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 Sellersville’s Preferred HVAC Cleaning Company
We work in Sellersville homes every week, and the systems here are not like what you find in newer subdivisions. Much of the housing stock was built before central air was standard, which means a lot of retrofits, added coils, and return trunks that were sized for a furnace that is no longer there. That matters because a generic duct cleaning that counts registers and vacuums the supply side misses the actual problem. Our HVAC Cleaning team is trained to inspect the full system first, identify where the debris is actually collecting, and clean it under negative pressure so it does not blow back into your living room.
Cardinal Air Duct Cleaning is part of the Relay Home Co. family, founded 2005. Every booking is held to The Relay Visibility Guarantee: a live trackable arrival time, before-and-after photos of your own ducts, and a digital invoice you can pay from your phone. Our technicians are background-checked, uniformed, and you know their name before they knock. Omar Haddad leads the team, and the standard is simple: a written price before work starts, a written guarantee on the work, and a full year to call us back if something was not done right. That is the 365-Day Done Right Promise, and it applies to every Sellersville job without exception.
AC Duct Cleaning in Sellersville
AC Duct Cleaning in Sellersville means opening the supply and return side of a duct system that is often a patchwork: original trunks from a 1960s furnace, flex runs added for a second-floor addition, and a coil that was spliced in when central air finally arrived. The job here is not just brushing out the accessible registers. It involves a camera inspection of the trunks and runs, mechanical agitation to break debris loose, and HEPA-filtered negative-pressure extraction at the unit so the loosened material is captured, not recirculated. Homeowners should consider it when supply registers are blowing visible dust, when the blower is running noisier than it used to, or after any major renovation that left drywall dust inside the system. A standard AC duct cleaning in Sellersville runs $400 – $700 depending on system size and condition.
Evaporator Coil and Air Handler Cleaning
On older Sellersville systems, the evaporator coil sits above a furnace that may have spent decades burning oil. The coil picks up a sticky, sooty film that reduces airflow and pushes the system to run longer. We pull the coil access panel, photograph what is there, and clean it with a process that does not bend the fins or flood the cabinet.
Blower Motor and Return Side Cleaning
The blower wheel is where the real accumulated debris lives in many Sellersville homes. A dirty blower wheel moves less air, forces the motor to work harder, and recirculates whatever has settled on it. We remove the blower assembly, clean the wheel and housing, and vacuum the return trunk so the air coming back into the system is not pulling through a layer of old dust and pet hair.
Furnace Cleaning in Sellersville
Furnace Cleaning in Sellersville focuses on the heat exchanger, blower assembly, and the return side of the duct system. Oil-fired furnaces, which are common in the older borough housing stock around Main Street and the streets running toward Lake Lenape, produce a fine soot that works its way past the filter and settles through the cabinet and into the returns. A furnace cleaning for a standard Sellersville home runs $450 – $850 when it includes the full duct system and air handler. If the furnace is being serviced as a standalone unit without the full duct work, expect $200 – $400. The difference depends on what has been neglected and how much access the blower and coil allow.
Heat Exchanger and Cabinet Cleaning
We brush and vacuum the accessible surfaces inside the furnace cabinet, including the blower compartment and the area around the heat exchanger. This is not a substitute for a full safety inspection of the exchanger, but removing the layer of soot and dust lets the furnace move air the way it should and reduces the musty smell that older systems push through the house on cold mornings.
Condenser and Outdoor Unit Cleaning
For homes with central air retrofits, the condenser outside is usually tucked against a wall, under a deck, or behind a bush. Sellersville lots are tight, and the units collect leaves, cottonwood, and grass clippings quickly. We clean the coil fins, clear the surrounding area, and check the disconnect so the outdoor unit has room to shed heat in July.
Trusted Brands We Service in Sellersville
We service and clean systems built around equipment from Carrier, Trane, Lennox, Rheem, Goodman, York, and most other major manufacturers. Because Sellersville homes run a mix of oil furnaces and newer air-source heat pumps, our trucks carry a broad set of filters, belts, and coil cleaning supplies so most jobs finish in one trip. Our equipment is professional-grade: Rotobrush rotary brush systems for duct agitation, Nikro HEPA vacuums for extraction, and Abatement Technologies containment units when a job kicks up more than normal household dust. If your blower needs a new capacitor or the condensate line is clogged, we typically have the part on hand.
Common HVAC Cleaning Problems We See in Sellersville Homes
- Mismatched return trunks. Many older Sellersville homes had central air added to a furnace system that was never sized for it, so the return side is undersized and pulls hard. That negative pressure drags dust from wall cavities and basement seams into the air stream, and cleaning only the supply registers does nothing for it.
- Oil furnace soot buildup. Homes that still run oil heat produce a fine, greasy soot that coats blower wheels and return plenums. It is sticky enough that a standard vacuum will not lift it, and it causes that oily dust smell when the heat first kicks on.
- Renovation dust in retrofitted runs. Sellersville homeowners do a lot of finished basements and attic conversions. The drywall dust from those projects settles deep into flex runs and trunk lines, and it stays there until someone agitates it loose with the right equipment.
- Disconnected or collapsed flex in hard-to-reach spaces. Our camera inspections regularly find a run that has pulled off a takeoff collar behind a finished wall or above a drop ceiling. The system runs, but it is heating or cooling a crawlspace instead of the room it is supposed to serve.

FAQs About HVAC Cleaning in Sellersville
Most Sellersville homes need a full HVAC cleaning every 3 to 5 years, though homes with oil heat, multiple pets, or recent renovation work may need it sooner. You will know it is time when registers blow visible dust, the blower sounds strained, or there is a musty smell when the system starts. Call (737) 727-2314 and we can help you decide if your system is actually due or if it can wait.
We price the whole system as one flat number, never per vent. Per-vent pricing is how homeowners get surprised with a bigger invoice once the technician sees the inside of the ductwork. Your written quote is the price you pay, no matter how many runs or registers the system has.
Yes. Every job includes before-and-after photos of your own ducts, including the return trunks, supply runs, blower, and coil. You will see the difference on your own system, not in a generic brochure. That photo documentation is part of The Relay Standard and it is delivered before you pay.
We answer the phone live at any hour, but HVAC cleaning is a scheduled appointment, not a same-day emergency call. We will give you the earliest honest availability when you call (737) 727-2314, and a live trackable arrival window so you know exactly when we are coming. No four-hour wait windows.
Older homes in Sellersville often have retrofitted ductwork, oil-furnace soot, or a finished basement that blocks access to the main trunk. The extra cost is for the camera inspection, longer agitation time, and careful containment those systems require. It is not an upcharge, it is the actual work the home needs.
Call Cardinal Air Duct Cleaning in Sellersville
We were called to a home near the Main Street area of Sellersville Borough where a finished-basement install had left a return trunk undersized for the newer blower motor. The blower was moving air faster than the returns could supply, and the system had pulled a layer of dust across every surface in the house. Our tech ran a camera inspection, broke the debris loose from the trunk with agitation tools, and pulled it out under negative pressure with HEPA filtration at the unit. We photographed the supply and return ducts before and after, and the homeowner could see the difference on their own runs. That is the standard we bring to every Sellersville job. Call (737) 727-2314 for a free estimate, a written price before we start, and a full year of coverage under the 365-Day Done Right Promise.
