Why Pasadena Homeowners Choose Carrier Air Duct Cleaning
We provide independent Pasadena Carrier service for air duct cleaning, working on Infinity, Performance, Comfort, and WeatherMaker systems every week. Our approach is built around how Carrier air handlers actually pull air through older Pasadena ductwork, which matters because a 1930s Craftsman with original galvanized ducts behaves nothing like a 2015 tract home when a Carrier blower spins up. We’re not authorized by Carrier, and we’ll tell you that straight, but we know these systems cold. Call (626) 469-5477 when your Carrier system needs duct work done right.

Why Trust Hollis Air Duct Pasadena for Your Carrier Air Duct Cleaning?
Roy Castellanos and our crew have cleaned duct systems in Pasadena for over a decade, including plenty of older homes near the Rose Bowl that haven’t had their ducts touched since the Reagan administration. Roy learned the mechanical side of HVAC at Los Angeles Trade-Technical College, then spent years doing hands-on duct cleaning before going out on his own. He’ll tell you straight: the duct work doesn’t lie, and neither does he.
On Carrier jobs, that matters. We know where Infinity air purifier media sits in the cabinet, and we remove it before cleaning so we don’t blow a cloud of captured dust back into your supply runs. We know what static pressure readings mean for an Infinity variable-speed blower versus a Comfort Series single-speed. And we know what Pasadena’s older ductwork does to Carrier filter performance when years of remodel dust and pet hair pack into the return side. On every Air Duct Cleaning services job we do in Pasadena, we follow The Garrison Code: arrive inside the quoted window, put the price in writing before we touch anything, complete the job by the book, and leave the site cleaner than we found it. Every job is covered by our 365-Day Done Right Promise, in writing. If our work fails within a year, we come back at no charge, including a free second visit. That’s not a slogan. That’s the standard. Call (626) 469-5477 to schedule your Carrier air duct cleaning in Pasadena.

Common Carrier Air Duct Cleaning Problems We Fix in Pasadena
- Infinity air purifier media clogged with dust and construction debris. On Infinity Series systems in Pasadena, the factory media sits inside the air handler cabinet. When remodel dust from a Bungalow Heaven renovation gets past a marginal filter, it packs into that media and chokes the high-efficiency blower. We remove the media before cleaning so it doesn’t send a dust burst into the supply ducts, then we vacuum the cabinet interior and install fresh OEM-grade media.
- Return ducts packed with lint and pet hair on higher static pressure older homes. Pasadena’s housing stock is dominated by single-family homes built between 1900 and 1940. Original ducts are often galvanized steel, undersized by modern standards. Carry that higher static pressure over to a variable-speed Infinity blower, and it pulls harder on the return side, accumulating lint and pet hair faster. We clean those returns with a rotary brush system and negative-air extraction so the debris is captured, not recirculated through your Carrier air handler.
- Mold on evaporator coils where Pasadena humidity hits under-insulated ducts. Comfort Series systems in older Pasadena homes frequently show evaporator coil mold growth. The cause is condensation forming on cold coil surfaces where crawlspace and attic ducts lack adequate insulation, giving mold a damp, dark place to thrive. We clean the coil with professional-grade cleaners and drying procedures, then address the duct insulation so the problem doesn’t return with the next warm season.
- Blower wheel imbalance from accumulated debris on variable-speed Infinity motors. Infinity variable-speed blowers are quiet and efficient, but they’re sensitive. When accumulated debris builds up unevenly on the wheel, it creates vibration that wears the motor bearings over time. We remove the blower wheel, clean it properly, and check for cracks or damage before reassembling. Catching this early saves you a far more expensive Infinity motor replacement.
- Leaky duct boots discovered during video inspection. Not every Carrier problem is inside the air handler. In many Pasadena character homes, boots have separated from the floor registers or wall stacks after decades of settling. Air your Carrier system paid to condition leaks into the crawlspace instead. After video inspection confirms the failure, we apply mastic sealant to restore a proper seal at every leaking connection.
Carrier Parts & Our Repair-vs-Replace Approach
When Carrier air duct cleaning in Pasadena requires component replacement, we use OEM-grade filters, gaskets, and access panels. For standard Carrier filter media, we recommend quality aftermarket media that meets the same MERV rating at a lower cost. We never upsell you into parts you don’t need. If cleaning and sealing restore proper airflow, we say so. If a Carrier blower wheel is cracked or a coil is too far gone to save, we’ll tell you that too, with a written price before any replacement work starts. Our decisions are based on what the system actually needs, not what pads the invoice. Call (626) 469-5477 for an honest assessment. Estimates are free.
Our Carrier Service Process – Step by Step
- 1
Diagnosis. We inspect the full system, including the Carrier air handler cabinet, return and supply ducts, filter media, and accessible coil surfaces. On Infinity systems, we check static pressure readings before and after. If video inspection will confirm a suspected issue, we run it on the spot.
- 2
Cleaning or repair. We remove contaminants from ducts, clean blower wheels and coils where needed, and replace worn gaskets or media with OEM-grade parts. For leaking ducts, we apply mastic sealant to restore proper airflow. No work starts until you’ve seen the written price and approved it.
- 3
Verification. We test airflow, measure static pressure where the system allows it, and visually confirm registers are clear. If anything reads out of spec, we address it before we call the job done.
- 4
Warranty. Every Carrier job receives our 365-Day Done Right Promise in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit. That’s the whole promise, not a partial one.

FAQs – Carrier Air Duct Cleaning Service in Pasadena
No. We are an independent Carrier air duct cleaning and service provider in Pasadena. We have no authorization or affiliation with Carrier. What we have is over a decade of hands-on experience with Carrier Infinity, Performance, Comfort, and WeatherMaker systems in Pasadena homes, and we’re straightforward about that distinction because it keeps our advice honest.
We use OEM-grade filters, gaskets, and access panels where component replacement is required during duct cleaning. For standard Carrier filter media, we recommend quality aftermarket media that meets the same MERV rating at a lower cost. We’ll always explain what you’re getting and why before any part goes in. Call (626) 469-5477 for a free estimate on your Carrier service.
Most complete Carrier air duct cleaning jobs in Pasadena take four to six hours, depending on the home’s size, number of returns, and duct condition. A single-story bungalow with short runs typically goes faster. A two-story home with hard-to-reach returns and decades of accumulation takes longer. We’ll give you a written time estimate before work starts, and we arrive inside our quoted window.
Yes, if restricted airflow is the cause of the problem. When ducts are clogged, the condenser can’t move enough air across the coil, and cooling drops off. In our experience with Pasadena homes, clearing return and supply restrictions often restores several degrees of comfort. We measure static pressure before and after on Infinity systems so you can see the difference in numbers, not just feel it. Call (626) 469-5477 for an exact quote on your Carrier air duct cleaning.
Only if the coil itself is cleaned as part of the job. Duct cleaning alone won’t remove mold or mildew growing on the coil surface. In Pasadena’s older homes, where under-insulated ducts create condensation problems, coil cleaning is often the actual fix. We clean the coil with professional-grade cleaners and drying procedures, then address the duct insulation so the problem doesn’t come back. If you’re smelling mildew from your Carrier system in Pasadena, call (626) 469-5477 and we’ll diagnose it.
A full Carrier air duct cleaning in Pasadena typically runs $450 to $900, depending on home size, number of returns, and access difficulty. Coil cleaning adds $150 to $300. Duct sealing adds $200 to $500 depending on how many connections leak. You’ll get one flat price per system in writing before any work starts, and that price does not move at the door.
