DuoVac central vacuum systems look like a smart buy at first glance. Quiet motors, brushed aluminum canisters, and a 25-year warranty that reads like a forever promise. The problem? Nobody mentions that Nuera Air, the Montreal company that built DuoVac, filed for bankruptcy in April 2024. That long warranty now lives with a different company entirely.
By the time you finish reading, you’ll know which DuoVac models you can still buy, whose name backs the warranty today, and whether one of these central vacuum brands worth knowing belongs in your walls.
Keynote: DuoVac Central Vacuum Systems
DuoVac central vacuum systems are Canadian-engineered ducted vacuums combining hybrid filtration with thru-flow or bypass motors and up to 810 air watts of sealed suction for homes from 800 to 10,000 square feet. The brand changed hands in 2024 when Les Industries Trovac Ltd. acquired it out of Nuera Air’s bankruptcy. Buying DuoVac today means committing to a system whose support network is still rebuilding, so parts availability and warranty service matter as much as the motor rating on the spec sheet.
Why DuoVac Looks Smart Until You Dig Deeper
Are DuoVac central vacuum systems still worth buying today?
DuoVac still makes sense for the right buyer, but the 2024 bankruptcy changed the equation in ways no dealer page explains. Nuera Air, the Montreal-based manufacturer behind the DuoVac lineup, ceased manufacturing operations with its bankruptcy first reported on April 2, 2024. That shutdown pulled DuoVac, Husky, SoluVac, Smart, and InterVac off active production simultaneously.
Note that Beam central vacuum, owned by Electrolux Group since its acquisition of the brand’s global central vacuum assets, operated as a separate entity and continued without disruption. The Nuera collapse was specific to its own brand portfolio. The evaluation in this guide draws from manufacturer documentation published under Trovac’s ownership, verified owner accounts on RedFlagDeals and VacuumLand, and spec comparisons cross-referenced against the Trovac-era owner’s manual.
Who actually owns DuoVac now and why it matters
Les Industries Trovac Ltd., the Quebec-based manufacturer known as Trovac Industries, acquired the DuoVac brand portfolio by July 2024. Trovac has its own central vacuum manufacturing background, so the acquisition brought genuine production capability and parts inventory under one roof.
What no retailer mentions: units manufactured before the acquisition carry legacy warranty terms that may not match what Trovac now honors. Per DuoVac’s current warranty terms under Trovac, units manufactured as of September 2024 fall under the current owner’s manual terms. Pre-acquisition units from a dealer clearing old stock need a written answer about who services them before you commit.
A 25-year motor warranty only works if the servicing company still operates 15 years from now.
The reputation you are really buying into
DuoVac earned its name on three things: low noise output, hybrid filtration that runs with or without a bag, and brushed aluminum canisters built to survive a garage install. Installers who put in DuoVac units through the 2010s describe motors that ran long and quiet in homes from Montreal to Calgary. That heritage is real.
Heritage doesn’t answer a warranty claim in 2027, though. Weigh the legacy against the support gap before you spend north of $1,500 on a built-in system.
The DuoVac Lineup You Can Still Find
Simplici T for apartments, condos, and tight spaces
The Simplici T covers up to 3,500 square feet at 642 air watts and 134 inches of water lift, and it fits a mechanical closet that would reject a full-size canister. For the condo owner who hauls a portable upstairs every single time the floors need a pass, that’s a real change in daily life.
One limitation: the Simplici T runs bag-only. The hybrid bagless option doesn’t appear at this tier. For allergy-sensitive households, sealed bag disposal is actually the cleaner choice. Buyers who want the flexibility to run without bags should step up to the Air 10.
Air 10, the workhorse everyone compares against
The Air 10 generates the most comparison traffic of any DuoVac model, and the spec confusion starts here. Depending on which retailer lists it, the same Air 10 shows 651 air watts on some pages and 694 on others.
| Spec | Air 10 |
|---|---|
| Air Watts | 651 to 694 (varies by source) |
| Motor Type | Two-stage thru-flow |
| Water Lift | Up to 110 inches |
| Filtration | Washable filter, hybrid capable |
| Coverage | Up to approx. 3,000 sq ft |
Marketing figures quote the bare motor at peak RPM with no flow restriction. Finished-system measurements capture performance at the hose under realistic load. Use the lower figure for any pipe-run calculation. The two-stage thru-flow motor keeps noise down but runs exhaust air through the motor body for cooling, exposing windings to filtered air over years of use. For homes under 3,000 square feet with short, straight pipe runs, the Air 10 performs consistently. Stretch it across a 65-foot run on a two-story layout with four elbows and you’ll feel it at the far bedroom inlet.
Air 50 and Star for big square footage homes
The Air 50 steps up to 702 air watts with a 9.6-gallon canister, and the Star anchors the top tier at 756 air watts with a two-stage motor. For a family running a large home with kids, dogs, and hardwood throughout, these are the two worth comparing seriously. The 9.6-gallon canister on the Air 50 means far fewer trips to empty, and on a pet-heavy home the capacity difference pays for itself in convenience inside the first year.
Buyers comparing options across the Canadian market should review central vacuum systems in Canada before landing on any single brand, especially while Trovac’s dealer network continues to rebuild.
Which models quietly disappeared after the shutdown
Older DuoVac lines including Typhoon, Select, and several earlier-generation units still appear on stale retailer listings and Amazon storefronts as of 2026. These are not current production models. No confirmed parts availability exists for discontinued lines. Confirm in writing that the model you’re buying is in active production before you send payment.
Air Watts, The Number Dealers Love To Inflate
Why one model shows two different air watt numbers
You’re not misreading the page. The Air 10 appears at both 651 and 694 air watts across different retailers for the same unit. Some listings measure bare motor output at peak RPM. Others measure sealed system performance at the hose under realistic load. Ask every seller directly: is this the bare motor spec or the finished, installed system measurement? The answer tells you which retailer did their homework.
Water lift versus air watts, explained like you are ten
Water lift measures pulling force in a sealed system, expressed as inches of water column the unit can hold. Think of it as raw grip for lifting heavy debris up vertical runs and through tight fittings. Air watts combine that pull with airflow volume into a single number using the formula: watts equals CFM multiplied by water lift divided by 8.5.
Use water lift as your primary spec for homes with long vertical runs, staircases, and embedded pet hair. Airflow matters more for fine dust on smooth hard floors. And for allergy households, remember that per the EPA’s definition of a HEPA filter, true HEPA capture at 0.3 microns depends on certified filter media, not airflow volume alone.
How far your inlets sit before suction fades
Every 10-foot pipe run extension costs measurable suction at the hose end. Every 90-degree elbow added beyond the manufacturer’s maximum compounds that loss. A DuoVac Air 10 rated for approximately 3,000 square feet delivers noticeably weaker performance at a far bedroom inlet on a 65-foot run with four standard elbows versus a 30-foot run using a single sweep elbow off the main trunk.
Plan inlet distance against the motor rating, not the brochure square footage. Use sweep elbows at every direction change on any branch exceeding 30 feet.
Filtration, HEPA Claims, And The Bag Question
Does DuoVac truly capture 99.97% at 0.3 microns?
DuoVac’s certified HEPA filtration models claim 99.97% particle capture at 0.3 microns, matching the U.S. DOE HEPA threshold. The spec only holds on units carrying actual HEPA certification, not models marketed as “HEPA style” or “HEPA grade.” Confirm the specific model you’re buying carries documented certification before trusting any filtration claim on the retailer page.
Hybrid filtration: should you run a bag or not?
DuoVac’s hybrid system runs with or without a bag, and that flexibility is what justifies the premium over a standard bagless unit.
| Mode | Allergen control | Disposal mess | Ongoing cost |
|---|---|---|---|
| Bagged with true HEPA bag | Highest | Minimal, sealed | $15 to $30 per bag |
| Bagless with washable filter | Good | Moderate dust exposure | Filter wash only |
| Hybrid (bag plus filter) | Highest | Minimal, sealed | Bag cost plus filter wash |
Use a true HEPA bag setup for anyone in the household with asthma, allergies, or pet dander sensitivity. The bag captures fine particles at the canister before they reach the filter, and disposal stays fully sealed.
What SILPURE antibacterial treatment actually does
SILPURE is a silver-ion treatment applied to DuoVac’s washable permanent filters. Silver ions limit the growth of odor-causing bacteria on the filter surface between wash cycles. Pull a neglected filter from a unit that’s run two years without washing and you’ll understand why this matters before you read the spec.
SILPURE manages odor. It does not improve particle capture or extend filter life beyond the manufacturer’s wash interval. Wash the filter on schedule regardless of whether it smells fine.
What Forum Owners Wish They Knew First
The “no dealer near me” online ordering trap
One buyer on RedFlagDeals put it plainly: the 25-year warranty looked solid, but the nearest authorized service depot was four provinces away. Ordering online to save $200 on a $1,400 system makes sense until the unit needs service and you’re boxing it for a cross-country shipment.
Price return freight and self-installation labor before the warranty length closes the sale. A local dealer who installs and services the unit carries more real value than a discounted price from a retailer who stocks the box but not the knowledge. The Soluvac central vacuum models reviewed on this site show what happens when another Nuera Air brand faces the same post-acquisition dealer-network uncertainty.
Hoses and handles wear long before the motor
A consistent pattern across verified owner reviews: the motor runs fine for a decade, but the hose gets replaced once, the handle twice, and the power brush head once before the unit sees its sixth year. Budget $150 to $300 for hose and handle replacement across the life of the system. Don’t let the motor warranty dominate the decision while ignoring the real annual cost of consumable parts.
Why one enthusiast dropped DuoVac from his top picks
A longtime VacuumLand member kept DuoVac in his top five central vacuum recommendations for years. After Nuera Air folded, he moved DrainVac into that slot and hasn’t moved it back. The reason wasn’t motor quality or filtration design. He couldn’t get a clear answer about who stocked parts six months after the Trovac acquisition closed. Enthusiast trust rebuilds slowly, and DuoVac under Trovac will need to demonstrate consistent parts response before the community consensus shifts.
Installation Mistakes That Quietly Kill Suction
Inlet placement for a real two story home
The frustration of a hose that won’t reach the back corner of the master bedroom isn’t a hose problem. It’s a planning problem from before drywall closed. For a two-story home around 2,400 square feet, plan at least one inlet per 600 to 700 square feet per floor, positioned so a 30-foot hose covers every corner of that zone. On a standard two-story colonial with a central staircase, that means two inlets per floor at opposite ends of the main corridor. One badly placed inlet on the second floor turns a premium system into a daily fight with hose reach.
Per a manufacturer central vacuum installation guide, the power unit requires a dedicated 120 VAC 15 or 20-amp branch circuit wired with at least 14 AWG on its own breaker, separate from kitchen or laundry circuits. Skipping the dedicated circuit is the most common installation error that causes nuisance tripping under full motor load.
Pipe runs, elbows, and the noise you can hide
Mount the power unit in the garage, vent the exhaust outside, and the only sound you hear in the house is air moving through the hose. That’s the experience owners describe consistently once the system is running. Not the motor. Just air.
Keep Schedule 40 PVC runs as straight as possible and use sweep elbows at every direction change. A standard 90-degree fitting in a long run loses as much suction as an extra 10 feet of pipe. On a 70-foot run from the garage to the second floor, that difference is real at the hose end.
Is A DuoVac Worth It For You?
The warranty math when the maker changed hands
A 25-year warranty is worth exactly what the company behind it is worth. Trovac has genuine manufacturing capability, but the gap between legacy Nuera Air units and current Trovac production is real and unresolved for buyers holding older stock.
| Warranty scenario | Who covers it | Risk level |
|---|---|---|
| Unit built after September 2024 | Trovac Industries | Low |
| Unit built before April 2024, Nuera stock | Unclear, ask in writing | High |
| Discontinued model (Typhoon, Select) | None confirmed | Very high |
HomeAdvisor data puts the average installed cost of a central vacuum at $1,583, with a typical range of $1,094 to $2,194 for most home sizes. Retrofit work through finished walls adds $400 to $1,000 in labor on top of that. At that investment, a warranty gap carries real financial weight. Get the current servicer confirmed in writing before you commit.
Match the system to your floors and square footage
A pet owner choosing between the 702 air watt Air 50 and the 756 air watt Star shouldn’t decide on a 54 air watt gap alone. A strong motorized power brush head that drives bristles into low-pile carpet at the right RPM lifts embedded pet hair that a weaker head leaves behind, even with higher raw suction. Size the power unit to your largest single floor and add 20% margin for long pipe runs. The motor supports the brush. The brush does the actual work.
When a Miele or DrainVac beats a DuoVac
A central vacuum pays off in a home you plan to own for at least five to seven years. The pipe runs in the walls and the inlet valves at every junction stay behind when you move. A premium portable Miele holds its value and follows you to the next address.
DrainVac, the Quebec-based alternative that gained ground as DuoVac’s dealer network thinned after the Nuera collapse, now covers the mid-size Canadian home segment DuoVac once led. Active parts availability and no recent ownership disruption make it a serious alternative worth pricing side by side.
Conclusion
You arrived thinking a long warranty made DuoVac the safe pick. You leave knowing the manufacturer changed hands in 2024, and support and parts availability now matter as much as air watts. Tonight, email the seller and ask in writing who services the warranty and stocks replacement parts today. Save the reply. When the motor sits hidden in the utility room and you clip in the hose at the inlet three floors up, the daily ease beats any canister you’ve dragged up the stairs. But only if someone still stands behind the system.
Frequently Asked Questions
Is DuoVac still in business and who owns it now?
Yes, DuoVac sells under active ownership. Les Industries Trovac Ltd. acquired the brand in June 2024 after Nuera Air’s April bankruptcy. Units manufactured from September 2024 onward carry warranty terms backed by Trovac per the current owner’s manual.
What is the difference between air watts and water lift on a DuoVac unit?
Water lift measures sealed pulling force. Air watts combine that pull with airflow volume into a single performance number. Use water lift to compare raw suction strength and air watts to compare real cleaning output at the brush head under load.
Which DuoVac model is right for my home size?
The Simplici T handles up to 3,500 square feet, the Air 10 suits homes up to around 3,000 square feet with moderate pipe runs, and the Air 50 and Star handle 4,500 square feet and beyond. Size to your largest single floor, not the whole-home total.
What is the difference between a thru-flow and a bypass motor in DuoVac systems?
A thru-flow motor runs exhaust air through the motor body for cooling, keeping noise low but exposing windings to filtered air over time. A bypass motor keeps the cooling and suction airstreams fully separate, protecting the motor and typically extending lifespan in high-debris environments.
Are DuoVac parts and bags still available after the Trovac acquisition?
Trovac has continued parts supply for current production models. Discontinued lines like Typhoon and Select carry no confirmed availability as of 2026. Confirm bag and motor supply in writing with your dealer before purchase, specifically for the model you’re buying.
