Who We Are:
LB Appliance Design
LB Appliance Design (operating online via lbdsgn.com) is an independent specialty technical depot offering premium vacuum cleaner repair, calibration, and product restoration services. Founded in Ontario, our laboratory is staffed with appliance engineers dedicated to keeping premium floorcare systems out of local landfills.
We pride ourselves on an open-door policy. Unlike generic mechanics, we use calibrated custom testing gear (the LB-DSGN Testing Protocol) to analyze static water lift, cubic-feet-per-minute airflow, and filter efficiency. We offer transparent estimates upfront and never initiate labor without your explicit, written verification.
Safety Verified
Every vacuum undergoes strict electrical insulation resistance testing (HIPOT test) post-repair to ensure safety.
Eco-Friendly
We rebuild electric motors, replacing worn carbon brushes and bearings to avoid total device discard.
Express Turnaround
With our extensive domestic parts inventory, most common issues are fully resolved within 48 hours of intake.
Precision Calibrated
We verify suction output using digital anemometers to match factory specifications of leading brands.
The LBDSGN Standard
We developed the LBDSGN Testing Protocol (Light, Blue, and Diagnostic System Grid Network) to map electric load, thermal build-up, and localized brush friction.
Grid System Mapping
We analyze electrical draw across five discrete levels of cell load to pinpoint failing dynamic armatures or structural battery battery cell decay.
Sealed Suction Check
By pulling negative barometric pressures inside our custom testing test chamber, we evaluate seal integrity and identify microscopic cracks in the housing.
Acoustic Tuning
Every replaced fan impeller is digitally balanced to minimize acoustic resonance and vibratory wear, boosting motor lifespan by over 200%.

"My Dyson V10 was cutting out every 5 seconds. Took it to the LBDSGN laboratory on Queen St W. They ran a diagnostic check, rebuilt the dynamic battery trigger, and had it ready in 24 hours. Phenomenal transparency and standard rates!"
"I sent in my Miele canister vacuum via post from Montreal. The team sent photos of the carbon motor brushes and gave me an upfront quote of $89 CAD. Absolutely brilliant service model, zero hidden fees."
"They mapped the electrical failure in my Roomba instantly using their custom testing diagnostic tools. I bought the upgraded replacement filters from their online store too. Highly recommended white-glove technical specialists!"
