Performed a preferred customer furnace cleaning. Cleaned the burners and the flame sensor. Checked the furnace heat exchanger. Wiped down the inside of the furnace. Checked the electrical. Cycled the furnace and performed a furnace combustion test. No issues with the furnace at this time. Looks like the air conditioner hasn’t been serviced in a long time. Recommended getting an air conditioning cleaning to make sure the air conditioner is running properly and efficiently.

Furnace clean and tune. Cycled system. Checked heat exchanger. All chambers are showing signs of rust and corrosion. No visible cracks found with camera. Checked, removed and cleaned burners and flame sensor. Both ok. Checked and adjusted gas pressures to maximize efficiency. Preformed combustion test and found some indications of some blockage in secondary heat exchanger. No CO found in airstream. Blower motor has vibration, bearings are getting worn. System is operating normal at this time. Job complete.

Furnace clean and tune. Cycled system. Checked heat exchanger. Two chambers have deep etching in them. This is where cracks are starting to form. Checked, removed, and cleaned burners and flame sensor. Both ok. Igniter tested normal. Checked and tightened electrical connections and clamps. Cleared drain line,checked and adjusted gas pressures to maximize efficiency. Preformed combustion test. Found higher levels of XS air in exhaust. This is indicating some blockage in secondary heat exchanger. No CO found in airstream. Ventor motor bearings are worn. This is causing noisy and operation with vibration. This will seize at some point. Average life expectancy for this unit is 14 years. This unit is well past that expectation and is worn. Due to age, condition, and cost of repair, second opinion is recommended. No need to return for a pressure check, this unit is not a pulse system. Job complete.

Completed installation of a new Aprilaire 600 humidifier. Mounted the humidifier on the return air drop ductwork. Ran a water line from water heater to the Aprilaire. Installed the humidistat control on the return duct also, and wired it to the furnace and humidifier. Run tested the humidifier and found it to be operating normal.

Furnace clean and tune. Cycled system. Checked heat exchanger, found all chambers are very rusted and corroded with deep etching and cracks starting in all chambers. Checked, removed, and cleaned burners and flame sensor. Burners are very rusted and damaged. Flame sensor was also worn and corroded. Cleaned as best as I could. Found igniter worn with cracks starting. Found water in pressure switch tubing. Cleared drain lines. Found some obstruction. Ventor motor is worn. Rust damage behind Ventor motor found. Checked and adjusted gas pressures to maximize efficiency. System took 3 cycles to fire correctly. This is an indication of a possible short on main board. Preformed combustion test and found higher levels of CO in exhaust as well as elevated levels of XS air. This is a indication of blockage of secondary heat exchanger. Average life expectancy for this unit is 14 years. This unit is over 20 years old and in very poor condition. Due to age, condition, and cost of repair, second opi
