Cleaning & Care
Air Duct Cleaning
Our negative-air machine seals onto the main trunk duct and puts the whole system under suction first. Then each run is scrubbed individually, so years of dust and debris travel one way only — out of the ducts and into the machine. In San Diego County, open-window months load systems steadily, and every run gets scrubbed along its full length. That is air duct cleaning in Coronado, CA, done the way it should be.

A duct system in Coronado may face wildfire smoke, valley heat, coastal moisture or all three across the year. This is what we actually find here, and what we check on every visit.
Smoke is the finest dust there is, and during fire season it penetrates homes across Coronado even with windows shut. The duct system collects it in the trunk and returns, and after the skies clear the house keeps recirculating that residue - and its smell - until the system is cleaned from the trunk out.
Inland Coronado summers push attics to extremes, and the ductwork living there ages fast - tape dries, flex jackets get brittle, joints separate. Cooled air leaks overhead while the system runs long afternoons, and sealing is usually where the fix starts.
Many Coronado neighborhoods carry duct systems installed decades ago - undersized returns, unsealed seams, runs that were never insulated. The equipment may have been replaced twice while the ducts stayed original, and the inspection shows what that means for airflow and dust.
With something blooming in California in almost every month, pollen is not a season here so much as a rotation - trees, grasses, weeds in turn. Return ducts collect each wave, and allergy households feel the stored load most when the house is sealed tight.

Every few years for most Coronado homes - sooner after a heavy smoke season, a remodel, or in allergy households. Coastal and inland systems age differently, so we camera-inspect free and show you your own trunk; the right interval comes from what is actually in there.
Our negative-air machine seals onto the main trunk duct and puts the whole system under suction first. Then each individual run is scrubbed on its own, so loosened dust and smoke residue travel toward the trunk and into the machine - never back into your rooms. We finish at the registers and show you the before-and-after on camera.
Usually the run serving it: a separated attic joint, a kinked flex run, or a conversion room tied into an undersized trunk. In Coronado we trace the run on the inspection camera, and repair, sealing or a properly sized new run fixes it at the cause.
Yes - original ductwork is the most common hidden cause of comfort and dust complaints in older Coronado homes. The camera shows buildup, leaks and undersized returns plainly, and you can decide what, if anything, is worth doing from evidence.
In inland Coronado homes with attic systems, leaks spill cooled air into a hot attic on every cycle, and sealing them means the equipment runs less to hold temperature. We leak-check on every inspection and tell you plainly which work would actually pay off.
No — and be wary of anyone who does. Every duct system is a different size and condition, so a phone price is a guess that changes at your door. Our inspections and estimates are free: a tech looks inside your actual ductwork first, then gives you one clear price before any work starts.
