Dale came through after an installation problem, then a technician problem - Dale showed up and within minutes realized the reason the compressor was not getting power was because the breaker was not operating properly. HE REPLACED the breaker and it worked perfectly. He verified for me that the unit works better with the new compressor saver ( which I was losing faith in). He repaired the rodent screen that Josua tore off when he crawled under the house looking for broken wires. Dale is the best you have ever sent me -please let me keep Dale as my technician.
