top 5 problems with your hvac system

AIR CONDITIONER
ISSUES YOU
SHOULD KNOW
ABOUT
LOW REFRIGERANT
Your air conditioner uses a refrigerant
pumped through the long tube or lines that
removes the heat and humidity from the air
in your home or business.
Leaks in the refrigerant line means the
system cannot cool the air effectively.
In this case, not only must the
refrigerant has to be placed but an
HVAC technician has to find the leak
and repair the hole in the lines.
This can’t be a time-consuming and expensive process, especially if there are
multiple leaks.
FROZEN EVAPORATOR COILS
Your air conditioner refrigerant lines
coils though an evaporator which
absorbs heat from the air like a
sponge. It sounds stange but those
coils needs warm air circulating
around them to keep the refrigerant
circulating freely.
If not, a layer of the ice build up on
the coil and you get warm air- or
noun at all- blowing through your air
registers
DIRTY CONDENSER COILS
You just read what happens,
when evaporated coils freeze
ups. Your AC is a condeser coil
in the outdoor unit get air blown
over them to remove the heat
from the coils and expel it
outside the building, but if the
coils are covered with the layer
of dirt and grime, heat tansfer is
made more difficult, which
increased wear on th parts and
even system failure.
FAN PROBLEM
Your AC unit has a two fans- one for the
evaporator coil and one for the condenser
coils outside. The both have to work well to
cool your house. If a faulty fan motors, lack of
lubrications, a worn belts or too much dirt and
debris keep fan from either working in you get
air conditioner problem. If you don’t fix the
problem then you will have to have the
compressor replaced due to failure.
LEAKING DUCTS
The cooled air is moved on the ductwrok
running through your walls and ceiling
into your room, but if the duct has a hole,
the cool air escapes and never makes it
to cool your room. Holes are common
and can be caused by chewing rodents
or careless workers. If air doesn’t get to
your room, the thermostat keeps the
system running to try to compensate,and
that drive up your energy bills.
THERMOSTAT
PROBLEMS
The thermostat especially the old dial - type
ones, to become incorrectly calibrated and
cause your air conditioner to get wrong
instruction from the control system. When
this happen your thermostat should be
replaced or recalibrated. If you have a fairly
complex programmable thermostat, it may
simply need to be set correctly. In this case,
follow the instructions in the manuals
carefully to program it correctly.
CLOGGED
DRAINS
Your air conditioner remove the
moisture from the air through
the drain lines, into the holding
pan and finally down a drain. If
the line or drain gets clogged,
then the holding pan can get
full, and water can backup and
damage your system, not to
mention to leaking out of the
pans to damage your walls,
ceiling and even your
furnishings. If it’s not corrected
right away, the mold growth will
compound the problem.
