The shock of skyrocketing programs bills may have you considering
about changing your HVAC system…. and rightly so , because
there is no chance the fuel costs are going to head on down.
The modern heating and air conditioner systems are much more
efficient than older devices and offer significant long-term strength
savings. The federal government has mandated that any cooling models
should have a SEER ranking of at least 13 starting in 2006 and this
is good, because a twenty-year unit may well have a SEER rating of
only 7 or 8. Nevertheless , for real savings you should think of your
whole home while an energy taking in beast which needs to be put on
a diet. This includes restoring air leaks windows and door seals
It does small good to change an older HEATING AND COOLING system and expect
great reduction in bills, if you don’t attend to the areas wherever
you happen to be losing strength. HVAC afforable service are costly and
the temptation may be to just install a new high efficiency furnace
and air-conditioning system and hope for the best. The truth is, the
lowering of utility bills can be disappointing since you may
include overlooked a major player in the whole HVAC system….
like the air ducting.
A terribly designed, dripping and under insulated air ducting system
may waste 30 % or more from the money you pay to perform your
heating and cooling system. and nullify any kind of gain you could realize
by installing a fresh high efficiency program. Many duct systems
happen to be poorly protected and outflow conditioned weather into un-conditioned
attics and crawl areas. I normally find turned off ductwork
within my home inspections.
The moment ducts flow, conditioned air can be pressured out unsealed joints
and lost. Additionally , also un-conditioned air may also be drawn in
return ductwork through unsealed joints. Attic temperature can be quite
high in the summer and chilly in the winter…so, any attic room air that
enters the body through un-sealed duct joints will have to be
cooled down in the summer and heated in the winter, this increases the
load with your system and increases your energy bill.
Surprisingly an older home may possess a much better crafted duct
program than a innovative home and may only need a leak check and
efficiency upgrade. Modern homes however may be
sufferer of expense cutting methods and terribly designed duct systems.
The usage of flex duct has grown in popularity mainly because ease of
assembly and the very high cost shop made sheet material ducts.
Bend ducts also installed effectively are a poor substitute for very well
designed effectively insulated linen metal system. It is common
practice to make plenums and coil boxes out of recorded together
Be sure you include an evaluation of your duct work system in your
plans to upgrade your HVAC system. There is not any use in exhausting
valuable trained air towards the great outdoors through leaks and
worn-out duct insulation. When your duct system needs an overhaul,
you might like to consider a excessive velocity delivery system that uses
smaller sized PVC water line ducts. These high acceleration systems are much
easier to mount and insulate. The bottom line on the HVAC program upgrade
meant for maximum proficiency must incorporate more than just the new equipment.
Do not forget about the duct function and include it into your budget.
