National Tune-Up Day | September 25
(Last Updated On: November 8, 2022)


National Tune-Up Day on September 25th reminds homeowners to prepare for the winter heating season. 


Heating and cooling specialists recommend that homeowners tune up their heating systems every year in advance of seasonal changes. These tune-ups ensure that the systems are operating as efficiently as possible.

A heating system tune-up includes:

  • Removal of dust and dirt in your vents.
  • Checking to make sure all your vents are not blocked or leaking.
  • Ensuring your fuel jets are working correctly.

Additionally, combustion gases should be analyzed and compared to the specifications of your furnace. The blower access door needs to be checked to assure a tight seal at the furnace. Other necessary inspections include checking fresh air intake grills for blockage and burners for proper ignition and flame. While inspecting the furnace, check the drainage system for blockage and leakage, too. Drains and traps also need to be tested. Plus, the blower wheel, motor, wiring and all filters should also be checked for corrosion and damage. Heating contractors follow an extensive checklist when completing your furnace tune-up.

A heating system tune-up saves energy and reduces heating costs.


Enjoy a cozy winter. Tune up your heating system. You can also give a shoutout to the technicians who provide outstanding service. Share your experiences and use #NationalTuneUpDay to post on social media.
