Warning Signs
When Should You Call for HVAC Service?
You do not have to wait until your system completely breaks down. In Upstate South Carolina, small HVAC problems can quickly become major comfort issues. Call Three Jay Heating & Air if you notice any of these signs:
Your AC is blowing warm or weak air
Your heater is blowing cool air
Your system turns on and off too frequently
Certain rooms are hotter or colder than others
Your energy bills are rising unexpectedly
Your thermostat is not reading correctly
Your system runs constantly without stopping
You hear grinding, buzzing, rattling, clicking, or banging
Water is leaking around your indoor unit
Ice is forming on AC components or refrigerant lines
Your home feels humid even when the AC is running
Your HVAC equipment is 10 to 15 years old or older
Some problems may be simple. Others can point to failing components, airflow restrictions, duct issues, aging equipment, or efficiency loss. Either way, we will inspect the system, explain what we find, and help you decide the best next step.
