Most homeowners file a new HVAC warranty in a drawer and forget about it. Then the compressor dies six years later, and the fine print becomes the most important thing they’ve never read. An HVAC warranty is part of every new system installation, and understanding what it actually covers before something breaks can save you a lot of money and frustration.
This guide breaks down exactly what your HVAC warranty covers, what it doesn’t, and what can quietly cancel your coverage without you realizing it. If you’re an Atlanta homeowner with a newer system or shopping for a replacement, this is the article to read first.
There’s More Than One Warranty on Your HVAC System
This surprises a lot of homeowners. When a new system goes in, you actually get several overlapping (and very different) warranties. Knowing which is which matters when something breaks.
The Manufacturer’s Parts Warranty
This is the warranty that comes directly from the brand, covering Carrier, Trane, Lennox, Goodman, and others. It covers defective parts, meaning components that fail because of how they were made, not because of how they were used or maintained.
Most manufacturers cover standard internal parts for five to ten years. The compressor, which is the most expensive component in your AC system, often gets a longer warranty, sometimes up to ten or twelve years. The heat exchanger on a furnace can carry coverage even longer, sometimes up to a lifetime on higher-end models.
Here’s what the manufacturer’s parts warranty does not cover: labor. If a covered part fails and needs to be replaced, the manufacturer provides the part, but you pay a technician to install it. That labor cost can be substantial, which is why the next warranty matters.
The Labor Warranty
Labor warranties are offered by the installing contractor, not the manufacturer. They typically cover one to five years and protect you against the cost of labor if something goes wrong with the installation or if covered repairs are needed within that period.
Not every contractor offers a labor warranty, and the terms vary widely. Always ask what labor coverage is included before signing any installation contract. It’s a good question to raise whether you’re looking at AC installation or furnace installation.
Extended Warranties
Extended warranties are optional add-ons you can purchase through your dealer at the time of installation. They can extend parts coverage beyond the manufacturer’s standard period, and many include labor coverage as well, which makes them a meaningful upgrade over the base warranty. Coverage can typically be purchased in five, ten, or twelve-year increments depending on the manufacturer and dealer.
Extended warranties are worth evaluating carefully. For a system that will run hard through Atlanta summers for the next fifteen or more years, the math often works in the homeowner’s favor.
Home Warranties (Not the Same Thing)
A home warranty is a separate annual service contract, often purchased by homeowners or included in a real estate transaction, that covers a range of home systems and appliances. It is not the same as the manufacturer’s warranty, and the two should not be confused.
Home warranties can cover HVAC repairs, but with significant limitations. Many cap HVAC payouts at $1,500 per contract term, according to reporting by U.S. News Real Estate. Coverage caps, exclusions for pre-existing conditions, and requirements to use the warranty company’s own contractors make these plans more complicated than they appear. They can be worthwhile for some homeowners, but read the contract carefully before relying on one for HVAC coverage.
What a Manufacturer’s Warranty Typically Covers
Every brand is different, but most standard manufacturer warranties cover the following when a part fails due to a manufacturing defect:
- Compressor
- Heat exchanger
- Evaporator and condenser coils
- Circuit boards and electrical components
- Blower motors and fan motors
- Reversing valves (on heat pumps)
- Other internal mechanical parts specified in the warranty document
“Manufacturing defect” is the key phrase. The warranty covers parts that failed because of how they were built. It does not cover parts that failed because of how the system was used, maintained, or installed.
What’s Not Covered (This Is the Part Most Homeowners Miss)
The exclusions are where most warranty surprises live. Here’s what is typically left out of a standard manufacturer’s warranty:
Labor costs. As noted above, parts warranties almost never include labor. When a covered part fails, you’ll still pay a technician to do the work unless you have a labor warranty or extended plan.
Refrigerant. Refrigerant leaks and recharges are frequently excluded from manufacturer warranties. Some extended plans or home warranty upgrades include refrigerant coverage, but you should confirm this specifically before assuming it’s included.
Routine maintenance items. Filters, belts, capacitors in some cases, and other components that are expected to be replaced through normal maintenance are often excluded. Check the specific exclusions listed in your warranty paperwork.
Ductwork. Most manufacturer warranties cover the unit itself, not the duct system connected to it. Ductwork issues are a separate repair cost.
Damage from improper installation. If the system was installed incorrectly, whether by an unlicensed contractor or through improper sizing or setup, manufacturers are not responsible for the resulting damage. This is one of the most commonly cited reasons for denied claims.
Damage from lack of maintenance. Neglected systems lose warranty protection. If a failure is linked to dirty coils, a clogged drain line, or a filter that was never changed, the manufacturer can and often will deny the claim.
Storm damage, flooding, power surges, and acts of nature. These are homeowner’s insurance events, not warranty events. Lightning strikes, flooding, and electrical surges are typically excluded from all manufacturer warranties.
Pest damage. Rodents chewing through wiring or insulation is not covered. It’s more common than homeowners expect, particularly in attic and crawl space installations.
Cosmetic damage. Rust on the cabinet, dents, fading, and similar surface issues don’t affect function and aren’t covered.
The Registration Deadline Most Homeowners Miss
This is one of the most important and most overlooked aspects of any HVAC warranty. Many manufacturers, including Trane, require product registration within 60 days of installation to unlock the full extended warranty term.
Here’s how it works in practice, using Trane as an example. If you register within 60 days, you receive the Registered Limited Warranty, which typically covers parts for ten years. If you miss that window, your system defaults to the Base Limited Warranty, which typically covers parts for only five years, at no additional charge but with half the coverage period. According to Trane’s warranty documentation, registration must be completed within 60 days of installation to qualify for extended coverage.
Other manufacturers have similar requirements, with registration windows that can range from 30 to 90 days depending on the brand.
Ask your contractor whether they handle registration on your behalf at the time of installation. Many reputable HVAC companies do this as part of their installation process. If you had a system installed elsewhere, check your paperwork now and verify registration status directly with the manufacturer using your model and serial number.
What Voids an HVAC Warranty
This is the section worth reading twice. Any one of these can cancel your coverage, often permanently.
Installation by an unlicensed contractor. Manufacturers require systems to be installed by a licensed HVAC professional. Using an unlicensed contractor or handyman, even one who does the job correctly, can void the warranty entirely. According to ACCA (Air Conditioning Contractors of America), manufacturer warranties consistently require licensed professional installation as a condition of coverage. Most homeowners don’t learn about this restriction until they file a claim and read the fine print.
DIY repairs. Attempting to repair your own system, even minor work, can void warranty coverage. Manufacturers require that all service be performed by qualified technicians.
Using non-OEM (off-brand) replacement parts. If a repair is done using parts not supplied or approved by the original manufacturer, the warranty on that system is typically voided. This is a risk when using the lowest-cost repair option available.
Skipping maintenance. Many manufacturer warranties explicitly require regular maintenance and can be voided if a failure is linked to documented neglect. If you ever file a claim, the manufacturer may ask for proof of maintenance history. Without service records, the claim can be denied even if the part is technically under warranty.
Modifying or bypassing safety devices. Changing electrical components, bypassing safety switches, or other modifications to the system can void coverage immediately.
Rental properties (in some cases). Some manufacturer warranties are written for owner-occupied residential use only. If your property is a rental, confirm that your warranty terms apply before assuming coverage.
Why Maintenance Records Matter More Than Most Homeowners Realize
This point deserves its own section because it catches so many homeowners off guard. A warranty isn’t a set-it-and-forget-it protection. Most manufacturer warranties require documented, regular maintenance to remain fully valid.
If a compressor fails in year seven and you file a warranty claim, the manufacturer may request your service history. If you can’t produce records showing the system was properly maintained, the claim can be denied, even if the compressor itself is clearly defective.
Practical ways to protect yourself:
- Schedule annual tune-ups with a licensed HVAC contractor and keep the service receipts
- Keep a folder (physical or digital) with your warranty certificate, registration confirmation, installation paperwork, and every service visit record
- If you move into a home with an existing HVAC system, ask the seller for the warranty documents and any service history before closing

Warranty Transfers: What Happens When You Buy or Sell a Home
HVAC warranties are typically attached to the equipment, not the homeowner. Most major brands allow the warranty to transfer to a new homeowner when a home is sold, but the process has rules and deadlines.
For Trane, the warranty transfer must be completed within 90 days of the home sale, and either the seller or the new homeowner can initiate it. Trane charges a $99 transfer fee, and the new owner inherits whatever time remains on the original registered warranty term. For Carrier, the new homeowner must register the equipment within 90 days of the home purchase. With Carrier, subsequent owners typically receive a five-year parts warranty rather than the original owner’s longer registered term. Miss the transfer window entirely, and the new owner may lose the remaining coverage.
If you’re buying a home:
- Ask the seller for all HVAC warranty documents before closing
- Confirm the system is registered and under warranty by looking up the serial number on the manufacturer’s website
- Initiate the warranty transfer within the required window after closing
If you’re selling a home, having a current service history and documented warranty coverage on your HVAC system is a genuine selling point and worth maintaining through the sale process.
Manufacturer’s Warranty vs. Home Warranty: Key Differences at a Glance
| Manufacturer’s Warranty | Home Warranty | |
| What it covers | Defective parts from the manufacturer | Breakdowns from normal wear and tear |
| Who provides it | Equipment manufacturer | Third-party service company |
| Labor included | Usually no | Usually yes, up to a cap |
| Cost to you | Included with equipment | Annual premium plus service fee per visit |
| Contractor choice | Your licensed HVAC contractor | Company’s assigned contractor |
| Coverage limits | Varies by part and product | Often $1,500 per system per term |
Neither replaces the other. The manufacturer’s warranty protects against defective equipment. A home warranty, if the terms are right, can help with unexpected repair costs. Knowing which applies to your situation, and what each requires of you, is what keeps a claim from being denied.
Frequently Asked Questions
In most cases, a standard manufacturer’s warranty covers parts only, not labor. Labor costs to install a covered part come out of pocket unless you purchased an extended warranty that includes labor coverage or your installing contractor provided a separate labor warranty. Always ask specifically about labor coverage before signing.
Missing the manufacturer’s registration window typically reduces your coverage period significantly. With Trane, failing to register within 60 days drops coverage from ten years to five years. Other brands have similar requirements. Confirm your system is registered by checking with the manufacturer using your serial number.
Most manufacturers require that service and repairs be performed by a licensed HVAC professional. Using an unlicensed contractor or attempting DIY repairs can void your warranty, even if the repair itself is done correctly. For repairs in the Atlanta area, contact Berry Good Heating & Air to keep your warranty intact.
It can. Many manufacturer warranties require documented, regular maintenance and reserve the right to deny claims if a failure is linked to neglect. A single missed tune-up may not automatically void a warranty, but a pattern of undocumented or absent maintenance can give a manufacturer grounds to deny a claim. Keep your service records.
Typically, no. Standard manufacturer warranties usually exclude refrigerant. Some extended warranty plans and select home warranty tiers include refrigerant coverage, but you should confirm this in writing before assuming it’s included.
A manufacturer’s warranty comes from the equipment brand and covers defects in how the system was made. A home warranty is an annual service contract, usually from a third-party company, that covers breakdowns from normal wear and tear across multiple home systems. They operate very differently and are not interchangeable.
Most major manufacturers allow warranty transfers, but the process has deadlines and fees. With Trane, the transfer must be completed within 90 days of the home sale and a $99 fee applies. With Carrier, the new homeowner must register within 90 days, though subsequent owners typically receive only a five-year parts warranty rather than the original extended term. Miss the window, and the new owner may lose the remaining coverage entirely.
The most common ways to void a warranty include: having the system installed or repaired by an unlicensed contractor, failing to register the equipment within the required window, using non-OEM replacement parts, neglecting documented maintenance, and making unauthorized modifications to the system.
