Get your free estimateThe Cold Harbour Heating and Air Miami Guarantee
A guarantee means nothing if it’s not in writing. That’s why every repair we complete in Miami comes with our 365-Day Done Right Promise, printed and handed to you before our technician leaves your driveway. If the repair fails within a full year, we return and correct the work at no charge. No phone calls to argue. No fine print to decode. No “that part isn’t covered” runaround. You get a written price before work begins, a written guarantee when the work is done, and a live person on the phone if anything goes wrong. That’s what standing behind our work means at Cold Harbour Heating and Air Miami.
What’s Covered
Here’s exactly what you can hold us to on every job, whether it’s an AC repair in Brickell, a furnace service in Coral Gables, or a full system installation in Kendall.
- Workmanship on every repair, guaranteed for 365 days. If a repair we performed doesn’t hold up within a year, we come back and do it again at no cost to you, full stop.
- Written price before any work begins. Our technician hands you the price in writing before a single tool comes out of the truck, and that number does not change at the door.
- Parts handling with full accountability. If a part we installed fails within the guarantee window, the return visit and the corrective work are on us, no additional charge.
- Cleanup as a standard, not a favor. We leave your home the way we found it, or cleaner. This is one of the five values of The Kingswell Way, and it’s not negotiable.
- On-time arrival within the window we give you. When you schedule with us, you get a specific window, and we show up in it. Your time in Miami traffic is valuable too.
- Background-checked, uniformed technicians on every visit. You’ll know exactly who is walking through your door before they arrive, and they’ll be trained on nine major residential HVAC brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard.
- Live-person phone coverage, 24 hours a day, every day. No voicemail trees. No after-hours answering service that just takes a message. You call, a person answers, every single time.

Our Satisfaction Promise
If something isn’t right, we want to know about it immediately, and we’ll make it right. Here’s the process: call us at (850) 810-1910, tell us what’s wrong, and we’ll schedule a return visit. If the issue falls within the 365-day window on a repair we performed, there’s no charge for the follow-up visit or the corrective work, period. If you’re not satisfied with something outside the guarantee window, call us anyway. Victor Mancini, the owner, has been doing this work since 2003, and he’d rather hear directly from you than have you quietly switch to another company. The Kingswell Way exists for this exact reason: 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. That last part matters most. A guarantee is only as good as the company’s willingness to honor it, and we built our entire operation around honoring it.
Licensed & Insured Backing
A written guarantee is only as strong as the company behind it, which is why our licensing and insurance matter to every Miami homeowner we serve. Cold Harbour Heating and Air Miami is licensed and insured, which means if something goes wrong on a job site, you’re protected. Insurance covers your property and the people working on it. Licensing means our technicians have met the state’s requirements to perform HVAC work safely and correctly. Combined with the 365-Day Done Right Promise, you’re covered by paperwork before we start, paperwork when we finish, and a real company that answers the phone when you need us. The name Cold Harbour comes from a roadside shelter where travelers waited out the weather. That’s the job: comfort in any season, backed by a guarantee you can hold in your hand.
