Your ductwork is the circulatory system of your home’s HVAC. When ducts are dirty, leaking, or damaged, your system works harder, your air quality suffers, and your energy bills climb. Circulating Air provides professional duct cleaning, sealing, and repair — done right by NATE-certified technicians who understand how ductwork affects everything else.

The Problem
When Your Ducts Are Working Against You
Leaky ducts can waste 20–30% of your conditioned air before it ever reaches your living spaces. That’s money pumped into your attic, crawlspace, or walls every time your system runs. Add years of accumulated dust, debris, and potential mold growth inside your ductwork, and you’re not just losing efficiency — you’re circulating contaminants through every room.
Common signs of duct problems include uneven temperatures between rooms, excessive dust on surfaces, musty odors when the system runs, and energy bills that keep climbing despite a functioning HVAC system. If any of that sounds familiar, the problem might not be your equipment — it might be your ducts.

What We Do
Comprehensive Duct Services
We handle the full spectrum of residential ductwork — from cleaning and sealing to repair and replacement. Every service starts with a visual inspection so we can tell you exactly what your ducts need, not guess.
Duct Cleaning
Professional source-removal cleaning using negative-pressure equipment and mechanical agitation. We clean the entire duct system — supply lines, return lines, registers, and the main trunk — not just the visible sections near vents.
Duct Sealing
We locate and seal leaks using mastic sealant and metal-backed tape at joints, connections, and penetrations. Proper sealing recovers lost conditioned air and can improve system efficiency by 15–20%.
Duct Repair
Crushed, disconnected, or deteriorated duct sections replaced with properly sized and insulated ductwork. We match materials and insulation values to your system requirements.
Replacement & Rerouting
For older homes with undersized, poorly designed, or failing duct systems, we design and install new ductwork that delivers balanced airflow to every room. New ductwork pairs well with a new AC system for maximum efficiency.
Insulation Upgrades
Duct insulation in attics and crawlspaces to reduce thermal loss. Especially important in LA, where attic temperatures can exceed 150°F in summer — uninsulated ducts in that environment waste significant energy.

3
Professional Service

Common Questions About Duct Services
The questions we hear most — answered before we’re on your roof.
How often should ducts be cleaned?
For most homes, every 5–7 years is sufficient. You may need cleaning sooner if you’ve completed a renovation (drywall dust is a major contaminant), have pets, or notice visible dust buildup at registers. We’ll inspect and give you an honest assessment — we won’t recommend cleaning you don’t need.
How do I know if my ducts are leaking?
Common signs include rooms that are consistently hotter or cooler than others, higher-than-expected energy bills, visible gaps at duct connections in attics or crawlspaces, and excessive dust. A professional inspection confirms the location and severity of leaks. If you’re noticing any of these, it’s worth having us take a look — there’s no cost for the initial assessment.
Is duct cleaning worth it, or is it a scam?
Legitimate duct cleaning — done with proper source-removal equipment by trained technicians — is a real service with real benefits. The scams come from companies offering suspiciously cheap prices and doing little more than running a brush through a few feet of duct. Our service covers the entire system, and we show you before-and-after results.
