Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Carrier Air Duct Cleaning in San Diego, CA | Hollis Air Duct Cleaning
We clean Carrier air duct systems throughout our San Diego service area as an independent service provider, not a Carrier dealership or authorized shop. What sets our Carrier work apart here is that we account for the marine layer and salt air that punish ductwork in beach neighborhoods like Ocean Beach and Mission Beach. Most Carrier owners don’t realize their rusted register boots and musty coil odor are local problems, not equipment failures. Call (361) 326-5060 for a free estimate on Carrier duct cleaning anywhere in San Diego.
Why San Diego Residents Choose Us for Carrier Service
We’re independent our Carrier services specialists. That wording matters because we don’t answer to a corporate parts matrix or a manufacturer’s upsell playbook. Roy Castellanos, our owner, spent years in the mechanical trades before founding Hollis Air Duct Cleaning, and he holds our crews to a simple standard on every Carrier system we touch: find the real problem, write the price down, and leave the ducts cleaner than we found them.
Our technicians have worked on Carrier equipment from 1980s WeatherMaker furnaces in coastal bungalows to modern Infinity variable-speed air handlers in Carmel Valley and newer inland tract homes. That range means we recognize the failure pattern before we open the cabinet. We also carry OEM-compatible filters, collars, and duct sealing mastic on the truck, so a San Diego appointment doesn’t stall waiting on a parts house. Every job gets a written price before work starts and a 365-Day Done Right Promise in writing. Clean ducts, straight answers – that’s the whole job.
Common Carrier Air Duct Cleaning Problems We Solve in San Diego
- Rusted-through evaporator coil cabinets and drain pans near the coast. In Ocean Beach, Pacific Beach, and La Jolla, salt-laden marine air corrodes the metal pan on Carrier Performance and Infinity coils. The pan leaks, water soaks the flex duct insulation below, and suddenly a simple cleaning becomes a mold and rust repair. We see this weekly along the San Diego shoreline.
- Sagging and torn Carrier flex duct runs at the plenum collar in inland tract homes. Builder-grade flexible duct separates from the metal collar after 15 to 20 years in Carmel Valley, Mira Mesa, and Otay Ranch homes. The tear pulls attic dust and fiberglass directly into the supply stream, and the sagging run chokes airflow to one side of the house. We repair the collar, reroute the sag, and seal it with mastic.
- Mold and biofilm growth on Carrier evaporator coils from the marine layer. San Diego’s May Gray and June Gloom keep relative humidity high while mild temperatures mean the AC barely runs. That’s the perfect recipe for microbial growth on coil fins and cabinet walls. Carrier Comfort and Infinity systems near the coast often smell musty even when the thermostat hasn’t called for cooling in days.
- Flaking internal insulation in 1980s WeatherMaker furnace cabinets. Original Carrier WeatherMaker units in North Park, Hillcrest, and South Park still have fiberglass insulation lining the blower compartment. After 30-plus years, it degrades and flakes into the blower wheel and supply ducts. Cleaning the ducts alone won’t fix it; the cabinet has to be addressed too.
- Patchwork duct runs after decades of San Diego remodels. The region loves add-ons and ADUs. We routinely find a 1950s galvanized supply line spliced into a 1990s flex run into a 2010s Carrier air handler. Each transition is a leak point and a dust collector. Video inspection shows exactly where the system fails before we clean it.
Carrier Service in San Diego: What Local Conditions Mean for Your Equipment
In beach-adjacent neighborhoods like Ocean Beach and Mission Beach, Carrier duct boots and registers routinely rust from salt-laden ocean air, a problem you won’t find in inland San Diego or most other California markets. The boots are the metal fittings where the duct meets the floor or wall register, and once they corrode, they crumble at the edges and leak conditioned air into the crawlspace or wall cavity. That means residential duct cleaning here often includes replacing corroded boots before sealing, not just vacuuming. A standard duct cleaning in, say, Temecula or Rancho Bernardo might take three hours. A thorough Carrier duct service in a 1940s Ocean Beach bungalow can take six because the boots need replacement, the register faces are rusted, and the whole run needs mastic sealing after the debris is extracted. We price that work upfront, in writing, and we don’t discover it on your dime.
Carrier Models & Products We Service in San Diego
We clean the full Carrier lineup you’re likely to find in San Diego homes. That includes the variable-speed Infinity series, the Performance line with matching evaporator coils, the builder-grade Comfort Series common in 1990s and 2000s tract homes, and the legacy WeatherMaker furnaces still running in coastal cottages. For repairs we use OEM Carrier coils, blower motors, and control boards when available, and solid aftermarket equivalents for standard wear items like filter racks and flex duct connectors. On systems older than 15 years with coil or heat exchanger corrosion, we give an honest repair-vs-replace assessment. Sometimes the duct cleaning and sealing cost is better spent toward a new system if the Carrier cabinet is rusted beyond safe cleaning. We’ll tell you straight, which is more than some shops will do.
Carrier Service Pricing in San Diego
Air Duct Cleaning - San Diego on a Carrier system typically runs $450 to $900 for a whole-home cleaning, depending on the number of systems and the condition of the ductwork. A single system in a condo or smaller bungalow usually lands at the lower end. Older coastal homes with rusted boots, moldy coils, or asbestos-wrapped original ducts (common in North Park and Hillcrest) run higher because the work includes boot replacement, coil cleaning, and safe material handling. A free estimate includes a video inspection of the key sections and a written price before any work starts. Call (361) 326-5060 for a precise number on your Carrier system in San Diego.

FAQs – Carrier Air Duct Cleaning in San Diego
The smell comes from mold and biofilm growing on the evaporator coil and interior cabinet walls, fed by San Diego’s year-round marine-layer humidity. Because our mild temperatures mean the system runs less, moisture sits on the coil and never gets baked off. The fix is coil cleaning, cabinet treatment, and often duct sealing to stop humid air from entering the return side. Call (361) 326-5060 and we’ll video-inspect the coil to confirm before quoting.
In most North Park homes, original galvanized ducts can be cleaned and sealed as long as the metal hasn’t rusted through. The caveat is that older furnace ducts in this area are sometimes wrapped in asbestos-containing insulation. If that’s present, it requires special handling before any cleaning can begin, and we’ll walk you through what that means and what it costs before you commit to anything.
Fifteen years is right on schedule for flex duct problems in newer inland San Diego tract homes. The flexible core separates from the plenum collar, the runs sag, and attic dust gets pulled into the supply stream. Builders also leave construction debris in the ducts. A 2010 system in Carmel Valley often has torn collars and sagging runs by now, and a cleaning plus collar repair restores airflow that’s quietly been getting worse. Call (361) 326-5060 for a video inspection and written price.
We replace them. Rusted boots in Mission Beach are a structural problem from salt air, not a cleaning issue. Vacuuming a corroded boot only moves the rust around. We remove the old boot, install a new one, and seal it with mastic so the connection is airtight. This is standard practice for coastal Carrier systems in San Diego, and our Dryer Vent Cleaning in San Diego is similarly priced in writing before we start.
In San Diego, every 4 to 6 years is reasonable for most Carrier systems, but coastal homes in Ocean Beach, Pacific Beach, and La Jolla often need attention every 3 to 4 years because salt air and marine humidity accelerate corrosion and microbial growth. Inland San Diego homes can stretch to 6 years. A video inspection tells you where your system falls. For an exact schedule and a written price, call (361) 326-5060.
