June 13, 2024


Finding the perfect air conditioner can be challenging, especially with the wide array of options available. For those looking to stay cool during the hot Canadian summers, wall-mountable ACs offer an excellent solution. These units are designed to be both functional and stylish.

But do you know about their different sizes and capabilities? Whether you’re outfitting a small bedroom, a medium-sized living room, or a large open-plan area, choosing the right size and capacity is essential for optimal comfort and energy savings.

As a reliable HVAC company, we are here to help you out. Let’s discover how you can choose the right-sized AC for your home.

Understanding AC Capacity: BTUs And What They Mean

The cooling capacity of an air conditioner is measured in British Thermal Units (BTUs). Simply put, the higher the BTU rating, the more cooling power the unit has. Here’s a breakdown of what different BTU ratings mean for wall-mountable ACs:

  • 5,000-8,000 BTUs: Suitable for small rooms up to 350 square feet, like bedrooms or home offices.
  • 9,000-12,000 BTUs: Ideal for medium-sized rooms between 350-550 square feet, such as living rooms or large bedrooms.
  • 13,000-18,000 BTUs: Perfect for larger rooms or open-plan areas ranging from 550-1,000 square feet.
  • 19,000 BTUs and above: Best for extra-large spaces, including large living areas, commercial spaces, or entire floors.

When choosing a wall-mountable AC, it’s crucial to match the BTU rating with the size of the room to ensure optimal cooling and energy efficiency.

Small Rooms: Best Wall-Mountable ACs Under 10,000 BTUs

For small rooms, you don’t need a high-capacity unit. An AC with a BTU rating between 5,000 and 8,000 will suffice. These units are compact and cost-effective, providing sufficient cooling for bedrooms, home offices, or small living spaces.

Benefits Of Lower BTU Wall-Mountable ACs

  • Cost Efficiency: Lower BTU units are usually cheaper and consume less electricity, making them budget-friendly.
  • Quieter Operation: These units tend to be quieter, making them perfect for bedrooms or study rooms where noise can be a distraction.
  • Ease of Installation: Installation of these AC units is easy as it requires less wall space and minimal modifications.

When shopping for a wall-mountable AC for a small room, look for features like programmable timers, remote controls, and energy-saving modes to enhance convenience and efficiency.

Medium Rooms: Choosing Wall-Mountable ACs Between 9,000-12,000 BTUs

Medium-sized rooms, such as living rooms or larger bedrooms, require a bit more cooling power. Wall-mountable ACs with BTU ratings between 9,000 and 12,000 are ideal for these spaces.

Features To Look For

  • Advanced Thermostats: Modern wall-mountable ACs often come with advanced thermostat controls, allowing for precise temperature management.
  • Multi-directional Airflow: This feature ensures even cooling throughout the room, eliminating hot spots.
  • Enhanced Filters: Look for units with high-efficiency filters to improve air quality by removing dust, pollen, and other allergens.

By selecting a unit within this BTU range, you can maintain a comfortable environment without overworking the AC, ensuring longevity and efficiency.

Large Rooms: Opting For Wall-Mountable ACs Between 13,000-18,000 BTUs

For larger rooms or open-plan areas, you’ll need a more powerful wall-mountable AC. Units with BTU ratings between 13,000 and 18,000 are designed to cool spaces up to 1,000 square feet.

Advantages Of Higher BTU Wall-Mountable ACs

  • Rapid Cooling: High BTU units can cool large areas quickly, making them ideal for rooms that get hot fast.
  • Consistent Temperature: These units maintain a steady temperature, ensuring comfort throughout the space.
  • Robust Performance: Built for larger spaces, these ACs are durable and capable of handling extended use without compromising performance.

When installing a wall-mountable AC in a large room, ensure it’s placed centrally for maximum efficiency. Additionally, consider models with smart home integration for convenient control via your smartphone.

Extra-Large Spaces: Wall-Mountable ACs With 19,000 BTUs And Above

For extra-large spaces, such as commercial areas, large living spaces, or entire floors, a wall-mountable AC with a BTU rating of 19,000 or more is necessary. These powerful units are designed to handle extensive cooling needs.

Key Features To Consider

  • Smart Controls: Many high-capacity units come with smart controls, allowing you to manage settings via a mobile app or voice assistant.
  • Energy Efficiency: Despite their size, many high BTU units are energy efficient, with features like variable speed compressors and energy-saving modes.
  • Zoned Cooling: Some models offer zoned cooling, enabling you to cool different areas independently for tailored comfort.

Installing a high-capacity wall-mountable AC may require professional installation to ensure optimal performance and energy efficiency. Be sure to consult with an HVAC professional to determine the best placement and installation practices.
