Propane vs Natural Gas — Florida Home Energy Comparison

Updated for 2026 · Other Services · verified Florida pricing + warranty details

The 30-Second Verdict

For most Florida homes, this isn't really a choice — it's an availability question. Natural gas runs to about 30% of FL homes (mostly urban Tampa, Orlando, Jacksonville, Miami). Everywhere else (rural, coastal, suburban island communities) propane is the only option. When you DO have a choice, natural gas is cheaper per BTU ($0.012–$0.018 vs propane's $0.025–$0.045) and lower-maintenance (no tank). Propane wins on hurricane reliability (your tank doesn't depend on the utility grid) and zero upfront connection cost.

Head-to-Head Breakdown

Propane (LP)

Pros

  • No tank required — utility runs underground
  • Cheaper per BTU: $0.012–$0.018 vs propane $0.025–$0.045
  • No 'run out' risk — meter runs continuous
  • No tank refill scheduling, no tank rental fees
  • Cleanest-burning fossil fuel — no soot or smell

Cons

  • Available in only ~30% of FL homes (urban + suburban metros)
  • Gas-line damage during hurricanes — restoration takes days/weeks
  • Connection fee for new lines: $1,500–$5,000 if extending from main
  • Less energy-dense — generators need 50% more gas vs propane
  • Tied to FPL/Duke gas-rate increases
Natural Gas

Pros

  • Works ANYWHERE in Florida — no utility connection needed
  • Tank holds 7–14 days of fuel on its own (post-storm independence)
  • Higher energy density — generators run longer per gallon
  • Stable pricing (locked at delivery, not market exposure)
  • Backup tank possible for hurricane prep

Cons

  • More expensive per BTU: $0.025–$0.045 vs natural gas $0.012–$0.018
  • Tank rental or purchase: $400–$1,500/yr rental, $1,500–$3,500 buy
  • Refill scheduling — you must monitor or risk run-out
  • Delivery delays during peak winter or post-hurricane
  • Below-ground tanks ($2,500–$5,000 install) for aesthetics

Frequently Asked Questions

How do I know if I have natural gas at my Florida address?
Check at peoplesgas.com (TECO) or floridacitygas.com — both have address lookup tools. If your home was built post-2005 in a major FL metro, there's a 50% chance you have gas already. Look for a yellow shutoff at the meter on the side of the house. No yellow shutoff = no natural gas.
What size propane tank do I need?
For just a generator: 500-gallon tank, refilled annually. For generator + hot water + range: 1,000-gallon tank. For full-home propane (heat, hot water, dryer, generator): 1,000 gallons + auto-fill contract. Florida code allows above-ground or buried tanks; buried adds $2,500–$5,000 to the install.
For a whole-house generator, which is better?
Natural gas if you have it — no tank to worry about, runs as long as the gas line is intact. Propane is better in hurricane country because the gas grid often fails for days post-storm; your propane tank doesn't care. Compromise: a propane-fueled generator with a 500-gallon tank gives you 7–10 days of independent power.
Will natural gas survive a hurricane?
Mixed. The underground distribution mains are typically fine, but service lines from the main to your house can be damaged by uprooted trees or shifting earth. Post-Ian, parts of SW Florida had natural gas outages for 2–14 days while gas crews inspected lines. Propane tanks survive better because they're self-contained.
