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 Middleburg’s Preferred HVAC Cleaning Company
We’ve cleaned enough Middleburg ductwork to know that this town has its own particular problems. The 1970s through 1990s brick ranches that line Blanding Boulevard and the shaded streets off Henley Road were built for a different climate reality, and their duct runs often snake through unconditioned attic space where Florida humidity does real damage. We don’t work from a generic playbook. Each job starts with a camera inspection of your actual supply and return runs, and you get before-and-after photos of your own ducts, not someone else’s.
Our technicians are background-checked, uniformed, and they run professional-grade equipment built for real source removal: Rotobrush rotary brush systems to agitate built-up debris and Nikro HEPA-rated vacuums to pull it out under negative pressure. That means the loosened dust, pet hair, and construction debris goes into our containment unit, not back into your living room. We’re part of the Relay Home Co. family, founded in 2005, and every Middleburg job carries The Relay Standard: a live trackable arrival window, photo documentation, and a digital invoice you can pay from your phone before we leave the driveway.
Omar Haddad leads our Middleburg service area, and when you call (737) 727-2314, a live person answers. No voicemail loops. No callbacks next Tuesday. You’ll know your technician’s name before they ring the doorbell, and the price they quote is the price you pay.
Here’s what every Middleburg booking includes:
- One flat price per system, written down before any work starts
- Before-and-after photos of your own ducts and coils
- The 365-Day Done Right Promise: if it’s not right within a full year, we return and correct it at no charge
- A written guarantee on every repair, plus a free second visit if that repair fails
AC Coil Cleaning in Middleburg
AC Coil Cleaning in Middleburg homes is one of the highest-impact services we perform, because this town’s humidity and pollen load coat evaporator coils fast. When the coil inside your air handler gets a layer of grime, your system can’t pull heat from the air efficiently. The result: longer runtimes, higher electric bills, and a house that stays sticky even while the AC never shuts off. A proper coil cleaning in Middleburg typically runs $150 – $300 as part of a broader HVAC Cleaning package, and we always quote the coil work separately so you see exactly what you’re paying for.
Evaporator Coil Cleaning in Middleburg
The evaporator coil sits inside your air handler, usually in a closet, garage, or attic. In Middleburg’s humid climate, this coil develops a biofilm of dust and moisture within two to three years. We open the air handler, photograph the coil before we start, apply an appropriate coil cleaner, and finish with a rinse that drains properly. You see the photos afterward. If the coil is too far gone, we’ll tell you honestly rather than selling a cleaning that won’t help.
Condenser Coil Cleaning in Middleburg
Your outdoor condenser coil takes abuse from Middleburg’s sandy soil, lawn clippings, and the pollen that blows through every spring. A clogged condenser coil forces the compressor to work harder and shortens its life. We wash the fins, straighten any bent ones, and check the refrigerant line insulation while we’re there. This typically adds $75 – $150 to a full-system cleaning, depending on how much buildup we find.
AC Cleaning in Middleburg
AC Cleaning in Middleburg means more than spraying a coil and calling it done. A real cleaning addresses the entire airflow path: the return and supply ducts, the air handler interior, the blower motor and wheel, and both coils. Most standard 3 – 4 bedroom Middleburg homes run $350 – $600 for a complete AC cleaning, with one flat price agreed before we start. That single price protects you from any surprises when we count registers, because Middleburg homes often have converted garages or added Florida rooms with extra supply runs that a per-vent quote would penalize you for.
Blower and Air Handler Cleaning in Middleburg
Your blower wheel and air handler cabinet collect a layer of gray fuzz that reduces airflow and sends it back through your house. We remove the blower assembly, clean the wheel and housing, and vacuum the cabinet interior. In Middleburg’s older ranch homes, the air handler is often tucked into a tight closet or low attic, so this part takes patience and the right tools. We have both.
Heat Exchanger and Coil Treatment in Middleburg
Heat exchangers in gas furnaces around Middleburg’s older homes need inspection and cleaning, especially if you run heat on those occasional cold January mornings. We brush and inspect the exchanger, then apply a coil treatment that slows future buildup. Coil treatment is an add-on that typically runs $50 – $100, and we’ll show you the before-and-after so you know it was actually done.
Trusted Brands We Service in Middleburg
Middleburg homes run a wide mix of equipment brands depending on when they were built. We service and clean systems from Carrier, Trane, Rheem, Goodman, Lennox, and American Standard, and we stock common filters, coil cleaners, and replacement parts locally so your job doesn’t stall waiting on a shipment. We also install and recommend filtration products from Honeywell, Aprilaire, and Guardsman when a Middleburg home needs better particulate capture between cleanings. Our containment and extraction setup includes Abatement Technologies negative air machines, which matters if your ducts run through a crawlspace with mold or heavy rodent activity.
Common HVAC Cleaning Problems We See in Middleburg Homes
- Rusted-through supply trunks in crawlspaces. Many Middleburg homes from the 1970s and 80s sit on open crawlspaces rather than slabs, and the metal ductwork down there rusts in the humidity. A camera inspection finds leaks, and sealed or replaced sections stop you from paying to cool the crawlspace.
- Rodent damage near the air handler. Black Creek and the wooded lots throughout Middleburg mean rats and squirrels find their way into attic duct runs. We’ve found chewed flex returns and nests built inside return plenums. We’ll show you the photos and fix what’s fixable before cleaning.
- Clogged returns in low ranch attics. The return ducts in older Middleburg ranches are hard to reach, so some companies skip them. That’s where the heaviest buildup lives. We don’t skip them.
- Short-cycling and gritty registers. When we hear a Middleburg homeowner describe a system that kicks on and off constantly and blows grit onto furniture, we know what we’re usually going to find: a collapsed flex run or a blower wheel so caked with dust that airflow has dropped to a fraction of the system’s rating.
Pricing for HVAC Cleaning in Middleburg, FL
Here’s what honest pricing looks like in Middleburg. A standard AC coil cleaning runs $150 – $300. A complete AC cleaning with ductwork on a 3 – 4 bedroom home runs $350 – $600. A full duct replacement or major repair is quoted separately after we show you the camera footage of why it’s needed. The biggest variable in Middleburg is whether your home has a crawlspace, because duct access changes the job. We never charge per vent. You get one flat price per system, written down before we start, and that price does not change at the door. Call (737) 727-2314 for a free estimate on your specific home.

FAQs About HVAC Cleaning in Middleburg
Most Middleburg homes need a full HVAC cleaning every 3 to 5 years. Homes with pets, smokers, recent renovations, or crawlspace ductwork should lean toward 2 to 3 years. If your home is only a few years old and you change filters regularly, a cleaning may not be needed yet. We’ll tell you if yours isn’t due. Call (737) 727-2314 and we’ll help you decide based on what your system actually shows, not a marketing schedule.
We charge one flat price per system, agreed before we start, and it never shifts based on how many vents we count. Middleburg homes often have added-on Florida rooms and converted garages with extra supply runs, and a per-vent quote punishes you for those. Your written price is final. Call (737) 727-2314 for an exact quote on your system.
We start with a camera inspection of your supply, return, and air handler. Then we set up negative-pressure extraction with HEPA filtration, meaning the debris we loosen goes into our Nikro vacuum, not your furniture. We agitate with Rotobrush tools, clean the coils and blower, and replace your filter. You get before-and-after photos of your own ducts before we leave. The whole job on an average Middleburg ranch takes roughly 4 to 7 hours.
A dirty coil shows up as a system that runs constantly but won’t cool, with low airflow at the registers. Dirty ducts show up as visible dust blowing from vents, grit on furniture, and musty smells. In Middleburg’s climate, you often have both. Our camera inspection will show you exactly what’s failing, and we’ll quote the fix for that specific problem. Call (737) 727-2314 and we’ll schedule the inspection.
We schedule jobs by appointment because a real cleaning takes half a day or more, and we won’t rush through your home. Same-day promises in this trade usually mean the technician showed up with a shop-vac and a drill brush. We’ll get you on the schedule as quickly as our calendar allows, and you’ll get a live trackable arrival window so you’re not waiting around all day. Call (737) 727-2314 and we’ll find the soonest slot that works.
One more thing. Our crew pulled up to a brick ranch off Blanding Boulevard near the Black Creek boat ramp where the homeowner’s 20-year-old system was short-cycling and her registers were blowing grit onto the furniture. We ran a camera inspection down the main supply trunk, found the flex run collapsed and a rodent-chewed return near the air handler, then set up negative pressure with HEPA filtration and used agitation tools to do a full source removal. After new flex and a MERV 8 filter at the return, her static pressure dropped and the grit stopped, and we handed her before-and-after photos of her own ducts before we packed up. That’s the job, done the way it should be.
