Mastering DIY HVAC Maintenance for Optimal Comfort


Keeping your home’s heating, ventilation, and air conditioning (HVAC) system in top shape is crucial for maintaining a comfortable living environment. While professional maintenance is recommended, there are several DIY tasks you can undertake to ensure your JTR Energy system operates efficiently. This article will guide you through essential DIY HVAC maintenance tips to save money and prolong the lifespan of your unit.

Air Filter Replacement

  1. Locate the air filter compartment in your HVAC system, typically found near the air handler or furnace.
  2. Check the manufacturer’s recommendations for the correct filter size and type.
  3. Replace the filter every 1-3 months or as needed, depending on usage and indoor air quality.
  4. Ensure the new filter is properly secured and aligned for optimal airflow.

Outdoor Unit Maintenance

  1. Shut off power to the outdoor unit before proceeding.
  2. Remove any debris, leaves, or vegetation around the unit to ensure proper airflow.
  3. Use a soft-bristle brush or vacuum to clean the condenser coils and fins, taking care not to bend them.
  4. Straighten any bent fins using a fin comb tool.

Thermostat Calibration

  1. Check the thermostat’s settings and ensure it is programmed correctly for your desired temperature and schedule.
  2. Replace the batteries if the display is dim or unresponsive.
  3. Calibrate the thermostat by comparing its temperature reading with a separate thermometer placed nearby.
  4. Adjust the calibration settings according to the manufacturer’s instructions if necessary.

Ductwork Inspection

  1. Visually inspect accessible ductwork for any signs of damage, leaks, or disconnections.
  2. Seal any gaps or leaks with approved duct sealant or metal-backed tape.
  3. Insulate exposed ducts to prevent energy loss and condensation buildup.


Implementing these DIY HVAC maintenance tips can significantly improve the efficiency and longevity of your JTR Energy system. Remember, regular professional service is still recommended to ensure optimal performance and identify any potential issues. By staying proactive with maintenance, you can enjoy a comfortable home environment while saving money on energy costs.
