HVAC Contractors government contracts in Maryland

The federal government has already bought HVAC work in Maryland, and every one of those contracts is public record — filed under NAICS 238220, a code it shares with plumbing. Below is what our copy of that record says about the HVAC side of it: who won, which agencies bought, what the awards were worth, and which contract terms run out soon. Each row was selected by reading its own work description, and the ones we could not read confidently are counted rather than claimed.

Open under NAICS 238220 in Maryland — both trades, split further below

How to read this page: NAICS 238220 is titled "Plumbing, Heating, and Air-Conditioning Contractors" — the federal government files HVAC and plumbing under one code and does not separate them. This page is a filtered view of that code: we read each record's own work description and show the HVAC ones. 203 of the 500 awards we read describe HVAC work, and 252 describe both trades or say too little either way — those appear in no ranking on this page or on the plumbing one.

How to use Maryland award history to win the next contract

Award records tell you who you are really bidding against

A solicitation tells you what an agency wants. The award record tells you what it has actually been willing to pay, and to whom. Before you price a Maryland job, read the incumbent table above: if one company holds most of the awards under your NAICS code, you are bidding against an incumbent with past performance the evaluators already trust, and your proposal has to give them a reason to switch.

What the HVAC half of 238220 looks like

HVAC work under this code splits into two commercially different things that a NAICS code will never separate for you: equipment replacement — chillers, boilers, air handlers, rooftop units, cooling towers, ductwork — and recurring preventive maintenance. They are bought differently. Replacement inside a construction project carries Davis-Bacon wage determinations; a recurring maintenance contract is a service contract and carries Service Contract Act wage determinations instead, which is a different rate sheet and a different price. And any work that touches regulated refrigerant needs EPA Section 608 certified technicians under 40 CFR Part 82 — a technician credential, not a company one.

Period-of-performance end dates are your calendar

Most services work is re-competed near the end of its term. An award whose current end date lands in the next twelve months is the earliest honest signal that a new solicitation may be coming — early enough to introduce yourself to the contracting office, request a copy of the current statement of work, and be a known name when the notice posts. It is only a signal: option years exist, and agencies exercise them.

One NAICS code decides whether you count as small

Each solicitation names a single NAICS code, and the SBA size standard attached to that code is the line between bidding as a small business and bidding open. The table above shows what our seed of the SBA table holds: for some codes the code's own published figure, and for the rest only the figure published for its NAICS family, which those rows label as such. A family figure is a rough bearing, not the threshold you certify against — check your own average annual receipts against the code's own line in 13 CFR 121.201 before you self-certify. A wrong certification is the kind of mistake that gets a proposal thrown out after you have already done the work of writing it.

Prevailing wages on federal construction

Federally funded construction contracts over $2,000 carry Davis-Bacon Act prevailing wage requirements: the wage determination attached to the solicitation sets the minimum hourly rate and fringe benefits you must pay by trade classification and by county. Those rates go into your bid before your margin does, and they vary within Maryland — price from the determination attached to the specific solicitation, not from a state average. Our free wage-determination tool points you at the official figures.

Where these numbers come from

Award data on this page is federal contract spending published by USAspending.gov, filtered to a Maryland place of performance and the NAICS codes listed above. Open bids come from SAM.gov and state procurement feeds. We publish what the record says and label what it leaves blank — where a field is empty upstream, this page says "not reported" rather than filling it in.
