Called Poston for heat pump concern and they were out the next day. Dave gave me a full description of the work he was going to do and was very respectful. He confirmed there was no issues and believed that ICE may have been the issue. He allowed me to witness his observations which helped me understand further. He complemented the condition of the furnace while completing a winter maintenance and then discussed the new service plan Poston is offering. I was sold immediately and look forward to using Poston going forward! Well done all around.
