Common signs your HVAC system needs repair include weak or uneven airflow, warm air from AC vents, cold air from heating vents, strange noises, foul smells, frequent cycling on and off, ice on refrigerant lines, water around the indoor unit, and energy bills rising without a change in use.

Watch for these symptoms

  • Air doesn’t feel cold (or hot) the way it should
  • Weaker than usual airflow
  • System short-cycles — turning on and off rapidly
  • Banging, grinding, or screeching noises
  • Burning smell or musty odor when running
  • Ice or frost on refrigerant lines
  • Water or leaks around indoor equipment
  • Rising energy bills

Don’t wait for a full breakdown. Schedule a diagnostic through furnace repair or AC repair, or call our emergency HVAC line if it’s after hours.
