I had a new split unit installed 3 months shy of 2 years ago. Called Action Air yesterday and they sent out Alvin who is probably one of the nicest guys on the planet. He really knows his stuff too. He found the issue within 5 mins of being here, determined it very well was an unfortunate solder joint that was present after the install and had it fixed in probably 15 mins max. I would highly recommend Action Air based off the experience I've had with them over the last couple of years. They back their products and services.
