DIY Tips for Optimal Furnace Performance


Maintaining your furnace is crucial for ensuring its optimal performance, energy efficiency, and longevity. While it’s always recommended to seek professional assistance from experienced technicians like those at Kellerman Heating & Cooling Co., there are several DIY tips you can follow to keep your furnace in top condition.

Clean or Replace Air Filters

  1. Check your furnace’s air filters regularly and replace or clean them as needed. Clogged filters restrict airflow, causing your furnace to work harder and consume more energy.
  2. Mark your calendar to replace disposable filters every 1-3 months or clean permanent filters monthly.
  3. Ensure proper filter size and installation for optimal performance.

Clear Vents and Registers

  1. Vacuum or dust vents and registers regularly to prevent dust buildup, which can impede airflow and decrease efficiency.
  2. Move furniture or other obstructions away from vents and registers to allow unrestricted airflow.

Inspect the Furnace Area

  1. Keep the area around your furnace clean and clutter-free. Ensure there’s no combustible material or debris near the unit, which could pose a fire hazard.
  2. Check for any signs of rust, cracks, or damage to the furnace cabinet or ductwork. Promptly address any issues to prevent further deterioration.

Schedule Professional Maintenance

  • While DIY maintenance is essential, it’s crucial to have your furnace inspected and serviced by professionals at least once a year.
  • Professional technicians from companies like Kellerman Heating & Cooling Co. have the expertise and tools to perform comprehensive inspections, cleanings, and necessary adjustments or repairs.
  • Regular professional maintenance can extend the lifespan of your furnace, improve energy efficiency, and prevent costly breakdowns.


By following these DIY tips and scheduling regular professional maintenance, you can ensure your furnace operates at peak performance, providing reliable and efficient heating for your home or business. Remember, for any major repairs or concerns, it’s always best to consult with experienced technicians from reputable companies like Kellerman Heating & Cooling Co., serving the areas of Amelia, OH, Withamsville, OH, Batavia, OH, Bethel, OH, and New Richmond, OH.
