Hidden Gas-Line and Venting Costs
A $1,500 commodity quote that skips the gas-line upsize or new vent run still ends up costing $5K once the truck shows up. Real specialists flag that on day one.

The Real Decisions
Tankless Headaches Across the Sunshine State?
You already know you want tankless. The hard part is sizing, brand fit, gas-line work, and finding an installer who actually does this every day.
Brand Choice Paralysis
Rinnai, Navien, Noritz, Rheem, Bosch, and AO Smith each fit different homes. Pick wrong and you pay for the mismatch in GPM, warranty, and energy bills for 20 years.
Repair, Descale, or Replace?
An aging unit could need a $45 filter, a $300 descale, or full replacement. Most general plumbers default to ripping it out, costing thousands you may not need to spend.
Finding a True Tankless Pro
General plumbers install a couple tankless units a month. True specialists install hundreds. The skill gap shows up in venting, combustion analysis, and warranty paperwork.

Local Expertise
What Makes Tankless Different in the Sunshine State
Total Tankless's home state. Hard-water counties across Central Florida demand 6-month descaling cadence, among our most common service calls. Warm year-round inlet temps near 75 degrees Fahrenheit let smaller GPM units deliver more usable hot-water flow than they would in northern states. FPL, Duke Energy Florida, and TECO utility rebate programs apply, and our installers handle hurricane-rated venting plus slab-on-grade install scenarios unique to local construction.
Statewide coverage along I-95, I-75, I-4, and the Florida Turnpike, with vetted installers in every major metro from Miami to Jacksonville.
Local Knowledge Our Installers Carry
- ✓ Florida Building Code (FBC) plumbing chapter
- ✓ FPL energy efficiency rebate
- ✓ Duke Energy Florida tankless rebate
- ✓ TECO conservation program
- ✓ Slab-on-grade installation
- ✓ Hurricane-rated venting

What Homeowners Say
Real reviews from homeowners who trusted us with their tankless installation, repair, and maintenance.
"We were ready to upgrade from a 50-gallon tank to a Navien tankless and got three quotes. Only Total Tankless walked us through the gas-line upsize before we paid for anything. The plumber they sent was clearly tankless-specific. Done in a day."

March 2026
"Our 12-year-old Rinnai started throwing error code 12 every other shower. Total Tankless's tech diagnosed a flame sensor issue over a virtual call, ordered the OEM part, and had us back up in 48 hours. Honest about cost the whole way."
JL
Jennifer L.

"Live in Phoenix, water hardness is brutal. Booked an annual descale and the technician explained why my last DIY flush probably didn't actually move scale through the system. Real expertise, wish I'd called sooner."

"Compared four installers. Total Tankless was the only one that gave me a straight answer on whether condensing was worth the extra cost for my situation. Brand-neutral advice was the difference."
PS

"Switched from electric tank to gas tankless. The conversion was complicated. They handled permits, gas-line upgrade, venting from scratch, and rebate paperwork. Came in within $200 of the virtual estimate."
RK

December 2025
"I had three other plumbers tell me my Noritz needed replacement. Total Tankless found it was a clogged inlet filter, a $45 fix instead of a $5,000 rip-out. That's the brand-neutral expertise this market needs."

FAQs
Common Tankless Questions, Answered
How fast can a vetted local installer reach my home?
Same-day virtual estimate is standard, with most installers booking the in-home visit within 2 to 4 business days. Coverage runs along I-95 and I-75, so Miami, Orlando, Tampa, and Jacksonville homeowners typically see the fastest scheduling.
How often should a tankless unit be descaled in Central Florida?
Every 6 months in hard-water counties, double the once-a-year baseline. Polk, Lake, and parts of Orange County run high enough on calcium that scale starts measurably reducing heat-exchanger efficiency inside 9 months without service.
Which utility rebates stack with the federal IRA credit?
FPL, Duke Energy Florida, and TECO all offer efficiency rebates that combine with the IRA Section 25C tax credit (up to $600). We document eligibility before install so the paperwork is filed on day one, not chased after the fact.
Do your installers handle slab-on-grade conversions and hurricane-rated venting?
Yes. Slab-on-grade installs are routine across the state, and hurricane-rated venting is on every coastal job. Our partner plumbers carry the CFC license and follow the FBC plumbing chapter for vent termination clearances.
How much does a tankless install cost across major metros here?
Most whole-home gas tankless conversions run $5,000 to $9,000 installed, with Miami and Fort Lauderdale slightly higher than Tampa or Jacksonville due to permit and labor cost differences. Tankless-to-tankless replacements run $3,000 to $5,500.
