Nur HVAC carried out a full furnace maintenance service at this San Jose home and installed a new smart thermostat with an additional remote sensor. Our technicians worked through a complete tune-up of the heating system, cleaning, inspecting, and adjusting the unit from the burners through to the venting and controls.

What our technicians did during this furnace maintenance

• Smart thermostat installation: installed a new smart thermostat with an additional sensor and verified its operation.
• Heat exchanger and burners: inspected the heat exchanger, cleaned the burners, and cleaned the secondary heat exchanger.
• Blower and motors: checked and lubricated the fan or pump motor, measured blower motor amps, cleaned the blower, and checked system airflow.
• Combustion and safety: cleaned the pilot burner and flame rod, checked safety controls, adjusted heat rise and firing rate, and tested for carbon monoxide.
• Gas and venting: inspected the gas piping and the chimney and venting system, including a camera inspection.
• Filter, condensate, and electrical: cleaned or replaced the filter, checked and cleaned the condensate pump and lines, checked the humidifier damper, and inspected and adjusted electrical connections, the system switch, and breaker.

With the thermostat installed and every component cleaned, inspected, and adjusted, the furnace was tuned for safe and efficient operation. Every Nur HVAC furnace maintenance ends with a check of the system before we leave the home.
