The 1.2–1.5 ton category is one of the most common classes for commercial cooling because it balances cooling capacity with manageable size and electrical requirements.
These units typically cover 400–700 sq ft depending on heat load and air circulation.
This page compares the most popular models from each brand in this class so you can choose the one that fits your needs.
What Defines a 1.2–1.5 Ton Spot Cooler
Typical features for this class include:
- Roughly 14,000–18,000 BTU cooling capacity
- 115V or 208–230V power options
- Higher airflow for larger spaces than 1-ton units
- Portable with directional cold-air discharge
- Suitable for mid-sized commercial spaces
- All units use R-454B refrigerant

When to Choose a 1.2–1.5 Ton Spot Cooler
Choose this class when:
- You need to cool 400–700 sq ft
- Heat load is higher than small offices but below large warehouse levels
- You have multiple heat sources (equipment, people)
- Ambient temperatures are elevated
- You need stronger airflow without moving up to 2 tons
If you’re cooling very large spaces or environments with extreme heat loads, consider the 2-ton class next.
