What the law says about air conditioning

Whether a landlord must provide air conditioning depends on your state and sometimes your city. Most states do not require it as part of the basic habitability standard — unlike heat in winter, which nearly every state mandates. However, some states and cities have added air conditioning to their rental codes, and a few treat it as required when the building already has a system installed.

The safest approach is to check your state's residential tenancy laws and your city or county housing code directly. Your state attorney general's office or housing authority can tell you what applies where you live. If your lease mentions air conditioning — whether it says the landlord will provide it or that you will maintain it — that contract language overrides the baseline legal requirement in most cases.

Even where air conditioning is not legally required, a landlord cannot remove a working system or let it fail deliberately if it was part of the rental agreement when you moved in. That crosses into breach of contract and, in some jurisdictions, constructive eviction if the heat becomes dangerous.

Key Takeaways

  • Most states do not require landlords to provide air conditioning, but some states and cities do — check your local housing code to know for certain.
  • If your lease says the landlord will provide or maintain air conditioning, that agreement is binding regardless of what state law says.
  • A landlord who removes a working air conditioning system or lets it break down deliberately may be in breach of contract, even in states where AC is not legally required.
  • Repair timelines vary by state; some require fixes within days, while others give landlords longer — your lease may set a faster standard.
  • If your unit becomes dangerously hot and the landlord will not fix the system, you may have the right to repair it yourself and deduct the cost from rent, depending on your state.

States and cities that require air conditioning

Arizona requires landlords to maintain air conditioning in rentals, reflecting the climate and the genuine health risk of extreme heat. New Mexico has similar rules. Some California cities, including parts of Los Angeles and San Francisco, have added air conditioning to their habitability standards in recent years, though California state law does not yet require it statewide.

Washington, D.C. requires landlords to maintain air conditioning systems that are already installed. A handful of other cities have local codes requiring it, but these are exceptions rather than the rule. The majority of states treat air conditioning as a luxury amenity, not a required utility.

Your lease is often more important than state law. If you signed a lease that lists air conditioning as included, the landlord is bound by that contract even if your state does not legally require it. Read what you signed carefully — sometimes leases say "air conditioning available" rather than "provided," which shifts the burden to you.

What counts as a working air conditioning system

A working system means the unit cools the space to a reasonable temperature and does so without posing a safety hazard. Most state codes that do require air conditioning do not specify an exact temperature — they say the system must function and be maintained in good repair. A unit that runs but cools only to 85 degrees when outside is 95 degrees may still meet the legal standard in some places, though a unit that does not cool at all does not.

If your air conditioning breaks, the landlord's obligation to repair it depends on your state's repair timeline rules. Some states require repairs within 24 to 48 hours if the heat poses a health risk. Others give landlords longer — sometimes 7 to 14 days — for non-emergency repairs. Check your state's residential tenancy act or ask your local housing authority what timeline applies to you.

A landlord cannot charge you to repair a system that was working when you moved in, unless your lease explicitly says you are responsible for maintenance. Wear and tear is the landlord's responsibility; damage you caused is yours.

What to do if your air conditioning is broken

Start by notifying your landlord in writing — email counts, but a text message is safer because it creates a time-stamped record. Describe the problem clearly: "The air conditioning unit in the bedroom stopped cooling on June 15. The temperature inside is now 88 degrees." Include the date and time. Do not assume a phone call is enough; landlords often claim they never heard about the problem.

Give the landlord a reasonable time to respond and repair. If your state requires repairs within 48 hours and the landlord does not act, you have options. Some states allow tenants to repair the system themselves and deduct the cost from rent — this is called the "repair and deduct" remedy. Others require you to contact a local housing inspector or file a complaint with the housing authority first. A few states allow you to withhold rent entirely until repairs are made, though this is riskier because it can trigger an eviction case.

Do not repair the system yourself or hire someone without understanding your state's rules first. In some places, you can deduct reasonable repair costs from rent. In others, you cannot — and if you do, the landlord can evict you for non-payment. Your local housing authority or a tenant rights organization can tell you what your state allows.

When heat becomes a habitability issue

If your apartment becomes dangerously hot — typically above 90 degrees indoors for an extended period — and the landlord will not fix the air conditioning, you may have grounds to break the lease or withhold rent, depending on your state. This is called constructive eviction: the unit becomes uninhabitable, so you are no longer bound by the lease.

To use this defense, you usually have to prove three things: the condition is serious enough to make the unit unlivable, you notified the landlord in writing, and the landlord did not fix it within a reasonable time. You also typically have to move out within a short window — usually 30 days — or you lose the right to claim constructive eviction.

This is a serious step and can result in an eviction case if the landlord disputes it. Before you break a lease on these grounds, contact a local tenant rights organization or legal aid office to understand how your state's courts treat this claim. In some places it is a strong defense; in others it is harder to prove.

Air conditioning in your lease: what language matters

If your lease says "air conditioning included" or "landlord maintains air conditioning," the landlord is bound by that promise. If it says "air conditioning available" or "tenant responsible for air conditioning," you are responsible for repairs and maintenance. Some leases say nothing about air conditioning at all, which means the state law for your area applies.

If you are signing a new lease and air conditioning matters to you, ask the landlord to add specific language: "Landlord will provide and maintain a working air conditioning system" or "Tenant is responsible for all air conditioning repairs." Get it in writing. A verbal promise does not hold up in court.

If your lease is silent and your state does not require air conditioning, the landlord has no legal duty to provide it — but if a system was already there when you moved in, the landlord usually cannot remove it or let it fail deliberately without breaching the implied covenant of habitability.

Frequently Asked Questions

Can a landlord turn off the air conditioning to save money?

No, not if the lease says air conditioning is included or if your state requires it. If the system is installed and was working when you moved in, the landlord cannot shut it off deliberately. If your state does not require air conditioning and your lease does not mention it, the landlord has more leeway — but deliberately making the unit uninhabitable can still violate habitability laws.

What if my landlord says I have to pay for air conditioning repairs?

If the system was working when you moved in and you did not damage it, the repair is the landlord's responsibility in most states. If your lease says you are responsible for maintenance, the landlord may be able to charge you — but check your state law first, because some states do not allow landlords to shift maintenance costs to tenants for systems the landlord owns.

Can I withhold rent if the air conditioning is broken?

It depends on your state. Some states allow rent withholding for serious habitability problems; others require you to use repair-and-deduct or file a complaint with the housing authority first. Do not withhold rent without understanding your state's rules — it can trigger an eviction case. Contact your local housing authority or tenant rights group before you do this.

What if my landlord says air conditioning is not required where I live?

They may be right — most states do not require it. But if your lease says it is included, the lease overrides state law. If your lease is silent and your state does not require it, the landlord has no legal duty to provide it. Check your state's housing code and your lease language to be sure.

How long does a landlord have to fix a broken air conditioning unit?

It varies by state. Some states require repairs within 24 to 48 hours if the heat poses a health risk; others allow 7 to 14 days for non-emergency repairs. Check your state's residential tenancy act or contact your local housing authority to learn the timeline that applies to you.
