Q: What are signs that my HVAC system needs repair? A: Common warning signs include weak or uneven airflow, unusual noises (banging, squealing, or rattling), warm air from vents when cooling is set, unusually high energy bills, or the system cycling on and off frequently. If you notice any of these, it's best to call a certified technician promptly. Q: When should I replace vs. repair my HVAC unit in St. Louis? A: If your system is over 10–15 years old, requires frequent repairs, or uses outdated refrigerant, replacement is often more cost-effective.
