I returned home to AZ to discover the central air wasn’t working. Almost 90 in the House. I call Alaskan Air Conditioning and they had someone out early the next day. Kevin Norton was terrific. He quickly diagnosed the problem—a “grounded” compressor. The a/c should be fixed when the parts arrive next week. Fortunately, I’ll be in NY until the a/c is scheduled to be fixed. While the repair will be expensive, I’m confident it will be done right. Thank you Kevin.
