Air Handler and Evaporator Coil Replacement in Houston
The indoor coil or air handler affects capacity, efficiency, airflow and moisture removal. Replacing only the outdoor unit without evaluating this equipment can leave compatibility and performance problems unresolved.
When indoor replacement belongs in the scope
Age, refrigerant changes, coil condition, blower performance, cabinet size and manufacturer match requirements can all make indoor replacement appropriate. Ask for the approved combination document rather than assuming the existing coil will work.
Attic access and condensate protection
Many Houston systems are in hot attics where access, platform, drain pan, float switch and drain routing matter. The estimate should explain how the old unit will be removed safely and how the home will be protected from condensate overflow.
Airflow is a startup measurement, not a guess
Duct transitions, blower setup and static pressure influence whether the new system delivers its intended performance. Ask what measurements will be recorded and how any duct restriction will be addressed.
