What San Francisco Homeowners Say About Linden Air Duct San Francisco
Reviews matter because ductwork is invisible. You can’t see what we cleaned, so you need to hear it from someone who watched the whole job and checked the results afterward. That’s how we earn the things people say about us: the tech’s name and photo arrive before the visit, the price is in writing before any work starts, and every repair carries a written 365-day guarantee. No surprises, no vague invoices, no wondering whether the job was actually done. Just clean air and a paper trail to prove it.
Recent Reviews
Our 1920s Marina flat had ducts that hadn’t been opened in decades. The tech showed me the before-and-after photos of the return plenum and I honestly didn’t recognize it. He pointed out a disconnected branch in the crawl space that was pulling in cold fog-damp air, repaired it, and the musty smell was gone by that evening.

I called because the master bedroom always felt five degrees warmer than the rest of the house no matter what the thermostat said. Linden’s crew found the issue in the duct run under the hallway: a crushed section behind the lath and plaster. The written quote matched the final invoice to the dollar, and the photo badge at the door told me exactly who I was letting in.
David Y. – Glen Park, San Francisco
We’d had our ducts “cleaned” three years ago by one of those coupon outfits. The tech spent six hours with a Rotobrush negative-pressure setup and pulled out what looked like a small dog’s worth of Victoriana-era dust and construction debris. He showed me the collection canister before and after. That’s how you know the work actually happened.
Oscar R. – Noe Valley, San Francisco
The price was the first thing that felt different. I got a written number for the whole system before the guy unloaded a single tool. No per-vent upsell, no “Oh, this is worse than we thought” phone call. He finished in one visit, walked me through the photos on his tablet, and handed me the guarantee paperwork without me asking.

We live near the panhandle and the tree debris plus decades of dog hair had turned our returns into felt. The crew lead was the same person whose photo and name I’d received by text that morning. He did a negative-pressure extraction on every register, sealed a small leak in the trunk line, and the furnace has been noticeably quieter since.
Rosa G. – Haight-Ashbury, San Francisco
I manage a four-unit building in the Richmond and the tenants on the top floor kept complaining about dust on every surface. Linden cleaned the shared duct runs and found the real culprit: a disconnected dryer vent in the wall cavity that had been blowing lint into the chase for who knows how long. They repaired the run, cleaned the whole system, and sent one flat invoice.

Why Customers Trust Us
These reviews share a pattern. The tech’s name and photo arrive before the visit. A photo ID badge is shown at the door, every time. The price is put in writing before any work begins, so the number you agree to is the number you pay. And if the repair doesn’t hold, Linden comes back at no charge under the 365-day Done Right Promise. That’s the Threshold Standard, and it has been in place since 2004 under our ownership alongside the Threshold Group family. Every technician is background-checked, identity-verified, and trained on Rotobrush and Nikro equipment. We believe a good review isn’t just a compliment. It’s what happens when a company gives you the information you need before you ever make the call. And if you’d rather talk it through first, a live person answers at (951) 527-6259, any time of day.
