Bosch vs Gree – Which Is Better?
Published May 24, 2022 – Updated for 2025
When a client recently asked me, “Bosch vs Gree?”, it struck me as a great question for a blog post.
If you’ve read any of my previous articles or reviews, you know I’m a big fan of offering multiple options to our clients—not giving them an ultimatum. We carry both Bosch and Gree for a reason. Both make great inverter-driven heat pumps, both have pros and cons, and both are solid choices depending on the situation.
So, let’s take a look at Bosch vs Gree from someone who’s installed a whole lot of both right here in the Phoenix area.
Bosch vs Gree – Who Are They?
Quick Comparison
| Brand | Founded | Fun Fact | Local Availability |
|---|---|---|---|
| Bosch | 1886 (heat pumps for 47 yrs) | One of the largest privately held companies in the world | Widely sold in AZ – not always installed by trained techs |
| Gree | 1991 | Manufactures 1 in 3 air conditioners worldwide | Limited dealer network – better odds of pro installation |
Bosch is a household name—tools, appliances, and HVAC equipment included. Their heat pumps are quiet, efficient, and easy to use without needing proprietary thermostats or controls.
Gree might be less familiar in the U.S., but globally they’re a giant. They manufacture systems for several “name brand” companies and have quickly become a go-to option for high-performance HVAC systems here in Arizona.
Gree Flexx vs Bosch IDS – Our Real-World Experience
We were the first contractor in Arizona to install a Bosch inverter heat pump, and we’ve since installed hundreds across Phoenix and the East Valley. When Gree’s Flexx system came to market, we were one of the first to get hands-on with it too.
We don’t just read spec sheets—we see how these units perform in real homes, with real homeowners, in real Phoenix summer heat.
Feature Comparison
| Feature | Bosch IDS | Gree Flexx |
|---|---|---|
| Compressor Type | Inverter-driven, variable-speed | Inverter-driven, variable-speed |
| Noise Level | Quiet | Ultra-quiet |
| Energy Efficiency | Very high | Very high |
| Smart Thermostat Required | No proprietary thermostat needed | No proprietary thermostat needed |
| Price Range (in Phoenix) | Mid-range (Low when compared to other variable speed inverters in its weight class) | Lower than Bosch |
| Installer Access | Sold widely (some untrained) | Select dealers only (trained pros) |
| Unit Footprint | Standard footprint, top discharge | Side-discharge, compact footprint |
| Warranty | 10 years parts & compressor | 10 years parts & compressor* |
*When installed by a Gree Select Dealer like Magic Touch Mechanical. Otherwise, 5 year parts.
What Can Go Wrong?
Bosch
We’ve seen plenty of Bosch heat pumps installed poorly by untrained or under-qualified contractors. Why? Bosch is available through a lot of suppliers, and not every installer is factory-trained unfortunately. Some suppliers will sell to anyone with a contractors license and a pulse. This can result in poor outcomes for the end user as install and setting make all the difference – especially on this high-tech equipment.
If ductwork, sizing, refrigerant charge, or airflow are off—it doesn’t matter how good the equipment is. The performance suffers, and unfortunately, we’ve been called to fix quite a few of these over the years.
Gree
The Gree Flexx is compact and efficient, but it needs breathing room. The side-discharge design means airflow clearance is a must. We measure and plan for this during the installation process—so it’s never a problem.
Right now, both Bosch and Gree’s lineup are limited to top-tier variable-speed systems. If you’re looking for a basic single-stage or mid-range system, other brands have more flexibility. But if you’re going high-efficiency, both are serious contenders.
So Which Is Better?
Let’s simplify it:
- Looking for a household name with a proven track record? → Bosch.
- Want top-tier tech with a lower price tag? → Gree (but proceed with caution).
- Live in Mesa, Chandler, Gilbert or nearby? → We install both.
In our experience, both brands perform extremely well when installed correctly. We carry Bosch and Gree because we trust them, and our clients love them. We don’t push—we guide. Our job is to help you choose what’s best for your home, your goals, and your budget.
Update Summer 2025 – Important Update Gree Flexx Potential Failure Alert
If you’ve read my previous review you know I own a Gree mini split in my own home – and it’s fantastic. We’ve installed many Gree mini splits in hundreds of Phoenix homes and our clients love them!
The Gree Flexx I installed in my mothers Chandler, AZ home has worked flawlessly for almost 3 years. We have approximately 100 of them installed in homes all over the valley – all working great. HOWEVER, I’m advising people to wait until Gree addresses a design flaw in their Gree Flexx condenser before choosing one.
We’ve seen a number of cases where a non-essential component fails, releasing the system’s refrigerant. We’ve made Gree aware of the situation and are told it’s being corrected but until we see it is corrected my advice is to consider Bosch as the next least expensive inverter on the market.
TO BE CLEAR: This “hold” advice only applies to the Gree Flexx model. The failing component is only in the Flexx model. I highly recommend other Gree products, especially their mini split lines which have a flawless track record and almost non-existent failure rate. Again, I own one personally.
