AfterHow Much Does HVAC Cleaning Cost in Sunnyvale?
HVAC cleaning in Sunnyvale typically runs $350 to $700 for a standard single-family home, with most jobs landing around $475. That range covers a full air duct cleaning with professional-grade extraction equipment. Homes with heavy buildup, multiple zones, or damaged ductwork that needs repair can push toward $900 or more. If you’re only after dryer vent cleaning, that’s a separate service and usually runs $125 to $225.
The wide spread comes down to square footage, how many vents you have, and the condition of the system. A 1,400-square-foot ranch near downtown Sunnyvale prices very differently from a two-story in Ponderosa Park with a finished basement and 24 supply registers.
Key Takeaways
- Standard HVAC duct cleaning in Sunnyvale: $350 – $700, averaging about $475.
- Dryer vent cleaning on its own: $125 – $225.

- Systems with two HVAC units or heavy contamination cost more. Most single-system homes don’t.
- You get an exact price after an on-site assessment, and estimates are free.
HVAC Cleaning Cost Breakdown (2026)
Here’s how the line items break down for a typical Sunnyvale home. Ranges reflect what we and other professional duct cleaning companies in the area charge. Consumer-grade crews using a shop vac will quote lower – and they’re cleaning about as deep as a shop vac can reach, which isn’t far.
| Service | Typical Sunnyvale Price Range | What It Covers |
|---|---|---|
| Full air duct cleaning (single HVAC system) | $350 – $550 | All supply and return vents, registers, trunk lines, and main plenum |
| Air duct cleaning (two systems or per additional zone) | $175 – $275 per system | Each additional HVAC unit or zone cleaned with the same method |
| Dryer vent cleaning | $125 – $225 | Full vent run from dryer to exterior termination, lint removal, airflow check |
| Air duct repair (patch, reseal, reconnect) | $200 – $600 | Fixing disconnected joints, crushed flex duct, torn insulation, or leaking seams |
| Contaminated or remediation-level duct cleaning | $650 – $1,200 | Mold, pest debris, or construction dust requiring deeper HEPA extraction |
| Coil and component cleaning add-on | $150 – $300 | Evaporator coil, drain pan, and blower cabinet wiped and cleaned |
What pushes a job toward the top of the range? A second HVAC unit, heavy debris from a recent remodel, or a 1960s rancher with decades of dust in the trunks. What pulls it down? A single system, easy access to every register, and a home that’s been cleaned at least once in the past five years. If the crew has to move furniture, detach baffles, or reach a rooftop unit, that’s labor and it shows up in the quote.
We clean it. If we find damaged ductwork along the way, we repair it – Rotobrush rotary brush extraction and Nikro HEPA vacuum units are the standard equipment, but knowing how to seal a failing joint is the part that keeps your system running efficiently after we leave. You’ll want a duct company that handles both, so you’re not calling a second contractor after the cleaning reveals a problem.
What Affects HVAC Cleaning Pricing in Sunnyvale
- Square footage and vent count. Sunnyvale homes range from 900-square-foot condos near Murphy Avenue to 3,500-square-foot houses in the cherry orchard neighborhoods. Vent count is the real driver, not just square footage. A 20-register home takes roughly twice as long as a 10-register one.
- Number of HVAC systems. Many Sunnyvale homes have a single central system, but larger two-story homes and some of the newer developments along the Lawrence Expressway corridor have two. Each system is priced as its own job.
- Duct condition and accessibility. Older Sunnyvale homes – especially those built in the 1950s and 1960s – often have ductwork that’s been added to, patched, and routed through tight attic spaces. Crushed or disconnected sections add repair time. Reachable attic ductwork is faster to work on than ductwork buried under cabinets or through walls.
- Level of contamination. If you’ve had a remodel, a pest issue, or water intrusion, the cleanup goes deeper. Silicon Valley’s older homes with original duct lining hold more debris than you’d expect once the system is taken apart.
- Whether you combine services. Booking duct cleaning and dryer vent cleaning on the same visit usually costs less than booking them a month apart, because the technician is already on site with the truck and setup done.
- Timing and season. Spring and early summer are the heaviest months for duct cleaning in Sunnyvale, since homeowners are preparing for AC season. Booking off-season often means more scheduling flexibility and occasionally a better rate.
How to Save on HVAC Cleaning
There’s no reason to overpay, and there’s no reason to chase the cheapest coupon either. Here’s how we see homeowners get the most for their money.
- Book duct and dryer vent together. One trip, one setup, one visit. Combining the two services is usually cheaper than scheduling them separately, and your dryer vent is a fire risk without regular cleaning – treating it like a checkbox item is how dangerous lint buildup happens.
- Get multiple quotes, but compare scope, not just price. A $200 quote and a $475 quote are rarely the same job. Ask what equipment the crew uses. Rotobrush and Nikro are the tools commercial contractors rely on; a shop vac and a leaf blower aren’t interchangeable.
- Clean before a remodel, not after. If you’re renovating, getting ducts cleaned before construction dust settles in the system costs less than dealing with contaminated ductwork afterward.
- Ask about combining with a first-time inspection. An assessment tells you whether you actually need cleaning or whether the buildup is light. Not every home needs a full cleaning every year.
- Take a free estimate seriously. We’ll walk through what the system needs and give a flat number, not a vague “starting at.” Call (866) 593-7291 to schedule one.
One thing worth knowing: efficiency gains from clean ducts aren’t just theoretical. A system with airflow restored to spec runs shorter cycles and holds a cleaner filter. That’s air quality you can measure, not just feel.
FAQs – HVAC Cleaning Cost
Is $500 a reasonable price for HVAC cleaning in Sunnyvale?
Yes. A full air duct cleaning with professional equipment for a typical single-family home in Sunnyvale runs $350 – $700, and $475 – $500 is right in the middle for a single-system, 12-to-16-register home. If the quote is much lower, ask what equipment they’ll use. Call (866) 593-7291 for a free estimate and a flat quote.
How much does dryer vent cleaning cost in Sunnyvale?
Dryer vent cleaning in Sunnyvale runs $125 – $225 depending on vent length and how much lint has built up. If your vent hasn’t been cleaned in several years, expect the higher end. This is a fire-safety service, not a cosmetic one – clogged dryer vents are a leading cause of house fires. Call (866) 593-7291 to book it alongside a duct cleaning.
Is HVAC cleaning worth the money, or can I skip it?
Most homes benefit from cleaning every 3 – 5 years, and a $350 – $550 cleaning is worth it when you can see visible buildup, notice reduced airflow, or you’ve just finished a remodel. If your system is new and your ducts are clean, it’s fine to wait. A free assessment at (866) 593-7291 will tell you honestly whether you need it.
How much does duct repair cost in Sunnyvale if the cleaning finds damage?
Duct repair runs $200 – $600 for typical fixes like resealing joints, reconnecting disconnected sections, or replacing crushed flex duct. The exact price depends on how much ductwork is affected and how hard it is to reach. We give you the number before any repair starts.
Can I get HVAC cleaning done same-day in Sunnyvale?
Same-day isn’t guaranteed, but we do offer free estimates and can often fit standard single-system homes within a few days. Emergency or combined duct-and-dryer-vent jobs occasionally get same-day scheduling. Call (866) 593-7291 to check availability for your address.

What Our Customers Say
"Quoted per system rather than the bait and switch per vent pricing everybody else in town uses. The number I was told on the phone was the number on the invoice."
- Leela Shah"They photographed every return and supply before starting and sent me the file afterward. No upsell to a sanitizing treatment I didn't need."
- Karen Tran"Did the dryer vent while they were here for a small add on price. The dryer now finishes a load in one cycle instead of two."
