Permit compliance
Texas requires a mechanical permit for AC installation, and only a TDLR-licensed contractor can pull it; unpermitted work can cause code violations.
Refrigerant transition
With R-410A being phased down, new systems use R-454B or R-32, which may affect compatibility and service costs.
