Cost Insights
The size of your home and the type of ducts you have are the two most influential cost factors to consider.
Most HVAC pros will charge based on home size or the number of vents your system has, but some will charge by the hour.
The average home in LA is 54 years old, so there’s a good chance your tech will uncover some necessary duct repairs that drive up your total.
Los Angeles's below-average air quality can contribute to dirty air ducts, so it's ideal to schedule a cleaning every two to four years.
Air duct cleaning costs in Los Angeles average $335, and most homeowners pay between $221 and $449 for the service. Prices depend mostly on the size of your home and the layout of your ductwork, which affects how fast and easy it is to clean your system. The cost of living in LA is higher than the national average and drives up labor costs, but the moderate home size helps keep totals in check.
Air Duct Cleaning Cost Factors
Air duct cleaning in Los Angeles, CA, requires virtually no materials, so almost all of your costs will go toward labor. The size of your house, the number of vents in your system, and how accessible those vents are will drive your costs more than any other factors.
Total Square Footage of Home
The more ductwork you have, the more you'll pay for cleaning. Some local air duct cleaners base their price on the property’s square footage since the larger your home is, the more ductwork you'll have.
The cost of cleaning ductwork is $0.13 to $0.26 per square foot. The average home size in Los Angeles is just under 1,750 square feet, which is slightly below the national average. That puts normal air duct cleaning costs in LA between $260 and $530. Here’s a breakdown of the average air duct cleaning costs based on the size of your home:
| Home Size (Sq. Ft.) | Average Cost |
|---|---|
| 1,000 | $120–$215 |
| 1,200 | $155–$310 |
| 1,500 | $195–$390 |
| 2,000 | $260–$520 |
| 3,000 | $390–$780 |
Number of Vents
Some experts will charge by the number of vents your system has instead of your living space’s square footage, as each vent will require a separate cleaning process for the best results. As with ductwork, the more vents you have, the more it’ll cost to clean them. On average, vents cost $35 each to clean, with most homeowners paying between $25 and $50 per vent. To get a ballpark estimate for the cost of vent cleaning, count the vents in your home and multiply that by $35.
Most modern homes have one vent for every 100 to 150 square feet of living space. That means the average 1,750-square-foot home in Los Angeles would have between 11 and 18 vents. Pros who charge by the number of vents will likely cost between $240 and $800 in LA.
Here’s how the number of vents affects your air duct cleaning cost:
| Number of Vents | Average Cost |
|---|---|
| 8 | $170–$345 |
| 12 | $260–$520 |
| 16 | $340–$690 |
| 20 | $430–$865 |
Type of Ductwork
Four types of ducts are common in residential properties. Metal sheet ducts, fiberglass ducts, and fiberboard ducts are all equally easy and quick to clean, while the ribbed interior of flex ducts requires more time and special equipment to clean.
The average home in Los Angeles was built in 1971, right around when metal sheet ducts became the standard. If you’ve never replaced your ducts, you likely have fiberboard ducts, which are easy to clean, but the age means your tech may recommend repairs to different parts of your air ducts if they find leaks that reduce your home’s energy efficiency.
| Type of Ductwork | Average Cost |
|---|---|
| Metal sheet | $140–$450 |
| Flex | $250–$900 |
| Fiberglass/fiberboard | $195–$675 |
Labor Cost
Most ductwork pros charge by the hour, with duct cleaning services in Los Angeles priced between $130 and $180 per hour. This is significantly higher than you’d pay in most other cities because the cost of living in LA is well above the national average.
Angi Tip
If your house isn't cooling down or heating up like it used to, before calling in a pro for air duct maintenance, make sure all your vents and return vents are open and unobstructed.
Depending on the size of your home, the type of ductwork you have, and how accessible the ducts are, most cleaning jobs require three to eight hours of labor. The timeline could be longer and drive the costs higher if you need air duct repairs, too.
Accessibility
If you ensure that vents are easy to reach with vacuuming equipment, accessibility shouldn’t be a problem. But some ductwork designs make accessing them difficult, especially if you don’t have floor vents. If air duct technicians have to work harder or take additional steps to reach your vents, it can result in additional labor charges. You can help keep costs down by ensuring your air vents aren’t blocked before your tech arrives.
Inspections
Some vent problems, like noticeable mold or nests, don’t require an inspection before cleaning. However, if you aren’t sure about the state of your vents, consider arranging a professional inspection. These inspections are often bundled together as part of an HVAC inspection, which costs an average of $300 but can fall under $100 for simple systems.
Level of Cleanliness or Contamination
Duct cleaning is offered as a package with set labor costs, but extremely dirty jobs will cost extra. If the ducts have never been cleaned and need a lot of work to remove dust and buildup, expect additional fees.
Los Angeles has some of the highest pollution rates of any major city in the country, and the high air quality index ratings mean you should schedule duct cleaning a bit more frequently than you might in other cities. Aim for every two to four years, and expect to pay a little above the local average if it has been significantly longer since your last service.
Air Duct Cleaning Pro Costs
Labor accounts for between 90% and 95% of your total, so when you hire an air duct cleaning company in Los Angeles, you can expect between $300 and $320 to go toward labor alone. The high cost of living in LA leads to higher hourly rates, although most jobs require less time than average due, in part, to below-average property sizes.
Hiring a pro means you’ll also have to account for sales tax. The sales tax rate in LA is 9.75%, including state and city taxes, so expect to pay an average of $32.66 in sales tax.
Does Air Duct Cleaning Increase Home Value?
Air duct cleaning won’t increase your home value, as it’s a very affordable service, it doesn’t contribute to your home’s visual appeal, and it’s considered routine maintenance rather than an improvement. However, noting that you recently had a professional service completed may be a minor selling point for a buyer, especially since LA is known for poor air quality.
The benefits of air duct cleaning are mostly health-related rather than financial. Clean air ducts reduce the risk of allergy symptoms and worsening respiratory issues for you and your family, and they make your home a healthier place to live, in general.
