Lafayette’s housing is genuinely split between two worlds. On one street you’ll find a 1960s ranch with undersized metal ducts and a furnace that hasn’t had the blower pulled in years. Two streets over, up near the hills, there’s a 2010s build with long flex runs snaking through unconditioned attic space. Both need HVAC Cleaning, but they need it done differently. Our crews work throughout Lafayette, from the flat lots near downtown to the hillside homes off Moraga Road and St. Marys Road. We know the terrain, we know the housing stock, and we quote per system, not per vent.

Omar Haddad leads our team, and every one of our technicians is background-checked, uniformed, and will tell you their name before they arrive. When you book, you’ll get The Relay Standard: a live trackable arrival window, before-and-after photos of your own ducts, and a digital invoice you can pay from your phone. That’s how we do every job in Lafayette.

Why Cardinal Air Duct Cleaning Is Lafayette’s Preferred HVAC Cleaning Company

Lafayette homeowners call us because we do one thing and we do it without the games. We’re part of the Relay Home Co. family, founded in 2005, and every job carries the 365-Day Done Right Promise: if the work isn’t right within a full year, we return and correct it at no charge. That’s the longest-standing satisfaction window in the trade, and it applies to every booking without exception. No fine print, no “select jobs only.”

Our technicians run professional-grade equipment: Rotobrush rotary brush systems to agitate debris loose, Nikro HEPA vacuums for negative-pressure extraction (that means loosened debris goes straight into the vacuum, not back into your living room), and Abatement Technologies containment units when a Lafayette hillside home has a crawlspace or attic that needs protecting. You’ll know which tools are coming, and you’ll know your tech’s name before they open the door.

We answer the phone. A live person picks up 24/7, because nobody in Lafayette should have to leave a voicemail and wait a day while their AC coil is caked and the upstairs bedroom stays eight degrees hotter than the living room. When you call (737) 727-2314, we pick up. We schedule. We show up.

AC Coil Cleaning in Lafayette

AC Coil Cleaning in Lafayette runs $180 – $320 as part of a full system cleaning, and it’s the single most common request we get during the June through October stretch when the valley heat pushes into the Lamorinda hills. The evaporator coil sits inside the air handler and pulls heat out of the air as it passes over. When that coil gets coated with dust, pollen, and the fine oak debris Lafayette’s hillside trees drop into intake vents, the whole system works harder to move the same air. Your energy bill climbs. The bedroom over the garage won’t cool. That’s the coil telling you it needs cleaning.

Evaporator Coil Cleaning

We pull the access panel, inspect the coil under light, then apply a foaming coil cleaner and rinse gently enough that the coil fins don’t bend. On Lafayette ranch homes from the 1960s and 70s, we often find the coil hasn’t been touched since the system was installed. That’s not a judgment, it’s just what happens. When we’re done, we photograph the coil for your record.

Blower Cleaning

The blower wheel is what pushes air through the ducts, and in Lafayette homes near the open space, it collects a fine grey paste of dust and pollen inside the fins. A dirty blower can cut airflow by 20 to 30 percent. We pull the blower assembly, clean each fin, and remount it. It’s routine on most of our Lafayette jobs.

AC Cleaning in Lafayette

AC Cleaning in Lafayette means treating the entire air path, not just the visible parts. A full system cleaning runs $350 – $650 for a typical Lafayette home, and that covers the return, the supply runs, the air handler, the coil, and the blower all in one visit. We’re not pricing per vent. We agree on one flat price for the system before we start, and that price does not change when the hillside flex run turns out to be longer than the register suggested.

Condenser Cleaning

The condenser is the outdoor unit, and in Lafayette it lives under oak trees more often than not. That means the coil fins outside collect leaf litter, dust, and pollen that block heat from leaving the refrigerant. We clear the debris, straighten fins, and rinse the coil so the system can actually shed heat on a 95-degree day.

Air Handler Cleaning

The air handler in Lafayette homes is often tucked in a garage corner or an attic kneewall, and it pulls in whatever’s floating nearest. We vacuum the interior, clean the drain pan, check the condensate line, and make sure the unit isn’t pulling air from an unconditioned space. A dirty air handler is one of the quietest efficiency leaks in a home.

Trusted Brands We Service in Lafayette

Most Lafayette homes have one of a handful of systems: Carrier, Trane, Lennox, Rheem, or Goodman, with a fair share of Mitsubishi and Daikin mini-splits showing up on the newer hillside builds and guest units. We service all of them. We stock common filters, contactors, and caps locally so we can handle routine items without a second trip, and when filtration comes up, we carry Honeywell and Aprilaire media cabinets for homeowners who want something better than a one-inch fiberglass filter. If your system is older or uncommon, that’s fine too. We see it all in Lafayette.

Common HVAC Cleaning Problems We See in Lafayette Homes

• Crushed flex duct runs in hillside homes. Long flex runs through unconditioned attic space get bent, pinched, or crushed behind joists. Airflow at the register reads fine, but the bedroom never cools. We find these during cleaning and correct them without adding a per-vent upcharge.
• Pollen and oak debris packing the return side. Lafayette sits in dense tree cover, and the return grilles in your hallway pull in pollen, leaf dust, and wildfire ash residue that behaves differently from ordinary household dust. It coats the blower and coil fast.
• Undersized original ductwork in mid-century ranches. Homes built in the 1950s and 60s in downtown Lafayette and Burton Valley often have duct runs sized for a different era. Cleaning helps, but the real fix is knowing the system’s limits. We’ll tell you honestly what cleaning will and won’t solve.
• Dirty coils from years of deferred maintenance. When the coil is caked, the AC runs longer, bills go up, and the system works its compressor to an early death. Coil cleaning is the highest-ROI hour we spend on most Lafayette systems.
