The 30-Second Verdict
Florida HVAC sizing is its own discipline because of humidity. The old "500 sq ft per ton" rule is wrong here — oversized systems short-cycle and never dehumidify. A properly Manual-J sized Florida home runs ~600–800 sq ft per ton. A 1,500 sq ft home wants a 2-ton (sometimes 2.5); a 2,000 sq ft home wants 3-ton; a 2,500–3,000 sq ft home wants 3.5–4 ton. Trane runs $500–$1,500 more than Rheem at every tonnage; both are excellent systems if installed correctly. Skip any installer who sizes by square footage alone.
Head-to-Head Breakdown
Rheem
Pros
- Lower cost — typically $1,000–$1,500 less than Trane at same tonnage
- Hidden gem: Rheem variable-speed Prestige series outperforms Trane XV20i in FL humidity
- Available through more FL installers
- Better parts availability for repairs
- Lifetime compressor warranty on premium tiers
Cons
- Brand cachet lower than Trane (some buyers prefer 'name brand')
- Outdoor unit looks plain — Trane has better aesthetics
- Quieter on premium tiers; loud on base tier (RA1, RA13)
Trane
Pros
- Strong brand recognition + resale value boost
- XV20i variable-speed is the gold standard for FL humidity control
- Slightly better Florida coastal-coil corrosion resistance
- Best-in-class warranty terms (10 yr compressor standard)
Cons
- 10–25% price premium over Rheem for similar specs
- Fewer FL installers — less competitive pricing
- Premium tier (XV20i) has reliability issues in some 2022–2024 production runs (check serial number)
- Repair parts more expensive when out of warranty

Frequently Asked Questions
How big an AC does my 2,000 sq ft FL home need?
Almost always 3-ton (36,000 BTU). The exception: 2,000 sq ft with vaulted ceilings, west-facing wall of glass, or zero attic insulation might need 3.5-ton. Never trust an installer who quotes 4-ton on a 2,000 sq ft house unless they show you a written Manual-J calc — they're oversizing for an easier sale and you'll get a humid, short-cycling system.
Why is oversizing bad in Florida?
An oversized AC cools the air to the thermostat setpoint too fast — before it can pull humidity out. You end up with a cold, clammy 78°F house at 65% RH instead of a comfortable 78°F at 50% RH. Indoor mold and 'tropical sweat' inside the house are the symptoms. A right-sized unit runs longer cycles and dehumidifies as a side effect.
Is variable-speed worth the extra $2,000?
In Florida — yes, almost always. Variable-speed (also called inverter or modulating) units run at 30–70% capacity most of the time, which means longer dehumidification cycles. You'll pay $1,500–$2,500 more upfront but save $30–$60/month on electric bills and have noticeably better comfort. Payback is typically 5–7 years.
Should I get Trane just for the resale value?
Marginal in Florida. AC age + warranty status matters far more to buyers than brand. A 3-year-old Rheem in great shape sells the house just as well as a 3-year-old Trane. Save the $1,500 and put it toward variable-speed instead.
