Maximize Comfort and Efficiency with DIY HVAC Maintenance


Proper maintenance of your heating, ventilation, and air conditioning (HVAC) system is crucial for ensuring optimal indoor comfort and energy efficiency. While it’s always recommended to have professional technicians from JTR Heating and Air Conditioning Inc. perform annual tune-ups and major repairs, there are several DIY tasks you can undertake to keep your system running smoothly.

Air Filter Replacement

  • Check and replace your air filters regularly, typically every 1-3 months, or as recommended by the manufacturer.
  • Clogged filters restrict airflow, reducing system efficiency and allowing dust and allergens to circulate.
  • Ensure you purchase the correct size and type of filter for your system.

Outdoor Unit Maintenance

  1. Clear any debris, such as leaves, twigs, or grass clippings, from around the outdoor unit.
  2. Trim back any vegetation that may be encroaching on the unit, allowing at least two feet of clearance on all sides.
  3. Gently wash the exterior of the unit with a garden hose to remove built-up dirt and grime.

Thermostat Calibration

  • Ensure your thermostat is set to the correct temperature and mode (heating or cooling).
  • If your thermostat is programmable, adjust the settings to match your schedule and preferences for optimal energy savings.
  • Consider upgrading to a smart thermostat, which can learn your habits and automatically adjust the temperature for maximum efficiency.

Ductwork Inspection

  • Visually inspect accessible ductwork for any signs of damage, leaks, or disconnections.
  • Seal any visible gaps or cracks with duct sealant or metal-backed tape to prevent air leakage.
  • Consider having a professional duct cleaning service to remove built-up dust and debris if you notice significant buildup or suspect mold growth.


By following these simple DIY maintenance tips, you can help extend the lifespan of your HVAC system, improve indoor air quality, and potentially save money on energy bills. However, for more complex issues or major repairs, it’s always best to consult with the professionals at JTR Heating and Air Conditioning Inc. to ensure the safety and proper functioning of your system.
