Why is my AC not keeping up with thermostat?

The AC Needs Maintenance You might be low on refrigerant or have a worn out motor or a dirty evaporator coil. Not all AC problems demonstrate themselves with loud sounds or funny odors coming from your system. Some of them simply reduce the AC’s ability to run, and all you notice is less cool air in the house.

Can a thermostat mess up AC?

Under most circumstances, a bad thermostat will not have any effect whatsoever on the air conditioning system. The AC system is a completely separate entity; the only connection it has to the engine is at the compressor pulley, which derives its power from the crankshaft.

Why does my thermostat not turn on when the air conditioner is on?

If it is not, the thermostat cannot signal the air conditioner to cycle on. Look for and address simple reasons why the thermostat isn’t getting power, such as dead batteries or a tripped breaker or blown fuse in your main electrical service panel.

What should the thermostat be when the AC is running?

However, when homes start to grow hotter than normal while the air conditioning system is running, people often resort to a simple “solution”: they turn down the thermostat further. The recommended temperature setting during the summer is 78°F (this comes from the Department of Energy).

What happens when you turn down the thermostat in Your House?

First, we want to clarify how a thermostat works to show that lowering it isn’t a way to get more cooling. The thermostat doesn’t operate like the throttle in a car. You aren’t pushing down a pedal that makes the air conditioner “ramp up” and produce greater levels of cooling.

Is the thermostat a switch or a switch?

You aren’t pushing down a pedal that makes the air conditioner “ramp up” and produce greater levels of cooling. A thermostat is actually a switch; a switch often connected to complex computer controls, but still a switch that’s “on” or “off.”

What happens when the thermostat is set to cool?

Once it is ready to go, switch it to “on” or “cool.” With it set to the correct temperature, the thermostat will call the AC unit to start cooling your room. Once you’re enjoying the cool air again, it would be awful to have it shut back down again right away.

How do you reset your air conditioner thermostat?

It’s often used as a metaphor, but your thermostat might literally just need you to hit the reset button. If it does, give it a three-second push and release it. Repeat that process and listen for your air conditioning unit to respond with a few beeps.

What should the thermostat be at at night?

In the summer, we set our nighttime thermostat to 67°. In the winter, we push it down even further, to 64°. To some of our friends, who don’t flip on air units until the outside temperature reads 80° or more, we are comical.
