What you get

A working system and a written report your co-op board will accept.

The point of a diagnostic is not the visit. The point is the answer you walk away with: what is wrong, what it costs to fix, whether it is worth fixing, and a piece of paper your building engineer, your insurance adjuster, or the next contractor can actually use. Here is what you get for the $199 on-site fee.

  • 01

    A working system

    Most common failures (capacitor, contactor, blower motor, low refrigerant, clogged condensate, dirty coil, failed igniter) are diagnosed and resolved on the first visit. Common parts are on the truck.

  • 02

    A written report your building accepts

    Signed PDF on Vinco letterhead with root cause, measured values (pressures, static, electrical, temperature splits), itemized parts and labor, and a repair-vs-replace recommendation. The format your co-op board, building engineer, insurance adjuster, or commercial buyer expects to see.

  • 03

    A real-cost number

    Written estimate before any repair starts. The $199 diagnostic fee credits 100% toward any approved work. If we cannot fix it on the spot, you get firm pricing for the return visit, not a vague range.

  • 04

    A second opinion

    If another contractor already gave you a number, we will diagnose against their proposal. About one in five second opinions we run finds a fix that is meaningfully smaller than the original quote. We bill diagnoses, not panic.

  • 05

    A licensed NYC tech, not a salesperson

    Every Vinco tech holds EPA Section 608 universal certification. Every install is filed under NYC DOB #022359. We do not run commission-based sales reps and we do not subcontract the licensed work.

  • 06

    An honest answer

    Sometimes the answer is "this can wait until spring." Sometimes the answer is "this is a $200 capacitor, not the $25,000 replacement someone quoted you." If your system has years of life left, we will say so. If it is past end-of-life, we will say that too.

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.

01

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.

02

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.

03

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 the licensed work, and we are responsible for our own DOB inspections. If a job needs an alteration permit (Alt-2 or Alt-CO), we file it.

04

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. Same-day in Manhattan and Brooklyn when booked before 11am. Same-day or next-morning in the outer boroughs, 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. The report is in your inbox the same day, usually within 4 hours. You decide what to do with it.

  1. 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.

  2. 02

    Written report by end of day

    Signed PDF with root cause, measured values, itemized parts and labor, and a repair-vs-replace recommendation. Sent by email the same day, usually within 4 hours of the visit.

  3. 03

    You decide

    Approve the repair (the $199 diagnostic fee is credited 100% toward the invoice) or take the report and walk. No pressure, no follow-up sales calls.

  4. 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.

Eleven things people ask before booking. If your question is not 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. The full $199 applies to any repair or installation you approve, with no fine print. If the recommended fix is $600, you pay $401. If you decide not to proceed, the written report is yours to keep and $199 is the only cost. The credit applies to repair invoices and to estimates you book within 30 days of the diagnostic.
03How fast can I get a same-day HVAC diagnostic in NYC?
Book before 11am and we target same-day arrival in Manhattan and Brooklyn. Queens, the Bronx, and Staten Island typically land same-day or next-morning depending on dispatch volume. Same-day dispatch is prioritized by severity, so a no-cool call in July moves ahead of a routine pre-season inspection.
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 by end of day with itemized parts and labor and a repair-vs-replace recommendation. You decide whether to proceed, with no pressure. If you approve the repair, the full $199 is credited toward the invoice. If you take the report and walk, 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. About 30% of our diagnostics are run with the customer not on-site.
08What 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 written estimate. The $199 diagnostic is for repair-shaped questions where the root cause is unknown. Installation, replacement, and remodeling estimates are always free.
09Are estimates 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.
10Do 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 the licensed work), produce alteration agreement-ready scope letters, and coordinate with the building engineer or managing agent on access, freight elevator scheduling, and noise windows. Our written diagnostic reports are formatted to be acceptable as supporting documentation in a board package.
11What 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, itemized parts and labor pricing, and the technician's EPA Section 608 certification number. This is the format your co-op board, building engineer, insurance adjuster, or commercial buyer expects to see.
