Central
Air Conditioning
A
Residential Split System Central Air Conditioning system keeps
your entire home cool in the warmer months, while it helps lower
indoor humidity levels.
The
system includes a compressor, a fan, condenser coil, evaporator
coil, and a refrigerant. It extracts heat from indoor
air and transfers it outside, leaving the cooled indoor
air to be recirculated.
The
efficiency of central air conditioning systems is rated
using SEER ratios.
A
central air conditioning system uses electricity as its
power source, and requires:
An outdoor
section (the condensing unit).
A matching indoor gas or oil furnace with coil, or air handler.

Ductwork
to transfer the cooled air throughout the home.
YORK offers a wide variety of Residential Split System Central
Air Conditioning systems in different sizes and efficiencies.
Electric
Heat Pumps
A
Residential Split System Heat Pump is a year 'round comfort system.
In the summer it draws heat out of your home to keep it cool,
and in the winter it draws heat from outside air into your home
to keep it warm. Many heat pump installations have a booster electrical
resistance heater that automatically supplements heat brought
in from the outside. Outside air always has heat in it -- even
at very low outdoor temperatures.
Like
a central air conditioning system, it includes a compressor,
a fan, outdoor coil, indoor coil, and a refrigerant.
The
efficiency of Heat Pumps is rated using SEER (for cooling
efficiency) and HSPF (for heating efficiency).

Heat Pump uses electricity as its power source, and requires:

A
matching indoor gas (natural or propane) or oil furnace
with coil, or air handler.

Ductwork to transfer the heated or cooled air throughout the home.
YORK
offers a wide variety of Residential Split System Heat Pumps in
different sizes and efficiencies.
A
Residential Furnace keeps your home warm during the cold months,
and can be an integral part of a central air conditioning and/or
indoor air quality system.
The
basic components of a furnace system are:
A
Burner, through which gas (natural or propane)
or oil is delivered and burned.
A Heat Exchanger, where the heat produced from
the burning gas is transferred to the air distribution
system.
Ductwork, to transfer the heated air throughout the home.
A Flue or Vent Pipe, to exhaust byproducts of combustion
(such as water vapor and carbon dioxide) to the outside.

The efficiency
of a furnace is rated using a percent of AFUE.
A
gas furnace uses natural gas, although some models can be converted
to utilize propane. An oil furnace uses heating oil. An electricity
source is required to run the control systems, blower and some
accessories.
YORK
offers a wide variety of Residential Gas and Oil Furnaces in different
sizes and efficiencies.
Single
Packages
A
Residential Single Package System is a year 'round comfort system
in which all equipment is self-contained in one unit and installed
outdoors, typically on a concrete slab or other platform.
In the summer, a single package system provides the comfort
of central air conditioning. During the colder months,
the unit provides heat. Essentially, it is an air conditioner
and heating unit in a single package, hence the name.
Models
are available using:
Electricity
for resistance heating and cooling.
Gas for heating and electricity for cooling.
Heat pump models using electricity.
The efficiency of single packages are rated using SEER
(for cooling efficiency), AFUE% (for gas heating efficiency)
and HSPF (for heat pump efficiency). Ductwork is required
to transfer the heated or cooled air throughout the home.
YORK
offers a variety of Residential Single Package Systems
in different sizes and efficiencies.

Air
Cleaners and Other Accessories
Home
comfort is more than just heating and air conditioning. It also
depends on regulating the flow of heat, eliminating drafts, and
improving the quality of the air you breathe.Electronic
and Media Air Filters Electronic
air cleaners can remove up to 95% of airborne dust, pollen, odors,
tobacco, and cooking particles. Advanced passive media filters
are up to five times better at cleaning than typical furnace filters.
Both are installed in your home's ductwork, typically adjacent
to a furnace or air handler.Effective
filtration systems can help maintain or improve the operating
efficiency of heating and cooling equipment. Operating costs savings
have been projected as high as 15% over the life of the system.
Heat
Recovery Ventilator
A
Heat Recovery Ventilator exchanges stale indoor air for
fresh outdoor air with minimal heat loss. In winter, warmth
from the indoor air being vented out is transferred to
the outside air being drawn in. The system can effectively
control moisture and pollutants.

Zone
Control Systems
Zone
Control Systems eliminate "hot and cold spots" and can
help save energy.
A
Zone Control System splits your house into areas with
common heating and cooling requirements, and puts every
"zone" under the control of its own thermostat.
Each zone is effectively heated or cooled independently
of the others. A system of electronically controlled dampers
directs heated or cooled air to where it is needed --
reducing energy bills as much as 30%.
