Engineers with nothingto sell you

We work in MEP — mechanical, electrical, and plumbing engineering. Mechanical is our focus. A large part of the work is reading contractor proposals: comparing scope against scope, checking equipment selections against the load, and finding the difference between two bids that look ten thousand dollars apart until you read what each one actually includes.

Homeowners get almost none of that. You get a one-page quote, a model number, a price, and a decision to make by Friday. The contractor may be excellent. The quote may still be unreadable. Those are separate problems, and only one of them is yours to solve.

What this site is

Plain explanations of what shows up in residential mechanical quotes: what a tonnage figure means and why a bigger one is not better, what a load calculation is and how to tell whether anyone did one, where the money actually goes in a replacement, what a scope of work should say, and what to ask when something on the page does not add up.

Every post assumes you are not in the trade and do not want to become an engineer. You want to spend a fair amount of money on the right system and then stop thinking about it.

The Quote X-Ray

The Quote X-Ray reads a pasted proposal and reports what the document says, what it never mentions, and where its price falls among comparable quotes other readers have submitted. A language model does the reading and writes the explanation; every number comes from ordinary arithmetic over the dataset, never from the model. If the model were asked for a local average it would produce a confident, plausible, invented one, which is exactly the thing this site exists to argue against.

The dataset started empty and grows only when someone chooses to contribute what they pasted. When there are fewer than five submitted quotes for a job type and area, the tool declines to place your price against them — that will be the answer for a while, and it is the honest one. Where it can, it shows a rough starting estimate instead: typical equipment pricing plus a standard labor multiplier, clearly labeled as a rule of thumb and never mixed in with real comparisons. See the dataset for which rows are submitted quotes and which are cost-model estimates.

What this site is not

• Not a lead generator. No contractor directory, no referral fees, no finder's cut.
• Not a manufacturer's site. No brand is paying for coverage here.
• Not engineering services. We are not designing your system, reviewing your specific proposal, or signing anything.
• Not a review site. We are not ranking the contractors in your area.
• Not an appraisal service. The Quote X-Ray compares one document against a small, self-reported dataset. It is a reading, not a valuation.

If a post ever reads like it is steering you toward buying something particular, we have gotten it wrong.
