Frequently Asked Questions

We connect a powerful vacuum to your duct system to create negative pressure, then send a rotary brush through the runs to knock dust, pet hair, and debris loose. The vacuum pulls it all into a collection unit, not back into your Gilroy living room. Every register gets cleaned, and we take photos before and after so you can see exactly what changed. The whole process on a typical home takes a few hours, and you don't need to leave the house while we work.

A standard whole-home duct cleaning in Gilroy takes about two to four hours, depending on the size of the home and how much buildup is in the system. Larger homes with long duct runs and multiple returns take longer. We'll give you a realistic time window when we schedule, based on what we see at the estimate. Fast dispatch from 7am to 7pm means most Gilroy homeowners can get on the schedule within a day or two.

Not much. Clear a path to the furnace or air handler and the return grates, and make sure the area around the main return is accessible. If you have pets, it helps to keep them in a room away from the work area during the job. We bring all the equipment, drop cloths, and everything else needed. We'll walk you through the process when we arrive and show you the before photos before anything gets turned on.

No, a properly done duct cleaning with a negative-pressure system contains the debris inside the ducts and pulls it into the collection unit outside or in a truck-mounted system. You won't have a cloud of dust settling over your furniture. We use drop cloths around registers and take care to leave your Gilroy home as clean as it was when we arrived. If a company tells you dust everywhere is normal, that's a red flag about their process.

It shouldn't be. The vacuum does the heavy lifting by pulling loosened debris out of the system as the brush works, so very little escapes into the room. We cover the area around each register, wear shoe covers, and clean up before we leave. You'll be able to walk through the house without dust footprints. Before-and-after photos of the ducts themselves will show you the work was real, not just a visual show.

Most Gilroy homes should have ducts cleaned every three to five years, more often if you have pets, allergies, or recent construction dust in the system. The South Valley's dry summers mean dust gets pulled into the HVAC system constantly, and homes near agricultural land around San Martin and Aromas tend to accumulate more fine particulates. If you've never had it done and the home is over ten years old, it's worth having us take a look. Call (833) 589-9833 and we'll give you an honest read on whether cleaning is actually needed.

We use professional rotary brush and negative-pressure vacuum systems, the same type of equipment built by brands like Rotobrush and Nikro. These are the tools built specifically for residential duct cleaning, not a shop vac with a hose attached. The brush agitates buildup inside the ducts while the vacuum pulls everything out to a sealed collection unit. This is the standard in the trade for a reason: it works, and it contains the debris.

We can install media filters and filtration upgrades while we're in your home, including units from brands like Honeywell and Aprilaire. If your system has an old 1-inch filter slot, a media cabinet upgrade means you can run a deeper filter that catches more of the fine dust that blows through Gilroy during the summer. We'll talk through options at the estimate, and you'll always know the installed price before we touch anything.

Yes, and we do it regularly. The filter media gets removed before cleaning and reinstalled or replaced afterward, depending on its condition. Homes running Aprilaire or Honeywell media filters often have cleaner ducts overall because those deeper filters catch more debris before it enters the system, but buildup still happens over time, especially on the return side. We'll check the filter during the estimate and let you know if it's due for replacement.

Every pro working under our name is required to hold the license and insurance their state requires, and the work is covered by the policies we carry. Duct cleaning in California doesn't have its own specialty contractor license, but we operate as an insured and bonded home service, which means your property is protected while we're in it. You can ask to see proof of insurance at the estimate, and we'll be glad to show it to you.

We dispatch a local team that works throughout Gilroy, Morgan Hill, Hollister, Watsonville, and the surrounding communities like San Martin, Aromas, and San Juan Bautista. Our technicians know the housing stock here, from the older ranch homes near downtown to the newer builds east of 101. A live coordinator answers the phone to get you booked, and the crew who shows up knows the streets and the seasons here. Fast dispatch from 7am to 7pm, Sunday through Friday.

In most cases, yes. We keep same-day openings for Gilroy homeowners whenever the schedule allows, especially during spring and fall when systems are switching over. Fast dispatch from 7am to 7pm, Sunday through Friday, means a morning call often turns into a same-day visit. The best way to know is to call (833) 589-9833 and ask what's open - the live coordinator will tell you right away what's available.

A live coordinator answers the phone and takes your information, then books you into the next available opening, Sunday through Friday, 7am to 7pm. We answer 24/7, so even if you call late at night, you'll speak to a real person who will get your home on the schedule. There's no voicemail tree and no waiting until the next day for a callback. Call (833) 589-9833 and you'll be talking to someone in under a minute.

No, we are closed on Saturday. Crew dispatch runs Sunday through Friday, 7am to 7pm. We answer the phone 24/7, so if something comes up on a Saturday, you can call and get booked for Sunday or the next available opening. We know some homeowners are looking for Saturday service, and we're sorry that's not a day we can offer - Sunday is available, and we'll get you in as soon as the schedule allows.

Crews are dispatched Sunday through Friday from 7am to 7pm. We answer the phone 24/7, so a call outside dispatch hours gets answered by a live coordinator and booked into the next opening - you won't get kicked to voicemail or told to call back during business hours. Early mornings and Sundays are both available if that fits your schedule better. Call (833) 589-9833 and we'll find a time that works for you.

Yes, we stand behind the work with a satisfaction guarantee. If something isn't right after we leave, call us and we'll come back and make it right. The before-and-after photos we take document what was done, so there's never a question about whether the ducts were actually cleaned. We've served Gilroy since 2011, and standing behind the work is how we've built a reputation in the South Valley.

We take before-and-after photos of your actual ducts during the job, so you see the inside of the system with your own eyes. You'll see the buildup that was there when we started and the clean metal when we finished. That's the proof, and it's specific to your home, not a stock photo from a website. If anything looks questionable, the photos are there for you to review. We want you to see exactly what your money paid for.

The work is backed by a satisfaction guarantee: if you're not happy with the cleaning for any reason, we'll come back and address it. We don't hide behind fine print or make you fight for a call back. Fifteen years in business in Gilroy, since 2011, has taught us that the only warranty that matters is the one you actually honor. Call (833) 589-9833 if anything comes up after a cleaning and the team will make it right.

No permit is required for air duct cleaning in Gilroy. It's classified as maintenance, not construction, so you won't need anything from the city's building department. If you're having ductwork modified, replaced, or added as part of a larger HVAC project, that's a different story and your HVAC contractor will handle those permits. For cleaning alone, we just show up, do the work, and you're done.

You can change your filters and vacuum the registers you can reach, but the duct runs themselves are out of reach without professional equipment. A household vacuum doesn't have the reach or suction to pull debris from a full duct run, and anything you push into the system just recirculates later. That's why we use negative-pressure systems like Rotobrush and Nikro. For a real cleaning of the whole system, it's a professional job. Call (833) 589-9833 for a free estimate and we'll show you what's actually in your ducts.
