Summertime is in full swing and with the
hotter temperatures come an increase in the use of air conditioners. If you're
one of the many people who rely on an AC to keep you cool, be warned that if
your AC cooler not working properly or air conditioner not blowing cold air but
running, it can be a real headache. In this blog post, we'll give you some tips
on how to troubleshoot your AC and get it back up and running. Stay cool!
Air Conditioner not blowing cold air but running or ac cooler not working
If your air conditioner isn't working
properly, don't sweat it! Follow these tips and you'll be up and running in no
time. Or if you want to buy a new one, click here.
Check AC air filter
The air filter in your AC unit needs to
be clean in order for the unit to function properly. A clogged or dirty air
filter will restrict air flow, which can cause the unit to overheat and shut
down. To clean or replace your air filter:
1. Turn off the thermostat of your AC
unit.
2. Locate the air filter. It will be
either in the return air duct or in the blower compartment.
3. Inspect the air filter and if it is
dirty, clean it with soap and water or replace it with a new one.
4. Once the air filter is clean or
replaced, turn on your AC unit at the thermostat and check to see if it is
cooling properly.
Check AC evaporator coil
The evaporator coil is responsible for
absorbing heat from the indoor air. If this coil becomes frozen, it can
restrict air flow and cause the AC unit to shut down. To thaw a frozen
evaporator coil:
1. Turn off the thermostat of your AC
unit.
2. Locate the evaporator coil. It will be
in the blower compartment of the AC unit.
3. Inspect the evaporator coil for ice or
frost build-up.
4. If there is ice or frost build-up, use
a hair dryer to thaw the coil. Do not use an open flame!
5. Once the coil is thawed, turn on your
AC unit at the thermostat and check to see if it is cooling properly.
Check AC condenser coil
The condenser coil is responsible for
releasing heat from the refrigerant. If this coil becomes dirty, it can reduce
the AC unit's ability to release heat, causing the unit to overheat and shut
down. To clean the condenser coil:
1. Turn off the thermostat of your AC
unit.
2. Locate the condenser coil. It will be
in the outdoor unit of the AC system.
3. Inspect the condenser coil for dirt
and debris build-up.
4. If there is dirt and debris build-up,
use a garden hose to spray off the coil. Be sure to disconnect any electrical
power to the outdoor unit before doing this!
5. Once the coil is clean, turn on your
AC unit at the thermostat and check to see if it is cooling properly.
Check AC refrigerant levels
The refrigerant in your AC unit is responsible
for absorbing heat from the indoor air. If the level of refrigerant is low, it
can cause the AC unit to overheat and shut down. To check the level of
refrigerant:
1. Turn off the thermostat of your AC
unit.
2. Locate the low pressure service port.
It will be located on either the indoor or outdoor unit of the AC system.
3. Use a refrigerant pressure gauge to
check the pressure of the refrigerant. The pressure should be within the
manufacturer's specified range.
4. If the pressure is too low, you will
need to add more refrigerant. This should be done by a professional AC
technician.
5. Once the proper level of refrigerant
is restored, turn on your AC unit at the thermostat and check to see if it is
cooling properly.
Check AC for leaks
A leak in the refrigerant line can cause
the AC unit to lose its coolant and overheat. To check for leaks:
1. Turn off the thermostat of your AC
unit.
2. Locate the low pressure service port.
It will be located on either the indoor or outdoor unit of the AC system.
3. Use a leak detector kit to check for
leaks in the refrigerant line.
4. If there are any leaks, you will need
to have them repaired by a professional AC technician.
5. Once the leaks are repaired, turn on
your AC unit at the thermostat and check to see if it is cooling properly.
Clean the outdoor unit
The outdoor unit of an AC system can
become dirty over time, which can restrict air flow and cause the unit to
overheat and shut down. To clean the outdoor unit:
1. Turn off the thermostat of your AC
unit.
2. Locate the outdoor unit of the AC
system. It will be located outside, usually on a concrete pad or in a garden
area.
3. Inspect the outdoor unit for dirt and
debris build-up.
4. If there is dirt and debris build-up,
use a garden hose to spray off the unit. Be sure to disconnect any electrical
power to the outdoor unit before doing this!
5. Once the outdoor unit is clean, turn
on your AC unit at the thermostat and check to see if it is cooling properly.
Check the AC compressor
The AC compressor is responsible for
circulating the refrigerant through the AC system. If this component fails, it
can cause the AC unit to overheat and shut down. To check the AC compressor:
1. Turn off the thermostat of your AC
unit.
2. Locate the outdoor unit of the AC
system. It will be located outside, usually on a concrete pad or in a garden
area.
3. Inspect the AC compressor for any
signs of damage.
4. If the AC compressor is damaged, you
will need to have it replaced by a professional AC technician.
5. Once the AC compressor is replaced,
turn on your AC unit at the thermostat and check to see if it is cooling
properly.
Inspect the AC fans and blower
The AC fans and blower help to circulate
the air through the AC system. If these components are not working properly, it
can cause the AC unit to overheat and shut down. To inspect the AC fans and
blower:
1. Turn off the thermostat of your AC
unit.
2. Locate the indoor and outdoor units of
the AC system.
3. Inspect the indoor and outdoor fans
for any signs of damage.
4. If the fans are damaged, you will need
to have them replaced by a professional AC technician.
5. Once the fans are replaced, turn on
your AC unit at the thermostat and check to see if it is cooling properly.
Test AC thermostat
The AC thermostat is responsible for
regulating the temperature of the AC system. If this component is not working
properly, it can cause the AC unit to overheat and shut down. To test the AC
thermostat:
1. Turn off the thermostat of your AC
unit.
2. Locate the AC thermostat. It will be
located in the indoor unit of the AC system.
3. Inspect the AC thermostat for any
signs of damage.
4. If the AC thermostat is damaged, you
will need to have it replaced by a professional AC technician.
5. Once the AC thermostat is replaced,
turn on your AC unit at the thermostat and check to see if it is cooling
properly.
Check for obstructions
If there is an obstruction in the path of
the air flow, it can cause the AC unit to overheat and shut down. To check for
obstructions:
1. Turn off the thermostat of your AC
unit.
2. Locate the indoor and outdoor units of
the AC system.
3. Inspect the area around the units for
any obstructions.
4. If you find an obstruction, remove it
and turn on your AC unit at the thermostat.
5. If the AC unit is still not working
properly, you may need to contact a professional AC technician for further
assistance.
Conclusion
If your Air Conditioner not blowing cold air but running or ac
cooler not working, there are a few things you can do to troubleshoot the
issue. First, check the evaporator coil and the AC compressor. If these
components are damaged, you will need to have them replaced by a professional
AC technician. Next, check the AC fans and blower. If these components are not
working properly, they can cause the AC unit to overheat and shut down.
Finally, check the AC thermostat. If this component is not working properly, it
can cause the AC unit to overheat and shut down. If you have followed all of
these tips and your AC unit is still not working properly, you may need to
contact a professional AC technician for further assistance.
