How to lower the cost of running a portable air conditioner
A portable AC sits inside the room and vents hot air through a hose, which makes it convenient but less efficient than a window unit: some of the heat it removes leaks back in, and single-hose models pull warm outside air into the room. A common 10,000–12,000 BTU portable unit draws around 1,000–1,300W. Dual-hose models are more efficient in hot climates.
- Keep the exhaust hose as short and straight as possible, and insulate it if it gets hot.
- Choose a dual-hose model for rooms you cool every day.
- Close blinds on sun-facing windows during the hottest hours.
- Long, hot summers in Texas mean cooling equipment can run most of the day from May through September — try 10–12 hours above to see a peak-month cost.
