TL;DR: A ten-year parts warranty pays for a replacement part when a covered component fails because of a factory defect. It does not pay for labor, diagnosis, storm or surge damage, or failures caused by poor installation or neglect. Many brands only give the full 10 years if you register the system on time.
A ten-year parts warranty pays for a replacement part when a covered component fails because of a factory defect in the first 10 years. It does not pay a technician’s labor to find and replace that part. It also won’t cover damage from lightning, floods, or a bad installation. Many brands only give you the full 10 years if you register the system.
This guide explains the ten-year parts warranty in plain terms for homeowners in Tavares and nearby towns like Zellwood and Astor. Long cooling seasons and summer storms here put a lot of hours and stress on equipment.
What does a ten-year parts warranty actually cover?
It covers parts that fail because of a defect in materials or workmanship from the factory. That usually means the compressor, coils, fan motors, and control boards. If a motor dies in year six because it was built wrong, the manufacturer supplies a new one at no charge.
The key word is limited. Carrier’s published warranty for its AC and heat pump condensing units excludes labor and other costs for diagnosing, repairing, removing, or installing parts. The same document says the product has to be installed correctly by a licensed HVAC technician and has to stay where it was first installed. American Standard’s registered warranty works the same basic way: it pays for defective parts, not the labor to replace them.
Ten years covers a large part of a system’s working life, but not all of it. Our guide on how long an AC unit lasts in Florida explains what wears equipment out faster in our climate.
Who pays for what when a part fails?
The manufacturer pays for the part. Depending on the cause and the timing, the rest falls to you, your installer’s labor coverage, or your insurance.
| Cost | Ten-year parts warranty | Installer’s labor coverage | Who usually pays |
|---|---|---|---|
| Defective part (motor, coil, board) | Covered if registered and still in term | Not a parts issue | Manufacturer |
| Labor to diagnose and replace the part | Not covered | Covered during the guarantee period, per its terms | Homeowner, once labor coverage ends |
| Lightning, flood, or wind damage | Excluded | Not covered | Homeowner’s insurance, depending on the policy |
| Routine upkeep (filters, coil cleaning) | Excluded | Not covered | Homeowner |
| Failure caused by poor installation | Excluded | Installer’s workmanship coverage, per its terms | Installing contractor |
So a part covered under warranty can still come with a bill. A compressor swap means recovering refrigerant, brazing, evacuating the system, and recharging it. The manufacturer’s warranty does not pay for those hours.
Do you have to register your AC to get the full 10 years?
With many brands, yes. Carrier’s warranty documents say the longer term applies only if the equipment is registered within 90 days. Otherwise you get 5 years. The exceptions are places like California and Quebec, where registration can’t be made a condition. Don’t count on an exception covering you. Register within the deadline.
These situations catch people off guard:
- Snowbirds: If your system gets replaced in spring before you head north, register it before you leave. The clock keeps running while you’re gone.
- New construction: On a new home, Carrier counts the date the original owner bought the house from the builder as the installation date. If you bought a new home near Tavares, make sure the builder’s equipment is registered in your name.
- Rental properties: Carrier’s ductless warranty lists a shorter term for applications other than the standard residential one. Landlords should read that section closely.
- Home buyers: Some longer terms only cover the original owner. Before closing, ask what transfers to you.
Keep one folder with the model and serial numbers, the install date, the permit, and your registration confirmation.
What gets a warranty claim denied in Central Florida?
Most denials come from outside damage or from installation and service mistakes. Carrier’s ductless warranty, for example, excludes failures from floods, winds, fires, lightning, and corrosive environments. It also excludes voltage problems and faulty installation.
That matters here. The Florida Division of Emergency Management calls Florida the Lightning Capital of the United States. If a summer storm in Grand Island sends a surge that fries a control board, the warranty excludes it, and your homeowner’s policy may or may not pay. Homes near the St. Johns River around Astor have the same problem when flood water reaches the outdoor unit.
Maintenance matters too. Filter changes and coil cleaning are the owner’s job, and failures caused by neglect aren’t factory defects. A clogged filter is one of the easiest problems to avoid. Our guide to choosing an AC filter by MERV rating can help you pick the right one.
One common myth: federal law protects your right to choose your service company. The Federal Trade Commission explains that a warrantor generally can’t require a specific company’s service to keep your coverage, unless it provides that service free. It can still deny a claim for damage that outside work actually caused. So the company that does your tune-up won’t void the warranty, but bad work can still cost you a claim.
Is a parts-only warranty good enough?
For defects in major components, it gives solid protection. The gaps are labor and outside damage.
Pros:
- Covers expensive components like the compressor and coils for up to a decade.
- Comes with the equipment when it’s registered correctly.
- Stays with the equipment, not with one service company.
Cons:
- You pay for labor, diagnosis, and trip charges once the installer’s labor coverage ends.
- Storm, surge, and flood damage are excluded, and all three are common risks in Central Florida.
- A missed registration can cut coverage short.
- Coverage may not fully transfer to the next owner.
For most homeowners, the gap that matters is labor in years two through ten. Ask any installer to put in writing how long their labor coverage lasts and what it includes. If your system starts acting up, for example blowing warm air, get it checked early while the part is still covered.

Frequently Asked Questions
How do I check whether my AC was registered for the full warranty?
Get the model and serial numbers from the data plate on your outdoor unit. Then use the warranty lookup or registration page on the manufacturer’s website. Save the confirmation email as proof of the date you registered.
If my compressor fails, does the parts warranty replace the whole unit?
Usually not. A parts warranty covers the failed part, not a new system. Some brands offer a separate unit replacement warranty with strict conditions. Carrier’s, for example, requires an outdoor unit paired with a matching indoor coil that is listed in the AHRI directory.
Is the ten-year warranty from the manufacturer or the installer?
The parts warranty comes from the equipment manufacturer, and labor coverage comes from the installing contractor. On Lucas Air Conditioning and Heating installations, both a ten-year parts warranty and a one-year labor guarantee are included.
Can moving my outdoor unit affect the warranty?
It can. Carrier’s condensing unit warranty, for example, only applies to products that stay in their original installation location. Before you relocate equipment, read your warranty terms.
