HVAC & Mechanical · five boroughs

No heat and no hot water are the two orders a landlord cannot sit on.

HPD writes heat and hot water violations as Class C — immediately hazardous — and during heat season it writes a lot of them. A Class C order means an inspector is coming back and the penalty is already accruing. We watch every heating, hot water and mechanical order in the five boroughs and hand you the agent on file with the order text and the date.

Price

HVAC & Mechanical leads, $199 a month.

First month free on Alert. No contract, cancel any time. That works out to about $3 per ranked HVAC lead with the owner or managing agent already named on it.

The arithmetic, in HVAC job values

One job. That is the whole break-even.

Mechanical work carries the second highest median declared value of any division we track.

Job values are the declared valuations filed with the City on work at the buildings we score, not our estimates. Where a trade has too few declared values to be honest about, we do not publish a median — which is why there is no mold or lead page here yet.

One real record, start to finish

What a HVAC lead actually looks like

Public record, pulled from the feed, scored, and handed over with the contact resolved. This is a real open violation — the agent's name is the part you are paying for, so it is withheld here.

The Play

Class C, entire apartment, and the correction date is already behind the issue date — HPD does that when the condition is hazardous enough that correction was due on notice. Do not quote a survey. Offer to be there today and price the riser afterwards.

Every lead carries one of these. It is the difference between a row of data and knowing what to say when they pick up.

Why this is not a lead list

Marketplace leads sell intent. A violation is an obligation with a date on it.

A marketplace HVAC lead is a homeowner comparing three quotes on a condenser. A Class C no-heat order is a building with tenants calling 311 and a violation that escalates while the landlord shops around.

Heat season compresses everything. The value of knowing on the morning the order posts, rather than a week later, is the entire product — and no marketplace is built to deliver that.

Marketplaces sell intent. We sell obligation. Obligation has a date on it.

How it works

Four steps, every night, before you are awake.

1

We read the city, nightly

Fourteen datasets — DOB, ECB, HPD, FISP — refreshed every night. See every one on the data page.

2

We keep the ones with a deadline

Most of what the city publishes is paperwork. We keep records that carry a correction date, a filing date or an unpaid balance — something that forces a decision.

3

We name the human

Owner of record, or the managing agent registered with HPD where one is on file, with a confidence band on the resolution so you know how hard the number was to find.

4

It is in your inbox before you open the truck

Ranked, filtered to your trade and boroughs, with The Play on each one. 6:00am on First Look, 9:00am on Alert and Pro.

We are a commercial general contractor that got tired of buying leads from people who had never run a job. That is the whole origin story.

Do not take the numbers on trust.

Every figure on this page is read live from the same database that builds the digest. The data page lists all fourteen city datasets, the record counts, when each was last refreshed, and the open count for every division we sell.

Questions

Hvac contractors ask these first.

Is this only heat season?

No. Hot water orders run all year and mechanical work does not stop; heat season raises the volume, it does not create it.

Boilers or unitary equipment?

Both appear, because HPD writes to the failed condition rather than the equipment. The order text tells you which before you call.

How fast do these move?

Faster than anything else we carry. A Class C is the strongest argument for the early delivery tier.

What does it cost, and is there a contract?

Alert is $199 a month with the first month free. No contract, cancel any time. Pro is $399 and First Look is $899.

How many other contractors get the same lead?

Capped by tier rather than sold to whoever turns up. The point of a cap is that the lead is still worth calling when you get it.

Where does the data come from?

NYC Open Data — DOB, ECB, HPD and the FISP filings — plus the registration and tax roll records used to resolve the contact. It is public record. The work is in filtering it, ranking it and naming the human, and that is what you are paying for.
