Clad in a bright blue jumpsuit and blue-billed cap, he seems to have been everywhere—photos show him in front of the Eiffel Tower, under the marquee at the Late Show With David Letterman, and next to an ornamental gate at Beijing Airport, to name a few. He's Bluey, the petite plush toy who serves as Blue Dot Services of Maryland's mascot. And his jet-setting lifestyle is the result of fans and staff transporting him around the globe in search of amusing photo opportunities.

Blue Dot's expert heating and cooling technicians apply the same dedication to HVAC maintenance and repair work that Bluey fans apply to his travels. After an initial consultation and price estimates in homes or offices, staffers schlep parts and equipment from brands such as Bryant, Payne, and Carrier to regulate wonky heaters, install and repair air conditioners, and mend water heaters that can leak, scald, or send rust through faucets. Blue Dot also installs energy-efficient systems and add-ons, such as solar panels, which keep spaces economical, and the company's work with the Comfort Institute regulates indoor air quality by banishing drafts and humidity. The online appointment scheduler helps homeowners connect to staffers 24 hours a day, even while dictating their water pumps' latest tweets.
