About
Understanding the problem
A rooftop package unit can fail to heat for several reasons depending on whether it uses gas, electric resistance, or a heat pump. Repeated lockouts need model-specific diagnosis.
What our service assessment covers
We inspect the heating sequence and applicable safety, control, airflow, and electrical components. Gas heating equipment requires assessment of the relevant combustion and venting conditions by qualified personnel.
Before you schedule
Report the heating type, error indication, and whether the blower runs. If you smell gas, leave the area and contact your gas utility or emergency services from a safe location.
