Efficient air were seamless,excellent from start to finish. I had a split system installed in my lounge.Excellent customer service and tradesman.Tradesman left the place how they found it. Spotless. Another company wanted me to upgrade my power board saying it was full.They offered no other solutions.The tradesman Efficent air sent out for inspection said no problem we can move this here to make room for the split system. Saved me a lot of money.Very happy customer and would highly recommend this company. Look forward to using my unit now which will cut my energy bills down. Thank you.
