We
believe in order for you to make the right decision you should know
how a system is designed. When a home is going to be considered for
a system install or replacement, there needs to be a heat load calculation
done.
A
heat load calculation is where we measure every wall, window, door,
ceiling, and floor in your home. We then take all of those measurements
in square feet and put them into a calculation table called a “Manual
J”. This comes out with the exact BTU requirements of your home.
That is, how much heat it takes to warm up the home in the winter. And
how much cooling is required to take the heat away in the summer.
Many
companies do not do this; they rely mostly on guess work or they just
duplicate the system that's already in place. This short cut "guesstimation"
often results in a system that is not adequate for the home. Replacing
an existing inadequate system with another is what happens when a heat
load calculation is not completed.
After the load calculations are done then the ductwork and pipe sizing
needs to be addressed. If it is a forced air system, we take into consideration
the CFM (Cubic Feet per Minute) requirements and the static pressure
and velocity requirements for the ductwork. This is the only way to
be certain that there will be enough air going trough the unit to do
the job without it sounding like a plane taking off at the Manchester
airport. If the air coming out of the vents is loud, it's typically
because they're not sized correctly.
Next
we deal with the requirements for exhaust vent sizing, A/C line set
sizing, unit placement, and clearances. There are then numerous
unit options that come into play into getting you the right system
for your unique situation.
If any of these steps are not followed closely, it is a guarantee that
you will have problems with your system. Problems that include: hot
or cold spots, uneven temperatures, uncomfortable noise, system freezes,
premature system failures, cracked heat exchangers, and constant thermostat
adjustments. These are all fairly common problems with incorrect system
designs.
While providing you with this service you'll gain confidence in our
ability to meet your needs and you'll be comfortable knowing you're
choosing a reliable company to
do the work. We promise you will not be disappointed, and we count on
your satisfaction to refer us to our next job.
