Air Duct Cleaning in Sunnyvale, CA

Frequently Asked Questions

My house is an Eichler with ducts that were added later. Can you even clean those?

Usually yes, but it depends on where the ducts ended up. On Eichler-era flat-roof homes, retrofit ducting tends to run either through furred-down soffits inside the house or across the roof in insulated housings. Neither one gives us the open attic we'd get in a conventional home. We walk the system first and find the access points: supply registers, the return, and any panels a previous contractor left. If the runs are flex in a tight chase, we clean what we can reach safely and tell you straight which sections we can't get to, rather than claiming the whole system is done. Homes that went to mini-splits instead of ducting usually don't need duct cleaning at all, and we'll say so.

We just finished a remodel. Should we clean the ducts now or wait?

Wait until the dusty work is finished: demo, drywall, sanding, flooring. Sunnyvale has a lot of ongoing remodel activity, and drywall dust is the most common thing we pull out of systems here. It's fine enough to pass through a standard filter, and it coats the inside of sheet metal and settles into flex ridges. If the furnace ran at all during construction, that debris is already distributed through the whole system. Cleaning after the last trade leaves is the one that actually holds.

How fast can someone get out here?

Sunnyvale is in our regular service area, and most jobs get booked within a few days. Late spring through summer runs busier, since that's when people notice the cooling season dragging on and the pollen complaints start, so booking a week out is realistic then. If you call in the morning we can sometimes work you in the same day, though an Eichler with roof-mounted or soffit ducting usually isn't the one we squeeze in. Those take a proper look before we commit to a time.

What usually turns out to be wrong with ducts in older homes around here?

Kinked and crushed flex is the big one, especially where ducts were fitted into tight furred-down spaces that weren't designed for them. A sharp bend chokes airflow and collects debris at the pinch point. On the postwar ranch tracts with attic ductwork, we see disconnected or sagging flex runs, old sheet metal with loose joints, and attic insulation that's worked its way into the duct. Long cooling seasons mean the system runs a lot, so anything loose gets worse over time instead of sitting still.

What makes one Sunnyvale job cost more than another?

Access, mostly. A single-story ranch with a walkable attic and clean sheet metal is straightforward. An Eichler where the runs are in soffits or on the roof takes longer, needs more care, and sometimes requires creating access. That's where the number moves. The other factors are the number of supply registers, whether there's one system or two, and what's actually in there. Years of pollen from mature landscaping is routine. Construction dust from a remodel, or flex that's partly collapsed, means more time. We look at the system and tell you what we're dealing with before we start pulling anything apart.
