⚡ 1. Power Supply Compatibility
-
115V systems plug into a standard household outlet (just like your microwave or TV).
-
230V systems require a dedicated circuit from your electrical panel, often installed by an electrician.
Bottom line:
✅ 115V = plug-and-play in many homes
⚠️ 230V = may need electrical work
🛠️ 2. Installation Cost
-
115V: Lower upfront install cost. No panel upgrades needed in many cases.
-
230V: More complex install. Might require a licensed electrician and possibly a permit.
💪 3. Cooling/Heating Power (BTUs)
-
115V systems usually max out around 9,000–12,000 BTUs.
-
230V systems support higher BTUs (18,000–36,000+), which means:
-
More cooling/heating capacity
-
Better for larger rooms or entire zones
-
⚙️ 4. Energy Efficiency
-
230V systems tend to run more efficiently, especially at higher loads.
-
They draw less amperage for the same power, which can be easier on your home's electrical system.
🏠 5. Best Use Cases
| Voltage | Best For | Limitations |
|---|---|---|
| 115V | Small rooms, retrofits, older homes | Limited capacity, not ideal for whole-house |
| 230V | Whole-home or large room systems | Requires proper electrical setup |
✅ Which Should You Choose?
-
Go with 115V if:
-
You’re installing in a small room (like a bedroom or office)
-
You want quick, easy install with low electrical work
-
-
Go with 230V if:
-
You’re cooling/heating large areas
-
You want higher efficiency & more power
