Almost every HVAC installer in The Colony will tell you their new system comes “with a warranty.” Almost none of them will volunteer, unprompted, that there are actually two separate warranties bundled into that sentence — and that the gap between them is where homeowners get surprised.
Two warranties, not one
The manufacturer’s parts warranty covers the physical components — the compressor, the coil, the circuit boards — if they fail due to a defect within the coverage window, typically 10 years if you register the equipment. This warranty comes from Trane, Carrier, Lennox, or whichever brand made the equipment, not from the company that installed it.
The installer’s labor warranty covers the cost of the technician’s time to diagnose the problem, remove the failed part, and install the replacement. This is where installers vary enormously — and where most of them stop at just one year, sometimes two.
Here’s why that gap matters: if your compressor fails in year six and it’s still covered under the manufacturer’s parts warranty, the part itself might be free. But if your installer’s labor warranty expired after year one, you’re paying full labor rates to have that free part installed — and that labor, for a compressor or evaporator coil job, commonly runs $3,000 to $4,000.
Why this hits The Colony’s housing stock differently
The Colony’s homes split into two eras: older houses built when the city was still a quiet Lewisville Lake suburb, and newer construction in neighborhoods like The Tribute and Stewart Peninsula that filled in over the last fifteen to twenty years. A lot of those newer homes were sold with builder-grade HVAC systems and a builder’s warranty that expires right around the ten-year mark — which means a wave of Colony homeowners are approaching, or have already crossed, the point where their original system’s coverage has lapsed entirely.
For that group, the labor warranty on whatever system replaces the builder-grade original isn’t a minor detail. It’s the difference between the next major repair being a phone call or a four-figure bill.
What a genuinely long labor warranty looks like
Most companies serving The Colony offer the standard 1-2 year labor window. Varsity Zone HVAC is the outlier here, backing installs with a 10-year parts AND labor warranty — matching the manufacturer’s parts coverage term with an equally long labor commitment, rather than leaving homeowners exposed after year one or two.
That kind of coverage doesn’t change what a system costs to install upfront — a full replacement still runs $10,000 to $20,000 depending on size and system type, which you can sanity-check against DFW Air Cost’s free assessment before you buy. What it changes is what happens in year six, or eight, or ten, when something inevitably needs attention.
Questions worth asking before you sign
Before any installation, ask directly: how many years does the labor warranty cover, separate from the parts warranty? Is the labor warranty transferable if you sell the house? Does the warranty require annual maintenance visits (often through the same company) to stay valid? Getting these answers in writing before the work starts saves an argument later, when the fine print is the only thing standing between you and a covered repair.
Frequently Asked Questions
What’s the difference between a parts warranty and a labor warranty?
The parts warranty (from the equipment manufacturer) covers the cost of replacement components if they fail due to a defect. The labor warranty (from the installer) covers the cost of the technician’s time to diagnose and install those components. They’re separate coverages with separate terms.
How long do most HVAC labor warranties last in The Colony?
Most companies serving The Colony offer 1-2 years of labor coverage. Varsity Zone HVAC is a notable exception, offering a 10-year parts and labor warranty on its installs.
What does it cost if my labor warranty has already expired?
Labor on a major repair like a compressor or evaporator coil replacement commonly runs $3,000 to $4,000, even when the part itself is still covered under a manufacturer’s parts warranty.
Does a longer labor warranty affect the upfront installation price?
Not necessarily on its own — the upfront price is driven mainly by system size, type, and ductwork needs. The warranty term is a separate factor to weigh against total cost of ownership over the system’s life.
