My remote control for my very old (discontinued) air conditioning unit was not working and I rang Airmate 92761435 to see if they could help. I can't remember the last time someone went out of their way to be so helpful. Kelly took my information,rang a technician, got the relevant information and relayed it back to me within 30 mins. What I thought was going to be an expensive exercise to set right was rectified over the phone with detailed information on how to reset the handpiece. This information is not contained in the manual
