What Voids an AC Warranty in Texas? (What Homeowners Need to Know)
A new AC system in Texas comes with a 10-year parts warranty — but only if you meet specific conditions. Many Spring TX homeowners unknowingly void their warranty before the system is a year old. Here's what protects it and what voids it.
The 10-year warranty on a Carrier or Trane AC system isn't automatic. It requires equipment registration within 90 days of installation, licensed contractor installation, and in some cases ongoing maintenance documentation. Failing any of these can reduce your warranty to 5 years — or void it entirely for specific claims.

Things That Void or Reduce Your AC Warranty
Not registering within 90 days: Most manufacturers require registration within 90 days of installation. Without registration, the warranty typically drops from 10 years to 5 years. The installing contractor is responsible for registration — confirm it happened.
Installation by an unlicensed contractor: Manufacturer warranties require installation by a licensed HVAC contractor. In Texas, that means a TDLR-licensed Air Conditioning and Refrigeration contractor. Unlicensed work voids the warranty entirely.
Using mismatched or non-AHRI certified components: Installing an outdoor unit with a non-AHRI-certified indoor coil can void the manufacturer's efficiency warranty and may affect parts warranty coverage.
Adding wrong refrigerant: Adding an incompatible refrigerant type to the system voids warranty on refrigerant system components.
Physical damage: Damage from floods, hail, fire, or improper modification is not covered under standard warranty.
What Doesn't Void Your Warranty
Normal wear and tear repairs by licensed contractors
Filter changes and minor maintenance
Thermostat replacement
Service by a different licensed contractor than the original installer

Frequently Asked Questions
What voids an AC warranty in Texas?
Common warranty voiders: failing to register the equipment within 90 days (reduces 10-year to 5-year warranty), installation by an unlicensed contractor (voids entire warranty), using mismatched non-AHRI-certified components, adding wrong refrigerant type, or physical damage from external causes. Always confirm your contractor registered your equipment after installation.
How do I register my new AC warranty in Texas?
The installing contractor is typically responsible for warranty registration with the manufacturer (Carrier, Trane, etc.) within 90 days of installation. Ask your contractor for confirmation that registration was completed, including the registration confirmation number. You can also register directly on the manufacturer's website using the model and serial numbers from the data plate.
Does skipping AC maintenance void the warranty?
Manufacturers recommend annual maintenance but routine maintenance skipping typically doesn't void parts warranty coverage for component failures. However, some extended warranty programs require documented maintenance. More importantly, skipping maintenance allows problems to develop that may damage components in ways not covered under warranty.
Is the AC warranty transferable to a new homeowner in Texas?
Most Carrier and Trane warranties are transferable to subsequent homeowners for the remaining warranty term — but this typically requires a transfer registration. The process varies by manufacturer. If you're buying a home with a newer HVAC system, verify the warranty status and transfer requirements.
