Mainline Plumbing, AC & Electrical — three Florida state licenses, one truck, 24/7 live-answering line.

It means Mainline Plumbing Service, Inc. — the Pompano Beach legal entity — holds three active Florida DBPR contractor licenses simultaneously, one for each trade: CFC1429264 for plumbing, CAC1823791 for air conditioning, and EC13003477 for electrical. The three license numbers are published on the mainlineplumbingservice.com /about-us/ page verbatim. Every other plumbing vendor on Palm Build's directory carries a single CFC license and refers AC and electrical scope out to a second vendor. Mainline does not. The operational implication is that one Mainline service van and crew can perform plumbing, HVAC, and electrical work on the same visit — no second-trip scheduling, no two-vendor coordination, no scope-handoff gap.

Yes. Because all three trade licenses are held under one entity, the techs on a single Mainline service van are qualified to perform plumbing, HVAC, and electrical scope under the same dispatch. The most common Palm Build referral scenario where this matters: a water-damage call exposes an electrical-safety risk (energized standing water near outlets, GFCI failure during cleanup) or a failing AC condensate line that has been the hidden source of a recurring leak — Mainline resolves all three scopes on one visit instead of three separate dispatches across three vendors. Call (954) 280-5597 to confirm scope before the truck rolls.

Yes — three active Florida DBPR licenses confirmed: CFC1429264 (Certified Plumbing Contractor), CAC1823791 (Certified Air Conditioning Contractor), EC13003477 (Certified Electrical Contractor). All three are published on the mainlineplumbingservice.com /about-us/ page and verifiable on myfloridalicense.com. Insurance coverage and bonded status are not publicly published on the website — Palm Build recommends asking the Pompano Beach office at (954) 280-5597 for a current Certificate of Insurance before any commercial-scope job.

Yes — Mainline publishes a 24/7 live-answering line on the dedicated /contact-us/24-7-emergency-services/ page. Calls are answered by a live human around the clock, not voicemail. The honest framing: standard same-day dispatch runs Monday–Saturday 8:00 AM – 7:00 PM per the /contact-us/ page; outside that window, the answering team triages and routes emergency calls to the on-call tech. Some aggregator listings show 24/7 dispatch — that is wrong about routine service, but the live-answering line is real and is the right number to call regardless of hour.

It depends on which date you anchor on. Mainline self-states 'since 2012' on multiple service pages — the operational founding date under Andrew DiLaurenzio. The Florida Sunbiz domestic profit corporation Mainline Plumbing Service, Inc. was registered on October 3, 2013 — the legal-entity formation date. The BBB Pompano Beach profile (0633-90612326) records a business-start date of April 23, 2015 — the BBB-tracking date. All three are accurate for what they measure. We surface the 2012 self-stated date because that is the operational continuity date the owner uses; the 2013 corporate registration is when the legal entity formed; the 2015 BBB date is when the BBB began tracking.

Mainline dispatches across 25 Broward and south-Palm-Beach-County cities from a four-office operational footprint: Pompano Beach (HQ), Coral Springs, Boca Raton, and Fort Lauderdale. The full active list: Pompano Beach, Fort Lauderdale, Deerfield Beach, Coral Springs, Coconut Creek, Parkland, Lighthouse Point, Oakland Park, Plantation, Davie, Dania Beach, Hallandale Beach, Hollywood, Margate, Lauderhill, Lauderdale Lakes, Tamarac, Sunrise, Weston, Miramar, Pembroke Pines, Aventura, Boca Raton, Delray Beach, and Boynton Beach. The vendor's published service-area page also lists smaller Broward incorporated areas (Cooper City, Pembroke Park, Southwest Ranches, West Park, Hillsboro Beach, Lauderdale-by-the-Sea) that are not yet in Palm Build's implemented-cities registry — those are listed in the Cities to Revisit section.

Yes — tankless water heater scope is published as a dedicated /plumbing-services/tankless-water-heater-installation/ page, with separate /tankless-water-heater-repair/ and /tankless-water-heater-maintenance/ pages. Tankless conversions matter for Broward County homes upgrading from 50-gallon storage tanks for endless hot water capacity and lower long-term operating cost. Brand-name install partnerships (Rinnai, Navien, etc.) are not publicly listed on the site — call (954) 280-5597 to confirm current install-brand options before the dispatch.

Yes — Mainline is the eighth plumber in our Trusted Vendors program and the only multi-trade vendor on the directory. The four-office Broward + south-PBC operational footprint slots between F1's Miami-Dade-and-Broward arc and Flamingo's WPB Treasure-Coast anchor. When a water-restoration job in Pompano Beach, Fort Lauderdale, Coral Springs, Parkland, Coconut Creek, Boca Raton, Delray Beach, or eighteen other Broward and south-PBC cities needs a permitted plumbing repair to fix the source of the loss — and especially when the loss touches electrical-safety scope (energized standing water, GFCI failure during cleanup) or HVAC scope (a failing AC condensate line as the hidden source) — Mainline is the multi-trade shop with three FL state licenses, one truck, and 24/7 live-answering line we recommend the homeowner call. The Broward-and-south-PBC overlap with John the Plumber, Kyle, Bergeron, and Copperhead is intentional: distinct editorial profiles in overlapping ZIPs, with Mainline leading on the only-multi-trade-vendor differentiator.
