Poor backup service whilst still under warranty

Capital air is great at selling you a unit but thats where the service stops. I have had nothing but problems with both the units that they have installed at my place. They have had to replace the 18000 unit and it still does not work. The 12000 unit had to be moved eventually after 4 attempts to fix. The after service team are so busy that they just want to palm you off before even hearing what the problem is . The price might be cheap but you are going to get nothing but a hard time if you have a problem with your unit. All of my problems are due to poor installation issues and not the product itself
