Just before our vaction we noticed that the AC was not working as effectively as it had been since its installation by Frymire, 11 years ago. We arranged for a service call and the service technician turned up early in the mornng of our first day home. After a thorough inspection of the system he discovered the problem and quickly rectified it. The unit is back working reliably and effectively. The efficiency and accuracy of the service technician was very much appreciated.
