What size HVAC system should I have?
Contrary to popular belief there
really is not any rule of thumb for
sizing a HVAC system to a home. Depending
upon the construction of your home, one (1)
ton of air conditioning can cool anywhere
from 300 to 800 square feet of home. The
only way to insure the size of the system
you purchase will be large enough to cool
your home, but not any larger than you
need, is to have your home's individual
heating and cooling needs evaluated by a
Is a system with more capacity better?
No. A larger system with more capacity
delivers less comfort and costs more to
operate. An air conditioner is at its least
efficient when first turning on. A system
with too much capacity will run in numerous
short cycles, randomly just turning
on and off repeatedly, therefore causing it
to be less efficient. Also keep in mind
that an air conditioner only removes
humidity when it's running, so a system
with shorter run cycles doesn't remove
humidity from the air very well.
Can I fix the HVAC unit by myself?
Be Safe! Check power, gas, filters,
breakers, safety switches and the
thermostat. If you feel the need to open up
panels of the equipment please just
DO IT! After checking filters, breakers,
safety switches and the thermostat, there
is no need to go further. More than likely
you do not have the tools necessary to work
on the system..
