Office please schedule comfort advisor quote for next week. Monday booked at 11am. Jeanlarroux2@gmail.com Upon arrival I found the thermostat to have failed. This was probably caused by the hurricanes/power surge. The home sits on the water and flooded from the storm. I replaced the thermostat and system is now cooling. The outdoor unit most likely has salt water on the outdoor coil. This can speed up the process of corrosion. While it’s working now I can’t say how long it will continue to cool. The best option in my opinion is to invest towards a new AC System. Unable to examine indoor unit do to flooding and clearing the house out.
