AfterHow Much Does Air Duct Cleaning Cost in Modesto?
Air duct cleaning in Modesto typically costs $350 to $700 for a standard single-story home with one HVAC system, and $600 to $1,200 for larger two-story houses or homes with multiple systems. Dryer vent cleaning runs $120 to $220 on its own, and air duct repair is quoted per job once we’ve seen the damage. The written estimate sets the final price, and we don’t charge for the estimate itself.
Modesto’s dry, hot summers and cool, mild winters mean the HVAC system runs hard for months, pulling dust, pollen, and Central Valley agricultural debris through the same ductwork year after year. That load is why duct cleaning here is less about cosmetics and more about how the system performs and what ends up in the air you breathe indoors. Our technicians have up to 13 years of experience, and we bring Rotobrush rotary brush systems and Nikro negative-air machines to every job – the same core equipment commercial contractors rely on.
Key takeaways:
- Typical full-home duct cleaning in Modesto: $350-$700 for one system, $600-$1,200 for two systems or larger homes.
- Dryer vent cleaning is a safety service, priced $120-$220 as a standalone job.
- Air duct repair is priced per job based on the damage, not a flat fee.
- Estimates are free. Call (866) 256-3971. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Air Duct Cleaning Cost Breakdown (2026)
Here’s how the numbers usually break down for Modesto homes. These are typical estimated ranges, not a quote – the written estimate you receive is what you pay.
| Line item | Typical estimated range |
|---|---|
| Full-home duct cleaning, one HVAC system (up to about 12 vents) | $350 – $700 |
| Full-home duct cleaning, two systems or a larger two-story home | $600 – $1,200 |
| Additional return duct or extra zone | $60 – $150 each |
| Dryer vent cleaning (standalone) | $120 – $220 |
| Air duct repair (sealing, reconnecting, patching) | Quoted per job after inspection |
| Sanitizing or deodorizing treatment | $80 – $200 |
| Containment setup with Abatement Technologies equipment (heavy contamination) | Included in the quoted job price |
What pushes the price up? More vents, more systems, and harder access. A single-story ranch home with a straight attic run and easy vent access sits at the low end. A two-story home with two systems, long runs, or ductwork boxed in behind drywall sits higher because the work takes longer and the containment setup is more involved. Heavy contamination – years of buildup, pest debris, or a system that’s been run with a failing filter – adds labor and often requires full negative-air containment with Abatement Technologies equipment. Homes where we find disconnected or crushed flex duct during the clean move into repair pricing, and that’s handled as a separate line on the estimate.

What Affects Air Duct Cleaning Pricing in Modesto
Modesto homes vary a lot – 1950s bungalows near downtown, newer builds out in the northeast neighborhoods, and everything in between. Here’s what actually moves the price on a Modesto job.
- Number of HVAC systems. One system is the baseline. Two systems roughly doubles the ductwork being cleaned, and the pricing reflects that.
- Home size and vent count. A 1,200-square-foot home with 10 vents is a shorter job than a 2,800-square-foot home with 24 vents across two systems. Vent count is the single biggest driver.
- Ductwork condition and access. Attic runs in Modesto’s older homes are often tight, with limited crawl space and flex duct that’s been baking under the summer heat for years. Hard-to-reach runs take more time. Crushed or disconnected ductwork moves the job into repair territory.
- Level of contamination. Central Valley dust, pollen, and agricultural particulate build up in ductwork over time. Light dust is a routine clean. Heavy accumulation, pest debris, or visible mold requires containment setup with Abatement Technologies negative-air equipment and more labor.
- Duct material. Sheet metal, flex duct, and ductboard each clean differently. Rotobrush rotary brush systems handle all three, but flex duct requires gentler brush heads and more care, which adds time.
- Add-ons. Filter upgrades, indoor air quality components like Aprilaire or Honeywell systems, and sanitizing treatments are quoted separately. If your home already has Aprilaire or Honeywell equipment, we can work with it rather than around it.
How to Save on Air Duct Cleaning
You don’t need a coupon to keep the price reasonable. A few practical moves help.
- Get the estimate in writing before work starts. Free estimates exist for a reason. Call (866) 256-3971 and get a number in writing – no surprise line items later.
- Bundle the dryer vent. Having the dryer vent cleaned on the same visit as the ducts cuts the labor time versus booking two separate appointments. It’s a fire-prevention service, and it’s worth doing.
- Fix leaks before they spread. If the inspection finds a small disconnected joint or a minor tear, repairing it now is cheaper than waiting until the whole run needs replacement.
- Keep filters changed. A clean filter slows the rate at which ductwork gets dirty again. It’s the cheapest maintenance you can do.
- Address the whole system once. Cleaning ducts but leaving a leaky return or a failing connection means you’ll be back in the same spot sooner. We work on the duct system, not just around it.
- Ask about the equipment. A shop vac and a marketing pitch won’t reach the full length of your ductwork. Rotobrush rotary brush systems and Nikro negative-air machines do. That’s what you’re paying for.
Does Modesto’s Climate Make Duct Cleaning More Important?
Yes, in a practical way. Modesto sits in the Central Valley, where summers are hot and dry and the air carries dust, pollen, and agricultural particulate through much of the year. Your HVAC system pulls that air in, filters some of it, and pushes the rest through the ductwork. Over several cooling seasons, that buildup is real. It shows up as dust settling on surfaces shortly after cleaning, higher energy use as the system works harder against restricted airflow, and in some homes, a musty smell when the system kicks on. Cleaning the ducts removes what’s accumulated and lets the system run the way it was designed to. If you suspect your ductwork is also damaged – sagging flex runs in a hot attic, disconnected joints, crushed sections – that’s when air duct repair comes in alongside the clean. Our technicians have up to 13 years of experience, and we carry the equipment to handle both in one visit.
Dryer Vent Cleaning: The Safety Line Item Worth Pricing In
Dryer vent cleaning isn’t an add-on afterthought. Lint accumulation inside a dryer vent is one of the leading causes of residential fires, and it builds up quietly behind the dryer where most homeowners never look. A standalone dryer vent cleaning in Modesto runs $120 to $220 depending on vent length and routing – a short straight run to an exterior wall is at the low end, a long run through a roof or a wall with multiple elbows is higher. We treat it as a dedicated safety service, not padding on the duct clean. If it’s been a few years since your dryer vent was cleaned, or you notice clothes taking longer to dry, that’s the signal to have it looked at. Call (866) 256-3971 for a free estimate.
What Should You Ask Before Hiring a Duct Cleaner in Modesto?
Ask what equipment they’ll bring and whether they use negative-air containment. Those two answers separate a real duct cleaning from a surface pass. Here’s what to cover:
- Equipment. Rotary brush systems and negative-air machines are the standard. Ask for brand names. Rotobrush and Nikro are the names you want to hear.
- Containment. A proper clean uses negative air pressure to keep debris from spreading into the living space. Abatement Technologies systems are what remediation-level work uses.
- Scope in writing. The estimate should list vents, returns, systems, and any add-ons. “It depends” without a number is not an estimate.
- Repair capability. If they find damaged ductwork, can they fix it? Cleaning around a problem doesn’t solve it.
- Dryer vent. Ask whether dryer vent cleaning is part of the service or whether you need a separate call. With us, it’s a dedicated service.
FAQs – Air Duct Cleaning Cost
How much does air duct cleaning cost in Modesto?
Air duct cleaning in Modesto typically costs $350 to $700 for a single-system home and $600 to $1,200 for two systems or a larger two-story house. The written estimate sets the final price, and estimates are free. Call (866) 256-3971 for an exact quote.
Is it cheaper to repair or replace damaged ductwork?
Repair is nearly always cheaper than replacement when the damage is localized – a disconnected joint, a crushed section, a torn flex run. Replacement only makes sense when a long run is failing throughout or the duct material has deteriorated past repair. An inspection tells you which situation you’re in before you commit to either. Call (866) 256-3971 for a free estimate.
How much does dryer vent cleaning cost in Modesto?
Dryer vent cleaning in Modesto typically costs $120 to $220 as a standalone service, depending on vent length and routing. It’s a fire-prevention service, not a cosmetic one. Call (866) 256-3971 for an exact quote.
Can you come today?
Same-day service is often possible depending on the schedule. We answer 24/7, and a call outside dispatch hours is booked into the next opening, Sunday through Friday, 7am to 7pm. Call (866) 256-3971 to check availability.
Do I need to be home during the duct cleaning?
It’s a good idea to be home for the walkthrough so we can show you what we find and confirm the scope. The job itself moves quickly once containment is set up – a single-system home is usually done within a few hours. Call (866) 256-3971 to get on the schedule.
