Texas Landlord AC Repair and Habitability (2026)

105°F outside and 88°F inside is not a “wait until Tuesday” comfort problem — it is a health and sleep problem. Texas renters do not get a universal “fix AC in 24 hours” state statute, but your lease, local housing codes, and written notice still create leverage when you use them correctly.

Start with the lease maintenance clause

Highlight:

• Who maintains HVAC (landlord vs tenant filters only)
• Emergency maintenance number — call after you email
• Prohibited portable units on balconies (common in high-rises)
• Rent abatement language (rare but powerful)

Change the return-air filter if the lease assigns monthly filter duty — technicians document clogged filters and bill you.

People often ask: whether window units are allowed when central AC fails. Some leases ban them outright; others allow one unit under 15 amps with a drip pan. Violating the ban gives the landlord a lease violation unrelated to the broken central system.

Build a paper trail the same day it breaks

1. Email + portal ticket — unit number, “AC not cooling,” thermostat reading if available
2. Photos/video — thermostat, frozen indoor coil, water drip pan overflow
3. Visit log — date, name, “recharged Freon, still warm,” next steps
4. Compare to move-in photos if the unit never cooled from day one

Worth knowing: withholding rent without following Property Code notice rules can trigger eviction for non-payment even while the AC is dead — Texas courts see unpaid rent fast.

Indoor temperature logs help in disputes — a cheap indoor thermometer photo at 2 PM and 10 PM builds a record. You do not need a lab report; you need dated evidence the unit was uninhabitable for ordinary use.

City rules stack on state law

Metro	Extra layer
Austin	Housing & habitability office for code violations
Dallas	Minimum property standards when equipment is supplied
Houston	Varies by annexation and property type — search city code
San Antonio	Property maintenance division complaints

Search “[your city] property maintenance HVAC” before you assume state law alone governs.

While you wait — realistic options

• Box fans move air; they do not fix humidity
• Portable AC units — check lease weight limits and window rules
• Hotel stays — recoverable only in narrow cases; ask counsel before spending
• Cooling centers — county opens them during extreme heat; not a substitute for a lease remedy but useful for vulnerable household members

Landlords sometimes offer window film or temporary portable units while waiting for compressor parts — get any promise in writing with a completion date.

Statutory remedies (high level)

Texas Property Code §92.056 and related sections govern repair notices and certain remedies. Repair-and-deduct has dollar caps and procedure requirements — read the statute or hire help before you deduct.

Typical sequence before repair-and-deduct:

1. Written notice of the condition
2. Reasonable time to repair (shorter when health or safety is at stake)
3. Second notice if required by statute for your situation
4. Deduction capped — often the lesser of one month’s rent or $500 depending on facts and lease type

Early move-out without grounds triggers lease-break fees — do not confuse frustration with a legal exit.

Retaliation and follow-up repairs

Texas Property Code §92.331 limits certain landlord retaliation after you exercise lawful tenant rights — including repair requests. Retaliation claims are fact-heavy; keep every email.

If a technician “fixes” the AC but it fails again within days, send a second written notice referencing the prior ticket number. Repeat failures strengthen habitability arguments.

Filter duty and chargebacks

Leases that assign monthly filter changes to tenants are common in Texas. Buy the correct size, date the filter edge with a marker, and photograph installation. When maintenance finds a collapsed filter and a frozen coil, the landlord may bill you for the service call even while the central system was already failing.

Window units and lease violations during outages

When central AC dies mid-August, a portable or window unit may be your only relief — but many Texas leases ban them for aesthetic or electrical-load reasons. Using a banned unit can give the landlord a lease violation unrelated to the broken HVAC. Ask in writing whether a temporary portable is permitted while central repair is pending.

Thermostat settings matter in disputes — if the lease requires 78°F minimum during summer to reduce load, follow that rule while you document inadequate cooling.

Nighttime indoor temperatures above 85°F with infants or elderly household members strengthen urgency arguments — describe who occupies the unit when you write maintenance, without exaggerating readings.

Broader tenant context

Deposits, entry notice, and retaliation basics live in your lease and Chapter 92 — document everything the same way you would for any major repair dispute.
