When your furnace or air conditioner won’t start, that’s a sure sign that your HVAC system needs repairs. A spike in energy bills, or unusual noises or smells coming from the unit or vents are also strong indicators. But several warning signs are often less obvious. How do you know when your HVAC needs repair?


Signs that you have a problem include: 

  • On days without extreme heat or cold, the HVAC seems to be cycling too frequently.
  • The heater or air conditioner turns off before it’s reached the right temperature. 
  • It’s blowing warm air when cool air should be coming out.
  • Your home or business is very humid even though the AC is running.
  • People’s allergies are flaring, especially when they’re inside.
  • You notice ice or moisture inside the AC unit.
  • Water or freon is leaking from the unit.
  • The airflow from the vents is weak.
