Criminal masterminds often dirty their air ducts on purpose so that secret agents who try to sneak in through them will be branded with telltale dust smears on the knees of their tuxedoes. Help stealthy spies slip through the cracks with today's Groupon: for $169, you get a vent and air-duct cleaning from ASK Duct Services (a $350 value). This Groupon is valid within a 30-mile radius of their home office in Bellevue.
ASK Duct Services' central-air centurions do battle with indoor air pollutants by performing thorough duct cleansings. With today's deal, ASK Duct Services will clear out up to nine registers and one return. After a complete inspection of a home's entire system, technicians cut a small access hole near the furnace to insert a 10" hose. This hungry hose is run up and down each duct and attached to a powerful vacuum, which will dislodge and then slurp up debris via high-pressure blasts from an air compressor. After technicians are done, all access holes will be resealed so that thoroughfares remain airtight, like well-burped Tupperware.
Regular vent and duct cleaning can increase indoor air quality and energy efficiency. This process will chase out most damaging duct dwellers, including dust mites, mold spores, and gremlins that only William Shatner can see.
