Short answer
Heat-related comfort and health concerns deserve prompt fact gathering. Texas repair duties depend on the condition and statutory criteria, not a universal repair clock.
What to do next
Document indoor conditions, the equipment fault and any vulnerable occupants, then arrange qualified assessment.
Save the current lease, dated messages, receipts and any property-specific evidence together. A useful record shows what happened, when it happened and which document or rule you relied on.
Check the source
Rules may change and the right answer can depend on the home, city, lease and timing. Review the current official material before signing, charging a fee, sending a notice or making a legal decision.
