How to bid HVAC and mechanical work in Maryland

1. Before you can bid at all

The entry ticket: the registrations buyers check, the licence the law requires for this trade, the certifications that change who can win, and the wage floors that set your labour line.

Registrations

• Register the business with the State Department of Assessments and Taxation and keep it in good standing; every certification below checks SDAT first.Source: dat.maryland.gov/businesses/Pages/default.aspx
• Get a federal EIN, then file Maryland's Combined Registration Application through Maryland Tax Connect for withholding and sales-and-use accounts.Source: www.marylandcomptroller.gov/content/dam/mdcomp/tax/filing...
• Register as a vendor on eMaryland Marketplace Advantage (eMMA): a two-step form, then pick every UNSPSC commodity code that could apply, because notifications only go out for checked codes.State agencies and most counties post formal solicitations there; Carroll, Harford, Howard and Baltimore County also run their own portals.Source: procurement.maryland.gov/wp-content/uploads/sites/12/2020...
• Keep a W-9, a certificate of insurance and a one-page capability statement ready; they are asked for on nearly every submission.Source: procurement.maryland.gov/how-to-do-business-with-the-stat...

The licence the law requires for HVAC and mechanical

• HVACR work for hire needs a licence from the Maryland Board of HVACR Contractors: a master (three years as a journeyman, 1,875 hours in the prior year, exam at 70%) or a limited contractor (two years as a journeyman, 1,000 hours, exam), with journeyman and apprentice licences below.Source: www.labor.maryland.gov/license/hvacr/hvacrlicreq.shtml
• Anyone who handles refrigerant needs federal EPA Section 608 certification.Source: www.labor.maryland.gov/license/hvacr/hvacrlicreq.shtml
• Mechanical permits and inspections are pulled from the county for replacements and new installs; term maintenance contracts usually do not need them.Source: www.labor.maryland.gov/license/hvacr/hvacrlicreq.shtml

Certifications that change who can win

• Small Business Reserve (SBR): a free self-certification inside eMMA, renewed yearly; SBR-designated state solicitations are open only to certified firms.Source: gomdsmallbiz.maryland.gov/Pages/SBR-Registration.aspx
• Minority Business Enterprise (MBE) through MDOT: at least 51% owned and controlled by socially and economically disadvantaged individuals, with a personal-net-worth cap; plan on 60 to 90 days from a complete application. MBE participation goals appear on many county and school bids.Source: www.mdot.maryland.gov/tso/pages/index.aspx?pageid=91
• Veteran-Owned Small Business Enterprise (VSBE): 51% veteran-owned, SBA size standards, no fee, renewed every three years; designated agencies aim 3% of spend at VSBE firms.Source: gomdsmallbiz.maryland.gov/Pages/VSBE-Program.aspx
• Montgomery County's Local Small Business Reserve Program (LSBRP) and Prince George's County-based business preference are separate county registrations that decide who may bid set-aside county work.Source: www.montgomerycountymd.gov/PRO/Programs/LSBRP/LSBRP.html

Wage floors

• Maryland Living Wage Law covers state service contracts of $100,000 or more ($500,000 for employers with 10 or fewer employees). Tier 1 (Anne Arundel, Baltimore City, Baltimore, Howard, Montgomery, Prince George's) is $17.54 an hour from September 29, 2026; Tier 2 is the rest of the state at a lower rate set yearly.Source: labor.maryland.gov/labor/prev/livingoverview.shtml
• Montgomery County's Wage Requirement Law sets $18.55 an hour on county service contracts from July 1, 2026.Source: www.montgomerycountymd.gov/office-procurement/division-bu...
• Prince George's County's living wage for county contractors is $18.10 an hour from July 1, 2026.Source: www.princegeorgescountymd.gov/boards-commissions/wage-det...

2. How buying works in Maryland

• Thresholds decide the form: small purchases are quotes by phone or email, formal sealed bids start at each county's own line (Carroll formalises above $25,000; St. Mary's above $50,000). Ask each buyer for their small-procurement list; that is where a new firm gets its first work.Source: www.carrollcountymd.gov/government/directory/comptroller/...
• An IFB (invitation for bids) goes to the lowest responsive, responsible bidder; an RFP (request for proposals) is scored on approach and price; an RFQ for qualifications shortlists firms before price. Read which one you are answering before you write a word.Source: procurement.maryland.gov/how-to-do-business-with-the-stat...
• Bid opening day is public: bids are read aloud and the tabulation is recorded. That sheet is the single most useful document in public bidding, and this site collects them.Source: procurement.maryland.gov/how-to-do-business-with-the-stat...
• Addenda can arrive any time before the due date and must be acknowledged on the bid form; an unacknowledged addendum is the most common reason a low bid is thrown out.Source: www.carrollcountymd.gov/government/directory/comptroller/...
• Late bids are returned unopened. Sealed paper bids must be at the purchasing office, not in the mail, by the minute stated.Source: www.carrollcountymd.gov/government/directory/comptroller/...

3. What Maryland buyers actually ask for in HVAC and mechanical

Counted from the bids we have read in full. Thin where the count is low; it grows as we read more.

4. How to price it

The craft, then the evidence: what this work actually went for at Maryland bid openings, and who has been winning.

• Maintenance contracts price per visit per unit type on a schedule (filters, belts, coils, controls checks), with on-call repair at hourly rates by class plus a stated parts markup; buyers compare the annual maintenance figure first.
• Replacement and upgrade IFBs are capital work: bid, performance and payment bonds, permit costs, and prevailing wage where the county's law applies.
• Response-time commitments carry a premium; read the liquidated-damages clause before pricing it.
• The tabulations below show accepted prices; the debrief shows your gap.

5. Starting from zero: the first 90 days

For someone who wants to start a HVAC and mechanical business and sell only to government. The order matters: the licence and the registrations gate everything else.

1. Weeks 1 to 2: entity, EIN, Combined Registration, general liability, auto, workers' compensation; confirm the qualifying individual's HVACR licence level and EPA 608 cards for every technician.
2. Weeks 2 to 4: eMMA registration with HVAC and mechanical commodity codes; SBR; a surety relationship, because capital HVAC bids need bid and performance bonds.
3. Weeks 4 to 8: small purchases: on-call service for a town, a library system, a housing authority.
4. Weeks 8 to 12: first term maintenance IFB; walk every site at the pre-bid and count units yourself.
