We just had an a/c unit replaced at home and the old unit was a Frigidaire unit with a White Rodgers thermostat. 1999 model
The new unit is a Lennox with a Honeywell Thermostat.
The new unit thermostat clicks twice when the unit comes on and goes off.
The HVAC installer told me that they all do that now because of the relay located in the t-stat.
They say it’s more reliable.
Does anyone know if they all click these days? Is there a quieter one available?:shock:
