Ask a rental counter for an air conditioner and you get a wheeled portable or a spot cooler, not a window box and not an installed system. A one-ton unit is commonly around $350 to $600 a week, it plugs into an ordinary outlet, and it has to duct its heat somewhere outside the room. Fitted air conditioning is a contractor job and a different trade.
What you can actually hire
Rental fleets carry wheeled portables of one to five tons and larger trailer units. Nobody hires window boxes, and nobody hires split systems, because both are fitted rather than dropped off. If you want a bedroom cooled for a fortnight in August, the honest answer is a portable with a window kit and a hose to the outside.
The exhaust duct is not optional
A portable air conditioner pulls heat out of the air and pushes it down a flexible hose. With that hose lying on the floor, the room ends up warmer than when you started. It has to reach a window kit, a door panel or a ceiling void. A run over about 25 feet, or a duct with three bends in it, costs you real cooling capacity.
Minimum hire and the weekly break
Most counters hold a one-day minimum on a small portable and a weekly minimum on anything over three tons. Because a week is usually priced near three days, a hire of four days or more should be booked as a week. Ask what the collection cut-off is, since a unit returned on Monday morning often still bills the weekend.
Power, water and noise
A one-ton portable draws about 12 amps on a normal 115V circuit, which is enough to trip a breaker already carrying a fridge and a microwave. Every unit condenses water into a tank or a pump line that somebody has to manage. And a compressor in the room is loud, which matters more in an office or a bedroom than on a site.
Questions people ask about rent air conditioner
How much does it cost to rent an air conditioner for a week?
A one-ton portable typically runs $350 to $600 for the week, with delivery charged separately if you are not collecting it. Larger units scale roughly with tonnage, and a five-ton machine is several times that figure.
Can I rent an air conditioner for one day?
Usually yes on the small portables, which most counters hire on a one-day minimum. Anything from three tons upward tends to carry a weekly minimum because delivering and collecting it costs the yard more than the day earns.
Is a rented unit strong enough for a whole house?
No. Portables cool one room reasonably and struggle beyond it, because the cold air does not travel and every open doorway is a leak. Whole-house cooling for a broken system is a case for a larger ducted rental unit sited outside.
