Full System Precision Tune up and Safety Inspection Checklist
- Carbon Monoxide Test - Peace of mind against
toxic fumes
- Check and adjust thermostats (calibrate) - An
improperly calibrated thermostat can cause your system to run longer and
less efficiently.
- Also affects comfort levels
- Check Safety controls - Prevents premature
failures and increases efficiency
- Clean Safety controls (if needed) - Prevents
premature failures and increases efficiency
- Clean the burners - Dirty burners cause poor
combustion leading to inefficient operation and wasted fuel and money
- Clean the burner controls - Dirty burners cause
poor combustion leading to inefficient operation and wasted fuel and money
- Clean and adjust pilot assembly - A weak or dirty
pilot assembly can easily be extinguished causing the furnace to shut down
- Check flame sensor - - A weak or dirty flame
sensor can easily be extinguished causing the furnace to shut down
- Clean flame sensor (if needed) - - A weak or
dirty flame sensor can easily be extinguished causing the furnace to shut
down
- Check fan switch - A properly operating fan
switch increases efficiency and prevents annoying fan cycling
- Check for gas leaks - No one wants a gas leak
- Check gas pressure – Insures efficient ignition
and burn. Saves you money.
- Check filter - A dirty or plugged filter can
increase operating cost and reduce the lifetime of the equipment – check
every month and
replace when dirty
- Replace Pilot Safety - A faulty pilot safety will
shut the furnace down
- Check blower motor - Dirty motors operate less
efficiently and will fail sooner
- Clean blower motor (if needed) - Dirty motors
operate less efficiently and will fail sooner
- Check inducer motor - Dirty motors operate less
efficiently and will fail sooner
- Clean inducer motor (if needed) - Dirty motors
operate less efficiently and will fail sooner
- Check belts and adjust tension - Loose belts
decrease air flow, increase operating costs and shorten the life of your
unit
- Lubricate all parts- Prevents premature failures
- Check Flue for proper venting - Problems with the
Flue pipe can be dangerous
- Check Combustion air intakes - Problems with
combustion air openings can be dangerous
- Check condensate drain - Condensate drains can be
plugged, leak and lead to expensive water damage
- Check drain lines - Drain lines can be plugged, leak
and lead to expensive water damage
- Inspect wiring - Loose wiring can lead to a
failure of the system
- Inspect heat exchanger - Heat exchangers can
develop cracks with age, leading to exposure from carbon monoxide
- Check and record temperatures - A history of your
equipment’s data can help prevent problems
- Check operating pressures - A low or high
refrigerant charge can easily go unnoticed and increase operating costs
and can lead to compressor shut down
- Check refrigerant charge - A low or high
refrigerant charge can easily go unnoticed and increase operating costs
and can lead to a compressor shut down
- Check Voltage of compressor - Improper operation
of mechanical parts can lead to premature failure and decrease efficiency
- Check Amp Draw of compressor - Improper operation
of mechanical parts can lead to premature failure and decrease efficiency
- Check Voltage of fan motor - Improper operation
of motors can lead to premature failure and decrease efficiency
- Check Amp Draw of fan motor - Improper operation
of motors can lead to premature failure and decrease efficiency
- Check evaporator coil - A dirty coil increases
operating costs, decreases efficiency and contributes to compressor
failure
- Clean evaporator coil (if needed) - A dirty coil
increases operating costs, decreases efficiency and contributes to
compressor failure
- Check condenser coil - A dirty coil increases
operating costs, decreases efficiency and contributes to compressor
failure
- Clean condenser coil - A dirty coil increases
operating costs, decreases efficiency and contributes to compressor
failure
- Check air flow across evaporator coil - Poor air
flow can lead to increased operating costs and contribute to a system
freezing up
- Check air flow across condenser coil - Poor air
flow can lead to increased operating costs and contribute to a system
freezing up
- Check contactors - Bad contactors can lead to
compressor and motor failures
- Check capacitors - Bad capacitors can lead to
compressor and motor failures
- Inspect system disconnect - A worn or over-heated
disconnect can lead to blown fuses and dangerous operation
- Check Ignition Transformer (oil) - If the
transformer is weak, you might have improper ignition
- Check Flame Detector (oil) - Prevents annoying
lockouts
- Take Draft Test (oil) - Insures proper draft
across heat exchanger insuring maximum efficiency
- Perform Smoke Test (oil) - Insures proper burn
leading to maximum efficiency
- Perform Bacharach Test (oil) - Checks for proper
burner efficiency
- Replace Oil Filter (oil) - Insures clean oil in
system insuring proper burn
- Replace Nozzle (oil) - A worn nozzle will operate
inefficiently
- Check Electrodes (oil) - Insures proper ignition
- Remove any debris or foliage from inside or
around the condenser
