HVAC Contractors government contracts in Connecticut

The federal government has already bought HVAC work in Connecticut, 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 Connecticut — 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. 165 of the 484 awards we read describe HVAC work, and 235 describe both trades or say too little either way — those appear in no ranking on this page or on the plumbing one. How the split works · 238220 in Connecticut with no work-description filter

How this page separates HVAC from plumbing

It does not separate them by NAICS, because NAICS cannot. The U.S. Census Bureau gives 238220 the title "Plumbing, Heating, and Air-Conditioning Contractors" — one code, both trades, deliberately. A contracting officer filing a sewer-line repair and one filing a chiller replacement use the same six digits, and no field in the federal record tells the two apart.

So this page reads the work description on each record and keeps the ones that describe HVAC work. The words it reads as HVAC: hvac, air conditioning, chiller, boiler, furnace, ductwork, rooftop unit, heat pump, ventilation, air handler, cooling tower, refrigeration. Words that are excluded from a scope — "no HVAC work is included", "HVAC by others" — do not count as signals.

Where the text says both trades, or says neither clearly enough, this page claims nothing. Those rows are counted in the table beside this and then left out of every ranking here and on the plumbing page. A missed contract costs this page one row; a wrongly claimed one would tell you something false about who is winning your work.

This filter is our reading of published text. It is not a federal classification, and the government does not maintain one for these two trades.

The agencies buying hvac contractors in Connecticut

Knowing which agency actually spends the money in your state tells you whose forecast to read, whose industry days to attend, and whose small-business specialist to call. Counts and dollars are across the 165 of 484 awards on record under this code whose work description reads as HVAC work. The table is ranked by reported dollars, which is not the same order as how often an agency buys — one large contract can outrank a buyer that awards small jobs every month, so read the awards column too.

Connecticut hvac contractors contracts whose term ends within a year

The period of performance on these awards currently ends in the next twelve months. That is a signal worth watching, not a promise: many contracts carry option years the agency can exercise, which pushes the end date out without any new competition. Only awards this page reads as HVAC work are listed; the plumbing side of 238220 has its own radar on its own page.

The NAICS codes hvac contractors work is bought under

A federal solicitation carries exactly one NAICS code, and that code decides two things at once: whether the bid reaches your feed, and what size standard you have to be under to bid it as a small business. Award counts are across the 165 of 484 awards on record under this code whose work description reads as HVAC work.

NAICSIndustrySBA size standardAwardsReported total
238220Plumbing, Heating, and Air-Conditioning ContractorsNAICS 238 family standard: $19.0M average annual receiptsNot 238220's own published figure165$41,173,626

Industry titles are the official 2022 U.S. Census NAICS titles. Size standards come from our seed of the SBA table at 13 CFR 121.201. Where that seed lists the six-digit code itself, the figure shown is that code's own published standard. Where it does not, the row says so and shows the figure published for the NAICS family the code sits in — that is the family's number, not this code's, and sibling industries do not always share one. A blank means the seed carries neither, never that no standard applies. Confirm the code's own line in the current SBA table before you certify anything. The award columns count only the rows this page reads as HVAC work. The code's own count — 484 awards, both trades — is in the panel above.

1 solicitation is open under NAICS 238220 with a Connecticut place of performance, but none of the 1 we read describe HVAC work. The same feed with no work-description filter is on the Connecticut construction-trades page.

Also open under 238220 — trade unclear from the text

These describe both trades, or say too little for us to tell. They are not counted as HVAC work anywhere on this page.

Past HVAC solicitations in Connecticut

Solicitations whose deadline has passed. You cannot bid these, and every page says so at the top — but the scope, the requirements and the issuing office are still there to read, which is the cheapest preparation there is for the next time the same agency buys the same work.

We hold no closed hvac contractors solicitations for Connecticut yet. The archive fills as the bids we track pass their deadlines — an empty archive here means our record is young, not that nothing has ever been solicited.

How to use Connecticut 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 Connecticut 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 Connecticut — 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 Connecticut 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.

Connecticut hvac contractors contracts — common questions

How many federal hvac contractors contracts have been awarded in Connecticut?
We hold 484 federal contract awards with a Connecticut place of performance under NAICS 238220, which covers HVAC and plumbing together. Of the 484 we read in full, 165 describe HVAC work, with periods of performance starting between Aug 1, 2012 and Aug 3, 2026. The remaining 319 either describe plumbing work or do not say clearly enough for us to claim them.
Which NAICS codes cover hvac contractors government work?
One: 238220. Its official U.S. Census title is "Plumbing, Heating, and Air-Conditioning Contractors", so HVAC and plumbing are filed under the same six digits and the code alone cannot tell them apart. That is why this page is a filtered view of 238220 rather than a separate code — we read each record's own work description. The federal government does not classify the two trades separately, and nothing on this page should be read as saying it does.
Who buys hvac contractors services in Connecticut?
Across the 165 of 484 awards on record under this code whose work description reads as HVAC work, the agencies that bought most often are Department of Defense, Department of Veterans Affairs, Department of Homeland Security. That is by number of awards; the table on this page ranks the same agencies by reported dollars, which can put a different name first when one large contract outweighs many small ones.
Are there open hvac contractors bids in Connecticut right now?
1 open solicitation with a Connecticut place of performance matches NAICS 238220 as of this page load. That code covers HVAC and plumbing together, so we read the text of each one: 0 of the 1 we read describe HVAC work. Each carries a plain-English summary of what the job is and what disqualifies bidders.
Why do plumbing jobs appear under the HVAC NAICS code?
Because the code is theirs too. 238220 is titled "Plumbing, Heating, and Air-Conditioning Contractors", so a sewer repair and a chiller replacement reach the record under identical six digits and nothing in the federal data separates them. This page reads each record's work description instead, for these words: hvac, air conditioning, chiller, boiler, furnace, ductwork, rooftop unit, heat pump, ventilation, air handler, cooling tower, refrigeration. 235 of the 484 awards we read describe both trades or say too little either way, and are excluded from every ranking here. The same records with no work-description filter are on the Connecticut construction-trades page.
Do I need an EPA certification to service federal HVAC equipment?
To handle regulated refrigerants, yes. EPA Section 608 technician certification is required nationwide under 40 CFR Part 82 Subpart F to maintain, service, repair, or dispose of appliances containing regulated refrigerant, and it is the technician who is certified, not the company. It applies on federal work exactly as it does on commercial work; the solicitation will also list any state HVAC licensing it requires on top of it.
