Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

Why Cardinal Air Duct Cleaning Is Longwood’s Preferred HVAC Cleaning Company
Longwood homeowners call us because we name our price before we touch a duct, and that price doesn’t move once the technician is in your home. We’re part of the Relay Home Co. family, founded 2005, and every booking runs on The Relay Standard: a live trackable arrival window, background-checked technicians in uniform, before-and-after photos of your own system, and a digital invoice payable from your phone. No four-hour wait windows. No mystery charges.
Omar Haddad leads our team, and the 365-Day Done Right Promise is his standing rule on every job: if the work isn’t right within a full year, we return and correct it at no charge. That’s not a promo. It’s our standard.
Our crews respond to Longwood from the South FL dispatch office, and most cleanings are scheduled within a few days, not weeks. We carry Rotobrush agitation systems and Nikro HEPA-rated negative-pressure vacuums, so the debris comes out of your ducts and into our containment, not back into your living room.
AC Duct Cleaning in Longwood
AC duct cleaning in Longwood means removing the buildup from your supply and return lines, the air handler cabinet, the evaporator coil, and the blower motor. In this climate, a system runs hard from March through October, and that’s 8+ months of dust, pet dander, and lint moving through your ductwork every single day. Longwood’s older homes, especially the 1970s ranch stock near the Casselberry line and the established neighborhoods around Springs Landing, often have original sheet-metal trunk lines with undersized returns. We frequently find the heaviest buildup packed at the air handler rather than at the registers.
A full AC duct cleaning for a typical Longwood home runs $380 – $680, one flat price per system agreed before work begins. No per-vent pricing, no bait-and-switch coupon that becomes a bigger invoice. You’ll see the before-and-after photos of your own ducts before you pay.
Evaporator Coil Cleaning
Your evaporator coil sits above the air handler and pulls moisture out of Florida’s humid air. Over time, it collects a biofilm of dust and condensate that reduces cooling efficiency and pushes allergens through the house. We clean the coil in place, treat it, and document the result.
Blower Cleaning
The blower motor wheel is where Longwood systems hide their dirt. On older trunk-line homes, we regularly see blower wheels caked with a decade of lint that never made it to the registers. We remove, clean, and reseat the blower assembly as part of the full system price.
Furnace Cleaning in Longwood
Furnace cleaning in Longwood is a shorter season job, but it matters here more than people think. North-central Florida gets genuinely cold snaps in January and February, and when a furnace kicks on for the first time in months, it burns off a summer’s worth of dust and lint that settled in the heat exchanger and burner compartment. That’s the smell Longwood homeowners notice when the heat first comes on.
A furnace cleaning runs $120 – $250 when bundled with a full duct cleaning, or as a standalone job depending on the unit. We inspect the heat exchanger, vacuum the burner area, check the pressure switch, and clean the blower. If we find a cracked heat exchanger, we stop and tell you before anything gets worse. This is combustible-gas equipment, so we flag any safety concern immediately.
Heat Exchanger Cleaning
The heat exchanger transfers flame heat to your air without mixing combustion gas into the house. Dust and debris on it reduce efficiency and can produce that burning smell on first fire-up. We clean and inspect it, and we photograph the condition before and after.
Air Handler Cabinet Cleaning
The air handler cabinet is the box that houses the coil, blower, and filter. On Longwood’s older homes, this cabinet is where lint, dust, and sometimes construction debris from past renovations collects. We clean and sanitize the full cabinet as part of every system-level job.
Trusted Brands We Service in Longwood
Longwood homes run on all major equipment brands, and our techs service units from Carrier, Trane, Rheem, Goodman, and Lennox. We stock common OEM filters, Aprilaire media, and Guardsman antimicrobial treatments locally for fast turnaround. We run professional-grade equipment including Rotobrush rotary brush systems and Abatement Technologies containment units. If your system uses ultraviolet light, media filtration, or a whole-home dehumidifier, we service those too. Mention your brand when you call and we’ll confirm the parts we carry for it.
Common HVAC Cleaning Problems We See in Longwood Homes
- Lint packed at the air handler on 1970s ranch homes. Those original sheet-metal trunk lines with undersized returns don’t move air the way modern systems do. Lint and dust settle right at the blower and coil instead of pushing through to the registers.
- Per-vent quotes that don’t reflect the actual work. A Longwood home with 16 vents might have far heavier air-handler buildup than a 22-vent home in a newer build. Vent count tells you nothing about labor. One flat price per system does.
- Contractors skipping negative pressure and HEPA filtration. Without both, so-called cleaning just stirs debris around and redeposits it. Source removal requires the loosened debris to go straight into the vacuum, not into your living space.
- Musty smell traced to a packed return trunk, not the registers. We ran a camera inspection at a Springs Landing home with a 1978 ranch layout and found decades of lint lining the return trunk and a partially blocked blower. The airflow felt noticeably stronger after source removal and air-handler sealing.

FAQs About HVAC Cleaning in Longwood
Every 3 – 5 years for most Longwood homes, but it genuinely depends on what we find. Homes with pets, recent renovations, or smokers should lean toward every 3 years. Newer construction off Wekiva Springs Road may not need it for 5+ years. If you call us and an inspection shows your ducts are actually clean, we’ll tell you to save your money. Call (737) 727-2314 for an honest assessment.
One flat price per system, always. We quote it in writing before any work starts, and that number does not change at the door. Per-vent pricing is how bait-and-switch operators hook Longwood homeowners with a low coupon and then inflate the invoice once they’re inside. We don’t do it.
Yes. Every Cardinal Air Duct Cleaning job includes before-and-after photos of your own ducts, coil, blower, and air handler. You see exactly what we cleaned and what it looked like before. That’s the before-and-after photo documentation built into The Relay Standard. Call (737) 727-2314 and ask us about it.
Not always, and we won’t promise it to get the booking. Most Longwood cleanings are scheduled within 2 – 5 days. We’d rather schedule the time right and do the job to NADCA standards than rush a partial cleaning. A live person answers the phone 24/7 at (737) 727-2314, so call and we’ll find the next available slot that works for you.
NADCA is the National Air Duct Cleaners Association, and its standard requires source removal, not just surface brushing: the debris must be physically extracted from the system using negative pressure and HEPA filtration, and the entire HVAC system, including the air handler, coil, and blower, must be addressed, not just the visible registers. Our process follows NADCA’s ACR standard. If a contractor only pokes a vacuum into your registers, that’s not cleaning. Call (737) 727-2314 for a free estimate that meets the standard.
