Be Aware of the Common HVAC Danger Signs to Look For

HVAC Danger SignsHVAC danger signs may grab your attention or they may be subtle and easy to miss. Awareness of these issues can help ensure you get the reliable cooling and heating that you need when you need it, as well as prevent potentially expensive damage to system components. Being alert to HVAC danger signs may also protect you from actual safety hazards. Read on for a list of warning signs to be aware of.

  • The system turns on and off rapidly. Known as “short cycling,” this is one of the HVAC danger signs that is linked to several issues. If it’s a new AC or furnace, short cycling usually indicates that the BTU capacity of the unit is not properly sized to accommodate the home’s square footage. Short cycling can also mean the unit is overheating for some reason due to obstruction in the system airflow or a defective component like the AC compressor.
  • Energy bills are steadily rising. Low refrigerant in the AC — usually due to a leak — causes extended cooling cycles, increases electrical consumption, and boosts monthly bills. Mounting heating costs may result from a furnace that needs maintenance such as burner adjustment or cleaning. Aging cooling and heating units with declining energy efficiency inflict increasing operating costs as time passes.
  • Uneven cooling and heating. If some rooms are always too hot or too cold, something’s probably amiss. Leaky ductwork — or disconnected duct segments — can reduce or stop air circulation into one or more rooms. Alternatively, one or more internal dampers inside ductwork may have closed.  A clogged air filter may also restrict airflow, reducing circulation in rooms that are farthest from the air handler.
  • Smell of rotten eggs. It’s the pungent, hard-to-miss warning of leaking natural gas. Natural gas leaks may originate from the home’s furnace, kitchen stove, or water heater. Inhaling natural gas can cause unconsciousness and death. It also poses an immediate danger of explosion or fire. If you notice this odor, get everyone outside and call the fire department or your local gas company.
