Dual Mitsubishi mini-split outdoor units professionally installed

Building townhomes in the Dallas-Fort Worth area presents unique challenges, especially when it comes to HVAC systems. Shared walls, varying unit sizes, and the desire for individual comfort create a complex puzzle. But what if there was a single solution that addressed nearly all of these pain points? I believe there is: multi-zone mini-split systems, particularly ducted versions, are not just a good choice—they’re the best choice, and frankly, what I wish every townhome developer would implement.

As Truficient Energy Solutions, we’ve seen firsthand the issues that arise from traditional HVAC setups in townhomes. We serve residential and commercial clients across the DFW metroplex, and we’re passionate about finding the right solutions for every project. This isn’t just about selling equipment; it’s about creating comfortable, efficient, and valuable living spaces.

This blog post is aimed at townhome developers—the individuals and companies who are shaping the DFW landscape. You’re juggling budgets, building codes, and buyer expectations. You need HVAC solutions that work, not just on paper, but in real-world applications.

The Problem with Traditional HVAC in Townhomes

Many developers opt for a single, central HVAC unit with zoned dampers to control airflow to different floors. On the surface, this approach seems cost-effective. However, it often leads to several problems:

• Uneven Temperatures: Inconsistent airflow due to static pressure and turbulence means some areas are too hot, while others are too cold. This is especially prevalent in multi-story townhomes.
• Increased Noise: Traditional systems with extensive ductwork can generate significant noise, disrupting the peace and quiet of residents, especially with shared walls.
• Reduced Efficiency: Air loss through ductwork and inefficient zoning dampers reduces overall system efficiency, leading to higher energy bills. Variable speed systems can mitigate this but are not always used.
• Limited Control: Residents have limited control over their individual comfort, leading to disputes and dissatisfaction.

The Multi-Zone Mini-Split Advantage

Multi-zone mini-split systems offer a superior alternative, addressing the core challenges of townhome HVAC. Here’s why they’re the ideal solution:

• Individual Unit Control: Each zone (typically each floor in a townhome) has its own dedicated air handler, providing precise temperature control and personalized comfort for residents. This is a huge selling point for potential buyers.
• Minimized Noise and Vibration: Ductless or short-duct systems significantly reduce noise and vibration transmission between units, creating a more peaceful living environment. Ducted systems can also be engineered to reduce noise better than traditional systems.
• Optimized Space Utilization: With smaller ductwork or ductless options, multi-zone systems free up valuable space that can be used for closets, storage, or other amenities. This is a major advantage in space-constrained townhomes.
• Enhanced Energy Efficiency: Each zone operates independently, allowing for greater energy savings. Residents can heat or cool only the areas they’re using, reducing overall energy consumption.
• Meeting Building Codes and Fire Safety Regulations: Multi-zone mini-split systems can be designed to comply with all relevant building codes, fire safety regulations, and party wall requirements.
• Increased Resale Value: The enhanced comfort, efficiency, and control offered by multi-zone mini-splits make townhomes more attractive to buyers, increasing their resale value.

Ducted or Ductless? The Townhome Preference

While ductless mini-splits are a viable option, many homeowners in the US prefer the more traditional look and feel of ducted systems. Fortunately, multi-zone mini-splits offer both options. For townhomes, a ducted system is often the preferred choice, allowing for discreet installation and integration with standard vents and registers.

My Wish: A Zone for Every Floor

My personal recommendation for townhome developers is to implement a true zone for each floor. This means a separate air handler for each level, ensuring optimal comfort and control. I understand the desire to save a few thousand dollars per system by using a single central unit with zoned dampers. However, the long-term benefits of multi-zone mini-splits—increased resident satisfaction, lower energy bills, and higher resale value—far outweigh the initial cost difference.

The Perfect Air Handler: Mitsubishi’s SEZ and PEAD Models

For ducted multi-zone systems in townhomes, Mitsubishi Electric’s SEZ and PEAD ceiling-concealed models are an excellent choice. These units offer:

• Ceiling-Concealed Design: Discreet installation with short-run ductwork.
• Wide Static Pressure Range: Suitable for various ductwork configurations.
• Built-in Condensate Lift Mechanism: Simplifies installation and drainage.
• Auto Fan Speed Mode: Provides quiet and efficient operation.
• Optional Filter Boxes: Improve air quality and simplify maintenance.
• Advanced Control Options: Including app integration (Kumo Cloud), wired and wireless controllers, and third-party interface options.

Key Features and Specifications (Mitsubishi SEZ/PEAD Example):

• Cooling/Heating Capacity: 36,000 BTU/H
• Voltage: 208/230 V, single-phase
• Static Pressure: 0.14–0.60 in. WG
• Control Options: Kumo Cloud app, wired/wireless controllers, various interfaces
• Accessories: Filter boxes, condensate pumps, linesets

(Note: Specific features and specifications may vary depending on the exact model and configuration.)

Freeing Up Space and Enhancing Design

Using ducted multi-zone units can also free up valuable space within the townhome. By eliminating large duct runs and traditional furnace closets, developers can create more usable living space, such as larger closets or additional storage. Recessed ceiling units can be installed if the truss system is designed to accommodate them, and the ductwork can be run through the ceiling, further maximizing space. This is especially beneficial in basement areas, where a ceiling-recessed or wall-mounted unit can eliminate the need for extensive ductwork.

A Better Product for the Home Buyer

Ultimately, investing in multi-zone mini-split systems is an investment in the quality of your product. By providing greater control of temperature and airflow, you’re creating a more comfortable and desirable living environment for your buyers. This translates to happier residents, fewer complaints, and a stronger reputation for your company.

Communicating the Value

When discussing HVAC options with townhome developers, it’s important to emphasize the long-term value and cost-effectiveness of multi-zone mini-splits. Highlight the following:

• Reduced Energy Costs: Lower utility bills for residents.
• Increased Resale Value: More attractive to buyers.
• Enhanced Comfort and Control: Personalized comfort for each zone.
• Minimized Noise and Vibration: A quieter and more peaceful living environment.
• Space Optimization: More usable living space within the townhome.

By focusing on these key benefits, you can demonstrate the clear advantages of multi-zone mini-split systems and help developers make informed decisions that benefit both their bottom line and the satisfaction of their future residents. If you’re developing townhomes in the Dallas-Fort Worth area, consider this: multi-zone mini-splits aren’t just a good option—they’re the smart option.
