Why Medicare doesn't cover air conditioners
Part B covers durable medical equipment (DME) that your doctor orders for use at home, such as oxygen equipment, CPAP machines, hospital beds, walkers and wheelchairs. To count, equipment must be primarily used for a medical purpose. CMS's National Coverage Determination 280.1 lists air conditioners, along with air cleaners and room humidifiers and dehumidifiers, as environmental control equipment that isn't primarily medical, and it denies them for everyone. A doctor's letter doesn't change that, and neither does living in Phoenix in July.
Medicare also doesn't pay for repairs to a home cooling system or for electric bills.
What Medicare does cover in a heat emergency
- Emergency room care and medically necessary ambulance rides (Part B).
- Inpatient hospital stays (Part A), with a $1,736 deductible per benefit period in 2026.
- Follow-up doctor visits (Part B), and home health care if you're homebound and need skilled care afterward.
- Medical equipment that needs power, such as oxygen concentrators and CPAP machines, though not the power itself.
If you have a Medicare Advantage plan, it covers the same emergency and hospital care with its own costs. Medicare Advantage plans may offer extra benefits that Original Medicare doesn't cover, such as dental, vision, hearing or fitness. Extra benefits vary by plan and county, may have limits and costs, and not every plan offers them. Check a plan's Summary of Benefits or Evidence of Coverage.
Heat stroke is an emergency. Confusion, a very high body temperature, hot skin or fainting in the heat means call 911.
Where Arizonans can get help staying cool
- Your utility. Ask about payment arrangements, budget billing, discount programs and medical-equipment registration. The Arizona Corporation Commission's rules limit summer disconnections for customers of the utilities it regulates; Salt River Project sets its own policy.
- Energy bill help. The Arizona Department of Economic Security takes applications for the federal Low Income Home Energy Assistance Program (LIHEAP) and state energy assistance.
- 211 Arizona. Dial 211 to find cooling centers, utility help and other local services.
- Heat Relief Network. In Maricopa County, the Maricopa Association of Governments maps cooling centers and hydration stations each season, usually May through September.
- Area Agencies on Aging can connect older adults with local services; see Arizona Medicare contacts.

Frequently asked questions
Will Medicare pay for an air conditioner if my doctor says I need one?
No. Medicare's coverage list for durable medical equipment denies air conditioners and air cleaners for everyone, with or without a prescription, because they aren't primarily medical equipment.
What does Medicare cover if I get sick from the heat?
Part B covers emergency room visits, medically necessary ambulance rides and doctor visits; Part A covers inpatient hospital stays. If you're homebound afterward, Medicare can cover part-time home health care ordered by your doctor.
Can my utility shut off my power in an Arizona summer?
Arizona Corporation Commission rules protect residential customers of regulated utilities from disconnection for nonpayment during extreme heat, either with a summer moratorium or on days the National Weather Service forecasts above 95°F. Salt River Project isn't regulated by the Commission and sets its own policy. The bill still comes due afterward.
Where can I find a cooling center in Arizona?
In Maricopa County, the Heat Relief Network maps cooling and hydration sites each season. Statewide, dial 211 or check the Arizona Department of Health Services heat safety page.
