How is AC Fit Check different from a generic AC size calculator?

AC Fit Check starts with a specific unit and its actual specifications, then checks whether that exact unit fits your room.

Which values do I need from the AC label?

Cooling Capacity or BTU/h and Input Power in watts are the key values, plus compressor type and optional annual energy use.

Does this replace a professional HVAC load calculation?

No. It is a first-pass check before purchase, not an engineering design.

Specific-unit check, not a generic BTU calculator

Is this exact AC model a good fit for your room?

Start with the AC unit in front of you: enter its model name and copy Cooling Capacity and Input Power from the product label, then add the room conditions. The result checks that exact unit and returns PASS / BORDERLINE / FAIL.

✓We do not require a brand and we do not store your inputs. All calculations run in your browser.

Enter the specs of the model you are considering

This is not a “how many BTU do I need?” tool. Enter a specific unit from a store or quote, then test it against your room using the values printed in its specifications.

Faster input

Paste the AC specifications instead of copying every number manually

Copy specification text from a product page or label. Parsing stays in your browser; we try to extract the model, Cooling Capacity, Input Power, annual energy use and compressor type.

Specification text

What can the parser extract?

Common English and Arabic formats, including BTU/h or cooling kW, Input/Rated Power in W or kW, annual kWh and inverter type. Always verify extracted values against the source.

1) Room and conditions

City / climateA small internal climate adjustment, documented in the method.

Usual occupants

Windows and glazing

Roof exposed to direct sun / top floor Kitchen or high heat-generating equipment in the room

2) Specifications of the selected model

Model name / number (optional)The result link helps you remember which unit you tested. We do not look up the model in a database or send its name to a server.

Cooling Capacity (BTU/h)Example: 12000, 18000 or 24000. This is not electrical input power.

Input Power (W)Copy it from the product label or official specifications. Leave it blank if unknown.

Compressor type

Annual energy use on the energy label (kWh/year)If it appears on the official label, we keep it as published for model comparison and do not turn it into a bill.

BTU ≠ wattsCooling capacity and electrical input are kept separate so we do not invent an electricity cost.

Start with the product labelWe use the model’s actual BTU and Input Power rather than guessing electrical use from capacity.

Inputs are not storedThe calculation runs locally in your browser. A share URL is created only when you request it.

Before you click “buy”

These guides explain which values to copy from a product page or energy label and when the calculator result is not enough.

Product label

How do you find BTU and watts without mixing them up?

The difference between Cooling Capacity and Input Power and what matters before purchase.

Read the guide →Model check

How do you check a specific 18,000 BTU model?

Copy the values from the product page and test the unit itself instead of relying on a generic room-size chart.

Read the guide →Specifications

Is the word Inverter enough to judge a model?

No. Check capacity, electrical input and the official label together.

Need to size a portable dehumidifier?

Calculate capacity, kWh and running cost from room conditions and electrical inputs.

What makes AC Fit Check different?

AC Fit Check does not start with a generic “how many BTU?” or “what will my bill be?” question. It starts with a specific real model in front of you and asks whether that unit’s specifications fit this room.

That is why we ask for Cooling Capacity, Input Power and compressor type from the product label and use room conditions only as a comparison reference. For whole-home sizing, multiple rooms or tariff/cost planning, use Saudi Home Energy instead.

Common questions

Is AC Fit Check a generic AC size calculator?

No. The goal is to check a specific model after you find a unit you may buy.

Which values should I copy from the product page?

Cooling Capacity or BTU/h, Input Power in watts and compressor type. If the energy label publishes annual consumption, you can add that too.

Is BTU the same as electricity use?

No. BTU/h describes cooling capacity while Input Power describes electrical power.

Does the result replace a professional HVAC load calculation?

No. This is a first-pass pre-purchase check. Large or unusual spaces need a more detailed engineering load calculation.
