Get your free estimateThe Cold Harbour Heating and Air New York Guarantee
We put our name on every repair we make in New York, and that means something specific. A cold harbour was a roadside shelter where travelers waited out bad weather – a place you could count on when conditions turned. That’s the standard Victor Mancini has run this company by since 2003. When we leave your home, you get a written guarantee that stays valid for 365 days. Not a handshake. Not a promise we hope you’ll forget. Paper, with our name on it, covering exactly what we did. If that work fails inside a year, we return and correct it at no charge. That’s the whole arrangement.
What’s Covered
- Workmanship for a full year. Every repair carries a written guarantee valid for 365 days from the date we complete the work.
- Parts we install. If a part we put in fails during the guarantee window, we replace it and redo the labor at no charge.
- The price we quoted. The written price you approve before work begins is the price you pay. It does not change at the door.
- On-time arrival. We show up in the window we gave you. If something delays us, a live person calls you – never a voicemail.
- Cleanup after the job. We leave your home cleaner than we found it. That includes hauling off old parts, packaging, and debris.
- Who walks through your door. Every technician is background-checked, uniformed, and trained on nine major residential HVAC brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard.

Our Satisfaction Promise
If something is not right after we leave, you call us. A live person answers – 24 hours a day, 7 days a week, every day of the year. No voicemail tree, no waiting until morning. You explain what happened, and we make a plan. If the repair failed within the 365-day guarantee period, we come back and fix it at no charge. No argument, no invoice, no fine print. If the issue is something different – maybe you want a second look at another part of the system, or you have a question about how something works – we’ll talk through it honestly and tell you what’s covered and what’s not, before any work starts. Victor Mancini’s position is simple: a guarantee only matters if it’s easy to use. So we wrote ours to be exactly that.
Licensed & Insured Backing
Any company can print the word “guaranteed” on a flyer. The real question is whether they’re still around to honor it. Cold Harbour Heating and Air New York is licensed and insured to perform HVAC work throughout New York, and we’ve been operating here since 2003 as part of the Kingswell network of independently owned and operated HVAC businesses. That network works to the same written standards we use on every job: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, come back if it fails. Those five points are The Kingswell Way, and they’re not marketing language. They’re the operating instructions. Licensing means we answer to New York regulators. Insurance means your home is protected if something unexpected happens. The guarantee means we answer to you.

AfterHow the 365-Day Done Right Promise Works
Here’s the sequence, because we think you should understand exactly what you’re getting before you ever pick up the phone. Step one: you call (934) 465-5501 and reach a live person. Step two: a Cold Harbour technician arrives at your New York home in the window you were given. Step three: the technician diagnoses the problem and hands you a written price before any tools come out. That price is fixed. Step four: you approve the work. Step five: the work is completed, the area is cleaned, and you receive a written guarantee covering that specific repair for 365 days. Step six: if the repair fails at any point in that year, you call us and we return to correct it at no additional charge. There is no seventh step. That’s the whole system.
What We Do Not Do
We don’t quote one price over the phone and change it at your door. We don’t leave a voicemail as our after-hours policy. We don’t ask you to trust us because we have a nice logo. We don’t do verbal guarantees that evaporate when there’s a problem. And we don’t hide behind subcontractors or third parties – the technician who shows up works for Cold Harbour Heating and Air New York, is background-checked, and is trained to service whatever major brand is already in your home. If we can’t fix it correctly, we’ll tell you that upfront rather than sell you a repair that won’t hold. That’s not a guarantee clause. That’s just how Victor runs the place.
Why New York Homeowners Have a Specific Set of Problems
New York buildings put real strain on HVAC equipment. Steam heat systems from the 1920s sit next to ductless mini-splits installed last year. Window units share walls with central air retrofits. High-rise apartments run off building-wide chilled water loops while brownstones in Brooklyn and Queens carry individual condenser units on roof decks. We work on all of it. The guarantee matters more here because the systems are uneven – a thirty-year-old furnace in a prewar building needs different attention than a five-year-old heat pump in a new construction condo. What doesn’t change is the paper we hand you when the work is done. 365 days, written down, covering the repair we made. In a city with this much housing variety, consistency is the rare thing, and that’s what we sell.
Frequently Asked Questions About Our Guarantee
It covers the specific repair we performed, in writing, for 365 days from the date of completion. If that repair fails within that window, Cold Harbour Heating and Air New York returns and corrects the work at no additional charge. You don’t pay for parts, labor, or a return visit. Call (934) 465-5501 and a live person will schedule the return.
You get it after the work is completed, before the technician leaves your home. It’s printed, dated, and specific to the repair that was made. The technician reviews it with you so there’s no ambiguity about what’s covered. If you have a question, you ask it right then, with the person who did the work standing in front of you.
It’s fixed. The price is written and handed to you before any work begins, and it does not change at the door. No surprise fees, no “we discovered something else” upcharge. If the technician finds an additional issue during the repair, they’ll stop, explain it, and give you a new written price to approve. You decide. The original quote stands until you say otherwise.
You call us and we come out to diagnose it. You’ll get the same written-price-before-work treatment, the same background-checked technician, and the same honest conversation about whether it’s the same issue or something new. We don’t stop being responsible for our work on day 366, but the written guarantee covers exactly what it says: one full year. After that, we’ll treat you fairly and tell you the truth about what you need.
Yes. The 365-Day Done Right Promise applies to every repair we make – air conditioning, furnace, or otherwise – regardless of the brand of equipment in your home. Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, American Standard: the guarantee is the same paper, the same 365 days, the same return-and-correct commitment. Call (934) 465-5501 if you have a specific repair in mind and want to talk through how the guarantee applies.
The Kingswell Way is the five-point standard every independently owned and operated Kingswell business works to: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, and come back if it fails. Cold Harbour Heating and Air New York has operated under those standards since 2003. Your guarantee isn’t a policy that might apply. It’s part of the operating agreement between us and the network we belong to.
If you want to talk through what the guarantee means for your specific system, call (934) 465-5501. A live person answers, any hour, any day. Estimates are free, and you’ll have the written guarantee before the technician leaves.
