Mitsubishi Electric Serves Up an Ideal Cooling Solution
Shirley and Brice Phillips came to
Ocean City with their two young
sons in 1956. They purchased a small
shack on the beach at 20th Street to
serve as a carry-out shop as well as a
store to sell crabs and crabmeat from
the family’s seafood packing plant on
Hooper’s Island on the Chesapeake
Bay. The concept was an immediate
success. By 1967, Phillips Crab House
had expanded to four kitchens and
nine dining rooms. A second Ocean
City location was added in 1973 and
a third location opened four years
later. Phillips Harborplace Baltimore
began serving seafood in 1980, Phillips
Flagship opened on the waterfront in
Washington, D.C. in 1985 and Phillips
Annapolis Harbor opened for business

locations from Ocean City to the
nation’s capital, serving approximately

The Phillips family purchased the
old Harbor House Restaurant with
a commanding view of the historic
Annapolis wharf. The best view of the
harbor was from a large covered terrace
that was closed during the winter. The
first thing the Phillips did was call
in Andy Cascio, the original Harbor
House architect. They wanted him
to devise a plan to enclose the terrace

Due to the harbor location, historical
Annapolis restrictions, a low sloped
terrace roof plan and the aesthetic
requirements of the architect, Frosty
was not able to use a conventional
ducted system exposed on the roof or
in the open ceiling space of the new

this area was to draw on the talents of

Electric units fit nicely where a
conventional system wouldn’t.
“Piping and wiring was much easier to
route through the existing building than
ductwork would have been. Overall
installation costs were about a third of the
cost of a conventional system. Due to the
ease of installation, we were able to meet
the customer’s deadline with time to spare.
Phillips was very pleased with the entire
operation. The split-ductless units are
robust, quiet, reliable and easy to install.
Their heat pumps and INVERTER
technology work extremely well in this
mid-Atlantic region,” Lederer said.

Heat Pump Systems. Overall installation costs were about a third of the cost of a conventional HVAC system.
