Thermostats
Thermostats, after the system is actually working
A thermostat is the control, not the air conditioner. In Jupiter it gets blamed for humidity, hot rooms, and short cycling that start in the equipment or the ducts.
What we’d tell you first
Plain notes, the way a tech would say them on the phone. Then call or book if you want someone at the house.

A new thermostat doesn’t clean a coil
If the house won’t cool, the control is the last thing we blame. Airflow, the drain, and the outdoor unit come first.

Match the system you have
A heat pump needs a thermostat that knows the difference between the compressor and the heat strips. The wrong one runs expensive heat.

Batteries and schedules
A blank screen is often batteries. A schedule that sets the house to 78 while you’re home is not a failed system.
What we check before we sell one
Setpoint, batteries, and whether the thermostat is even calling. Then airflow, the drain, and the outdoor unit. If the house is cold and clammy, a touchscreen will not wring the air out.
Replacement makes sense when the control has failed, the wiring is wrong for a new heat pump, or a renovation needs a thermostat that can run the system you have — including a mini-split or a zoned house.
Scheduling around real life
Away settings help a seasonal house, and they can also let humidity climb if the system never runs long enough. We set that up after the equipment can actually dehumidify.
Questions we’d answer on the phone
The short version before anyone is standing in the yard.
Will a smart thermostat lower my electric bill?
Only if the system and the ducts are already doing their job. A thermostat cannot fix a filmed coil, a choked filter, or ducts that leak into a hot attic.
