Important
Planning tools—not an onsite diagnosis
These resources are intended to help homeowners understand and organize HVAC information. Actual equipment condition, system capacity, airflow, ductwork, electrical requirements, installation conditions and code requirements may affect the appropriate repair or replacement recommendation.
When an onsite evaluation is needed, Central HVAC can inspect the system and explain the available options based on the actual conditions in the home.
