Furnace or Boiler Tune-up Checklist
- Inspect, test and calibrate controls and safety mechanisms
Safety controls are designed to shut down equipment when unsafe conditions are detected in order to prevent fires, gas leaks and other dangerous situations as well as to protect the equipment from catastrophic failure. Testing and calibrating these controls ensure safe operation of your equipment.
- Lubricate motors and bearings
Lubrication prevents friction in motors which can increase electricity usage and cause equipment damage.
- Measure amperage and voltage of blower
Improper voltage and amp draw increase operating costs and can shorten the life of the system components.
- Measure and record temperatures and system performance factors
An accurate record of vital data can indicate potential problems and help prevent equipment breakdown.
- Check and adjust fan switch, pilot and pilot assembly
An improperly adjusted fan switch and/or pilot assembly can result in excess energy usage and equipment malfunction.
- Inspect and clean burners as needed
Dirty burners can cause improper combustion reducing equipment life and increasing energy usage.
- Inspect heat exchanger for deterioration and cracks
Heat exchangers can deteriorate and develop cracks with age. These cracks can result in dangerous carbon monoxide leakage.
- Measure and record carbon monoxide levels
High levels of carbon monoxide can cause carbon monoxide poisoning. Testing ensures proper emission levels and can help to identify heat exchanger cracks not detectable through inspection alone.
- Inspect gas line and flue pipe for possible leaks
This ensures proper exhaustion of toxic gases and fumes.
- Test and calibrate thermostat
Ensures that the system starts, operates, and shuts off properly.
- Check & clean air filter/replace at customer's option*
A clogged filter reduces airflow, which can cause a breakdown. It can also result in dirt and other filtered residue cycling back into your home.
- Conduct overall system assessment
This includes items such as general system configuration and ductwork/heating pipes to check for wear, damage, improper installation and other potential issues.
- Review findings, make recommendations and discuss any concerns
It's important that you understand the condition of your heating and cooling equipment including items that may pose either immediate or future risks. You should also understand your options regarding home comfort, energy efficiency and indoor air quality. Your Comfort24-7 Provider will review all of their findings and provide recommendations.
- Inspect expansion tank
- Inspect water feed valve
- Measure and record boiler pressure and temperature
- Check aquastat
- Inspect low water cut-off
- Check for backflow device
- Inspect & oil pumps
* Every system is different based on the installation, configuration and application. As a result, additional charges may apply for cleaning or adjusting components that are difficult to access or require cleaning beyond typical applications. In addition, any components that must be replaced (such as air filters or refrigerant) are subject to additional charges unless otherwise specified.
