Quick answer
Most Lithia and FishHawk homes should not choose AC size from square footage alone. A rough screen is 400 to 600 conditioned square feet per ton, and one ton equals 12,000 BTU per hour, so 1.5 ton equals 18,000 BTU/h and roughly screens for 600 to 900 square feet; 2 ton equals 24,000 BTU/h and roughly screens for 800 to 1,200 square feet; 2.5 ton equals 30,000 BTU/h and roughly screens for 1,000 to 1,500 square feet; 3 ton equals 36,000 BTU/h and roughly screens for 1,200 to 1,800 square feet; 3.5 ton equals 42,000 BTU/h and roughly screens for 1,400 to 2,100 square feet; 4 ton equals 48,000 BTU/h and roughly screens for 1,600 to 2,400 square feet; 5 ton equals 60,000 BTU/h and roughly screens for 2,000 to 3,000 square feet. In Lithia and FishHawk, final size still depends on larger planned homes, zoning, upstairs rooms, and airflow balance can make a room-by-room sizing conversation valuable. Use the calculator as a planning screen, then confirm with a field load review before approving equipment.
Local focus: larger planned homes where zoning, airflow, and maintenance planning matter. Example sizing inputs include 33547 and nearby Lithia/FishHawk ZIP codes, FishHawk Ranch, Channing Park, Hawkstone, and homes near FishHawk Boulevard, access routes such as FishHawk Boulevard, Lithia Pinecrest Road, Bell Shoals Road, and Boyette Road, and home patterns like larger planned homes with zoning, upstairs comfort needs, and maintenance planning.
Manual J-style sizing screen
What size AC does this home need?
Enter the home details you know. The tool estimates a cooling-load range, translates it into BTU and tonnage, and shows why the final answer still needs a field load calculation before equipment is selected.
Screening result
- Estimated load
- 46,800 BTU/h
- BTU range
- 41,200 BTU/h to 52,400 BTU/h
- Tonnage range
- 3.4 tons to 4.4 tons
- Local note
- larger planned homes, zoning, upstairs rooms, and airflow balance can make a room-by-room sizing conversation valuable.
This is a Manual J-style planning estimator, not a certified ACCA Manual J load calculation, Manual S equipment selection, permit design, diagnosis, or Air Strike quote.
- Humidity complaints need cycle-length, airflow, drain, thermostat, and fan-mode review; oversizing can make the home feel sticky.
Before selecting tonnage
Field sizing checks before final tonnage
Air Strike treats this calculator as a planning range. Final AC size should be backed by room load, duct delivery, airflow, humidity, and equipment-match checks so the home is not oversized for Tampa Bay moisture control or undersized for peak heat.
- Room-by-room load: additions, west glass, upstairs rooms, and isolated hot rooms can need different airflow than the whole-home average.
- Duct and return capacity: attic leakage, crushed flex, low return air, and high static pressure can make a right-sized system feel wrong.
- Manual S equipment match: the selected model should match sensible and latent capacity needs, not only the nominal ton label.
- Humidity, drain, and thermostat review: cycle length, fan mode, condensate drainage, and thermostat placement matter in Tampa Bay homes.

How much will each AC size cool?
| Size | Capacity | Rough screen |
|---|---|---|
| 1.5 ton | 18,000 BTU/h | 600 to 900 sq ft |
| 2 ton | 24,000 BTU/h | 800 to 1,200 sq ft |
| 2.5 ton | 30,000 BTU/h | 1,000 to 1,500 sq ft |
| 3 ton | 36,000 BTU/h | 1,200 to 1,800 sq ft |
| 3.5 ton | 42,000 BTU/h | 1,400 to 2,100 sq ft |
| 4 ton | 48,000 BTU/h | 1,600 to 2,400 sq ft |
| 5 ton | 60,000 BTU/h | 2,000 to 3,000 sq ft |
The chart uses the common 400 to 600 square feet per ton screen. Tampa Bay homes can move outside that range because of ducts, sun, attic heat, air leakage, additions, occupants, and humidity goals.

Quick AC size chart for Lithia and FishHawk
For Lithia and FishHawk planning, 1.5 ton equals 18,000 BTU/h and roughly screens for 600 to 900 square feet; 2 ton equals 24,000 BTU/h and roughly screens for 800 to 1,200 square feet; 2.5 ton equals 30,000 BTU/h and roughly screens for 1,000 to 1,500 square feet; 3 ton equals 36,000 BTU/h and roughly screens for 1,200 to 1,800 square feet; 3.5 ton equals 42,000 BTU/h and roughly screens for 1,400 to 2,100 square feet; 4 ton equals 48,000 BTU/h and roughly screens for 1,600 to 2,400 square feet; 5 ton equals 60,000 BTU/h and roughly screens for 2,000 to 3,000 square feet. This is the common 400 to 600 square feet per ton screen. It is useful for understanding BTUs, but it is not a final size because larger planned homes, zoning, upstairs rooms, and airflow balance can make a room-by-room sizing conversation valuable.
Manual J-style factors that change Lithia and FishHawk sizing
A Lithia and FishHawk sizing review should check conditioned square footage, ceiling height, window area and direction, insulation, air leakage, attic heat, duct location, return-air path, room additions, occupancy, appliance loads, thermostat placement, and humidity complaints. Lithia and FishHawk installation planning should confirm system count, zoning, upstairs airflow, attic access, return sizing, and whether one failing system affects the whole comfort plan.
How much will each AC size cool in Lithia and FishHawk?
A 2 ton AC is 24,000 BTU/h and roughly screens near 800 to 1,200 square feet. A 3 ton AC is 36,000 BTU/h and roughly screens near 1,200 to 1,800 square feet. A 4 ton AC is 48,000 BTU/h and roughly screens near 1,600 to 2,400 square feet. A 5 ton AC is 60,000 BTU/h and roughly screens near 2,000 to 3,000 square feet. Lithia and FishHawk homes can fall outside those ranges when ducts, sun, attic heat, additions, or humidity load are unusual.
Why bigger AC can be wrong for Lithia and FishHawk humidity
Bigger equipment can cool the thermostat before the system runs long enough to remove moisture. That matters in Lithia and FishHawk because sticky rooms, short cycling, and uneven comfort can come from duct delivery, low return air, thermostat placement, fan settings, or an oversized system. Increasing tonnage without fixing airflow can leave the same comfort problem in place.
What the final sizing visit should verify in Lithia and FishHawk
Before final sizing, the visit should verify the old system size, indoor and outdoor equipment match, duct and return capacity, drain routing, electrical scope, filter location, thermostat placement, equipment access, and larger floor plans, multiple systems, zoning controls, upstairs heat gain, and community access can affect replacement planning. Photos of the air handler, outdoor unit, filter rack, thermostat, hot rooms, and visible duct access can help the first conversation.
Use the calculator for Lithia and FishHawk replacement planning
The calculator on this page gives a load range and tonnage screen for a Lithia and FishHawk home. Treat the result as a question list: why the load moved, which rooms are driving it, whether ducts can deliver the air, and whether the current system short cycles, runs constantly, or leaves humidity behind. Final equipment should still follow field review and Manual J/Manual S guidance.
Homeowner questions
FAQ
What size AC does a Lithia and FishHawk home need?
A Lithia and FishHawk home needs a size based on load, not square footage alone. A 400 to 600 square feet per ton screen can estimate BTUs, but Lithia and FishHawk homes still need review for insulation, windows, attic heat, ducts, ceiling height, additions, occupants, humidity, and room comfort before equipment is selected.
How many square feet will a 3 ton AC cool in Lithia and FishHawk?
A 3 ton AC is 36,000 BTU per hour and often screens around 1,200 to 1,800 conditioned square feet. In Lithia and FishHawk, that range can move when duct leakage, west-facing glass, high ceilings, older insulation, additions, or humidity complaints change the actual load.
Is a 4 ton AC too big for a Lithia and FishHawk home?
A 4 ton AC is 48,000 BTU per hour and often screens around 1,600 to 2,400 square feet, but it can be too big or too small depending on the home. Oversizing can hurt humidity control, while undersizing or poor airflow can leave the home hot. Use load review, not tonnage alone.
Should I replace my Lithia and FishHawk AC with the same size I have now?
Not automatically. The old size may be reasonable, but additions, window changes, insulation, duct leakage, thermostat placement, hot rooms, humidity complaints, and equipment mismatch can change the right answer. A Lithia and FishHawk replacement review should explain why the proposed size fits the home now.
Can the calculator replace a Manual J for Lithia and FishHawk AC replacement?
No. The calculator is a planning screen, not a certified Manual J load calculation or Manual S equipment selection. Use it to prepare better questions, then have the home reviewed for construction details, ducts, windows, humidity, airflow, access, and installed equipment before approving replacement size.
