The Real Cost of Manual Mini-Split Configuration
⏱️ Hours Wasted on Compatibility Checking
The Manual Process: Opening multiple PDF compatibility charts, cross-referencing outdoor units with indoor units, checking distribution box requirements, validating port capacities, and hoping you didn't miss anything.
Our Solution: Instant validation against thousands of component combinations. Select your equipment and get immediate compatibility confirmation. What took hours now takes seconds.
The Impact: At typical contractor billing rates ($75-125/hour), that's $150-375 in lost time per project. Over 10 projects per month, you're losing $1,500-3,750 in billable time.
💸 Costly Equipment Ordering Mistakes
The Problem: Ordering a distribution box that's incompatible with your outdoor unit. Discovering indoor units that exceed port capacity. Missing BTU limitations. Return shipping, reorder delays, angry customers.
Our Solution: Real-time distribution box validation. Automatic port capacity checking. BTU aggregation logic that prevents over-specification. Impossible to configure an incompatible system.
The Impact: One prevented mistake pays for years of Pro subscription. Return shipping ($50-150), restocking fees, customer wait time (3-5 days), damaged credibility—all eliminated.
📋 Scattered Technical Specifications

Frequently Asked Questions
Everything you need to know about using MiniSplit Match
How long does it take to configure a system?
2-3 minutes for most systems. Simple configurations (1-3 zones) take about 1 minute. Complex multi-zone systems (4-8 zones) typically take 2-3 minutes. Our tool guides you through brand selection, zone configuration, and equipment selection with real-time compatibility checking at each step.
Is the configurator really free?
Yes. The free plan includes 3 system configurations per month, 1 saved project, compatibility checking, and our simple sizing calculator. It's perfect for homeowners, DIY installers, and contractors evaluating the tool. Pro users ($29/month) get unlimited configurations, AHRI ratings, technical specifications, equipment manuals, and unlimited saved projects.
How accurate is the sizing calculator?
Our sizing calculator provides estimates within 10-15% accuracy for typical residential applications—close enough for equipment selection in most cases. It considers climate zone, construction era, room type, square footage, and ceiling height. For critical commercial applications or unusual scenarios, we recommend professional load calculations, but our calculator works well for the majority of residential projects.
Does it work for DIY installations?
The configurator works for anyone—DIY homeowners and professional contractors alike. It helps you select compatible equipment and understand specifications. However, actual installation requires licensed HVAC technicians for refrigerant work, electrical connections, and code compliance. Many DIYers use our tool to select equipment, then hire professionals for installation.
What brands do you support?
Currently Fujitsu, LG, and Mitsubishi Electric—three of the most popular and widely-available mini-split manufacturers. Our database includes current and recent equipment models for each brand. We're continuously validating additional brands and will expand our coverage over time.
How current is your equipment database?
We update our equipment database regularly as manufacturers release new models. Our database includes current product lines plus recent models (typically 2-3 years back) that are still commonly available. When manufacturers discontinue equipment or release major updates, we validate and add new models within weeks of release.
What if I need more than 8 zones?
Most residential and light commercial projects use 1-8 zones, which our tool fully supports. For larger projects requiring 9+ zones, you'll typically need multiple outdoor units. Contact us to discuss your specific requirements—we can help you break complex projects into multiple systems that work together.
Can I use this for commercial projects?
Yes. Many contractors use MiniSplit Match for light commercial applications (offices, restaurants, retail spaces, small warehouses). Our tool handles the same equipment commercial contractors use. For large commercial projects with special requirements, our Pro plan provides the detailed specifications and AHRI ratings needed for professional submissions.
Do you include line set requirements?
Yes. The tool considers maximum line length and elevation changes when recommending equipment. Each brand has specific line length limitations that affect system performance. While we don't calculate exact line set sizing (that depends on installation specifics), we ensure recommended equipment supports your configuration.
Can I export specifications for quotes?
Pro plan users can export complete system specifications including model numbers, capacities, AHRI ratings, and technical details. This makes creating professional quotes simple—you get all the information needed for accurate pricing and customer presentations in an easy-to-use format.
What about accessories like thermostats and controllers?
Our tool focuses on core system components (outdoor units, indoor units, distribution boxes). Most modern mini-splits include wireless remote controls. For advanced controllers, thermostats, or smart home integration accessories, check with your chosen brand's specifications or authorized dealers after selecting your base system.
How do you handle distribution box requirements?
Automatically. When you configure a multi-zone system, our engine determines if distribution boxes are required based on brand-specific rules, zone count, and capacity. We then validate port capacities (each port supports specific BTU ranges like 9k, 12k, 18k) to ensure your indoor units don't exceed limits. This prevents the most common compatibility mistake.
Can I compare systems across different brands?
Not directly within one configuration, but you can easily run separate configurations for each brand (each counts as one configuration toward your monthly limit). This lets you compare Fujitsu vs LG vs Mitsubishi options for the same project. Many contractors do this to provide customers with multiple brand options and price points.
What if I find a compatibility error?
Our compatibility engine is built on manufacturer specifications and validated extensively, but if you encounter an error, please contact us immediately with the specific configuration details. We take accuracy seriously and will investigate and correct any issues promptly. Your feedback helps improve the tool for everyone.
Do you offer technical support?
Yes. Free plan users can contact us via email for configuration questions or technical issues. Pro plan users receive priority support with faster response times. We're here to help you successfully configure systems and understand the tool's features.
