Now normally, the two rooms downstairs which make up my office have their airconditioners running fairly solidly.. little 1.3kW, fairly quiet unit in the office itself, and a 1.5kW fairly noisy unit in the front room.. They usually run on around a 20% duty cycle in the colder weather..
Walked into the office when i got home from sydney this evening, and it was 16C in the office, and both aircons were off! Had to go hunt out the trusty speedy heater I keep in our camping kit! 🙂
