Air Duct Cleaning in Mission Viejo, CA

Probably not on its own, and we'd rather tell you that up front. In Mission Viejo's two-story tracts from the late 60s through the mid-80s, the air handler sits in the attic and the upstairs bedrooms are usually at the end of the longest flex runs. If that flex is the original R-4 or R-6, it's now past 40 years old, and we routinely find inner liners torn loose or collapsed where the duct sags over a truss. Cleaning a collapsed run doesn't restore the airflow. What we can do is open it up, show you what the camera sees, and tell you honestly whether the branch needs cleaning, repair, or replacement. Sometimes the answer is that one or two runs are the problem and the rest of the system is fine.

That's the most common call we get in this city, and duct cleaning usually isn't the culprit. In these homes it's almost always bypass at the filter grille or a leaking return plenum in the attic. If the filter grille doesn't seal tight to the ceiling or wall, the blower pulls unfiltered attic air straight past the filter, and attic air here is loaded with fine debris from the eucalyptus, pine, and sycamore canopy plus whatever blew in during the last Santa Ana. Same with an open return plenum seam. We check the grille seal and the return side before we quote a cleaning, because cleaning ducts that are being re-fed dirty air is money you won't be happy about.

Mission Viejo is central to the south county area we cover, so scheduling is usually within a few days, often sooner. Attic work is the variable. We try to put Mission Viejo attic jobs early in the morning from July through September, because the inland bowl keeps the marine layer out and attic temperatures climb fast once the sun is up. If you call mid-afternoon in late summer asking for someone that day, we'll likely offer you the next morning instead. That's for the quality of the work as much as anything.

Mostly the condition of what's up there and how many runs there are. A single-story tract home where the flex has been replaced at some point is a straightforward job. A two-story with original ductwork, long runs to the far bedrooms, and deteriorated inner liner is a different scope, because fragile 40-year-old flex has to be handled carefully or it comes apart. Number of supply registers matters too. Access plays in as well: some of these attics are tight above the second floor. We'll walk the attic and look at the registers before giving you a number, so what you hear reflects your house rather than an average.
