Reasons To Call a Centennial HVAC Company

Heating Issues
- Furnace produces weak heat: Burner, ignition or airflow problems may reduce heating output.
- Heating cycles become unusually short: Thermostat problems, restricted airflow or equipment issues may cause short cycling.
- Certain rooms stay colder: Ductwork or airflow imbalances can create uneven temperatures.
- Furnace starts making new noises: Grinding, rattling or banging sounds can point to worn or loose components.
- Heating bills increase unexpectedly: Declining efficiency may force aging equipment to run longer than normal.
Cooling & AC Issues
- AC blows warm air: Refrigerant, compressor or electrical issues may interfere with cooling.
- Cooling varies between rooms: Airflow restrictions or duct problems can leave parts of the home warmer.
- Air conditioner runs continuously: Equipment may be undersized, inefficient or struggling with another performance issue.
