Mitsubishi Diamond Elite and Daikin Comfort Pro contractor since 1987 (NYC DOB #022359). A licensed NYC tech on-site, a signed written root-cause report by end of day, no upsell. If you approve the repair, the diagnostic fee is credited 100% toward the invoice.
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.
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.
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.
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.
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.
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.
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.
We dispatch a licensed Vinco tech, not a sales rep. Same-day in Manhattan and Brooklyn when booked before 11am. Same-day or next-morning in Queens, the Bronx, and Staten Island, prioritized by severity.
The on-site diagnostic fee is $199, credited 100% toward any approved repair or installation. If you take the report and walk, $199 is the only cost. There are no trip charges, no fuel surcharges, no add-ons.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Cooling, heating, and commercial. If your system is on this list we have factory training, parts access, and a tech who has opened one before.
