The Ac cools and heats the house super quick. Very quiet don’t even know it’s on. Hasn’t impacted the electricity bill by much at all. The installation process for the electrician was quick and easy highly recommended by electrician. The look of the unit is quite nice and doesn’t look out of place. This air conditioner unit is outstanding value for money. It works great for cooling and for heating. It works just great in either season. You can here it ramp down after it has reached the desired temperature and therefore save power. It would have to be the quietest one on the market.
