A heat source will trick your thermostat's temperature reader into thinking the entire room is warmer than it is, resulting in uncomfortable temperatures and wasted energy. These items include stereos, speakers, televisions, lamps, and personal heaters.
That usually means that the thermostat sensor is faulty. You have two options. Change the thermostat, or simply ask for a higher temperature. So press the up arrow a few times to change the 74 to 78 and you should feel warmer.
The calibration screw is typically located in a curved piece of metal. First, remove the control unit from the wall mounting and then locate the screw in the back. Turning it back and forth opens the contacts. Once you feel the setting is correct, turn the calibration screw again to close the contacts.
Since 72 degrees is generally agreed upon to be an ideal indoor temperature, most people would probably still feel comfortable setting their AC units slightly higher than this, perhaps at around 75.
The internal parts of the thermostat can't properly read the temperature of your home if it is not level. To fix this issue, remove the faceplate of the thermostat and loosen the backplate from the wall until you can move it enough to square the backplate.
In general, 80 degrees is too hot for a house if people are inside. However, if people aren't home during the day or for vacation during the summer, an indoor temperature of 80 degrees can save energy until you return and lower the temperature.
For many of us, 70 degrees is the ideal indoor temperature, but when it is close to 100 degrees outside, your AC unit will be working quite hard to meet these expectations. Consider setting your thermostat at 75 degrees to 80 degrees in your home if the outside temperature is approaching triple digits.
While ENERGY STAR suggests 82 degrees, that may be too uncomfortable for most families. Most people sleep better when their sleeping area is chilly, so that's why the National Sleep Foundation advises 60–67 degrees.
There are benefits to having your air conditioner set to “auto” and “on.” The benefits of the “auto” setting include higher efficiency, lower energy bills, better humidity control, less wear and tear on some components, and quieter running.
Use the up and down arrows on your thermostat to set the temperature you want your home to reach. You should see a different display number related to the selected temperature. Top Tips: You may hear the system click as it engages and turns on the air conditioning to lower the temperature in your home.
To reset mechanical thermostats, simply turn off the thermostat and flip the circuit breaker. This can be done by going to the breaker panel and turning off the appropriate breaker switch for 30 seconds. After turning the breaker back on, turn the thermostat back on and the thermostat should be reset.
To reset a non-programmable digital thermostat, you'll need to take the face-off and hold the reset button for five seconds. You can also try removing the batteries for five seconds. Both of these methods should result in a reset thermostat.
Your AC might not cool properly due to thermostat issues, an undersized unit, or extremely high outdoor temps—so check those first. Keep an eye on airflow—replace clogged filters every 3 months, and make sure vents and ducts aren't blocked for efficient cooling.
Cooling a house from 80 to 72 degrees is a common goal for many, especially during the peak of summer. On average, this process takes roughly two and a half to three and a half hours.
During a heatwave, we recommend that you don't lower the AC's setting below 68°F. This is already quite chilly for most people, and many would consider it too cold. An air conditioner set this low risk of its coil freezing—and that's bad news because it indicates that the air conditioner is overworked.
In the summer, experts say the thermostat for your air conditioner should be set to at least 78°F during the day when people are at home. That setting is designed to help people avoid high energy bills in the summer. The lower your thermostat setting, the higher your bill.
WHAT SHOULD I SET MY AC TO AT NIGHT? According to the Cleveland Clinic, the recommended thermostat setting for nighttime is between 60°F and 67°F. 3 Setting your AC within this range can help maintain a comfortable sleeping environment.
One possible reason your AC is not reaching the set temperature is that the thermostat could be dirty. If dirt, dust, or other debris has accumulated within the thermostat box, it can cause the wires to heat up or other issues. Thermostats are cleaned during routine HVAC maintenance to help prevent this from happening.
The California Energy Commission recommends that homeowners set their thermostat to 78 degrees when they're home and 85 degrees when they're away from home during the summer.
On average, an air conditioner running in good condition should take about 15-20 minutes to drop the temperature by 1 degree in a standard-sized room. However, factors like outside temperature, unit size, and insulation quality can affect this timing.
The average summer temperature is around 71°F. In winter, this falls just a touch to 70°F. Here's a winter breakdown for thermostat settings across the U.S., according to the survey participants: 47% set it between 68°F and 71°F.
The recommended bedroom temperature range for sleep is typically between 60 and 72 degrees Fahrenheit, with 65 degrees considered the sweet spot for most people, according to Raymann.

Incorrect placement of the thermostat can result in inaccurate temperature readings and, as a result, make the HVAC system run either too long or not enough. This can lead to increased wear and tear and uneven heating and cooling as well as waste energy which leads to high air-conditioning bills.
81°-85°F: Dangerous heat for all dogs - use extreme caution or avoid walking outside.
