Is air conditioning covered under car warranty?
Yes, in most cases, a new-car bumper-to-bumper warranty covers the air conditioning components for the duration of the warranty, though refrigerant charges and routine maintenance aren’t typically included. Coverage can vary by manufacturer and model.
Air conditioning is part of the vehicle’s HVAC system, and whether it’s covered depends on the type and term of the warranty, as well as the specific terms in your contract. This article explains what’s commonly covered, what’s not, and how to navigate a warranty claim.
What is typically covered in a new-car warranty
The following items are commonly included under the comprehensive or bumper-to-bumper portion of a new-car warranty, depending on the manufacturer and model. The list outlines typical inclusions you might expect to see.
- Compressor, condenser, evaporator, and associated lines and fittings
- HVAC blower motor and controls (in many cases) and related electrical components
- Hoses, sensors, actuators, and refrigerant circuitry that fail due to manufacturing defects
- Thermal expansion valve or orifice tube and other essential refrigerant circuitry that fail due to defects
Note: Refrigerant charges (R-134a, R-1234yf, etc.), dyes, and routine maintenance work like leak tests or recharge are typically excluded from warranty coverage and billed as service items unless a defect triggers the service.
What is not typically covered or may be excluded
Not everything related to the A/C system is automatically covered. Warranties typically exclude:
- Refrigerant refills and routine maintenance (service items)
- Leaks caused by wear, accidental damage, or improper maintenance
- Damage resulting from neglect, abuse, or aftermarket modifications
- Issues arising after warranty expiration or outside mileage limits
Always read the warranty terms and check for specific endorsements for HVAC or emission-related components.
How warranty terms vary and how to check yours
Warranty terms vary by manufacturer, model, and whether the car is new or certified pre-owned. The following guidance helps you verify coverage and file a claim if needed.
- Consult your owner's manual or the manufacturer's warranty booklet to see the exact coverage dates and mileage limits.
- Contact the dealer or manufacturer’s customer service for a coverage determination and authorized repair shop guidance.
- Keep all maintenance records and diagnostic reports in case a defect is disputed.
Coverage specifics can differ, so verifying the exact terms for your vehicle is essential.
What to bring when you file a claim
When filing a claim, provide proof of service, a detailed symptom description, and any diagnostic notes that support a warranty-eligible defect. A manufacturer-approved shop may conduct a diagnostic before agreeing to cover repairs.
In most cases, if a defect in materials or workmanship affects the A/C system within the warranty period, the repair is covered; routine recharging and non-defect repairs are paid by the owner.
Summary
Air conditioning components are commonly covered by new-car bumper-to-bumper warranties, with exceptions for refrigerant, routine maintenance, and issues arising outside the warranty period. Always verify the exact terms with the dealer or manufacturer, and keep service records to support any claim. As car warranties evolve, check the latest program details for your vehicle model.
Bottom line: For most new cars, the A/C system’s major components are included under the comprehensive warranty, but refrigerant services and routine maintenance are generally excluded. Warranty specifics vary, so confirm with the dealer and review the official warranty documentation.
Does a car warranty cover AC?
Your car's factory warranty will usually cover your AC compressor for about three years or 36,000 miles, whichever comes first. However, some brands offer considerably longer bumper-to-bumper coverage.
What are two items typically not covered in a car warranty?
While a bumper-to-bumper warranty covers many things, it doesn't include coverage for components that wear out or break down over time, such as your car's brakes, brake pads or tires. These are things you are expected to take care of as part of the normal maintenance of the car.
How much does it cost to fix an AC on a car?
Average cost to repair a car AC
| Repair | Average cost |
|---|---|
| AC hose repair | $350 |
| Compressor clutch replacement | $850 |
| New compressor | $800+ |
| New car AC installation or total system replacement | $2,750+ |
How can I tell if my AC is under warranty?
It is safe to bet that if your HVAC system is newer than five years old, you probably still have an active warranty on it. The easiest way to double-check this is to head over to the manufacturer's website and input the serial number for your unit. The information should pop right up.
