Dennis assisted with fixing my dryer. He was quick to diagnose the problem and was able to replace the motor the following day. It was cheaper to replace the motor than purchasing a new one. Thanks Dennis for making a quick fix and saving me some money!

Global HVAC&Appliance Repair was first to respond to my service request. They came over on same day. Dennis and his associate was on time, quickly identified the roo cause -- a broken compressor and replaced it with a new one. The job was finished swiftly with quality. They also cleaned up the work area before they left. The overall repair experience was very satisfactory. I will call them again for furture repair needs.

Dennis called me right away when I requested help with fixing our ice maker. He came out, diagnosed the problem and said we needed a replacement. He ordered it and returned the next day to install the new ice maker. I was very pleased with his work and would use him again for any appliance repairs.
