"If you’re a new customer they will get to you quickly. Not worth it! I had 2 ac/heat units replaced in December 2021. One of them has made noise and the air has an odor. Omar had his tech come out on multiple occasions. Never found anything wrong. Over a year later I reached out to American Standard and they are awesome. I suggest their equipment just not ABC. Omar replaced my system without inspecting the ducts. Even after all my complaints. Finally one of his guys came out and found the damage that was from over 5 years ago. My family has been breathing unhealthy air for a year. Omar has not shown an ounce of care to fix the problem. Which is partially under warranty. I will gladly pay extra to hire a new company to fix the problem. I don’t want to deal with a company I can not trust. I paid over 18,000. I am having to use a space heater in the back of my house to keep it warm. Again I do suggest American Standard. They have been awesome and caring about my situation."
