Top products in 💨 Air Conditioners
1. Measure Room Size
Calculate the square footage of the room you want to cool. Measure length x width to get total area:
- Length: 15 feet
- Width: 20 feet
- 15 x 20 = 300 square feet
For multi-room systems, add up the total square footage of all rooms to be cooled.
2. Factor in Room Features
Room features that increase cooling needs:
- Southern or western exposure - Add 10% BTUs
- Heavily shaded - Subtract 10% BTUs
- More than 1 person - Add 600 BTUs per person
- Heat generating appliances and electronics - Add 4,000 BTUs per device
For example, a 300 sq ft room with southern exposure would need 330 BTUs (300 + 10% more).
3. Consider Your Climate
Warmer climates require more cooling capacity. Add this % to your BTU calculation:
- Moderate climates - No adjustment needed
- Hot climates - Add 10% more BTUs
- Very hot climates - Add 20% more BTUs
In a very hot climate, our example 330 BTUs would increase by 20% to 396 BTUs.
4. Select the Right BTU Range
| Room Size (sq ft) | BTUs Needed |
|---|---|
| 100-150 | 5,000 - 6,000 |
| 150-250 | 6,000 - 8,000 |
| 250-300 | 8,000 - 10,000 |
| 300-350 | 10,000 - 12,000 |
For a 330 BTU recommendation, this table shows a 10,000 - 12,000 BTU unit is appropriate.
Properly sizing your AC unit using careful room measurements, climate factors, and BTU guidelines will ensure the best comfort and efficiency.

What Are The Differences Between Ventless And Vented Air Conditioners?
Ventless and vented air conditioners differ in several ways. Here are the main differences between the two types:
Vented air conditioners:
Ventless air conditioners:
Which Type Of Air Conditioner Is More Energy-Efficient, Vented Or Ventless?
Based on the search results, ventless air conditioners are generally more energy-efficient than vented air conditioners. Ventless units use an evaporative process to cool the air, which requires less energy than the refrigerant-based process used by vented units. However, ventless units may not be as effective as vented units in cooling down a room, as they recycle some of the already-cooled air back into the room. It's important to note that the choice between vented and ventless air conditioners ultimately depends on personal preferences and location. In hot and humid climates, vented air conditioners may be more effective at cooling down a room, but they can be more expensive to operate due to their energy consumption. In contrast, ventless air conditioners are easier to install and more energy-efficient, making them a cost-effective and convenient cooling option for those who do not have access to a standard window AC kit.
