The lighter side...
A customer was continually bothering the
waiter in a restaurant; first, he'd asked that the
air conditioning be turned up because he was
too hot, then he asked it be turned down cause
he was too cold, and so on for about half an
hour. Surprisingly, the waiter was very patient,
walking back and forth and never once getting
angry. So finally, a second customer asked why
didn't they just throw out the pest. "Oh, I don't
care." said the waiter with a smile. "We don't
even have an air conditioner."

13 SEER- This is the new minimum
efficiency standard (effective Jan 2006) for an
air conditioner or heat pump. All new units
must now meet this standard.
SEER- Seasonal Energy Efficiency Ratio, an
equipment efficiency rating that measures
how much energy it takes to cool the air. As
with MPG on a car, the higher the number the
more efficient the unit.
Air Handling Unit- Equipment with a
heating element and/or cooling coil and other
components in a cabinet or casing.
Coil- A heating or cooling element made of
pipe or tubing, usually with plates or fins.
Condenser (Heat Exchanger)- The
outside unit of a heating or air conditioning
system. Here the refrigerant condenses from
a gas to a liquid and hot or cold air from the
building is released to the outside.
Duct- Conduits used to carry air. They can
be round or rectangular, sheet metal or
fiberglass or vinyl tubes.
Fan Coil- See Air Handling Unit
Furnace- A self-contained heating unit that
is designed to deliver heated air to a home.
Heat Pump- A single refrigeration system
designed to provide both heating and cooling
compared to a separate furnace and air
conditioner that only heat or cool.
Refrigerant- A fluid that absorbs heat at
low temperatures and rejects heat at higher
temperatures
Zones, Zone System- A single HVAC
system that can meet different heating and
cooling needs in different areas (zones). Each
zone of a home has its own thermostat with
which is can regulate the temperature and
humidity in its area.

		The phaseout of hydrochlorofluorocarbon (HCFC) refrigerants is nearly here, bringing change that will have a dramatic effect on the global HVAC industry. Fueled by a worldwide demand for sustainable design and environmental concern, the move to new nonchlorine hydrofluorocarbon (HFC) refrigerants calls for: - Phasing out R-22 in new equipment by January 1, 2010 - R-22 production drops significantly in 2015 - Stopping production of R-22 altogether by 2020 The leading choice to replace R-22 in air conditioning is R-410A (otherwise known as Puron), a more environmentally friendly refrigerant with zero ozone depletion and higher energy efficiency. For homeowners, R-410A means: - Reduced maintenance expenses - The most efficient systems for improved cost control - Lower energy bills R-410A is the leading choice to replace R-22 because it's simply better for the environment. It has zero ozone depleting potential and a lower global warming rating than R-22. Plus, it's been specifically designed for new systems and is far less likely to break down, under even the harshest conditions. For this reason, every major air conditioning manufacturer in the country has chosen R-410A to replace R-22 in residential and light commercial applications. New R-410A system offer up to a 5% higher Energy Efficiency Ratio (EER) and better dehumidification than older R-22 systems. AT A GLANCE- R-410A key benefits and the air conditioning systems that use it are: - Higher EER (Energy Efficiency Ratio) - Enhanced heat pump performance - Increased efficiency and reliability - Cost-effective design - Proven long-term HCFC replacement capability - No ozone-depleting chemicals - Lowest global warming Call us for your FREE in home estimate to upgrade your system to the new R-410A refrigerant today!
