Understanding AC Warranties: What’s Covered and What’s Not

Purchasing a new air conditioning (AC) system is a major investment, and with that investment comes a natural desire to protect it. That’s where AC warranties come in. An AC warranty provides peace of mind by covering repairs or replacements due to defects, malfunctions, or early wear. However, not all AC warranties are created equal, and understanding what is covered—and what’s not—is crucial for homeowners.

Knowing the scope of your AC warranty can help you avoid unexpected repair costs and make informed decisions about maintenance and repairs. In this guide, we’ll break down the key components of AC warranties, common exclusions, and how to keep your warranty valid.

Types of AC Warranties
AC warranties come in different forms, each covering specific aspects of your unit and installation. Here are the most common types of warranties you’ll encounter when purchasing a new AC system:

1. Manufacturer’s Warranty: The manufacturer’s warranty covers the cost of repairs or replacement due to defects in materials or workmanship. This warranty typically applies to major components, such as the compressor and coil, and can range from five to 10 years, depending on the manufacturer.
2. Parts Warranty: Some manufacturers offer a separate parts warranty, which covers individual components of the AC unit, such as the fan motor, circuit boards, and capacitors. Parts warranties usually last between five to 10 years. In some cases, homeowners may need to register their unit with the manufacturer to activate the full length of the warranty.
3. Labor Warranty: While parts may be covered by the manufacturer, the labor required to install or replace those parts is often not included. A labor warranty, sometimes provided by the HVAC company that installs the unit, covers the cost of labor for repairs or replacements. Labor warranties typically last for one to two years but can sometimes be extended.
4. Extended Warranty: Some manufacturers or HVAC companies offer extended warranties that provide additional coverage beyond the standard warranty period. Extended warranties can cover both parts and labor, offering a safety net for repairs in the years following the initial warranty period. These warranties come at an additional cost and may require maintenance requirements to remain valid.

Understanding the type of warranty your AC unit has is essential for knowing what to expect in terms of coverage and duration. Most units come with at least a manufacturer’s warranty, but some systems may also include parts or labor warranties depending on the brand and installer.

Common Coverage in AC Warranties
A standard AC warranty usually covers major components of the system that are prone to wear or failure over time. Here are some of the most commonly covered components:

• Compressor: The compressor is the heart of the AC system, responsible for circulating refrigerant to cool your home. It’s a critical component, and most manufacturer warranties cover the compressor for five to 10 years.
• Evaporator and Condenser Coils: These coils are responsible for absorbing heat from inside your home and releasing it outside. Both the evaporator coil (inside the home) and the condenser coil (outside) are typically covered under the manufacturer’s warranty.
• Fan Motor: The fan motor helps circulate air through the AC system. Many parts warranties cover the fan motor, which can be a costly part to replace if it fails.
• Thermostat: While not always included, some AC warranties extend coverage to the thermostat if it is purchased as part of the system.
• Circuit Boards and Electrical Components: These components control the operation of your AC unit, and many parts warranties include them in the coverage.

It’s essential to read the warranty terms carefully to understand which parts are covered and for how long. Additionally, some manufacturers offer longer warranties for certain high-end models or energy-efficient units, so be sure to check if your AC qualifies for extended coverage.

Common Exclusions and What’s Not Covered
While AC warranties offer valuable coverage, there are certain things they typically don’t cover. Understanding these exclusions can help you avoid unpleasant surprises when you need repairs or replacements. Here are some of the most common exclusions in AC warranties:

1. Regular Maintenance: Warranties do not cover routine maintenance, such as cleaning coils, replacing filters, or checking refrigerant levels. Regular maintenance is essential for keeping your AC system running smoothly, but it’s the homeowner’s responsibility to ensure these tasks are completed.
2. Labor Costs: As mentioned, most manufacturer warranties cover parts but not labor. This means you’ll be responsible for paying a technician to install any replacement parts. Labor warranties from your HVAC installer can help offset these costs, but they are generally shorter in duration.
3. Damage Due to Improper Installation: If the AC unit was installed incorrectly, the warranty might be voided. Manufacturers require professional installation to ensure the unit operates safely and efficiently. If improper installation leads to damage, the manufacturer may refuse to honor the warranty.
4. Refrigerant Replacement: Some warranties do not cover refrigerant or refrigerant recharges. If your unit leaks refrigerant due to a manufacturer defect, the replacement part might be covered, but you may need to pay for the refrigerant itself.
5. Damage from External Factors: AC warranties often exclude damage caused by external factors, such as weather events (floods, lightning, etc.), power surges, and pests. Protecting your AC unit from these potential hazards can help avoid costly repairs that aren’t covered under warranty.
6. Improper Use or Neglect: If your AC system is damaged due to improper use or neglect, such as not changing filters or blocking airflow, the warranty may not cover repairs. Manufacturers expect that the unit will be used according to guidelines, so following these recommendations is essential.
7. Aftermarket Parts: Some warranties exclude coverage if non-OEM (original equipment manufacturer) parts are used for repairs. Always verify that replacement parts are approved by the manufacturer to avoid voiding the warranty.
8. DIY Repairs: Attempting to repair your AC system yourself can void the warranty. Most manufacturers specify that only certified HVAC technicians can work on the unit to ensure proper repairs and safety.

Knowing these exclusions can help you plan for additional costs and avoid actions that could void your warranty. Regular maintenance, professional installation, and adhering to manufacturer guidelines are key to maximizing the value of your warranty.

How to Keep Your AC Warranty Valid
To ensure your AC warranty remains valid, there are a few critical steps you should take. Proper care and adherence to warranty terms will give you peace of mind that your system is protected if any covered issues arise. Here’s what you need to do to keep your warranty intact:

• Register Your Warranty: Some manufacturers require you to register your AC unit shortly after purchase to activate the full warranty coverage. Typically, this must be done within 60–90 days of installation, so don’t delay. Failure to register may result in a shorter warranty period.
• Schedule Regular Maintenance: Many warranties require proof of regular maintenance, usually at least once a year, to remain valid. Hiring a licensed HVAC professional to perform annual maintenance will not only keep your system running efficiently but will also satisfy warranty requirements.
• Use Certified Technicians for Repairs: If you need repairs, make sure you hire a licensed and certified HVAC technician. Using an uncertified technician can void your warranty, as manufacturers require professional service to ensure repairs are performed correctly.
• Keep Records: Save all receipts, records, and invoices for maintenance, repairs, and installation. Having proof of regular maintenance and repairs by certified technicians can be crucial if you ever need to file a warranty claim.
• Avoid DIY Repairs: While it may be tempting to try fixing minor issues yourself, DIY repairs can void the warranty. Any repairs or replacements should be handled by a licensed professional to ensure compliance with warranty terms.

Following these steps will help you protect your investment and ensure your warranty remains valid for the duration of its term.

The Benefits of Extended Warranties
If you want additional peace of mind, consider purchasing an extended warranty for your AC system. Extended warranties can provide extra coverage beyond the standard manufacturer’s warranty, often covering both parts and labor for an extended period. This can be especially beneficial if you’re concerned about the long-term costs of repairs or if you live in an area with extreme weather conditions that may put more strain on your AC unit.

While extended warranties come at an additional cost, they can be worth the investment for high-end or expensive systems, as they provide a safety net for unexpected repairs. Before purchasing an extended warranty, carefully review the terms, as some plans may have exclusions similar to standard warranties.

Making a Warranty Claim
If you experience an issue covered by your AC warranty, here’s how to file a claim:

1. Contact Your HVAC Technician: Reach out to the HVAC company that installed your system or a certified technician authorized to handle your AC brand. They can diagnose the problem and confirm whether it’s covered under warranty.
2. Provide Documentation: Be prepared to show proof of purchase, maintenance records, and warranty registration if requested. Having organized records can expedite the claims process.
3. Follow the Manufacturer’s Process: Each manufacturer has specific requirements for warranty claims. Your technician may handle the process on your behalf, but it’s essential to follow all manufacturer instructions to avoid claim denial.

​By staying informed about your warranty terms and keeping thorough records, you can make the claims process smoother and avoid unnecessary delays.

Conclusion: Maximizing the Value of Your AC Warranty
