First job: register the manufacturer warranty
This is the item new owners miss most, and it has a deadline. Many manufacturers give a longer parts warranty — often ten years instead of five — only if the equipment is registered shortly after closing, commonly within about 60 days.
Miss that window and the coverage quietly shrinks to the shorter base term. Nobody sends a reminder, and you usually discover it years later, at the exact moment you file a claim.
Registration is normally free and takes the model and serial numbers from the equipment sticker plus your closing date. Do it in your first week in the house, not your first summer.
What do you need to register the warranty?
The brand, model number and serial number from the outdoor unit's sticker, your name and address, and the closing or installation date. Photograph the sticker first — once you have that photo, the online form takes only a few minutes.
What if the 60-day window already passed?
Register anyway, or confirm the status with the manufacturer. Even on the shorter base term, having the equipment recorded in your name makes any later claim faster, and you will know exactly what coverage you actually hold.
Find the model sticker before you need it
Every future repair call goes faster with one photo: the data plate on the outdoor unit. It carries the brand, model, serial number, refrigerant type and electrical ratings — the facts a pro uses to source parts before arriving.
Serial numbers usually encode the manufacture date, which tells you the system's true age. In a new build that should match the build year; in a resale purchase it sometimes holds a surprise.
Take the photo now, while the unit is clean and the light is good, and keep it with your closing paperwork. Read more about what the two warranties do and do not cover on the new-home warranty explainer.
Builder warranty basics, in plain terms
Two different warranties cover a new home's cooling, and they are not interchangeable. The builder's warranty typically covers the home's systems and workmanship for a limited early period — often the first year or two — and runs through the builder's own service process.
The manufacturer's warranty covers the equipment's parts for longer, but usually not the labour to fit them, and not parts like filters or damage from poor maintenance. Knowing which door to knock on saves weeks.
Keep both sets of paperwork, note the builder's claim deadline in your phone, and report any first-year cooling complaint in writing before that deadline passes, even if it seems minor.
First-season checks you can do yourself
Walk the house with fresh eyes. Confirm every supply vent is open and unblocked by furniture or rugs, find the filter slot, note the filter size, and replace whatever the construction dust left behind — new-build filters often come pre-loaded with drywall dust.
Outside, find the condensate drain outlet and check it drips while the system runs. Inside, learn where the unit's shut-off switch and your breaker panel are before you need either in the dark.
Set the thermostat conservatively for the first hot week and pay attention. Even cooling in every room is the baseline; a room that never matches is worth reporting while builder coverage is live.
Which room should you watch most closely?
The farthest bedroom from the indoor unit, especially an upstairs room over the garage if you have one. Distance and heat gain expose weak airflow and duct problems there first, while the rest of the house still feels acceptable.
Should a brand-new system get a tune-up?
A light first-year check is a reasonable spend: filter and drain confirmed, connections and charge verified, and a baseline recorded for later years. It also creates a maintenance record, which some warranty claims ask about. See what a seasonal tune-up visit covers.
What the first summer usually reveals
Even well-built homes show teething problems in their first real heat. One room runs warm because a damper was left set for winter construction. A drain line installed at a shallow angle drains slowly and gurgles. The system cools, but runs longer than neighbours' systems do.
Document these while they happen — dates, thermostat readings, which rooms — rather than relying on memory at a warranty appointment in October. Specifics get faults found; impressions get 'it seems fine today'.
Most first-summer faults are adjustments, not failures, and they are exactly what builder coverage exists for. Reported early, they cost you a phone call. Found in year three, they cost you a repair bill — the kind priced out in the typical Cibolo repair ranges.
The 8 to 12 year outlook for builder systems
Plan ahead with clear eyes. Roughly three quarters of homes in ZIP 78108 were built between 2000 and 2019, and homes built in the 2010–2022 stretch commonly meet their first major AC failure at eight to twelve years — capacitors, contactors and drain faults first.
That does not make your system a bad one. It means the smart move is budgeting and maintenance, not surprise: keep filters and drains on schedule, and know the new-system replacement ranges early enough that a big decision never has to be rushed.
The full pattern — why volume builders fit what they fit, and which parts go first — is laid out in the guide to early failures in newer Cibolo homes.

When does the manufacturer warranty registration window start?
Usually at closing or installation, and the window to earn the longer registered term is commonly around 60 days — check your equipment brand's terms, because they vary. Because the date that matters is the closing date on your paperwork, registering in the first week in the house is the safe habit, whatever the exact deadline turns out to be.
Does the builder warranty cover a full AC replacement?
Rarely in practice. Builder coverage focuses on defects in installation and workmanship during its term, while the manufacturer covers failed parts on the equipment itself. A complete system failure in the first years usually lands as a manufacturer parts claim plus labour costs, which is why knowing both warranties — and their deadlines — matters from day one.
What if we bought a resale home, not a new build?
Most of this checklist still applies. Find the model sticker, work out the system's age from the serial number, and ask the seller for any transferable warranty paperwork, since some manufacturer coverage transfers to a new owner if it is registered properly. Then run the same first-season checks: filter, drains, vents, and how evenly the rooms cool during the first serious heat.
The upstairs is warmer than downstairs. Is that a warranty issue?
Possibly. A modest difference is normal in two-story Texas homes, but a large, persistent gap in a brand-new home can mean a duct, damper or airflow fault that builder coverage should look at. Write down the actual temperatures in both zones on a hot afternoon before you call. Measured numbers turn a vague complaint into a fault a builder's contractor can chase.
Should I buy a home warranty for the AC?
That is a budgeting choice, not a requirement. Read any plan's fine print on pre-existing conditions, payout caps and who chooses the contractor before deciding, because coverage quality varies a lot. Either way, it does not replace registering the manufacturer warranty — that step is free, takes minutes, and protects the most valuable coverage you already own.
