Carpets, like dogs, often hide under the dining-room table and let out audible whimpers when threatened with bath time. Make your carpets howl like the beasts they are with today's Groupon: for $139, you get up to 2,000 square feet of in-home air-duct cleaning, along with up to 400 square feet of carpet cleaning for up to two bedrooms from Fresh Environment (a $295 value). Today's Groupon may be used for homes throughout the Bay area, from Novato to San Jose.

Fresh Environment's thorough cleaners air out dusty domiciles with interior-cleansing duct and room treatments. Experienced technicians start each scheduled cleaning with a full air-duct system inspection, removing vent covers to take an up-close eyeball of the house's circulation systems. After the initial assessment, ducts undergo a thorough brushing and vacuuming with Fresh Environment's air-purifying HEPA vacuum, freeing them from dust, pollen, and families of lost moles. Cleaners then move from the ceiling to the floor, revitalizing up to 400 square feet of bedroom carpet. Save shag with an eco-friendly steam-cleaning, bringing tired bedchambers back to life in advance of spring-cleaning deadlines or lullaby concerts performed by live string quartets.
