Aprilaire Air Duct Cleaning in Long Beach: What to Know First
We’re Hollis Air Duct Long Beach, and we clean the ductwork that moves air through Aprilaire systems in homes across Long Beach. Most Aprilaire air duct cleaning jobs take one visit, four to six hours, and run between $425 and $780 depending on the size of the home, the number of returns, and how long it has been since the ducts were last touched. The price is written down before we start, and it does not move at the door. This page is for Long Beach homeowners who own an Aprilaire system, want the ducts cleaned correctly, and do not want a long sales pitch attached to the work.
If you already know you want the job done, call (562) 548-7365 and we’ll give you a straight answer on scheduling and cost.
How Aprilaire Products Fail – and How We Fix Them
Aprilaire builds filtration and humidity control equipment, not ductwork, but the two work as one system. When the ducts are dirty, an Aprilaire filter loads faster, an Aprilaire humidifier has to work harder, and an Aprilaire thermostat can read the room wrong. Here is what we see on Aprilaire-equipped homes in Long Beach:
- Aprilaire 213 and 413 replacement filters loading too fast. When the return ducts are carrying dust from a 30-year-old attic chase, a fresh MERV 11 or MERV 13 Aprilaire filter can load up in four to six weeks instead of nine to twelve. We clean the return side first, then the supply runs, because the return is what feeds the filter. The fix is not a cheaper filter. The fix is cleaner ducts behind it.
- Aprilaire 700 and 400 series humidifiers with mineral crust breaking off into the plenum. Long Beach water is moderately hard, and that calcium ends up on the water panel and inside the humidifier cabinet. If the ducts have not been cleaned in years, that crust mixes with normal dust and forms a paste that sticks to the supply runs. We remove and flush what we can reach, replace the water panel if needed, and clean the supply ducts with a rotary brush system, not just negative air.
- Aprilaire 5000 electronic air cleaners arcing and snapping when the ducts are loaded. The 5000 charges airborne particles so they collect on its plates, but fabric fibers and pet hair that make it past the pre-filter can bridge the plates and cause a popping sound. We clean the 5000 cabinet and also clean the ducts feeding it. If you have heard snapping from the unit, the ductwork behind it is part of the reason.
- Flex runs sagging and collecting debris in Long Beach attics. This is less about Aprilaire and more about the house. In older Long Beach tracts with flat roofs, attic temperatures run high, and flex duct sags between straps. That sag becomes a low point where dust settles. We inspect the runs, re-strap where needed, and clean what was trapped.
- Return air pulled from hot attics instead of the house. A disconnected return boot or a cracked plenum turns your Aprilaire system into an attic vacuum. The system pulls hot, dusty air from outside the envelope, and the Aprilaire filter becomes the last line of defense. We find and seal those gaps with mastic before we finish the cleaning, because cleaning ducts that are pulling attic air would be pointless.

Our Aprilaire Air Duct Cleaning Process
Here is what happens on a typical Aprilaire air duct cleaning job in Long Beach, from the first call to the final walkthrough:
- 1
Inspection and written price. We look at the system, count the ducts and returns, and check what Aprilaire equipment is installed. You get a written price before any work begins.
- 2
Protection and negative air setup. We seal off registers, lay floor protection, and connect our negative-air machine to create airflow that carries loosened debris out of the system.
- 3
Return-side cleaning first. We clean the return plenum and return ducts, then replace or clean the Aprilaire filter housing as needed. This is the side that feeds your filter.
- 4
Supply-side cleaning with a rotary brush. We run a Rotobrush system through each supply run, breaking loose years of compacted dust that negative air alone would leave behind.
- 5
Video verification. We show you before-and-after images from inside your own ducts. If something is not clean, we do not sign off on it.
- 6
Clean site and written record. Each register is wiped, the drop cloths come up, and we walk you through what was done. The job is covered by our 365-Day Done Right Promise in writing.

AfterWhat Aprilaire Air Duct Cleaning Costs in Long Beach
We quote the whole system, not a per-vent teaser price that balloons once we arrive. For most single-family homes in Long Beach with a single Aprilaire system, here is what to expect:
- Small homes, 6-10 vents: $425 to $560
- Average homes, 10-16 vents: $525 to $680
- Larger homes, 16-25 vents, multiple returns: $650 to $780
What moves the price: the number of return drops, whether the home has two systems or one, how badly the ducts are loaded, and whether we find leaks that need sealing. Duct sealing mastic work is quoted separately, in writing, before we touch it. You will not find a lower teaser price followed by a surprise at the van. Call (562) 548-7365 for a free estimate and we will give you the real number for your home.
Why Long Beach Homeowners Call Hollis Air Duct Long Beach for Aprilaire Work
We have served Long Beach for years, and we have seen every kind of duct system the city throws at a crew. Roy Castellanos grew up in East Los Angeles and came up through the HVAC program at East Los Angeles College, then spent years working on everything from old asbestos-wrapped trunks in 1950s builds to the flex work common in newer tracts. That experience means we do not panic when we find an odd transition or a return boot crushed in an older wall.
Every job gets a written price before we start. Every technician who walks into your home is background-checked and uniformed. Every job is covered by the 365-Day Done Right Promise, which means if the work fails within a year, we come back at no charge and complete a second visit free. We also work on systems from Lennox, Trane, and Carrier, so if your Aprilaire system shares a closet with another brand’s air handler, one crew handles all of it.
FAQs
Yes. Air duct cleaning does not void an Aprilaire equipment warranty. We are an independent Aprilaire service provider and do not modify, tamper with, or bypass any Aprilaire component. We clean the ducts, the filter housing, and accessible plenums, and we follow the manufacturer’s clearance and access guidelines on every job. If we see something that belongs to the Aprilaire warranty, we tell you about it before we touch it.
In Long Beach, every four to six years is a reasonable interval for most homes. The city’s coastal air carries fine particulate, and older homes built before 1980 often have duct runs that collect it faster. If you run an Aprilaire humidifier or 5000 electronic air cleaner, check the ducts every three to four years because those systems put more demand on the airflow. Call (562) 548-7365 if you are not sure your ducts are due and we will tell you straight.
Because they are counting on the upsell once the van is at your house. A low per-vent price gets the appointment, then the technician finds “mold,” “pests,” or “leaks” and the invoice triples. We quote the whole system in writing. One flat price per system agreed before work starts. If that makes us a little more expensive on the front end, it also makes us a lot less expensive once the job is done.
Yes. We handle commercial duct cleaning for Long Beach businesses that run Aprilaire filtration on their HVAC systems, including restaurants, offices, and medical suites. Commercial jobs are quoted per system, not per vent, and the same 365-Day Done Right Promise applies. Call (562) 548-7365 with building size and system count for a free estimate.
We show you before-and-after video from inside your own ducts, not a stock photo. Roy’s standard is the same one he has enforced since he started: the airflow leaving a job has to be measurably cleaner than what he found, and he will not sign off until it is. Clean ducts aren’t a luxury – they’re just what the system needs to do its job. You will see the difference before we leave.
We focus on the ductwork, the filter housing, and the plenums. We do not sell or install Aprilaire units, and we are not an authorized Aprilaire dealer. If your Aprilaire humidifier, thermostat, or air cleaner needs manufacturer warranty work, we will point you to the right place. What we do is make sure the air moving through your Aprilaire system starts clean and stays that way.
If you own an Aprilaire system in Long Beach and haven’t had the ducts cleaned in years, call Hollis Air Duct Long Beach at (562) 548-7365 for a free estimate. We’ll give you a written price, show you what’s inside your ducts, and stand behind the work in writing for a year.
