4 units ranked by real SACC, the number that matters, not the BTU figure printed biggest on the box. Includes the one pick that actually works in a tight condo window.
Toronto’s condo AC-assistance program has already handed out about 1,500 free units to residents this year. If you check SACC, not BTU, before you buy, you’ll actually get the cooling the box promises instead of a number inflated by lab conditions no real room matches.
The BTU number on the box is inflated. Check SACC (Seasonal Adjusted Cooling Capacity) instead.

Every portable AC lists a BTU number based on lab conditions with the hose disconnected. In 2017 the DOE mandated a second, more honest figure: SACC (Seasonal Adjusted Cooling Capacity), tested with the hose attached like you’d actually run it. The gap between the two numbers varies a lot by brand, sometimes only 15% (like the Midea here), sometimes closer to 40% (like the DeLonghi). A “14,000 BTU” unit that’s really an 8,600 SACC unit is meaningfully weaker than a “14,000 BTU” unit that’s a genuine 12,000 SACC.
Nobody covers the condo/rental window-venting problem alongside real product picks. Most portable AC guides ignore that a lot of Canadian apartments have crank, casement, or narrow sliding windows that standard venting kits don’t fit well.
Sizing matters more than the brand when picking what apartments and condos actually need. A rough but honest starting point: about 20 BTU (SACC) per square foot for a normal room, more if it gets strong afternoon sun.
This is a starting estimate, not an exact engineering calculation. Ceiling height, insulation, and how many people/electronics are in the room all shift the real number.

Every standard portable AC ships with a window venting kit built for a double-hung or sliding window with real width to work with. Toronto and Vancouver strata rules, older casement windows, and narrow condo openings are where most kits struggle.
The Dreo’s 17″-53″ adjustable panel is the best product-level answer we found. It’s still a product-level answer, not a universal fix. A true crank or fixed-pane window with no real opening doesn’t have a portable-AC solution at all beyond a custom-built acrylic or plywood insert cut to your specific window, which several real buyers online resorted to when no off-the-shelf kit fit.
One more thing before you buy: your pick still has to fit the window. Check your window type and your condo board’s rules before buying anything. Some buildings restrict exterior venting entirely, in which case a portable AC isn’t an option regardless of which one you pick, and a window unit or in-suite ductless system needs board approval instead.
BTU is measured under old lab conditions with the exhaust hose disconnected, which inflates the number. SACC (Seasonal Adjusted Cooling Capacity) is the DOE-mandated 2017 standard, tested with the hose attached like real use. Always compare SACC, not the BTU headline number, when sizing a room.
Yes. A single-hose unit pulls replacement air from wherever it can find it, including back through gaps around your door, which makes it work harder. A dual-hose unit draws intake air from outside instead, and is measurably more efficient, though it needs a bit more window width to install.
Not well with an off-the-shelf kit. The Dreo AC515S’s 17″-53″ adjustable panel is the narrowest fit we found, but a true fixed or crank window with minimal opening needs a custom-cut insert, not a stock venting kit.
Anywhere from about 42dB to 55dB among the models here, roughly the range between a quiet conversation and a running dishwasher. If noise matters, check the specific decibel rating, not just the brand’s marketing name for a “quiet” mode.
Yes. Some buildings restrict exterior venting through windows entirely. Check before buying, since no portable AC gets around a building rule that prohibits the hose from being visible outside the window.
The most honest BTU-to-SACC ratio of the four, and the quietest
Tight condo window? The Dreo AC515S‘s 17″-53″ kit is the narrowest fit we found.
