They came and replaced out air conditioner/heater with a new one. They said there was a one year warranty on their work. But when there were problems I would call and call and get no response. When I finally got ahold of someone, they told me the warranty was only for 30 days. I explained that they said it was for a year, and they transferred me to someone's voicemail who never called me back. I never got a response from them on the repair issues and had to hire someone else to come fix their mistakes. Now our unit is having problems again. All of which are traced back to the installation of the unit by Kleenair.
