Mastering DIY HVAC Maintenance – Cooling Bliss Awaits


With summer’s scorching heat just around the corner, ensuring your air conditioning system is running smoothly is crucial. While professional HVAC services from companies like Berwyn Western are highly recommended, there are several DIY tasks you can undertake to keep your unit in top shape and potentially save on costly repairs.

Air Filter Replacement

  1. Locate your air filter, typically situated behind return air grilles or in the blower compartment.
  2. Check the manufacturer’s recommendations for replacement frequency, usually every 1-3 months.
  3. Purchase high-quality air filters that match your unit’s specifications.
  4. Carefully remove the old filter and insert the new one, ensuring a snug fit.

Outdoor Unit Maintenance

  1. Turn off the power to your AC unit before attempting any maintenance.
  2. Clear away any debris, leaves, or vegetation within a 2-foot radius around the outdoor unit.
  3. Use a soft-bristle brush or vacuum attachment to gently remove dirt and clean the condenser coils.
  4. Straighten any bent fins on the coils using a fin comb tool.

Thermostat Calibration

  1. Ensure your thermostat is level and securely mounted on the wall.
  2. Check the temperature display against a reliable thermometer placed nearby.
  3. If the readings differ significantly, consult your thermostat’s manual for calibration instructions.
