SBA Financing by Contractor Type
HVAC, plumbing, and electrical contractors each have different SBA eligibility considerations, acquisition structures, lender preferences, and expansion opportunities. Choose the guide that matches your business.
Each trade has distinct financing considerations — NAICS classification, acquisition dynamics, lender appetite, and common deal structures vary. Select your trade for a complete guide specific to your business.
SBA Loans for HVAC Contractors
HVAC contractors share NAICS 238220 with plumbing — meaning an existing HVAC operator can acquire a plumbing company with no down payment under the SBA expansion rule. Strong lender appetite driven by recurring service contracts and retirement-driven seller market.
- 0% down acquisitions for existing operators
- Cross-trade acquisitions (HVAC + plumbing)
- Shop building purchase and construction
- Partner buyouts and refinancing
SBA Loans for Plumbing Contractors
Plumbing contractors share NAICS 238220 with HVAC — the same expansion rule applies in both directions. Emergency service revenue, recurring maintenance plans, and commercial relationships make plumbing businesses strong SBA candidates.
- 0% down acquisitions for existing operators
- Cross-trade acquisitions (plumbing + HVAC)
- Equipment, fleet, and real estate financing
- Partner buyouts and refinancing
SBA Loans for Electrical Contractors
Electrical contractors are classified under NAICS 238210 — a separate code from HVAC and plumbing. Cross-trade acquisitions require a different structure, but SBA financing is fully available for acquisitions, real estate, construction, and expansion within the electrical trade.
- Business acquisitions — 10% down first-time buyers
- Commercial real estate purchase and construction
- Equipment and fleet financing
- Partner buyouts and refinancing

Why Trades Contractors Are Strong SBA Borrowers
SBA lenders evaluate businesses on cash flow predictability, owner experience, market demand, and collateral. Trades contractors score well on all of them.
Recurring service contract revenue — maintenance agreements, annual inspection programs, preferred customer plans — is particularly valuable to a lender because it is contractually committed, relatively immune to economic cycles, and easy to document. An HVAC company with 400 active maintenance agreements looks very different to an underwriter than a business with purely project-based revenue. The same applies to plumbing and electrical contractors with commercial service agreements or ongoing relationships with property management companies.
Beyond cash flow, trades businesses benefit from strong market fundamentals. Demand for licensed HVAC, plumbing, and electrical services is driven by housing stock age, commercial building requirements, and regulatory mandates — none of which disappear in an economic downturn. Lenders understand this, which is why trades acquisitions and real estate deals get approved at leverage levels that would be uncomfortable in more cyclical industries.
NAICS Codes and the 0% Down Expansion Rule
How the federal government classifies your business directly affects your SBA loan eligibility — and specifically whether you can acquire a competitor with no down payment.
| Trade | NAICS Code | Classification | 0% Down Available for Same-Trade Expansion? |
|---|---|---|---|
| HVAC Contractors | 238220 | Plumbing, Heating & Air-Conditioning Contractors | Yes — when acquiring another HVAC or plumbing business |
| Plumbing Contractors | 238220 | Plumbing, Heating & Air-Conditioning Contractors | Yes — when acquiring another plumbing or HVAC business |
| Electrical Contractors | 238210 | Electrical Contractors & Other Wiring Installation | Yes — when acquiring another electrical contractor |
HVAC and plumbing share NAICS 238220 — an HVAC contractor acquiring a plumbing company, or vice versa, qualifies as a same-industry expansion. Electrical contractors operate under 238210. For full detail on how the expansion rule works and what the four qualifying conditions are, see the individual trade pages linked above.

Frequently Asked Questions
Can an HVAC contractor buy a plumbing company with no down payment?
Yes — if the acquiring owner already operates a profitable business and the other expansion rule conditions are met. HVAC and plumbing contractors share the same federal industry classification, which means an acquisition between the two qualifies for the no-down-payment expansion rule. See the HVAC financing page for full detail on the four qualifying conditions.
What about an HVAC or plumbing contractor acquiring an electrical contracting business?
Electrical contractors are classified under a different federal industry code. The no-down-payment expansion rule requires the same classification, so a cross-trade acquisition would not qualify under that rule. However, a strategy that allows borrowers to carry up to $5M in SBA loans across two different industry classifications simultaneously may apply. Call us to discuss.
How long does it take to close an SBA loan for a trades business?
For a straightforward transaction with complete documentation, 45 to 75 days is a realistic timeline from application to closing. Deals that include real estate run closer to 75 to 90 days since an appraisal and typically a Phase 1 Environmental Report are required.
Can I finance equipment and vehicles along with a real estate purchase?
Yes — the SBA 7a can wrap real estate, equipment, vehicles, working capital, and closing costs into a single loan. If the real estate portion exceeds 51% of the total project cost, the loan qualifies for a 25-year amortization on the full amount.
What credit score do I need for an SBA loan as a trades contractor?
There is no SBA-mandated minimum credit score for loans above $350,000. Individual lenders set their own standards. Generally, a personal credit score in the mid-600s or above, with no recent delinquencies and no prior government loan defaults, is workable with the better lenders. What one lender declines, another will approve.
Can I use an SBA loan to buy out my business partner?
Yes — partner buyouts are a well-established use of the SBA 7a program. Under current rules, no equity injection is required if the remaining owner has been actively participating with the same or greater ownership interest for at least 24 months and the business debt-to-worth ratio does not exceed 9:1. When those conditions are met, the buyout can be financed at 100%.
