Remove Buildup and Stop Air from Escaping

Duct cleaning and sealing services available in El Cajon, California for homes dealing with dusty vents or uneven airflow.

When dust blows out of your vents every time the system starts, or certain rooms never reach the temperature you set on the thermostat, your ductwork may be clogged with debris or leaking conditioned air into unconditioned spaces. In El Cajon, older homes and systems that haven't been maintained often accumulate years of dust, pet hair, and other particles inside the ducts. Cano Air Conditioning & Heating Inc. cleans ductwork to remove buildup and seals leaks that waste energy and reduce comfort.

We use specialized equipment to dislodge debris from duct surfaces and extract it through a vacuum system connected to your main trunk line. After cleaning, we inspect joints, seams, and connections for gaps where air escapes, then apply mastic sealant or metal-backed tape to close those leaks. The result is improved airflow to every room and less strain on your heating and cooling equipment.

If your home in El Cajon has inconsistent temperatures or dusty air coming from the vents, reach out to schedule a duct inspection and discuss cleaning or sealing.

What we do inside your ductwork

We start by accessing your duct system through the main trunk line or individual registers, then use rotating brushes and compressed air to loosen dust and debris from the interior walls. A high-powered vacuum pulls the dislodged material out of the system and into a containment unit, preventing it from circulating back into your home. In El Cajon, we often find construction dust, insulation fragments, and years of accumulated particulates in ducts that haven't been cleaned since installation.

Once the ducts are clean, you'll notice air flowing more freely from each vent and less dust settling on furniture after the system runs. Rooms that used to feel stuffy or receive weak airflow will start to match the temperature you set on the thermostat.

After cleaning, we inspect for leaks at joints, connections, and seams, especially in attics or crawl spaces where ducts are exposed. Leaky ducts lose conditioned air before it reaches living spaces, forcing your system to run longer to maintain comfort. We seal gaps with mastic or foil tape rated for HVAC use, which restores proper airflow and reduces energy waste. This service doesn't address structural duct damage or disconnected sections, which require separate repair work.

Let's answer what you're probably wondering

Homeowners in El Cajon usually ask how often ducts need cleaning, whether sealing will make a noticeable difference, and how we access ductwork without damaging walls or ceilings.

How often should ductwork be cleaned?
Most homes benefit from duct cleaning every three to five years, depending on factors like pets, recent renovations, and how much dust accumulates in your home. If you've never had your ducts cleaned and notice dusty air from vents, it's likely overdue.
What happens if ducts are leaking air?
Leaky ducts allow heated or cooled air to escape into attics, crawl spaces, or wall cavities before reaching your rooms. You'll notice longer runtimes, higher energy bills, and inconsistent temperatures throughout your home.
How do you access the ductwork without tearing up walls?
We access ducts through existing registers, the air handler, or small openings in the trunk line that we seal after cleaning. In most El Cajon homes, we don't need to cut into walls or ceilings to complete the work.
Will I see lower energy bills after sealing?
Sealing leaks reduces the amount of conditioned air lost before it reaches your living spaces, which means your system runs less to maintain temperature. You'll typically notice a reduction in monthly energy costs, especially during peak heating and cooling months.
What if my ducts have mold or strong odors?
We inspect for visible mold and moisture sources during cleaning and recommend remediation if needed. Strong odors often come from accumulated debris, pet dander, or mildew, which cleaning typically resolves unless there's an underlying moisture issue.
