Furnace Cleaning Checklist
What is included in our furnace cleaning/tune up service?
- Carbon monoxide check
- While rare, cracked heat exchangers can lead to carbon monoxide entering the home. We’ll check your CO levels to identify any problems.
- Check CO detectors
- Carbon monoxide monitors typically have a service life of 5 or 10 years. We’ll check the expiration date of the monitors in your home.
- Measure amp draw
- This is the best way to identify a strained system. As the motor struggles to spin due to bad bearings or other issues, the amperage will increase. This figure gives us a good picture of the service life of the blower motor.
- Clean induction fan tube
- Combustion in your furnace creates particular matter that will eventually clog key components of your system. We’ll clean these to ensure the maximum life of your equipment.
- Inspect and clean burner
- Burners accumulate debris over time and require regular cleaning to maintain efficiency
- Inspect heat exchanger for cracks or leaks
- As the name implies, the heat exchanger passes the energy from the burning gas to the air inside your home. If it’s cracked, exhaust and combustion fumes can enter your home. We’ll check to ensure it’s operating correctly.
- Static pressure test duct system
- Furnaces are designed to work within a specific range of pressure. If this pressure is exceeded the energy required will increase and the lifespan of the equipment can diminish. We’ll check to ensure the system is within the recommended specs for your system.
- Conduct full operational test
- Our technician will run the furnace through the full range of operating modes and fan speeds.
- Inspect condensate drain and clear, if needed
- Modern, high efficiency furnaces contain condensate pumps to remove water created during the combustion process. Over time, these become clogged with debris and can force the furnace to stop.
- Test exhaust system
- Older, low efficiency furnaces can suffer from deteriorated exhaust flues due to the caustic nature of the compounds. We’ll examine the exhaust duct for leaks or deterioration.
- Clean interior of the furnace
- Verify and adjust gas pressure
- Test ignition system
- Test the thermocouple
- Change air filter
- Test carbon monoxide levels
- Voltage and current checks
What isn’t included?
- Replacing parts. If we identify broken or malfunctioning equipment, we’ll provide a quote for the replacement.
- For certain models, removal of the blower motor is extremely time consuming and involves major disassembly. If we determine it’s important, we’ll discuss the extra time/charge required before proceeding.
- Heat pump, AC or mini-split cleaning. This equipment requires much more time to clean and carries an additional charge.
