Get your free estimateThe Cold Harbour Heating and Air San Jose Guarantee
We fix heating and cooling systems in San Jose, and we stand behind the repair with a written guarantee that’s valid for a full 365 days. Not a verbal promise. Not a handshake. A piece of paper you keep in a drawer. If the repair fails at any point within that year, we come back and correct the work at no charge. That’s the entire guarantee, written down before the technician leaves your driveway. Victor Mancini, Owner, has operated this way since 2003, and it’s never been negotiable.
What’s Covered
- Workmanship for 365 days. Every repair we complete in San Jose carries a written guarantee valid for one full year from the day the work is done.
- Parts we install. If a part we put in fails within the guarantee window, we replace it and redo the labor at no cost to you.
- The price before the work. You get a written price handed to you before a single tool comes out, and that number does not change at the door.
- Cleanup on every job. We leave your San Jose home the way we found it, or cleaner. Drop cloths, shoe covers, and a full sweep of the work area are standard.
- Arrival within the window we give you. When we say a technician will be there between 9 and 11, that’s when we show up. If something changes, a live person calls you.
- A technician who knows your system. Our team is trained on nine major residential HVAC brands, including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard.
- The guarantee, on paper. Before the technician leaves, you get the written guarantee in hand. It states exactly what’s covered and for exactly how long: 365 days.

Our Satisfaction Promise
If a repair doesn’t hold, we come back. That’s the short version. The longer version is this: our 365-Day Done Right Promise means that if the repair fails for any reason within 365 days of the original service date, Cold Harbour Heating and Air San Jose returns and corrects the work at no charge. No arguments, no re-diagnosis fee, no “well, that’s a different part” runaround. We put the guarantee in writing before we leave the first time, so there’s no ambiguity about what’s covered. If you’re not satisfied with how the work was done, or if something feels off a month later, call us. A live person answers the phone 24 hours a day, 7 days a week, and we will schedule the return visit. That’s the way we’ve worked since 2003, and it’s core to The Kingswell Way: 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.
Licensed & Insured Backing
A written guarantee is only as good as the company behind it. Cold Harbour Heating and Air San Jose is licensed and insured, and we carry the coverage that protects your home and our team while we work. That matters when a technician is on your roof, in your attic, or working on a gas furnace in your San Jose garage. Insurance isn’t just paperwork. It’s the real financial backing that stands behind the guarantee. If something goes wrong, you’re not left holding the bill. We’re independently owned and operated as part of the Kingswell network, which means our standards are written, not optional. Every technician who walks through your door is background-checked and uniformed, so you know exactly who you’re letting into your home. The guarantee is the promise. The licensing and insurance are what make the promise enforceable.
Why This Guarantee Exists
The name Cold Harbour comes from an old roadside shelter where travelers waited out bad weather. The job was simple: give people a place to stay warm and dry until the storm passed. That’s what we do for San Jose homes. Your furnace or air conditioner is the shelter now. When it fails, you’re stuck waiting out the weather. Our guarantee exists because a repair that doesn’t hold isn’t a repair. It’s an interruption. Victor Mancini started this company in 2003 with a straightforward idea: if we’re not willing to guarantee the work in writing, we shouldn’t be doing it. That hasn’t changed in more than two decades.

AfterHow the 365-Day Done Right Promise Works
Here’s the process, step by step, so there’s no mystery. First, you call us. A live person answers, day or night. We schedule a visit and give you a two-hour window. The technician shows up in that window, listens to what’s wrong, and diagnoses the problem. Before any work begins, you get a written price. You approve it. The work is done. The area is cleaned. Then, before the technician leaves, you receive the written guarantee, signed and dated. That guarantee covers the repair for 365 days. If the same repair fails within that year, call us. We come back. We fix it. You pay nothing. That’s the entire system, and it’s worked for thousands of San Jose homeowners.
What We Don’t Cover (And Why We’re Clear About It)
We’re honest about the limits of the guarantee, and you should know them. The 365-Day Done Right Promise covers the repair we performed. It does not cover unrelated failures, damage from misuse, or issues caused by factors outside the original repair. If a different component fails, that’s a new repair and a new diagnosis. We don’t hide behind fine print, and we don’t invent exclusions after the fact. If there’s ever a question about whether something is covered, we discuss it with you directly and come to a fair answer. In practice, if we touched it and it failed, we make it right.
What This Means for San Jose Homeowners
San Jose weather is mild most of the year, but when the temperature spikes in July or dips in January, your HVAC system matters. A failed air conditioner in a Willow Glen summer or a dead furnace in an Almaden Valley winter isn’t just uncomfortable. It’s a problem that needs solving today. Our guarantee means you’re not gambling on a repair. You have a written commitment that the work will hold for a year. That’s real protection, and it’s why homeowners in San Jose call us when they want the job done right the first time. Call (669) 800-4179 for service backed by a guarantee you can hold in your hand.
