EXCHANGER inspected for cracks and deterioration:
|
BURNERS
cleaned:
- Dirty
burners can cause poor combustion, which reduces efficiency and
can be a safety hazard.
|
THERMOCOUPLE
replaced:
- The
thermocouple is a safety device and can cause the furnace to
shut down unexpectedly. We won't take a chance with
your comfort & safety. It is replaced before it causes a problem.
Newer furnaces have flame sensors instead of thermocouples and
require periodic cleaning.
|
ELECTRONIC
IGNITION CONTROLS tested & cleaned:
- Most
of the newer furnaces have electronic ignition controls that
are responsible for lighting the burners, sensing a flame
is present and provide safety shutdown if conditions require.
|
FAN
SWITCH checked and adjusted as needed:
- A
fan switch that is not properly adjusted can waste energy or
cause
nuisance fan cycling. PILOT cleaned and adjusted as necessary.
Weak or dirty pilots can easily be extinguished causing the furnace
to shut down.
|
SAFETY
CONTROLS operationally checked:
- Safety
controls that do not operate can cause dangerous problems.
|
BLOWER
WHEEL inspected:
- Dirty
blower wheels reduce airflow, causing longer operating time and
increased cost.
|
|
GAS
LINE checked for leaks from the furnace shut off valve to the
burners:
- Undetected
gas leaks are dangerous.
|
COMBUSTION
AIR openings checked:
- Blocked
or restricted combustion air openings can be dangerous.
|
FLUE
PIPE inspected:
- Flue
pipe corrosion or leaks are dangerous.
|
MOTORS
cleaned, lubricated (if possible), inspected and tested:
- Dirty
non lubricated motors run hotter, less efficient and will fail
sooner.
|
BLOWER
MOTOR SPEED checked for proper speed setting:
- Indoor
blower speed will be checked to assure proper airflow. A furnace
with inadequate airflow (too low a speed setting) can
cause premature failure of the heat exchanger and create unsafe
conditions in your home.
|
CAPACITORS
tested:
- Capacitors
work together with motors and without a properly functioning
capacitor the motor can stop running, run hot or fail.
Most of the time a capacitor will slowly loose its capacity over
time and therefor a test is performed to determine how much loss
there is, if any.
|
THERMOSTAT
checked:
- Malfunctioning
thermostats can run equipment too long or short a time for optimum
operation and comfort. You can have
the best equipment in the world, but if you control it with a "standard" thermostat,
you will not achieve the potential efficiency and comfort the equipment
is capable of.
