I was impressed with the speed and friendly professional service I received from the phone person and technician. She knew who I was the second called, explained the situation that a tenant of mine had, and 2 minutes after I hung up, I received a call from the technician saying he was there, problem solved with no charge, since unit was still under warranty.
Response from Mason Air Conditioning & Heating:
Your kind words mean a lot to us. Thanks for the positive feedback.
