traps and drains on high-efficiency units, which then block and trip the safety switch. This is a common Richmond call and it presents as a furnace that starts, runs briefly, and shuts down.

Ductwork corrosion and separation, particularly where ducts run through the crawlspace itself. A separated duct in a damp crawlspace is heating the crawlspace and pulling humid air into the house.

We check all of that, because on a Richmond furnace the fault is often environmental rather than mechanical — and fixing the component without addressing the environment means we'll be back.

What we look at while we're under there

Since a crawlspace furnace call puts us in the same place as everything else that goes wrong in a Richmond home, we check and report on three things at no charge:

Crawlspace moisture and whether the ground cover or vapour barrier is doing anything.

The sump pump, which in much of Richmond is the only thing keeping groundwater out.

Duct condition, since separated or corroded ducts in a damp crawlspace waste a substantial share of what you're paying to heat.

The rest of the usual

Blowing cold air — ignition or the flame sensor.

Not starting — thermostat, breaker, safety limit, control board.

Short-cycling — airflow, or in Richmond frequently a blocked condensate drain.

Noise — blower motor, or delayed ignition.

⚠️ Persistent burning or acrid smell: turn it off and call.

⚠️ CO alarm: leave the building, call 911 from outside, don't investigate.

Repair or replace

Richmond's housing skews to the late 1970s through the 1990s, which means many original furnaces have already been replaced once and the current unit is fifteen to twenty-five years old. Combined with the crawlspace environment, that's a shorter effective life than the same unit would have in a dry basement.

We'll tell you which side of the line you're on and give you both numbers. If replacement is the answer, it's also the moment to ask whether a heat pump or dual-fuel makes sense — you're spending ⁨$5,000–$9,000⁩ anyway, and the incremental cost is smaller than the headline figures suggest.
