Fujitsu
Wins Rural Pennsylvania Home Tug-of-War
When they built their two-story, 3,000 s.f.
home in rural Lancaster County, PA seven years ago, the Thomas’ were sure
that the bonus room above the three-bay garage would be used for storage.
But eventually their interest in using most of the space as a media room
won the tug-of-war.
When Dave Yates, president of York,
PA-based F. W. Behler, Inc. was called in to offer an opinion, he
recommended a ductless split system heat pump by Fujitsu. The installation
was completed by two professionals in less than three hours. Today, the
Thomas’ enjoy year-round comfort with 20 SEER, and 10 HSPF operational
efficiency – almost off the charts for standard (non-geothermal) HVAC
systems available today.
While inspecting the home, Yates learned
that it had two central HVAC systems; one for the first floor and a
separate one for the upper floor. He determined that the new media room –
because of its size, the challenge of heating and cooling the space above
a non-conditioned garage, and with so much exposure to western wind and
sun – was a larger load than the existing equipment could handle without
major changes.
“This
job was ideally suited to use a ductless system which would condition the
interior space right where, and when, the family wanted it,” said Yates.
“This technique saves energy by containing the heat or air conditioning.”
Mini splits are ideally suited for home
improvement, whether an existing central air system is installed, or not.
This approach can be less expensive and less disruptive than retrofitting
an existing HVAC system.
Sleek, new mini-splits with variable speed
“inverter” technology have been in use for several decades in Eastern and
European countries and now they’re catching on in the USA as energy costs
continue their upward spiral. The notion that every room in a home must
be conditioned to the same temperature – all the time – is losing its
appeal among Americans.
Punch the gas? Or feather it?
Old school, on-off technology for any type
of HVAC equipment is rapidly losing its appeal here in the land of
plenty. With this old-style technology, it’s like driving your car with
the gas pedal glued to the floor and controlling it purely by turning the
ignition key on or off!
The new approach – and one
that made sense to the Thomas family – is the use of equipment that
continuously modulates its energy production to match heat loss and gain.
That’s like feathering the gas pedal in your automobile to meet the speed
you need. Toss in new “automatic modulation” and you get ultra-high
efficiency operation, complete with the chauffer to drive the car.
All the homeowner needs to do is to set the
desired temperature or humidity level and leave the rest up to the
equipment. The “brain” behind it all is a computerized logic module in
the outdoor unit that communicates with system sensors and the indoor
unit.
Ultimately, the homeowner is rewarded with
a whisper-quiet comfort system that gingerly sips electrical current, is
better for the environment, and goes in fast. Professionals like it for
the same reason.
