Air Duct Cleaning in Belmont - One Flat Price, Before-and-After Photos

Fast, Reliable Air Duct Cleaning Across Belmont

Air duct cleaning in Belmont costs $450 – $850 for a typical single-family home, and the job takes about four to six hours from setup to final walkthrough. We’re not the cheapest option in town, and that’s deliberate: we run negative-pressure extraction with HEPA filtration on every job, which means the debris we loosen goes straight into the vacuum, not back into your living room. If you’re on Ralston Avenue, in the Carlmont hills, or down near Twin Pines Park, call (737) 727-2314 and we’ll give you a written price before any work starts.

Why Cardinal Air Duct Cleaning Is Belmont’s Preferred Air Duct Cleaning Company

Belmont homeowners call us because we explain exactly what we’ll do and what it costs before we touch a single register. Omar Haddad and our crew work the whole Peninsula, and we know what Belmont’s mid-century housing stock throws at an air duct system. The older the ducts, the more important the process matters, and we bring the right equipment for old galvanized runs: Rotobrush rotary brush systems for agitation, Nikro HEPA vacuums for extraction, and Abatement Technologies containment units so no dust escapes into the house. We hand every client a written price before work begins, and that price does not change at the door.

Every tech who walks into your Belmont home is background-checked and uniformed. You’ll know their name before they arrive. And when you book, you get The Relay Standard: a live arrival window you can track on your phone, before-and-after photos of your own ducts, and a digital invoice you pay from a link. Part of the Relay Home Co. family since 2005, we’re independently owned and operated, held to one standard and one standard only: total visibility from booking to invoice.

Residential Air Duct Cleaning in Belmont

Residential Air Duct Cleaning in Belmont is the service we run most often, and in this city it looks a little different than in the flatlands. Belmont sits in a pocket of the Peninsula where summer fog and winter damp push homeowners to run their heating far longer than the calendar suggests, which loads the air handler with fine dust before a single register is touched. Because so many Belmont homes were built mid-century with original galvanized supply and return ducts, “we clean every vent” is not the same as “we clean the system” – source removal in the duct runs matters more than the visible registers. A standard whole-system residential cleaning in Belmont runs $450 – $850, depending on home size and number of returns.

Supply and Return Duct Cleaning

The supply side pushes conditioned air out; the return side pulls room air back toward the blower. In Belmont’s older homes, the return trunk is where the real debris sits, because it’s been drawing unfiltered air through the same galvanized runs for forty or fifty years. We clean both sides, every time, and we don’t quote per-vent pricing. One flat price per system, agreed before we start.

Video Inspection and Air Handler Cleaning

Before we start, we run a camera through the main runs so you can see what’s actually in there. After we finish, we run it again. The blower motor and housing get cleaned by hand, not just wiped down, and we photograph the results. If you can’t see it, it didn’t happen; that’s why every job includes before-and-after photos of your own ducts.

Commercial Air Duct Cleaning in Belmont

Commercial Air Duct Cleaning in Belmont covers offices, medical suites, daycare centers, and small retail along El Camino Real and the industrial pockets near Harbor Boulevard. Commercial jobs run $0.25 – $0.45 per square foot for a standard system, with a minimum job size of about 2,500 square feet. We schedule work before or after business hours to avoid disrupting your people, and we provide the same written price guarantee we give homeowners. No surprise line items when the van shows up.

Full System Cleaning

We map the full duct network, identify every supply and return run, and clean each one with negative-pressure extraction. If your building has a roof-mounted unit serving the top floor, we clean that too. Commercial jobs often involve multiple air handlers, and we’ll give you a single written price for the entire system before any work starts.

Containment and Documentation

We set up Abatement Technologies containment barriers where needed so dust from the ductwork doesn’t end up on desks, equipment, or inventory. After the job, you’ll get a walkthrough with photos and a digital invoice you can pay from the link we send to your phone. Building managers in Belmont appreciate the paper trail – it’s how you prove the work was actually done.

Trusted Brands We Service in Belmont

We service and clean duct systems connected to Honeywell filtration media, Aprilaire whole-home purifiers, and Guardsman UV systems, among others. Belmont’s older homes often pair original ducts with newer filtration units, and that mismatch is common: a high-efficiency Aprilaire filter upstream of a dirty return trunk just pushes air through old debris. We also stock common filter sizes and can advise on whether your existing setup is working. You’ll get honest answers, not an upsell.

Common Air Duct Cleaning Problems We See in Belmont Homes

• Gray film on return grilles. We saw this on a 1958 ranch on a Belmont hillside street: the homeowner kept finding a fine gray film on the return grille within a month of changing the filter. A camera inspection showed the return trunk packed with construction dust left from a remodel and a partially blocked lint pathway near the air handler. We set up negative pressure with HEPA filtration, ran agitation tools through the supply and return ducts, and cleaned the blower motor and housing by hand. Before-and-after photographs of their own ducts were shown before we packed up, and the film stopped returning.
• Remodel dust in the ductwork. Belmont has a lot of homes that were renovated at some point, and drywall dust from a remodel will sit in horizontal returns for years. It doesn’t go anywhere on its own; it just recirculates every time the blower kicks on.
• Blocked return trunk from pet hair and lint. Older homes with a single large return on the main floor pull hair, lint, and whatever else toward the blower. By the time you notice weaker airflow, the trunk may be half blocked.
• Per-vent quotes that miss the real problem. A quote of “$39 a vent” on a Belmont rancher sounds cheap, but it only cleans the registers, not the trunk. You end up paying for a partial clean and still have to call someone else later. We quote one flat price per system, and that system includes the trunk, the runs, and the air handler.
