What a 10-Year HVAC Warranty Really Covers in McKinney (2026)
Publisher disclosure: our owner also owns Varsity Zone of Frisco. Consider that relationship when comparing providers.
When a McKinney contractor advertises a “10-year warranty,” that phrase can mean very different things depending on what is actually in the paperwork. This guide breaks down the two separate warranties involved in every new installation, what each one excludes, and the specific rules that can quietly reduce or eliminate your coverage.
The Two Warranties in Every New Installation
1. Manufacturer Parts Warranty
Major brands — Carrier, Trane, Lennox, Goodman, American Standard — offer a Registered Limited Warranty of up to 10 years on parts. To get that full term, you must register the equipment with the manufacturer within 60–90 days of installation. If you miss that window, coverage automatically drops to the Base Limited Warranty, typically five years.
What parts warranties generally cover:
- Compressor (5–10 years depending on brand)
- Heat exchanger (10–20 years)
- Other functional components (1–5 years)
What parts warranties generally exclude:
- Labor — technician rates in McKinney run roughly $150/hour, and that cost falls on you even when the defective part itself is free
- Refrigerant
- Power surge damage
Some warranties are also prorated, meaning coverage after year five may reimburse only a percentage of the part’s value, not the full replacement cost.
2. Contractor Labor Warranty
This is the warranty most homeowners overlook. The installing contractor’s labor warranty is a separate document from the manufacturer’s parts warranty, and the two do not automatically align. Most residential HVAC contractors in Texas offer one to two years of labor coverage. A 10-year labor warranty from the contractor is less common and worth asking about specifically before you sign.
What Can Void Your Coverage
| Risk | What Happens |
|---|---|
| Missing registration deadline | 10-year parts warranty reverts to 5 years |
| No annual maintenance records | Manufacturer can deny claims |
| Unlicensed contractor performed the work | Equipment warranty may be voided entirely |
| No permit pulled in McKinney | Creates legally ambiguous installation record |
| Prorated terms buried in fine print | ”10-year” coverage pays less after year 5 |
Annual maintenance documentation is a requirement most homeowners do not realize is enforceable. Manufacturers can deny a repair claim if you cannot show professional service records for each year the system was in operation. Missing a single year’s tune-up can cost you $1,500–$4,500 in out-of-pocket repair costs on a part that should have been covered.
Texas Law and Federal Protections
Magnuson-Moss Warranty Act (15 U.S.C. §2301): Federal law requires manufacturers to make warranty terms available before purchase. It also bars a manufacturer from voiding your coverage solely because a different licensed shop performed maintenance or a repair — so you are not locked into using the original installer for every future service call.
Extended service contracts: If a contractor offers coverage beyond the standard manufacturer warranty as a purchased add-on, that product is regulated under Texas Occupations Code §1304 and must be offered through a licensed provider.
Warranty transferability (Texas HB 2110): For systems purchased, installed, and registered after 2021, the manufacturer’s warranty transfers to a new homeowner without a fee and without a reduction in the remaining term. Under the prior rule, a new owner received only half of the original registered warranty.
McKinney Permit Requirements
The City of McKinney requires a permit for HVAC replacements. These are processed as over-the-counter (OTC) permits through McKinney’s Building Inspections Department, and residential mechanical permit fees run approximately $40 — lower than many neighboring cities. A passed city inspection creates a documented record that the installation met code, which matters in warranty disputes where a manufacturer or contractor claims the other party caused a failure.
McKinney permits its own territory independently from Collin County. If you are near a jurisdiction boundary, confirm which entity governs your address before assuming county rules apply.
How to Verify Any McKinney Contractor
Texas requires HVAC contractors to hold a license issued by the Texas Department of Licensing and Regulation (TDLR). For residential work, the relevant license is a Class B ACR Contractor License (systems under 25 tons). Technicians handling refrigerant must also hold EPA Section 608 Certification.
Verify any contractor’s current license status at tdlr.texas.gov/LicenseSearch. License expiration dates change; always check before signing a contract.

Frequently Asked Questions
Q: If I forget to register my equipment, is the warranty gone entirely? No, but it drops from 10 years to the base term — typically five years for most major brands. Register within 60–90 days of installation and keep the confirmation.
Q: Can a manufacturer void my warranty because I used a different company for my annual tune-up? Federal law (Magnuson-Moss, 15 U.S.C. §2302(c)) bars manufacturers from voiding coverage solely because a different licensed shop performed maintenance. However, you still need documented proof that annual professional service occurred.
Q: Does my warranty transfer if I sell my McKinney home? For systems installed and registered after 2021, Texas HB 2110 requires the manufacturer’s warranty to transfer to the new owner without a fee and without a reduction in the remaining term.
Q: What is the difference between a parts warranty and a labor warranty? A parts warranty means the manufacturer replaces a defective component at no parts cost. A labor warranty means the contractor covers the technician’s time to diagnose and install that part. Without a labor warranty, you pay hourly labor rates — roughly $150/hour in McKinney — even when the part itself is free.
Q: Do I need a permit for an HVAC replacement in McKinney? Yes. McKinney requires a permit for HVAC replacements, processed as an over-the-counter permit through the city’s Building Inspections Department. The fee is approximately $40. A passed inspection creates a code-compliance record that can be consequential in warranty disputes.
