Get your free estimateThe Cold Harbour Heating and Air Houston Guarantee
Every repair we make in Houston carries a written guarantee that stays valid for 365 days from the day our technician packs up and leaves. That means if the same problem comes back within a full year, we return and correct the work at no charge. No fine print, no prorated nonsense, no arguing over whether the repair “counts.” The guarantee is printed on paper and handed to you before we leave the driveway. That’s the Cold Harbour standard, and it has been since 2003. We don’t ask you to trust a handshake when the Houston summer is about to test an air conditioner harder than any other season in the country.
What’s Covered
- The workmanship. Every repair we perform, from a capacitor swap to a full condenser fan motor replacement, is covered by our 365-Day Done Right Promise. If the repair fails in that window, the return visit and the correction cost you nothing.
- The parts we install. When we put a part in your system, we stand behind it. If a part we installed fails during the guarantee period, we replace it and redo the labor at no charge. You don’t pay twice because a component didn’t hold up.
- The price you were quoted. The written price you receive before work begins is the price you pay when the work is done. It does not change at the door, after the diagnostic, or halfway through the job. That’s not a promotion; that’s how we operate on every single call.
- The arrival window. When we give you a time, we show up in that window. If something beyond our control delays us, a live person calls you to tell you what’s happening. You’re never left wondering where the truck is.
- The cleanup. We leave your home the way we found it, or cleaner. No condensate drips on the hallway floor, no wire clippings in the grass, no oily handprints on the closet door. The Kingswell Way includes leaving the place cleaner than found, and we take that literally.
- The diagnosis. If we misdiagnose a problem and the repair doesn’t solve it, the guarantee applies. We come back, find the real issue, and make it right without billing you for the second visit.

Our Satisfaction Promise
If a Houston homeowner isn’t satisfied with a repair we made, the process is straightforward: call us, tell us what’s wrong, and we schedule the return visit. You won’t be routed through a voicemail tree or told to “leave a message and someone will get back to you.” A live person answers the phone 24 hours a day, every day of the year, and that person can dispatch a technician. When we arrive, we re-diagnose the system, review the original repair, and determine what went wrong. If the issue falls under our written guarantee, the fix costs you nothing. If it turns out to be a different problem entirely, we’ll show you what we found, explain it in plain English, and hand you a written price before any new work starts. Either way, you know exactly where you stand before a tool comes out. That second visit is free when the repair is covered by our guarantee, and it’s handled without the homeowner having to fight for it. Victor Mancini, our owner, works service calls himself, so when a guarantee issue comes up, it gets attention from the top on day one.
Licensed & Insured Backing
A warranty is only as good as the company standing behind it. Cold Harbour Heating and Air Houston is licensed and insured, and that matters more than most homeowners realize. Licensing means our technicians have met the state’s requirements to work on residential HVAC systems in Texas, which means the person in your attic or at your condenser has passed background checks, wears a Cold Harbour uniform, and answers to a real company with a Houston address. Insurance protects you if something goes wrong on the job, property damage or otherwise. The paperwork you get from us, the written price, the written guarantee, is only meaningful because a licensed and insured operator is accountable to the state and to you. If a fly-by-night outfit hands you a “guarantee,” it’s worth about as much as the napkin it’s written on. Ours has weight behind it because Cold Harbour has been operating in Houston since 2003, longer than most of the houses we service have had their current HVAC systems.

AfterWhat the Guarantee Covers in Plain Terms
Here’s the honest version of what we promise. We say the price before the work. We show up in the window we gave you. We leave the place cleaner than we found it. We put the guarantee in writing. And if the repair fails within 365 days, we come back and fix it at no charge. Those five commitments come from The Kingswell Way, the written standards that every independently owned and operated business in the Kingswell network follows. Cold Harbour is part of that network, but we’re our own company, run by Victor Mancini, and we answer to Houston homeowners directly.
The name Cold Harbour comes from the roadside shelters where travelers waited out bad weather before continuing on. That’s the job we’re hired to do in Houston: give you a place where the heat and humidity can’t reach you, no matter what the season throws at us. A guarantee that puts that comfort at risk isn’t worth the paper it’s printed on, so we don’t play games with ours.
Writer Notes on the Cold Harbour 365-Day Done Right Promise
One thing worth saying clearly, because Houston AC repair customers ask us this all the time: the guarantee is not conditional on you buying a maintenance plan, not conditional on you replacing your system later, not conditional on anything except that you hired us and we did the repair. It applies to every repair we make, from a $150 igniter replacement in a furnace to a full compressor job. The written guarantee is standard on every ticket, not an add-on you have to ask for. If your AC goes down in August, three months after we fixed it, you call (832) 371-9862, and we come back. That’s the whole promise, and it’s the reason people in Houston call Cold Harbour first when something breaks.
Frequently Asked Questions About Our Guarantee
Yes. If a repair fails within 365 days, the return visit, the replacement part, and the labor to correct the work are all covered at no charge. No separate “parts only” fine print, no labor bill snuck in. The guarantee we hand you in writing says exactly that.
We’ll show you what we found and explain how it’s different from the original repair. You’ll get a written quote before any new work starts, and you decide whether to proceed. If the new problem turns out to be part of the same underlying issue we missed, the guarantee applies.
Call (832) 371-9862. A live person answers 24 hours a day, 7 days a week. Tell them the original repair date, and we’ll pull the work history and schedule the return visit. That’s the fastest way to get a tech back out to your home.
We service nine major residential HVAC brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. If your equipment is still under a manufacturer’s parts warranty, we’ll help you navigate that process, but our 365-Day Done Right Promise covers our workmanship independent of what the manufacturer covers.
Yes. The written price you get before work begins is the final price. It doesn’t go up at the door, after the diagnostic, or at the end of the job. That’s a core rule of The Kingswell Way and it applies on every call Cold Harbour runs in Houston.
