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.
Fast, Reliable HVAC Cleaning Across Dunedin
HVAC cleaning in Dunedin, FL typically runs $380 – $620 for a complete system clean that includes the supply and return ducts, the air handler cabinet, and the evaporator coil. Most jobs are finished in three to five hours, and you get before-and-after photos of your own ducts before the team leaves the driveway. If you’re calling about a musty smell that won’t go away or registers that keep loading up with gray fuzz, call (737) 727-2314 and we’ll give you a straight answer and a written price before anything gets touched.
We know Dunedin’s older block homes and the salt-heavy air off St. Joseph Sound better than most. That’s exactly why our HVAC Cleaning crews run Rotobrush agitation tools and Nikro HEPA extraction units instead of shop vacs, and why every job includes the air handler and coil, not just the duct runs.
Why Cardinal Air Duct Cleaning Is Dunedin’s Preferred HVAC Cleaning Company
Dunedin homeowners keep calling us back because we do the unglamorous thing: we show you the work. Every booking under The Relay Visibility Guarantee includes a live trackable arrival window, before-and-after photo documentation, and a digital invoice you can pay from your phone. No four-hour arrival vagueness, no price that shifts once the technician is inside. Omar Haddad, who runs our Dunedin scheduling, insists on one written price per system before a single register is opened, and that number does not move at the door.
We’re independently owned, part of the Relay Home Co. family that has been doing duct and HVAC work since 2005. Dunedin customers routinely tell us the same thing: the technician showed up in uniform, explained what he found in plain English, and left the house cleaner than he found it. Our crews carry Abatement Technologies containment units on jobs where we’re pulling biological growth out of a damp air handler, which matters in a city where return-side ductwork in garages and closets grows surface mold most of the year. Call (737) 727-2314 and a live person answers, day or night.
AC Coil Cleaning in Dunedin
AC coil cleaning in Dunedin means pulling the evaporator coil, cleaning the fins and the drain pan, and treating the coil with an antimicrobial product so you’re not paying for a duct clean that leaves the actual source of the smell sitting there. In Dunedin’s humidity, a dirty coil with a blocked drain pan is the single most common reason a system smells musty within weeks of a “duct only” cleaning.
A proper coil clean in Dunedin runs $180 – $280 as part of a full system clean, or on its own when the ducts are in decent shape. If the coil has heavy biological growth or the fins are matted with damp lint and dust, the work takes longer and the price reflects that in writing before we start. We always show you the coil before and after.
Why the coil matters here
Dunedin homes built between the 1950s and 1970s often have air handlers tucked into garages or closet spaces with poor airflow. The coil sits in that damp, dark environment and turns into a petri dish. Cleaning the duct runs without touching the coil just leaves the source intact.
Coil treatment, not just a rinse
After we clean the coil, we apply a coil treatment that slows mold and bacterial regrowth. It’s not a permanent fix – no product is in this climate – but it means the musty smell stays gone through a Dunedin summer instead of coming back in three weeks.
AC Cleaning in Dunedin
AC cleaning in Dunedin is a full-system service: supply ducts, return ducts, the air handler cabinet, the blower wheel, and the evaporator coil – the whole loop, not just the visible vents. A complete AC clean for a typical Dunedin home runs $380 – $620, with the final written price agreed before work starts and based on the size of the system, not the number of vents we can inflate.
We use negative-pressure extraction, which means the loosened debris gets pulled straight into the HEPA vacuum instead of drifting back into your living room. In a Dunedin block home with fifteen registers and damp return ducting, skipping negative pressure just rearranges the dust and leaves the smell exactly where it was.
Blower wheel and air handler
The blower wheel in a Dunedin AC system picks up dust, pet hair, and salt-laden lint from the coastal air. We clean it as part of the service and show you the before-and-after of that too. A clean blower wheel runs quieter and moves more air, which matters when your system is fighting 90 percent humidity in August.
Return side is not optional
Companies that price by the register count tend to skip the return ducts because they’re harder to access and no one sees them from the hallway. We clean the return side on every job. In Dunedin, where air handlers sit in garages and closets with standing humidity, the return side is usually the dirtiest and dampest part of the system.
Trusted Brands We Service in Dunedin
Our technicians in Dunedin work on most major HVAC systems and stock commonly needed filters and parts from Honeywell, Aprilaire, and Guardsman locally, so we can usually handle basic filter and fitting replacements the same day without ordering parts. We run Rotobrush rotary brush systems for agitation, Nikro HEPA vacuums for extraction, and Abatement Technologies containment units when the job involves pulling biological growth out of a damp air handler or duct liner. If the system is under a manufacturer or installer warranty, we work carefully around that and document everything with photos so you have a clean record.
Common HVAC Cleaning Problems We See in Dunedin Homes
- Damp return ducts and air handlers. Dunedin’s outdoor humidity runs 70 – 90 percent for much of the year, and block homes from the 1950s through the 1970s tend to hold moisture around the return side. Dark, damp growth on the return pan and insulation liner is the most common thing we photograph before starting.
- Salt-laden dust buildup on blower wheels and fins. Homes closer to St. Joseph Sound or the Intracoastal pick up saltier, stickier air than inland Pinellas. That dust clings to blower wheels and coil fins and resists a dry vacuum alone – it needs agitation and extraction together.
- Per-vent cleaning jobs that skip the coil and air handler. We regularly service Dunedin systems after a per-vent company cleaned the visible registers but never opened the air handler cabinet or touched the coil. The homeowner paid for a vent wipe and got the same musty smell back within a month.
- Clogged drain pans and condensate lines. With Dunedin’s humidity, a blocked drain pan overflows into the air handler area and feeds the exact conditions that cause smell and growth. We clear the pan and line during the coil service, because failing to do so just repeats the problem.
Pricing for HVAC Cleaning in Dunedin, FL

A larger two-story home or a heavily contaminated air handler with biological growth in the liner can push toward the upper end or above the range, and we’ll show you exactly why in writing before we begin.

FAQs About HVAC Cleaning in Dunedin
In Dunedin’s humidity and with the salt air, most homes benefit from a full HVAC cleaning every 2 to 3 years. Homes with pets, smokers, recent renovation dust, or air handlers in a garage or closet often need it more often – sometimes every 12 to 18 months. If the house smells musty when the system kicks on, that’s not a ventilation issue, it’s a coil or return-side problem, and waiting doesn’t fix it. Call (737) 727-2314 and we’ll help you figure out whether you actually need a cleaning now or can wait.
Per-vent pricing is the single most abused model in the duct cleaning trade. A company quotes a low per-register number, then counts every supply and return opening, adds on “deep clean” fees, and skips the air handler and coil because the math doesn’t work for them otherwise. We give you one written price for the entire system before any work starts, and it does not change at the door. Omar Haddad and the Dunedin crew price by the system, not by how many vents we can count.
Yes. Every Dunedin HVAC cleaning includes before-and-after photographs of your own ducts, air handler, and coil, taken during the job and delivered with your digital invoice. You’ll see what the return duct looked like before, what the coil looked like after, and everything in between. If we’re pulling biological growth out of a damp return pan, you’ll see that too. No photo, no claim.
Yes, always. In Dunedin, cleaning only the duct runs while leaving the coil and air handler in place is a half-job, and it’s the main reason homeowners call us after a cheap per-vent cleaning left the smell exactly where it was. The coil, blower wheel, and air handler cabinet are included in the flat system price. We also clear the drain pan and condensate line while we’re in there.
No, and we won’t pretend we do. HVAC cleaning in Dunedin is a scheduled job that takes three to five hours when it’s done properly, and a reputable crew plans for weather, parking near the air handler, and proper containment. We’ll book you for the soonest available slot with a live trackable arrival window, and a live person answers the phone at (737) 727-2314 to get you scheduled. If a company promises same-day duct cleaning, ask them how long the job takes and whether the coil is included – the answers usually explain the catch.
