Della Single-Zone Mini Split - Energy-Efficient, Low-Maintenance

A single zone mini split is a type of ductless air conditioning and heating system. It consists of one outdoor compressor unit connected to one indoor air handler. This system is highly efficient and allows precise temperature control for the designated area without the need for ductwork. Single zone mini splits are ideal for spaces like bedrooms, offices, or small apartments where centralized air conditioning is unnecessary.

The labor cost to install a single zone mini split typically ranges from $500 to $2,000, depending on factors such as the length of the refrigerant lines and the location of the unit. Always consult a licensed HVAC professional to get an accurate quote for your specific situation.

Yes, getting a single room AC system can be a smart choice even if you have central air. A single zone mini split is highly efficient for targeting specific rooms that may not be adequately cooled or heated by your central system. For example, if you have a bedroom, office, or sunroom that stays warmer or colder than the rest of the house. Additionally, it can save energy by allowing you to cool or heat only the space you're using, rather than the entire house.

To estimate the BTU needed for a single room AC unit, multiply the room's square footage by 20 BTU per square foot. Adjust this number for factors like ceiling height, insulation, and sun exposure. Here’s a simple guideline for room sizes:

• 150–250 sq. ft.: 6,000–7,000 BTU
• 250–350 sq. ft.: 8,000–9,000 BTU
• 350–450 sq. ft.: 10,000–12,000 BTU
• 450–550 sq. ft.: 12,000–14,000 BTU
• 550–1,000 sq. ft.: 18,000–24,000 BTU
• 1,000–1,500 sq. ft.: 30,000–36,000 BTU

If you live in a small space like a bedroom, home office, studio, or guest room, then single room mini splits are a great choice. They are specifically designed to cool or heat individual rooms efficiently, providing precise temperature control while operating quietly and energy-efficiently.

To choose the right single zone mini split for a small room, consider these factors:

• Room Size: Ensure the BTU capacity matches the room size (e.g., 6,000–9,000 BTU for small rooms).
• Energy Efficiency: Look for a high SEER2 rating (17 or above) to maximize energy savings.
• Noise Levels: Choose a unit with low indoor noise levels (30–45 dBA) for a quiet and comfortable space.
• Features: Prioritize additional features like WiFi remote control, built-in air filtration, and a self-cleaning function for better convenience, air quality, and ease of use.
• Design and Installation: Opt for a unit that blends well with your room’s layout and is easy to install.

For instance, the Della Versa (TL) series 12,000 BTU mini split is an excellent option. It offers a high SEER2 rating of 19, operates quietly (26–41 dBA), and includes features like WiFi remote control, built-in air filtration, and a self-cleaning function, making it perfect for small residential spaces.

The cost of a single room AC system, specifically a mini split, typically ranges from $700 to $2,500 for the unit alone, depending on the BTU capacity, energy efficiency (SEER2 rating), and additional features like WiFi connectivity or air filtration.

For example, a 9,000 BTU mini split suitable for small rooms can cost around $800–$1,200, while a larger 12,000 BTU unit might cost $1,000–$1,500.

When including installation, the total cost of single room AC system ranges from $2,000 to $5,000. It varies due to other factors such as wiring, line length, and wall penetration requirements.

A mini split system is the best type of AC unit for a single room. It offers superior energy efficiency, quiet operation, and precise temperature control compared to window or portable units. Mini splits are ductless, making them ideal for single rooms without requiring extensive modifications or ductwork. They also come with advanced features like WiFi control, self-cleaning, and built-in air filtration, enhancing convenience and air quality.
