A five ton portable air conditioner moves roughly 60,000 BTU an hour, which is the size hired when a single small spot cooler stops holding a space: a server room, a tented work area, a kitchen with the fixed system down. It will not run on a wall socket. Almost every unit this size is 208 to 230 volt, and that supply has to exist before the machine arrives.
What five tons will actually hold
Tonnage answers a heat load, not a floor area. In a plain office five tons might cover fifteen hundred square feet; in a room full of servers or under a tent in July it may hold a fraction of that, because the equipment and the sun are adding heat all day. Count the kilowatts of gear in the room before you count the square feet.
The power supply decides everything
Five ton portables are typically wired for 208 to 230 volt single phase and draw enough current to need their own circuit and a specific plug. Confirm the voltage, the amperage and the connector with the yard, and have an electrician confirm the panel can carry it. A machine that arrives with the wrong tail sits on the dock earning nothing.
Where the hot air and the water go
A portable unit does not destroy heat, it relocates it, so the condenser air has to leave through a duct into a ceiling void, a window kit or an adjacent space. Point it into the same room and you will end up warmer than you started. Condensate also has to drain or be pumped, and a five ton unit makes a lot of it in humid weather.
What a day, a week and a month cost
Day rates commonly run $150 to $350 for a five ton machine, and because most hires of this size are emergencies covering weeks, the weekly and monthly rates matter more. A week is usually about three days and a month about three weeks. Ducting, plugs and transformers are separate lines, so ask for the whole package priced.
Questions people ask about 5 ton portable ac unit rental
Can a 5 ton portable AC run on a normal outlet?
No. A standard 115 volt outlet tops out around one ton of cooling. Five ton units are 208 to 230 volt on a dedicated circuit, so the supply is the first thing to check and the most common reason a delivery fails on arrival.
How many square feet will a 5 ton unit cool?
In an ordinary conditioned space, roughly twelve to eighteen hundred square feet. In a data room, kitchen or tent it can be far less, because the load is coming from equipment and sunlight rather than from the walls. Size against the heat load, not the floor plan.
Can I run one from a generator?
Yes, if the generator has headroom for the compressor starting current, which is several times the running load. Yards will normally spec the generator to go with the unit; a set sized to the running amps alone will trip every time the compressor kicks in.
How long can I keep the unit?
As long as you need, and the rate per day falls sharply past a week. Long hires are common while a fixed system is repaired or replaced, and most counters will convert a rolling daily hire onto a monthly rate if you tell them the likely duration up front.
