AfterHow Much Does Air Duct Cleaning Cost in Jacksonville?
Air Duct Cleaning services in Jacksonville typically cost $350 to $700 for a standard single-family home, with most Jacksonville homeowners landing near $450. That covers a full negative-air cleaning of your supply and return ducts plus the main trunk lines. Larger homes over 2,500 square feet, homes with two HVAC systems, and heavily contaminated systems run higher, usually $700 to $1,100.
We give you the price in writing before we touch anything. No teases online that turn into a different number once a technician is standing in your hallway. If a company won’t put a price in writing before the work starts, that’s your signal to keep looking.
Air Duct Cleaning Cost Breakdown (2026)
Here’s what Jacksonville homeowners are actually paying in 2026. These ranges reflect our own written pricing, and they hold whether you’re in Riverside, Mandarin, or out in Orange Park.
| Service | Typical Price Range | What It Covers |
|---|---|---|
| Single-system home (up to 2,000 sq ft) | $350 – $550 | Negative-air cleaning of supply, return, and trunk lines; register and grille cleaning |
| Larger home (2,000 – 2,500 sq ft) | $450 – $700 | Same scope, more runs and registers to clean |
| Two-system home (dual HVAC) | $650 – $1,100 | Both air handlers and their separate duct networks |
| Dryer vent cleaning | $125 – $225 | Full lint removal from vent, transition duct, and exterior termination |
| Duct sealing (mastic + mesh) | $400 – $900 | Sealing accessible leaks in attic and crawlspace duct runs |
| HVAC coil and blower cleaning | $150 – $350 | Add-on to duct cleaning; cleans the evaporator coil and blower wheel |
| Mold remediation in ductwork | $500 – $1,500+ | Treatment of microbial growth, usually paired with a moisture fix |
What drives the price up: square footage, the number of systems, how accessible your duct runs are, and how bad the contamination is. What keeps it down: a single system, easy attic or crawlspace access, and cleaning done before years of buildup set in.
One term worth knowing: negative-air method means we place a machine that pulls a vacuum on the duct system while a rotary brush system breaks debris loose inside. The vacuum traps what the brush frees so it doesn’t end up in your living room. That’s the difference between real cleaning and someone vacuuming a register and calling it a day. We use equipment from Rotobrush, Nikro, and Abatement Technologies, the same gear commercial crews run.
What Affects Air Duct Cleaning Pricing in Jacksonville
- Home size and number of systems. A 1,400-square-foot bungalow in Murray Hill with one system costs less to clean than a 3,200-square-foot two-story in Julington Creek with two air handlers. More ductwork means more time and more equipment.
- Duct accessibility. Jacksonville homes are a mixed bag. If your ducts run through an accessible attic, the work moves fast. If they’re buried under insulation, boxed into a tight crawlspace, or run through a slab, that adds labor. Older homes near San Marco and Avondale often have duct layouts that were retrofitted over the decades, which slows a crew down.
- Contamination level. Jacksonville’s humidity is the real factor here. A system that’s gone 8 to 10 years without cleaning in a climate that averages 70-plus inches of rain a year tends to hold more moisture and more organic buildup. Heavier contamination takes longer and sometimes needs a follow-up treatment.
- Pets and smoking. Homes with multiple pets or indoor smoking carry more particulate in the ductwork, and pet dander tends to cling to duct walls. That’s more passes with the rotary brush.
- Mold or moisture problems. If we find microbial growth, the cleaning alone isn’t the fix. You need the moisture source addressed too, or it comes right back. That adds cost, but skipping it wastes the money you spent on cleaning.
- Add-on services. Duct sealing, coil cleaning, and dryer vent cleaning are priced separately. Bundle them and the total is usually less than booking them one at a time.
How to Save on Air Duct Cleaning
You don’t need to chase the cheapest bid. In this trade, the lowest teaser price is usually the one that moves at the door, which is why it helps to check How Much Does Air Duct Cleaning Cost in Las Vegas, NV? (2026 Price Guide) for comparison. Here’s how Jacksonville homeowners keep the number honest and still save.
- Bundle services in one visit. If your dryer vent needs cleaning and your ducts are due, booking both on the same trip saves the second trip charge. Dryer vent cleaning alone runs $125 to $225, but paired with duct cleaning it’s cheaper than two separate visits.
- Get the price in writing first. Every Hollis job gets a written price before any work starts, and it doesn’t change once we’re inside. That’s not a discount, but it’s the thing that keeps your final bill from surprising you.
- Address moisture before cleaning. If your attic ductwork sweats in the summer, fixing that first means the cleaning actually holds. Otherwise you’re paying to clean the same problem twice.
- Clean on schedule, not on emergency. Duct cleaning every 3 to 5 years costs less overall than waiting a decade and dealing with heavy buildup, mold treatment, and a system working harder than it should.
- Ask what’s included. Some quotes only cover the supply side and skip returns and trunk lines. Make sure the price covers the whole system, or a “cheap” quote isn’t cheap.

FAQs – Air Duct Cleaning Cost
How much does air duct cleaning cost in Jacksonville?
Most Jacksonville homeowners pay between $350 and $700 for a standard single-system home, with two-system homes running $650 to $1,100, while How Much Does Air Duct Cleaning Cost in Long Beach, CA? (2026 Price Guide) shows similar ranges in that market. The final number depends on square footage, the number of HVAC systems, and how accessible your ductwork is. Call (361) 326-5060 for an exact quote. Estimates are free and the price is written before any work begins.
Is air duct cleaning worth the money in Jacksonville’s climate?
Yes, and Jacksonville’s humidity is the main reason. With roughly 70 inches of rain a year and long stretches of high humidity, duct systems here collect moisture and organic buildup faster than in drier markets, so a system that goes 8 years without cleaning tends to be worse off than one in a dry climate. If your ducts haven’t been cleaned in 5 or more years, the $350 to $700 range is usually money well spent on airflow and indoor air. Call (361) 326-5060 to schedule a walkthrough and a written price.
Is it cheaper to clean the ducts or replace them?
Cleaning is almost always cheaper. A full duct replacement on a Jacksonville home typically runs several thousand dollars, often $3,000 to $8,000 depending on the layout and whether it’s a slab or attic system, while cleaning runs $350 to $1,100, comparable to How Much Does Air Duct Cleaning Cost in Los Angeles, CA? (2026 Price Guide). Replacement only makes sense when the ductwork itself is failing, crushed, or sized wrong. If the ducts are sound, clean and seal them. Call (361) 326-5060 and we’ll tell you straight which one you’re looking at.
How long does air duct cleaning take, and can you come today?
A standard single-system home takes about 2 to 3 hours, and a two-system home runs 3 to 5 hours. Same-day appointments depend on schedule, but we answer the phone live 24/7 and can often get you in quickly. Call (361) 326-5060 to check today’s availability.
What does the 365-Day Done Right Promise cover?
Every job we do is covered in writing for a full year. If the work fails within that year, we come back and make it right at no charge, including a free second visit. That’s not a vague satisfaction line. It’s a written guarantee that covers the work for 365 days. Call (361) 326-5060 to book a job that’s actually backed.
