My HVAC professional says not to set below 70 degrees because of possible problems and damage to unit
can a faluty thermostat affect your central ac working?
A central air conditioning unit will commonly turn on and off intermittently. To stop this, adjust the temperature on the thermostat or switch the unit either on or off rather than the automatic setting on the thermostat.
short in the wiring
Turning the thermostat to a higher temperature does not make the air coming out of the vents hotter on a central AC with a heat coil. The temperature setting on the thermostat simply tells the system when to stop cooling or heating, but it doesn't affect the actual temperature of the air being produced. The heat coil or furnace is responsible for heating the air, not the thermostat setting.
An AC digital thermostat in a home or office setting offers benefits such as precise temperature control, energy efficiency, programmable settings for convenience, and potential cost savings on utility bills.
Yes your compressor comes when you set your thermostat to "Fan" setting and you have it on cool setting.
check you thermostat for the temp setting
Yes it needs to be on,and set for the lowest temp,and highest fan setting.
The lowest temperature setting on most air conditioners is typically around 60-65°F (15-18°C). However, the exact lowest temperature setting can vary depending on the specific model and brand of the air conditioner.
The purpose of the thermostat wires outside the AC unit is to connect the thermostat inside the building to the AC unit outside, allowing the thermostat to communicate with the AC unit and control its operation based on the desired temperature settings.
Generally the thermostat setting is too low with the fan speed set at minimum or low, this results in the ac unit operating continuously and not cycling . The room ac unit may be undersized resulting in the ac cooling mode operating continuously so that the compressor does not cycle. Another reason could be that the refrigerant charge is insufficient. Finally, as the ac is visual, therefore icing up will be noticed. A central ac unit is usually out of sight externally to the dwelling or mounted on the roof.
The steps involved in an AC thermostat replacement are: turning off the power to the AC unit, removing the old thermostat cover, disconnecting the wires from the old thermostat, removing the old thermostat from the wall, installing the new thermostat, connecting the wires to the new thermostat, attaching the new thermostat to the wall, and finally turning the power back on to test the new thermostat.
