Short answer
We serve Mandeville, ZIPs 70448 and 70471, at the north end of the Causeway. Homes here range from older houses near the lakefront to newer subdivisions inland, and common calls are AC repairs, heat pump installs, upstairs rooms that never cool and houses that feel damp in mild weather. The line is answered 24/7.
Two-story homes and muggy shoulder seasons
Many Mandeville homes have a second floor or a bonus room over the garage, and a single thermostat downstairs rarely keeps both levels comfortable. The upstairs sits under a hot roof and gains heat from the floor below. Balancing the dampers toward the upstairs, adding a return or splitting the system into zones with their own thermostats usually fixes it without a second system.
The north shore's spring and fall bring warm, damp days when the air is muggy but not hot enough to keep the AC running. That is when closets smell musty and windows fog. A correctly sized system with the fan on auto helps, and where the house still runs damp, a ducted whole-house dehumidifier holds humidity steady whatever the temperature.
