Air Duct Cleaning Company in Fontana - One Price Per System, Agreed Before We Start

Air Duct Cleaning Company in Fontana, CA

Lionheart Air Duct Cleaning has served Fontana since 2013, and the work here is not like the work in neighboring cities. We’re the duct company that repairs what we find, not just cleans around it. Fontana homes, especially the older south-side tracts and the newer north-side foothill subdivisions, have distinctly different duct problems, and both are made worse by the Cajon Pass wind corridor that pours abrasive silt into return-air grilles year-round. If your system is leaking, kinked, or clogged with desert dust, call (855) 356-4382 and we’ll tell you straight what’s actually going on.

Why Fontana Homes Are Different

Fontana sits in the path of two forces that wreck ductwork. First, the Cajon Pass wind corridor and Santa Ana events funnel fine desert dust and grit off the Lytle Creek and San Gabriel foothills directly into residential neighborhoods. Return-air grilles load up with a fine, abrasive silt that grinds through filters and coats the inside of duct trunks. Homes in 92335 and 92337, the postwar and 1950s-70s tracts south of the 10, have short, often rigid sheet-metal duct runs and original registers. Those systems were never designed for the dust load they carry now, and we routinely find leaky metal trunks and undersized returns that pull attic dust and rodent debris into the living space.

The northern foothill ZIP 92336 is a different story. Those 1990s-2000s builder subdivisions use flexible insulated duct in hot attics. Summer highs routinely exceed 100°F, and that heat cycling bakes the flex duct’s outer jacket until it cracks. Kinks, collapsed runs, and rodent intrusion are common. We find chewed flex duct and nests in attics that back onto the open wash and hillside, because the same Santa Ana winds that push dust onto the south side drive vermin up the slopes into those attics. Fontana is not a one-size-fits-all duct market, and a crew that treats it like one is going to miss the actual problem.

Our Main Fontana Services

Two services account for most of the calls we take from Fontana homeowners: full-system air duct cleaning and dryer vent cleaning. Both are driven by the same local conditions, and both are handled with the same professional-grade equipment we run on every job.

Air Duct Cleaning in Fontana

Fontana’s wind-driven dust means most homes need heavy dust-load cleaning, not the light routine maintenance that might pass in Rancho Cucamonga or Ontario. We run Rotobrush and Nikro systems, the same equipment professional HVAC and restoration contractors use, and we pair them with Abatement Technologies negative-air capability to contain the dust we dislodge. That containment matters in Fontana, where the dust load is heavy enough to spread through the house if it’s not controlled. See the full scope on our dedicated page for Air Duct Cleaning in Fontana.

Dryer Vent Cleaning in Fontana

Lint buildup is a leading cause of residential dryer fires, and Fontana’s dry, dusty air makes lint accumulate faster than homeowners expect. This is a safety service, not an upsell, and we treat it that way. The older south-side tracts often have long, awkward dryer vent runs through crawl spaces or exterior walls, and those collect lint quickly. The foothill homes have their own issues with vents that exit under eaves or through roof caps where birds nest. Get the details on our Dryer Vent Cleaning in Fontana page.

Air Duct Repair in Fontana

Air duct repair in Fontana is what separates a real duct specialist from a company that just runs a brush through the system. The south-side postwar homes in 92335 and 92337 have original sheet-metal ductwork that’s been leaking conditioned air into attics and wall cavities for fifty or sixty years, pulling dust, insulation, and rodent debris into the air you breathe. The north-side 1990s-2000s homes in 92336 have insulated flex duct in hot attics that kinks, tears, and gets chewed by rodents driven up from the wash by wind events. We diagnose the failure, replace or reseal what’s broken, and leave you with a system that actually moves air. That’s what Air Duct Repair means at Lionheart, and it’s a capability most standalone duct-cleaning companies don’t have.

Ductwork Repair

Signs you need it

Rooms that never reach the thermostat setting, whistling or rattling from wall registers, visible dust blowing out of supply vents, or utility bills that keep climbing even though the HVAC is serviced, all point to leaking or damaged ductwork rather than a furnace problem.

What it costs in Fontana

Ductwork repair in Fontana typically runs $350 to $850 per section depending on access, with attic and crawl space work at the higher end and exposed basement or garage runs at the lower end.

How we do it

We locate the leak or break with a pressure and visual inspection, seal accessible joints and seams with mastic and metal-backed tape, replace crushed or torn sections with properly sized material, and retest the run to confirm the repair actually stopped the loss.

Air Duct Replacement

Signs you need it

Ductwork that’s collapsed, torn beyond patching, contaminated with mold or rodent waste, or so undersized for your HVAC that no amount of sealing will balance the system, needs replacement rather than repair.

What it costs in Fontana

Air duct replacement in Fontana runs $1,950 to $3,800 for a typical single-system home, with older south-side homes on the lower end due to shorter metal runs and north-side flex duct homes on the higher end when attic access is tight and insulation must be moved.

How we do it

We remove the failed runs, size the replacement properly for your HVAC’s airflow requirements, install new rigid metal or insulated flex as the system calls for, seal every connection, and verify airflow at each register before we leave.

What Air Duct Repair Costs in Fontana

How do I know if my Fontana home needs duct repair or just cleaning?

If dust returns within weeks of a cleaning, rooms stay unevenly heated or cooled, or your energy bills rise without explanation, you have a structural duct problem, not a cleanliness problem. Cleaning a leaking system is a waste of money. Call (855) 356-4382 for an inspection first.

Does homeowners insurance cover air duct repair in Fontana?

Some policies cover duct replacement after a covered peril, like fire, water damage, or a roof collapse, but normal wear, rodent damage, and age-related failure typically are not covered. We can document what we find so you can file a claim if it qualifies.

Brands We Service in Fontana

We work across Honeywell and Aprilaire HVAC and indoor-air-quality configurations, and our cleaning and repair process integrates with Guardsman and Rotobrush systems. That brand range matters in Fontana, where south-side homes often run older builder-grade equipment and north-side homes carry newer, more complex systems. We keep common parts and fittings on the truck for most Fontana callouts. See our brands for the full technical range.
