My renter called me for the third time in one week to say her air was not working. The previous A/C company that had been there two times that week could not get there till the next day. I made a phone call to ECO-AIR and they were able to fix the problem and have her cooling in less than one hour. From that day on, Eco Air now maintains all my rentals. Quick response and reliable work is important to me, and Eco Air has done that for me.
