We are convalescing at the lake today... so all is well. Luckily it was an easy fix... we'd had our son schedule some preventive maintenance work on the units while we were gone. They did it the day before we came home. Apparently loosened some wire which caused it to "reverse".... an easy fix thankfully!! It feels cool here compared to St. Maarten, though the high temperature is close to 90! Enjoying the reports of those lucky enough to still be on island!
