About
Understanding the problem
A rooftop unit may deliver warm air because of airflow restrictions, controls, electrical faults, economizer operation, or refrigeration problems. A thermostat call alone does not confirm the equipment is cooling.
What our service assessment covers
We evaluate the cooling sequence, supply airflow, filters, applicable economizer controls, electrical components, and refrigeration operation. Roof access and safe working arrangements are considered when scheduling.
Before you schedule
Share the unit model, thermostat status, affected area, and roof-access details. Tell us whether every zone is affected and whether the fault changes with outdoor temperature.
