What if I just want a written estimate, not a diagnostic?

If you already know what you need (a new mini-split, a boiler replacement, a duct retrofit) skip the diagnostic and use the contact form at /contact or call (212) 810-0915 for a free estimate. The $199 diagnostic is for repair-shaped questions where the root cause is unknown. Installation, replacement, and remodeling estimates are always free.

Yes for installations and replacements. Mini-split, central AC, boiler, furnace, ductwork, VRF, and rooftop replacement estimates are always free, written, and itemized. The $199 diagnostic fee covers the on-site labor for repair-shaped questions where a tech needs to open the unit, take readings, and figure out why something is failing.

Do you handle co-op board approvals and Certificates of Insurance?

Yes. We carry $2M / $4M general liability with a $5M umbrella, which covers the limits most Manhattan and downtown Brooklyn buildings require on a COI. We pull and file the NYC DOB permits ourselves under license #022359 (we do not subcontract our license number), produce alteration agreement-ready scope letters, and coordinate with the building engineer or managing agent on access, freight elevator scheduling, and noise windows. For larger jobs, we orchestrate engineering plans, DOB filings, and special inspections end-to-end so the customer gets a turn-key design and install. See https://www.vincomechanical.com/commercial-hvac-permits-nyc for the permit playbook. Our written diagnostic reports are formatted to be acceptable as supporting documentation in a board package.

What kind of written report do I get?

A signed PDF on Vinco letterhead containing: the date and on-site time, the unit make and model, observed symptoms, measured values (refrigerant pressures, static pressure, temperature splits, electrical readings), the diagnosed root cause, a repair-vs-replace recommendation, and itemized parts and labor pricing. Every Vinco tech holds EPA Section 608 certification. This is the format your co-op board, building engineer, insurance adjuster, or commercial buyer expects to see.

The credentials

Authorizations that very few NYC contractors actually carry.

The reason we get called for diagnostics on co-op boards, hotel chains, restaurant groups, and Class A office buildings is not marketing. It is the specific manufacturer authorizations and insurance limits below. Most NYC HVAC contractors do not hold all four.

Mitsubishi Diamond Elite Contractor

Top tier of the Mitsubishi Electric contractor program. Not the residential Diamond tier the manufacturer hands out broadly: the Elite commercial tier with City Multi VRF training, factory parts access, and the extended labor warranty. There are fewer than two dozen Diamond Elite contractors in all of New York City.

Daikin Comfort Pro

VRV factory training, parts access, and the extended manufacturer warranty path. We can pull warranty parts overnight on most VRV4 and VRV5 platforms, which matters when a high-rise condenser is down and the building is full of tenants.

NYC DOB Contractor #022359

We file our own permits under our own license. We do not rent another contractor's number, we do not subcontract our license number, and we are responsible for our own DOB inspections. If a job needs an alteration permit (Alt-2 or Alt-CO), we file it.

Sister company Metal Men Mechanical

In-house ductwork shop in Brooklyn: rectangular, spiral, kitchen grease, exposed architectural. When a project needs custom duct, we make it in-house instead of waiting two weeks for a sheet metal subcontractor. Most NYC HVAC contractors call out for sheet metal, which adds time, markup, and a hand-off where things slip.

We dispatch across Manhattan, Brooklyn, Queens, the Bronx, and Staten Island from our Brooklyn HQ. After you book, the dispatcher confirms your slot, prioritized by severity.

After the visit

You leave with a written answer, not a follow-up sales call.

We do not run commission-based sales reps. The technician who shows up writes the report and emails it to you. You decide what to do with it.

01
On-site walkthrough
Tech walks you through findings with photos of any issues, on the spot. You see what they see. Questions answered while the unit is still open.
02
Written report
Signed PDF with root cause, measured values, itemized parts and labor, and a repair-vs-replace recommendation. Sent by email after the visit.
03
You decide
Approve a major repair or replacement (the $199 diagnostic fee is credited dollar-for-dollar against the invoice; the $49 travel fee always applies) or take the report and walk for $248. No pressure, no follow-up sales calls.
04
If you approve
We schedule around your operations and your building's freight and noise windows. Most common failures are fixed on the spot because the parts are already on the truck.

Questions

Plain answers, no fine print.

The most-asked questions before booking. If yours isn't here, call (212) 810-0915. The dispatcher answers 24/7.

01What does a Vinco HVAC diagnostic actually include?

A licensed NYC HVAC technician performs a full system inspection: airflow and static pressure, refrigerant levels and leak scan, electrical components (capacitor, contactor, control board), thermostat calibration, drain line and condensate, filter and coil condition, and any error history pulled from the unit. You receive a written report with root cause, repair-vs-replace recommendation, and itemized parts and labor pricing. Typical on-site time is 45 to 75 minutes.

02Is the diagnostic fee really credited toward the repair?

Yes, on major repair or replacement. The $199 diagnostic fee is credited dollar-for-dollar as a line item on the repair invoice (not a discount). The $49 travel fee is never credited. If you take the report and walk, the visit cost is $199 + $49 = $248. New system estimates (heat pumps, RTUs, VRF, boilers, central air) are free with no obligation. Full rate sheet at /rates-and-financing.

03How does scheduling work after I book?

After you submit the form (or call (212) 810-0915), the dispatcher confirms your slot by text or phone. Dispatch is prioritized by severity, so a no-cool call in July moves ahead of a routine pre-season inspection. We dispatch from our Brooklyn HQ at 993 Grand Street to all five boroughs.

04Do you service all five NYC boroughs?

Yes. Dispatch covers Manhattan, Brooklyn, Queens, the Bronx, and Staten Island from our Brooklyn HQ at 993 Grand Street. We file every job under NYC DOB Contractor #022359, and our techs carry $2M / $4M general liability with a $5M umbrella, the limits most Manhattan and downtown Brooklyn buildings require on a Certificate of Insurance.

05What types of HVAC systems do you diagnose?

Central air, ductless mini-splits (Mitsubishi, Daikin, LG, Fujitsu, Samsung), VRF and VRV, heat pumps including hyper-heat cold-climate units, rooftop units, fan coils, PTAC. On the heating side: gas and oil furnaces, gas and oil boilers, one-pipe and two-pipe steam. Commercial: City Multi VRF, Daikin VRV, Carrier and Trane rooftops, kitchen exhaust and makeup-air units, BMS-integrated systems.

06What happens after the diagnostic?

The technician walks you through findings on-site with photos of any issues. You receive a written report after the visit with itemized parts and labor and a repair-vs-replace recommendation. You decide whether to proceed, with no pressure. On a major repair or replacement, the $199 diagnostic fee is credited dollar-for-dollar against the invoice. The $49 travel fee always applies. If you take the report and walk, the visit cost is $199 + $49 = $248 and you still leave with a documented diagnosis you can hand to another contractor or your insurance carrier.

07Do I have to be home for the diagnostic?

Ideally yes, so the tech can show you the issue in person and you can ask questions while they have the unit open. If you cannot be there, we coordinate access with your super, doorman, or managing agent, capture photos and a video walk-through, and review findings by phone before sending the written estimate.
