Air Duct Cleaning Specials in Hempstead, NY
Hollis Air Duct Hempstead runs a short list of standing offers because most people put off duct cleaning until the dust is visible on the registers. That’s the wrong time to pay full price for it. Call (516) 559-4917, tell us which offer fits your house, and you’ll get a written price before any work starts. No bait pricing, no surprises at the door.
Current Offers
Free Estimate on Any Whole-System Air Duct Cleaning
We walk the system, check the return, the supply trunk, and a few branch runs, then hand you a written price. That price covers the entire system and it does not move once the truck is in your driveway. No per-vent add-ons, no equipment fees invented at the register.
Valid through March 31, 2027. Mention this offer when you call (516) 559-4917.
First-Time Customer Courtesy: Free Dryer Vent Inspection With Any Duct Cleaning
If you’ve never used Hollis Air Duct Hempstead before, we’ll inspect your dryer vent run while we’re already on site for the duct job. Built-up lint in a dryer vent is a fire waiting for a load of towels. You’ll know exactly what’s in there before we recommend any work.
Valid through March 31, 2027. Mention this offer when you call (516) 559-4917.
Senior and Military Courtesy Discount
A standing thank-you for the people who’ve paid enough dues. Mention it when you call and we’ll take a courtesy amount off the written quote, no verification forms beyond a simple ID at the door. It applies to air duct cleaning, dryer vent cleaning, and duct sealing.
Valid through March 31, 2027. Mention this offer when you call (516) 559-4917.
Seasonal Tune-Up: Pre-Winter Visual Inspection of Duct Seams and Registers
September through November in Hempstead, we run a seasonal inspection special for homes that haven’t had their ductwork looked at in five years or more. We check visible seam separation, loose registers, and return-side gaps that pull attic or basement air into the system. You get a plain-English write-up of what we found, whether or not you book the repair.
Valid through March 31, 2027. Mention this offer when you call (516) 559-4917.
Duct Sealing Add-On at a Reduced Rate With Any Cleaning
If your system is already open and we’re running the Rotobrush through it, sealing accessible seams and connections costs less as an add-on than booking it as a separate visit. Duct sealing mastic closes the gaps where conditioned air bleeds into the attic or crawl space. The written quote will show the cleaning price and the sealing price as separate lines, so you know what each one costs.
Valid through March 31, 2027. Mention this offer when you call (516) 559-4917.
365-Day Done Right Promise on Every Job, Offer or Not
This one isn’t a coupon. It’s the standing guarantee on everything we do in Hempstead, from Uniondale to West Hempstead to Garden City South. Every repair and installation is covered in writing for a full year. If the work fails, Hollis Air Duct Hempstead returns at no charge, including a free second visit. The offer is just the reason to call; the guarantee is the reason to stay.

How to Redeem
Three steps and you’re done. First, call (516) 559-4917 and tell the live person which offer applies to you. We answer phones around the clock, so you’re not leaving a message and hoping for a callback. Second, book the visit. Every slot comes with a quoted arrival window under The Garrison Code, and the technician shows up in uniform with a background check on file. Third, present the offer at the time of service. We apply it to the written quote before you sign anything. You’ll see the final number on paper, in plain English, before the equipment comes off the truck.
Why Hollis Air Duct Hempstead Runs Offers This Way
We’ve been cleaning ducts in Hempstead since 2004, and the industry’s reputation for coupon games is the first thing homeowners mention when they call. A $79 whole-house special that becomes $800 at the door. A per-vent price that quadruples once the technician counts the registers. We don’t do that. The offers on this page are discounts on honest, written, whole-system pricing. The dollar range you hear on the phone is the dollar range you pay. Roy Castellanos, the owner, put the 365-Day Done Right Promise on every job in writing because the alternative is a business built on rework and apologies. That’s not a way to run trucks in Nassau County.

AfterWhat This Works Out To in Real Terms
Air duct cleaning in Hempstead typically runs between $350 and $600 for a whole system, depending on the size of the house, the number of returns, and how long it’s been since the last cleaning. A dryer vent run is usually $125 to $200 as a standalone service. Duct sealing varies more, but accessible-seam sealing on a typical Hempstead colonial is generally $400 to $900. These aren’t quotes, they’re the ranges we see across the homes we service regularly. When you call (516) 559-4917, you’ll get a written price for your specific system, with any offer applied, before you commit to anything.
What the Equipment Actually Does
We run Nikro negative-air machines that put the ductwork under vacuum while the Rotobrush rotary system scrubs the interior walls. The negative-air setup means the dust we dislodge gets pulled into the machine’s HEPA filtration, not blown into your living room. If we’re adding filtration, we stock Honeywell, Aprilaire, and Abatement Technologies products. If we’re sealing, we use mastic, not tape, because tape dries and peels while mastic hardens. These are the same tools commercial crews use, and they matter more than the coupon amount.
Frequently Asked Questions
Yes. The offer needs to be on the books before that date. If you call (516) 559-4917 before the end of March and schedule the visit for a few weeks out, the offer still holds. We don’t play calendar games with the fine print.
Generally no. The senior and military courtesy can stack with the seasonal tune-up, but the rest are standalone offers. When you call (516) 559-4917, tell the person on the phone everything that applies to you and they’ll tell you exactly which combination works best.
That’s the 365-Day Done Right Promise. If the repair or installation fails within a year, we come back at no charge. That includes a free second visit. It’s in writing on every job, not just the ones with a coupon attached. Call (516) 559-4917 and we’ll schedule the return.
Because they’re not whole-system quotes. A low number usually covers a set number of vents, with a per-vent charge for everything beyond that. Or it’s a sale price that excludes the return side, the trunk line, or the plenum. By the time the technician leaves, the invoice doesn’t look anything like the ad. Our quotes are written for the entire system, line by line, before work starts. The price on the paper is the price you pay.
Ask for before-and-after photos of your own ducts. We take them on every job, specifically the return side and a few branch runs, because the return is where Hempstead homes accumulate the most dust in summer when the AC runs constantly. You’ll see the same section of duct from the same angle, before and after. If a company can’t show you that, you didn’t get the job you paid for.
Every four to six years for most homes, sooner if you have pets, recent renovations, or smokers in the house. Homes near the Southern State or Hempstead Turnpike tend to accumulate faster because of the road dust and pollen drawn into the return. If you can’t remember the last time anyone looked inside the ducts, that’s your answer. Call (516) 559-4917 for a free estimate and we’ll tell you what’s actually in there before you decide.
