Signs Your Furnace or AC Needs Professional Attention

HVAC issues often start small, but ignoring them can lead to expensive repairs or system failure. Here are some common signs that it's time to call the professionals at Hely Heating and Air Conditioning Co.:

  • Inconsistent Temperatures: If you notice certain rooms are significantly warmer or colder than others, your HVAC system may be struggling with airflow issues, a faulty thermostat, or ductwork leaks.
  • Unusual Noises: Sounds like rattling, banging, or squealing often indicate loose components, motor issues, or even debris inside your system that needs immediate attention.
  • Rising Energy Bills: An unexplained increase in energy bills often signals reduced efficiency caused by dirty filters, worn-out parts, or refrigerant leaks.
  • Frequent Cycling: If your HVAC system frequently turns on and off, it could be due to an oversized system, thermostat problems, or a clogged filter restricting airflow.
  • Weak Airflow: Reduced airflow from vents can indicate a problem with the blower motor, air ducts, or clogged filters, leading to inefficient heating or cooling.
  • Foul Odors: A musty smell might mean mold or mildew in your ductwork, while a burning odor could indicate electrical issues requiring immediate attention.
  • Excessive Humidity or Dry Air: If your home feels overly humid in summer or too dry in winter, your HVAC system may not be regulating indoor air quality properly.

Ignoring these warning signs can lead to system failures or costly repairs. Call today to schedule a professional HVAC inspection in Affton, MO!
