What Does a Furnace Tune-Up Include?

As your furnace or ductless mini split system ages, general wear and tear can cause it to stop working efficiently. And in more extreme cases, older heating systems can suddenly stop working entirely.

  • Inspection: We conduct a thorough visual inspection of the furnace, checking for any signs of wear, damage, or leaks.
  • Filter Replacement: We replace or clean the furnace filter to promote better airflow and improve indoor air quality.
  • Cleaning: We clean the burners, pilot assembly, and other crucial components to remove dirt, debris, and dust buildup that can hinder efficiency.
  • Lubrication: We lubricate the moving parts, such as motor bearings, to reduce friction and prevent unnecessary wear and tear.
  • Combustion Analysis: We perform a combustion analysis to ensure that the fuel-to-air ratio is optimal, maximizing efficiency and reducing emissions.
  • Electrical System Check: We inspect the electrical connections, controls, and wiring to ensure safe and reliable operation.
  • Thermostat Calibration: We calibrate the thermostat to ensure accurate temperature readings and efficient operation.
  • Safety Check: We perform a safety check, including testing the safety controls, gas pressure, and carbon monoxide levels, to ensure the furnace operates safely.
  • Test and Adjust: We test the furnace's startup and shutdown sequences, as well as adjust the blower speed and gas pressure if needed.
  • Recommendations and Reporting: Based on our findings, we provide recommendations for any necessary repairs or improvements, and provide a detailed report of the tune-up performed.
