Will my new furnace work differently than my old one?
We're glad you asked!
Maybe. When you install a new indoor comfort system in your home,
youšll probably notice it operates differently than your old system.
Radical changes have taken place in the technology of the comfort
industry in recent years. These changes will affect how your system
operates, and also may affect what you notice about your system.
High Efficiencies
Higher efficiencies in furnaces and air conditioners have become
increasingly 
important over the past few years. Consumers, government
agencies, and manufacturers all see higher efficiencies as a way
to conserve our natural resources while reducing consumer energy
costs. Today, furnaces are designed with high efficiency in mind.
To achieve higher efficiencies, new gas furnaces must move more
air over the heat exchanger than older furnaces so that as much
heat as possible can be sent throughout the house. The air that
comes out of your furnace registers may not seem as warm as with
your old furnace, but it will heat your house just as well. In
fact, better airflow can improve overall comfort by reducing the
differences from the ceiling to the floor, throughout your entire
home.
Add-On Air Conditioning
Modern furnaces are designed to handle high efficiency air conditioners
and must have blowers that are efficient yet powerful enough to
accommodate the add-on cooling. Since cold air is much heavier
than warm air, your system needs an extra boost from the blower
to get cool air throughout your home to provide you with efficient
total comfort during the summer. Higher air flows required for
cooling operation can contribute to unfamiliar sound levels when
your new furnace is operating, because in older homes air duct
systems were designed for heating only. Most products have multiple
speed settings to allow for the varying air needs of both heating
and cooling cycles.
Your New System: Fine-Tuned for You
Only a professional trained technician can tell you if the changes
youšve noticed are normal when upgrading from an old, inefficient
system to a new, highly efficient system. Consult with your technician
to evaluate your entire heating and cooling system. Sometimes
minor adjustments and modifications can be made to existing duct
systems to maximize comfort and minimize sound levels. These changes
are a small price to pay for the high efficiencies that mean significantly
lower fuel bills and improved total comfort!
