Maintenance Tips

Seasonal HVAC Maintenance Checklist

• Spring tune-up (March–May)

  Schedule a professional AC tune-up before the first 80°F day. This catches worn parts and refrigerant issues before they cause a breakdown in peak season.

• Replace your air filter every 60–90 days

  A clogged filter restricts airflow, forces your system to work harder, and is the single most common cause of avoidable breakdowns.

• Clear debris from the outdoor unit

  Keep leaves, grass clippings, and mulch at least 2 feet away from your condenser so it can breathe properly.

• Test your thermostat

  Confirm heating and cooling modes both respond correctly, and replace batteries if you have a battery-powered model.

• Inspect visible ductwork

  Look for disconnected sections or obvious leaks in accessible areas like the attic or basement — even small leaks waste significant energy.

• Clean the condensate drain line

  A clogged drain line is a leading cause of AC shutoffs and water damage during humid Northwest Indiana summers.

• Fall furnace tune-up (September–November)

  Schedule your heating system inspection before the first hard freeze to catch issues while repairs are easy to book.

• Test carbon monoxide detectors

  Check detectors near sleeping areas each fall when you turn your furnace back on for the season.

• Check attic insulation and weatherstripping

  Gaps here let conditioned air escape, making your system work harder through Region winters.

• Book a maintenance plan

  Twice-yearly professional tune-ups protect your manufacturer warranty and catch small issues before they become expensive repairs.
