Hands-On HVAC Maintenance for Homeowners


Keeping your home’s heating, ventilation, and air conditioning (HVAC) system in top shape is crucial for maintaining a comfortable living environment and saving energy costs. While professional service from companies like Astro Air Inc. is recommended for major repairs and installations, there are several DIY tasks you can perform to ensure your HVAC system runs smoothly.

Air Filter Replacement

  1. Locate the air filter compartment, usually near the indoor unit or return air duct.
  2. Remove the old filter and note the size and type for replacement.
  3. Vacuum the area around the filter compartment to remove any accumulated dust or debris.
  4. Insert the new filter, making sure it’s properly aligned and secured.

Outdoor Unit Cleaning

  1. Turn off the power to the outdoor unit.
  2. Use a soft-bristle brush or a garden hose with a gentle spray to remove dirt, leaves, and debris from the unit’s exterior.
  3. Clear any obstructions around the unit, allowing for proper airflow.
  4. Check for any visible signs of damage or wear and address them accordingly.

Thermostat Adjustments

  • Set your thermostat to a temperature that suits your comfort level while saving energy.
  • Consider installing a programmable thermostat to automatically adjust temperatures when you’re away or asleep.
  • Clean the thermostat’s exterior and replace the batteries if necessary.

Duct Inspection and Sealing

  1. Inspect the ductwork for any visible gaps, holes, or disconnections.
  2. Use duct sealant or metal-backed tape to seal any leaks or cracks.
  3. Ensure that insulation is intact and not damaged, as this can lead to energy loss.
