"We were on vacation earlier this week when my son-in-law stopped by to check the house. He noticed that the heat was not coming on. Knowing that a cold snap was hitting, I didn't expect to get help quickly. Instead, Cosby had a guy there in 2 hours. He discovered that our geothermal unit was totally out of coolant. He investigated and found a small leak caused by a factory defect. He fixed it and refilled the coolant. He had everything working by the time the below-zero temps arrived. Most of the cost was covered under our maintenance agreement and the factory warranty. Thank you, Cosby! "
