Had a complete AC installed - and not a low end unit. They installed it incorrectly. They hooked up a supply line to what was supposed to be a return line. The error has damaged my home! A month later I am still trying to get the unit installed correctly and the damage to my home fixed. The 100% satisfaction guarantee and no hassle guarantee are just words they use. The customer service has been awful. You would think someone could step up and own this mistake that has damaged my home and try to make it right. No. I'm having to constantly call and demand my home be put back to the condition it was before they stepped foot in it.
