Most Murphy homeowners pay between $350 and $700 for a full air duct cleaning, with the average landing around $475 for a 2,000-2,800 sq ft house with 12 to 18 vents. Anything under $200 is usually one truck-mounted vacuum run with no agitation, and anything over $1,200 almost always includes duct sealing, sanitizing, or a second system. That's the short answer. The rest of this post breaks down what moves that number up or down in Murphy specifically - vent counts, system age, attic runs, and the add-ons that are worth paying for versus the ones that aren't.
How much does air duct cleaning cost in Murphy TX?
Air duct cleaning cost in Murphy TX is a function of three things: how many vents you have, how accessible the duct runs are, and how much debris has built up. Typical 2026 pricing in this area runs $350-$700 for a standard single-system home, $700-$1,100 for two-story homes with dual HVAC systems, and $1,100-$1,800 for larger properties with multiple zones, long attic trunk lines, or heavy contamination.
Here's what that looks like across the most common Murphy home profiles:
- 1,500-2,000 sq ft, single system, 8-12 vents: $325-$475
- 2,000-2,800 sq ft, single system, 12-18 vents: $425-$675
- 2,800-3,800 sq ft, dual system, 18-26 vents: $700-$1,050
- 4,000+ sq ft or multi-zone, 26+ vents: $1,100-$1,800
Those ranges assume standard flex duct and accessible attic or crawlspace runs, which describes most of the housing stock in Murphy. Homes with rigid metal ductwork, multiple returns, or ducts buried under blown-in insulation sit at the top of each band. If you want a firm number before anyone shows up, we'll give you one over the phone once you tell us your square footage, system count, and vent count - that's usually enough for us to land within $50.
What actually drives your duct cleaning quote
Four variables move the price more than anything else, and every legitimate duct cleaning quote Murphy homeowners receive will be built from the same four.
1. Number of vents and returns
Vents are the unit of work. Each supply register and each return grille has to be pulled, cleaned, and reseated, and the trunk line behind it has to be brushed and vacuumed. A 10-vent home takes roughly two hours; a 20-vent home takes four. That labor difference is the single biggest line item on your invoice.
2. System count
Two HVAC systems means two air handlers, two blower compartments, two sets of trunk lines, and roughly double the labor. If your upstairs and downstairs units run on separate thermostats, you have two systems and you should expect a two-system price.
3. Duct accessibility
Ducts running through a conditioned attic with a walkway are quick to reach. Ducts buried under 14 inches of blown-in insulation, or routed through a tight second-floor chase, add time. We see this a lot in the older sections of Air duct Cleaning in Downtown Murphy, where additions and re-routes have left some runs with only a few inches of clearance.
4. Contamination level
A home cleaned three years ago is a maintenance job. A home that's never been cleaned, has had a remodel, or has had water intrusion is a remediation job. Heavy dust loading, mold, or rodent debris adds a second pass and often a sanitizing step.
Air duct cleaning price per vent in Murphy TX
Air duct cleaning price per vent Murphy TX homeowners see quoted ranges from $25 to $55 per vent in 2026, with the sweet spot around $35-$45 for standard residential work. That per-vent number is a useful sanity check, but it's not the whole story - a per-vent price that looks cheap often excludes the air handler, the return plenum, or the main trunk line, which are the parts that hold the most debris.
Use the per-vent figure to compare quotes, not to pick the winner. If one company quotes $22 per vent and another quotes $45, ask both what's included. The $22 quote is almost always a surface vacuum of the registers only. The $45 quote usually includes negative-air machine setup, rotary brush agitation of every trunk and branch, air handler cleaning, and a before/after photo set.
For a typical 14-vent Murphy home, that works out to roughly $490 at $35 per vent or $630 at $45 per vent - right in line with the flat-rate ranges above.
Does air duct cleaning cost depend on house size in Murphy?
House size matters, but vent count matters more. Two 2,800 sq ft homes on the same street can differ by $300 if one has 14 vents and the other has 22. Square footage is a proxy; vent count is the actual driver.
That said, size does correlate with a few real cost factors in Murphy:
- Attic trunk length. Larger homes have longer trunk runs, which take longer to brush and vacuum.
- Second systems. Homes above roughly 3,000 sq ft in this area almost always have two HVAC systems.
- Zoning. Multi-zone homes have dampers and additional branch lines that need individual attention.
When you request an air duct cleaning estimate Murphy Texas homeowners can actually compare, give the company your vent count, not just your square footage. Count every supply register and every return grille. That one number will tighten your quote more than anything else you can tell them.
Add-on services and what they cost
Base duct cleaning covers the mechanical removal of debris. Everything else is an add-on, and some are worth it while others are not.
Worth considering
- Air duct sanitizing services Murphy TX: $75-$200. A fogged EPA-registered sanitizer applied after cleaning. Worth it after mold, rodent, or water damage. Skip it on a routine maintenance clean.
- Dryer vent cleaning Murphy TX: $100-$175 as a standalone, often $75 when bundled. This is a fire-safety service, not a comfort service, and it's the one add-on we push hardest on homes older than 10 years.
- Air duct inspection Murphy TX: $75-$150, often free with a cleaning. A camera inspection of the trunk line tells you whether you actually need remediation or just a standard clean.
- Coil and blower cleaning: $150-$350. If your air handler is caked, cleaning the ducts without cleaning the coil just re-contaminates them.
Usually not worth it
- UV lights sold as a duct cleaning add-on ($400+). They have a place, but not as an upsell during a cleaning.
- "Duct sealing" sprayed from inside without a pressure test. Real sealing uses aeroseal or mastic and is verified.
- Enzyme treatments on ducts with no organic contamination. You're paying for a smell, not a result.
What to watch out for in Murphy duct cleaning quotes
The duct cleaning industry has a well-earned reputation problem, and most of it comes from three specific tactics. Knowing them saves you money.
- The $99 door-knock special. A low headline price that becomes $800 once the technician is in your attic with a flashlight and a story about mold. If the price isn't firm before the truck arrives, it isn't a price.
- No air handler access. If the quote doesn't include opening and cleaning the air handler cabinet, blower, and coil compartment, they're cleaning half the system. Debris in the air handler re-enters the ducts the moment you turn the system on.
- No before/after documentation. Any legitimate crew photographs the inside of the trunk line before and after. If they won't show you, you have no way to know the work happened.
One more: be wary of anyone who tells you ducts need cleaning every year. For most Murphy homes, every three to five years is right. Homes with pets, recent construction, or allergy sufferers in the house are the exception - those benefit from more frequent service, and we'll tell you honestly when you don't need us yet.
When to call a professional
You don't need a duct cleaning on a schedule. You need one when the system tells you it needs one. The signals we look for:
- Visible dust puffing out of registers when the system kicks on
- A musty or stale smell that shows up only when the AC or heat runs
- Allergy symptoms that get worse indoors and better when you leave
- Visible mold or moisture staining around a register or in the air handler
- Rodent droppings, nesting material, or dead insects in the duct runs
- A recent remodel, or a new build where drywall dust went everywhere
If two or more of those apply, it's time. Our team handles residential Airduct cleaning Murphy TX for homes of every size in this area, and we'll tell you on the phone whether what you're describing sounds like a standard clean or something more.
Frequently Asked Questions
How much should air duct cleaning cost in Murphy TX?
For a typical Murphy home with 12-18 vents and one HVAC system, expect $425-$675 in 2026. Two-system homes run $700-$1,050. Anything quoted under $200 is usually a register-only vacuum with no trunk line or air handler work, which is why it's cheap.
What is the average air duct cleaning price in Murphy Texas?
The average we see across Murphy is about $475 for a single-system home in the 2,000-2,800 sq ft range. That includes all supply and return vents, the trunk and branch lines, and the air handler. Add-ons like sanitizing or dryer vent cleaning push the total to $600-$750.
Does air duct cleaning cost depend on house size in Murphy?
Yes, but vent count is the bigger factor. Two homes of identical square footage can differ by $300 based on how many registers and returns they have. Give any company your vent count when you ask for a quote and the estimate will be far more accurate.
How long does a duct cleaning take in Murphy?
A 10-vent single-system home takes about two hours. A 20-vent two-system home takes four to five hours. If a company claims they'll clean a 3,000 sq ft home in 45 minutes, they're not cleaning the trunk lines or the air handler.
Is duct cleaning worth the cost in Murphy?
It's worth it when you have a reason - visible dust, musty odors, allergies, recent construction, or a system that's never been cleaned. On a home cleaned within the last three years with no symptoms, the money is better spent on filter changes and a coil cleaning.
