Air Filter Replacement

One of the most important and easiest DIY tasks is replacing your HVAC system’s air filter regularly. A clogged air filter can significantly reduce the system’s efficiency and lead to higher energy bills. Here are the steps to follow:

  1. Locate the air filter compartment (usually found near the indoor unit or in the return air duct).
  2. Note the size and type of the existing filter.
  3. Purchase a new filter of the same size and type.
  4. Remove the old filter and insert the new one, ensuring it’s properly seated.
  5. Set a reminder to replace the filter every 1-3 months, depending on the manufacturer’s recommendations.

Outdoor Unit Maintenance

The outdoor unit of your HVAC system is exposed to various elements, making it susceptible to debris accumulation and potential damage. Follow these steps to keep it in good condition:

  1. Clear away any leaves, twigs, or other debris from around the unit.
  2. Trim back any vegetation that may be encroaching on the unit.
  3. Inspect the unit for signs of rust, corrosion, or damage.
  4. Clean the condenser coils by spraying them with a coil cleaner, following the manufacturer’s instructions.
  5. Ensure the unit is level and stable, and check for any loose or damaged parts.

Thermostat Calibration

A properly calibrated thermostat is essential for maintaining the desired temperature in your home while optimizing energy efficiency. Here’s how to calibrate your thermostat:

  1. Locate the thermostat and carefully remove the cover.
  2. Check the manufacturer’s instructions for calibration procedures.
  3. Use a separate thermometer to measure the room temperature and compare it to the thermostat setting.
  4. Adjust the thermostat according to the manufacturer’s instructions if there is a discrepancy.
  5. Replace the cover and test the thermostat by adjusting the temperature settings.
