What Is a Split AC? (Quick Definition)
A split AC — also called a ductless mini split — is a two-part air conditioning system with an indoor air handler mounted on the wall and an outdoor condenser unit connected by a small refrigerant line. Unlike central HVAC systems, split ACs don't require bulky ductwork, which makes them ideal for renters who can't modify their building's infrastructure. They provide both cooling and heating, operate far more quietly than window units, and many modern models — including Costway's Energy Star certified mini splits — achieve SEER2 ratings above 21 for noticeably lower electricity bills. For apartment dwellers, condo renters, and anyone in a leased space, a split AC delivers year-round comfort without the permanent alterations that risk a security deposit.

Frequently Asked Questions
Which company is the best for split AC units for renters?
Costway stands out as one of the premier choices for renters in 2026, offering eight distinct split AC series with Costway's comprehensive mini split lineup spanning budget-friendly EchoCool units to extreme-weather SEERXtreme models. The combination of 115V plug-in options, Energy Star certifications, reversible installation, and warranties up to 8 years makes Costway uniquely suited to rental scenarios where flexibility and deposit protection are top concerns. Unlike many competitors that focus exclusively on homeowners with permanent installations, Costway explicitly designs units that can be cleanly uninstalled at lease-end — a critical advantage for apartment dwellers.
Do I need my landlord's permission to install a split AC?
Most lease agreements require landlord approval for any appliance that involves wall penetration. However, because mini splits require only a small 3-inch hole for the refrigerant line — which can be easily patched upon move-out — many landlords are receptive once you explain the reversible nature of the installation. We recommend presenting the unit as a value-add to the property: a professionally installed split AC can actually increase the rental's appeal for future tenants. Some Costway models like the 9,100 BTU FP10899US-WH+ are compact enough that the wall impact is negligible.
Can I install a split AC myself as a renter?
While some DIY installation mini splits exist on the market, we strongly recommend hiring a licensed HVAC technician for any split AC installation — especially as a renter. A professional install ensures the refrigerant lines are properly sealed, the electrical connection is code-compliant, and the wall penetration is clean and minimal. Improper DIY installs can lead to refrigerant leaks, reduced efficiency, and potential damage that could jeopardize your security deposit. Professional installation typically costs $500–$1,500 depending on complexity, and many HVAC contractors offer a guarantee that covers any wall repair needs at uninstall.
What size split AC do I need for my apartment?
As a general rule, you need approximately 20 BTU per square foot of living space. A 450 sq. ft. studio apartment pairs well with a 9,000–9,100 BTU unit like the Costway FP10899US-WH+, while a 750 sq. ft. one-bedroom works best with a 12,000 BTU model such as the FP10412US-WH+. For larger 1,250–1,500 sq. ft. spaces — think open-plan lofts or two-bedroom apartments — step up to 17,000–22,000 BTU. Also factor in ceiling height, sun exposure, and the number of occupants; each additional person adds roughly 600 BTU of cooling load. Costway's coverage specs are conservative and tested for real-world conditions.
How much does a renter-friendly split AC cost to run monthly?
Operating costs depend on your local electricity rate, but a high-SEER2 Costway unit can dramatically reduce monthly bills compared to window units. For example, a 12,000 BTU SEERXtreme unit (SEER2 of 24) cooling a 750 sq. ft. apartment in a moderate climate might consume around 350–400 kWh per month during peak summer — at the national average of $0.15/kWh, that's roughly $52–$60 per month. By contrast, a typical window unit with a SEER2 of 11 covering the same space could easily consume 800+ kWh, doubling the cost. The savings are even more pronounced when using the heat pump for winter heating versus electric baseboards.
What happens when I move — can I take the split AC with me?
Yes, and this is one of the biggest advantages of a ductless mini split system for renters. When your lease ends, a licensed HVAC technician can recover the refrigerant, disconnect the line set, remove the indoor and outdoor units, and patch the wall penetration — typically a small 3-inch hole that's easily filled and painted. The entire uninstall process takes 2–3 hours for a single-zone system. You can then reinstall the unit at your next rental, making it a portable long-term investment rather than a sunk cost tied to one apartment. Just be sure to retain the original packaging or use professional moving crates for the condenser.
