The SIC code for plumbing and HVAC contractors is 1711, "Plumbing, Heating and Air-Conditioning." It covers plumbing repair, heating and air-conditioning work, boilers, refrigeration, sprinkler systems, and related mechanical contracting. Primarily electrical contractors use SIC 1731, while standalone roofing and sheet metal contractors use SIC 1761.
Every business in our file is tagged with its SIC code. Pick a state or jurisdiction to see how many SIC 1711 plumbing and HVAC records we hold with a phone number.
SIC 1711 groups plumbing, heating, air-conditioning, and similar work under one four-digit code. NAICS separates a few activities that were historically grouped together, so the right NAICS code depends on the work being performed.
| SIC | SIC description | NAICS | NAICS description |
|---|---|---|---|
| 1711 | Plumbing, Heating and Air-Conditioning | 238220 | Plumbing, Heating, and Air-Conditioning Contractors |
| 1711 | Plumbing, Heating and Air-Conditioning | 238210 | Electrical Contractors and Other Wiring Installation Contractors, for environmental control wiring |
| 1711 | Plumbing, Heating and Air-Conditioning | 238910 | Site Preparation Contractors, for septic tank, cesspool, and dry-well installation |
If you found 1711 on a payment-processing or merchant-services form, that may be MCC 1711, "Heating, Plumbing, and Air Conditioning Contractors." MCC codes classify merchants for card payments, while SIC codes classify industries. The number and trade description are similar, but the systems are separate.
SIC 1711 covers several mechanical trades under the same four-digit code. NAICS provides finer separation for a few activities, while most plumbing and HVAC specialties remain under 238220.
Plumbing installation and repair, piping, gas line hookups, sewer hookups, sump pumps, water pumps, and related plumbing work.
Heating, ventilation, and air-conditioning installation, service, testing, balancing, and related sheet metal work performed as part of the HVAC job.
Boiler erection and installation, furnace repair, fuel-oil burner service, refrigeration, freezer work, and similar heating or cooling services.
Sprinkler system installation, steam fitting, mechanical contracting, solar heating apparatus, and other related piping or mechanical work.
The older SIC category includes drainage-system, septic-tank, cesspool, and dry-well construction work. Current NAICS separates this portion under Site Preparation Contractors.
Primarily electrical contractors use SIC 1731. Roofing and sheet metal contractors that are not performing the work as part of a plumbing, heating, or air-conditioning installation use SIC 1761.
Many people searching for the plumbing or HVAC SIC code are classifying a contractor or building a prospect list. If you are prospecting, SIC 1711 is the industry filter and the useful segmentation comes next.
In our portal, SIC 1711 narrows the business file to plumbing, heating, air-conditioning, and related contractors. From there you can layer on employee count, annual revenue, city, county, zip, area code, and contact name where available. The output is a CSV with the business name, phone number, address, SIC code, and the demographic fields you selected.
Common combinations include field-service software vendors targeting contractors by employee count and metro, equipment suppliers narrowing plumbing and HVAC firms by state and company size, and insurance, payroll, or fleet-service providers targeting contractors by region and revenue.
Established trade contractors can be relatively stable, but smaller firms can close, rebrand, relocate, or change phone numbers. Our US business data is refreshed quarterly, Canada data is refreshed annually, and we estimate roughly 90% accuracy on business records. Check refresh timing before a large campaign.
These are the available SIC 1711 records in the supplied business file, broken out by state and jurisdiction. Every available count below can be narrowed further by city, county, zip, employee count, or revenue inside the portal.
