If you've been hunting for a high-performing, energy-efficient HVAC system for your home, garage, or workspace, chances are you’ve come across the Goodman name more than once. And for good reason. Goodman has earned its stripes as a leading manufacturer of dependable, cost-effective HVAC solutions that just get the job done. But here’s the kicker—when it comes to choosing the right Goodman mini split, especially within the E Series lineup, the options can get a little overwhelming.
In this guide, we’ll take a deep dive into the world of Goodman E Series mini splits, with a particular focus on models like the Goodman 12000 BTU mini split, the Goodman 9000 BTU mini split, and the ever-popular Goodman mini split 12 000 BTU unit. Whether you’re outfitting a small apartment, upgrading your home office, or need zoned control for a garage workshop, we’ll help you match the right unit to your space. We'll also compare these mini splits to traditional HVAC systems and highlight the advantages of bundling with a larger central system—like the one featured in the Goodman 3 Ton 14.5 SEER2 R-32 Bundle.
What Sets the Goodman E Series Apart?
Let’s start with the basics: the Goodman E Series is designed to provide efficient, reliable cooling and heating for residential and light commercial applications. Unlike a central HVAC system, mini splits are ductless. That means lower installation costs, greater zoning flexibility, and minimal disruption to your home’s layout.
Goodman’s E Series mini splits are inverter-driven systems, which allow them to maintain room temperature with precise control and minimal energy use. Instead of blasting cold air when the room gets warm and then turning off, these systems gradually adjust their output—like cruise control for your home’s comfort.
The Technology Behind It
Each unit comes equipped with high-efficiency compressors, intelligent defrost technology, and washable filters. Most importantly, Goodman E Series mini splits use R-32 refrigerant, a more eco-friendly option that has a lower Global Warming Potential (GWP) compared to R-410A. According to Daikin, transitioning to low-GWP refrigerants is a major step toward greener HVAC solutions.
Understanding BTUs: Why Size Matters
You’ve likely seen BTU ratings on mini splits—9000 BTU, 12000 BTU, and so on. But what do these numbers mean in real life?
BTU stands for British Thermal Unit, and it measures the amount of energy needed to cool or heat a space. A Goodman 9000 BTU mini split is typically ideal for a room up to 400 square feet. That makes it perfect for spaces like bedrooms, home offices, or sunrooms.
On the other hand, a Goodman 12000 BTU mini split or Goodman mini split 12 000 BTU is better suited for areas between 400 to 550 square feet—think larger living rooms or open-concept kitchens. Choosing the wrong size unit can lead to inefficiencies, uncomfortable temperature fluctuations, or excessive energy bills.

How Goodman Mini Splits Compare to Traditional HVAC
Let’s face it—central HVAC systems still dominate most homes, and for large spaces, they make sense. But ductless mini splits are gaining serious traction. Why?
-
No ductwork needed
-
Quicker installation
-
Better zoning control
-
Lower energy loss
If you’ve ever cooled or heated a room that nobody uses, you know what I’m talking about. Mini splits let you avoid that waste, which adds up in savings over time. According to Green Building Advisor, well-installed mini splits can outperform central systems in terms of energy efficiency, especially in moderate climates.
Where Central Systems Still Win: Large Homes and Whole-House Comfort
That said, there’s a ceiling to what mini splits can do. If you’re looking to control temps in a large home or multi-level property, a centralized system like the one in the Goodman 3 Ton 14.5 SEER2 R-32 Bundle offers better bang for your buck—especially when paired with high-performance insulation and smart thermostats.
This 3-ton system is perfect for homes around 1500–1800 sq ft, offering robust cooling with the eco-friendliness of R-32 refrigerant. It also integrates beautifully with existing ductwork, making it a smart long-term investment if your home already has a central system in place.
Installation Tips: DIY or Hire a Pro?
While some mini split models are sold as “DIY-friendly,” you should still have a licensed HVAC technician handle the refrigerant lines and final hookups. Why? Because a minor error—like improper line flushing—can lead to system damage or refrigerant leaks.
Many homeowners who attempt DIY installs without full knowledge of vacuuming linesets or setting up the condensate drain end up calling a professional anyway. Avoid the hassle—get it done right the first time.
