Cost Guides (Twin Cities)
How much does air duct cleaning cost in the Twin Cities?
The short answer
A proper, NADCA-method air duct cleaning for a typical Twin Cities single-family home generally runs about $300–$700+, depending on the size of the system, the number of supplies and returns, and how much buildup is present. Be skeptical of rock-bottom "whole-house" specials, that price almost always buys a quick "blow-and-go" that relocates dust instead of removing it.
What's the typical range for a real duct cleaning?
For most single-family Twin Cities homes, a thorough, source-removal cleaning runs about $300–$700+. Larger homes, multiple systems, or heavy contamination land higher. We quote a clear, flat price after we understand your system, no per-vent surprises halfway through.
A complete job cleans the whole connected system, not just what you can see:
- Every supply and return, the registers and grilles, and the main trunk lines.
- The air-handler components, the blower, evaporator coil, and drain pan.
- Verification before and after, ideally on camera, so you see the result.
That's the difference the NADCA source-removal method makes, read how it works to see why it takes hours and real equipment.
What drives the price up or down?
The honest variables behind your quote:
- System size and vent count. More supplies and returns, and larger trunk lines, mean more time and labor.
- Number of systems. A home with two furnaces and two coils is essentially two cleanings.
- Level of contamination. Heavy dust, post-remodel construction fines, or pet dander take longer than routine maintenance.
- Accessibility. Hard-to-reach runs and tight mechanical rooms add time.
- Real problems we find. Active mold, moisture, or a pest infestation isn't a standard cleaning, those need the source addressed first, and we'll tell you honestly.
Why the cheapest ad almost always costs more
The classic rock-bottom "whole-house" or "unlimited vents" ad is a marketing hook. What usually happens is one of two things:
- Blow-and-go. A quick blast of air at the registers with no negative-air containment. Without a HEPA-filtered vacuum putting the whole system under negative pressure, the debris just gets stirred up and resettles, your ducts aren't actually clean.
- Bait-and-switch. The cheap price gets them in the door, then the bill climbs with "extra" charges for the things a real cleaning includes from the start.
A fair, flat quote for the genuine NADCA method costs more than a teaser special because it does something the cheap version doesn't: actually remove the contaminants. See the signs your ducts need cleaning so you only pay when there's a real reason.
Getting the most value from a cleaning
A few ways to make the spend count:
- Bundle related work. Having your dryer vent cleaned at the same visit can save a separate trip.
- Pair it with better filtration. Clean ducts plus the right filter keeps the result lasting, see indoor air quality.
- Don't over-clean. Ducts don't need cleaning on a fixed calendar. If an inspection shows yours are fine, we'll say so rather than sell you a service you don't need.

Frequently asked questions
- Why is your price higher than the cheap ads I see?
- Because it buys a different service. A real, NADCA-method cleaning puts the whole system under negative pressure with a HEPA-filtered vacuum and cleans the blower and coil too, work that takes hours and proper equipment. The very cheap ads are typically a blow-and-go that relocates dust rather than removing it.
- How often do I actually need duct cleaning?
- There's no fixed schedule. NADCA recommends cleaning when there's a demonstrated need, visible dust, a recent remodel, pests, or a musty smell. Homes with pets, allergies, or smokers may need it sooner. We inspect first so you only pay when it's warranted.
- Does the price include the furnace blower and coil?
- In a complete job, yes, the blower, evaporator coil, and drain pan are part of the system and a proper cleaning includes them. Be wary of any quote that treats those as add-ons, since skipping them leaves the dirtiest parts untouched.
- Can you clean my dryer vent at the same time?
- Yes, and combining the visits is often more convenient and cost-effective. Dryer vent cleaning is a separate, fire-safety service handled by our CSIA C-DET certified technicians.
