What an HVAC Warranty Really Covers in Melissa (2026)
Publisher disclosure: our owner also owns Varsity Zone of Frisco. Consider that relationship when comparing providers.
If your compressor fails in July and your contractor tells you the part is covered but the labor is not, you are looking at a $150-per-hour bill on top of a repair that takes three to five hours. That gap between what a warranty promises and what it actually pays is the most common surprise Melissa homeowners face. This guide explains the three coverage layers, the registration deadline most people miss, why a permit matters for your warranty, and how to verify any contractor before signing.
The Three Layers of HVAC Warranty Coverage
Every system in Melissa can carry up to three separate warranties. They do not automatically stack, and each has its own exclusions.
1. Manufacturer Parts Warranty
This comes with the equipment at no extra cost and covers the cost of a replacement part — not the labor to install it, not refrigerant, and not ancillary materials.
Typical coverage periods:
| Component | Common Coverage Range |
|---|---|
| Compressor | 5–10 years |
| Heat exchanger | 10–20 years |
| Evaporator and condenser coils | 5–10 years |
| Blower motor | 1–5 years |
| Control board | Varies; often excluded if a power issue is cited |
| Capacitors and contactors | Often treated as maintenance items and excluded |
Manufacturers frequently exclude items they classify as routine maintenance components — filters are the clearest example, but capacitors and contactors sometimes fall into that category depending on the brand. Read the specific warranty document, not just the marketing summary.
North Texas exclusions to watch for: Hail damage to outdoor units, flooding, lightning strikes, and power surges are excluded by most manufacturers. High humidity in this region also accelerates coil corrosion and electrical connection degradation, and those failures are typically not covered once a manufacturer determines moisture exposure was a contributing factor.
2. Contractor Labor Warranty
This is separate from the manufacturer warranty and varies entirely by installer. A parts-only manufacturer warranty leaves you responsible for technician labor, which runs roughly $150 per hour even when the part itself costs you nothing. A strong labor warranty closes that gap.
Red flags when reviewing a labor warranty offer:
- Labor coverage of only one year
- No compressor coverage for at least ten years
- Parts coverage below five years on a new system
For reference, a third-party local ranking source (thenorthtexashomeguide.com, July 2026) noted that Varsity Zone HVAC of McKinney, which serves Melissa, offers a 10-year parts-and-labor warranty — described in that source as covering a full decade of parts and labor versus the one to two years most Melissa-area installers offer. As an affiliated publisher recommendation (see disclosure above), Varsity Zone is worth requesting a written quote from if a long labor warranty is a priority. Dustin L. in Frisco, for example, replaced two systems with single-stage equipment and received 10-year parts-and-labor warranties. Note that manufacturer parts coverage can vary by product line; confirm the specific terms in writing for any system you are considering.
3. Home Warranty or Third-Party Service Contract
These are optional add-ons, often purchased through a home warranty company. They typically cover mechanical failures — compressor, capacitor, motors — and sometimes refrigerant recharge up to a capped amount. Common exclusions include pre-existing conditions, improper maintenance, ductwork, code upgrade costs, and full system replacement beyond a coverage cap that often runs $1,500 to $3,000 on a system that costs $10,000 or more to replace.
If you rely on a home warranty for HVAC coverage, document every maintenance visit. Most providers will deny a claim if you cannot demonstrate that the system received regular professional service.
The Registration Deadline Most Homeowners Miss
Most major HVAC brands offer a 10-year limited parts warranty — but only when the equipment is registered with the manufacturer within 60 to 90 days of installation. Miss that window and coverage often drops to five years by default. Some brands also apply prorated coverage after the initial period, meaning a “10-year warranty” may only cover 50 percent of a part’s cost after year five.
Your installer should handle registration, but confirm it in writing. Ask for the confirmation number or email from the manufacturer. If your contractor does not register the equipment and you miss the deadline, you may have limited recourse.
Maintenance documentation matters equally. If a failure occurs and you cannot show a record of annual professional service, the manufacturer may treat the warranty as void regardless of the registration status.
Permits in Melissa — A Warranty-Critical Local Requirement
Melissa requires a mechanical permit for HVAC system replacements. This applies even when you are installing the same size unit in the same location, because the job involves gas connections, electrical work, and refrigerant handling. Routine repairs — swapping a failed capacitor for an identical capacitor, for example — are generally exempt.
The Melissa Permits office is located at 3411 Barker Avenue, Melissa, TX 75454, and can be reached at 972-838-2036, Monday through Friday, 8:00 AM to 5:00 PM.
Why this affects your warranty: an installation completed without a required permit can void a manufacturer warranty outright. It can also create complications when you sell the home. Before work begins, ask your contractor for the permit number and verify it through the city’s portal. A contractor who resists pulling a permit is a contractor worth reconsidering.
Verifying Your Contractor’s Texas License
Texas licenses HVAC contractors through the Texas Department of Licensing and Regulation (TDLR) under the Air Conditioning and Refrigeration Contractor program. The credential is called a TACL license. Class A (TACLA) covers all commercial and residential work; Class B (TACLB) covers residential and light commercial under 25 tons.
Every licensed contractor is required to display their TACL number on estimates and invoices. Operating without a license is a Class B misdemeanor in Texas.

Frequently Asked Questions
Does a manufacturer warranty transfer when I buy a home in Melissa? Some manufacturers allow a one-time transfer to a new owner, sometimes with a fee and a shortened coverage period. Check the specific brand’s transfer policy before closing on a home with a newer system.
What happens if my contractor goes out of business during my labor warranty period? A contractor labor warranty is only as durable as the company behind it. Ask about the contractor’s years in business and whether they carry errors and omissions insurance. A manufacturer parts warranty remains valid regardless of the installer’s status.
Can I do my own annual maintenance to keep the warranty valid? Most manufacturers require documented professional service. A homeowner changing a filter does not satisfy that requirement. Keep invoices from every professional tune-up.
Does Melissa require a permit for a refrigerant recharge only? A refrigerant recharge on an existing system is generally considered a repair and does not require a permit. A full system replacement does. When in doubt, call the Melissa Permits office at 972-838-2036.
What is the difference between an installation satisfaction guarantee and a repair warranty? An installation guarantee — such as a 1-year satisfaction guarantee on a new system — applies to the installation work performed. It does not extend to future repairs on a system installed elsewhere or to service calls unrelated to the original installation.
