To adjust the damper lever, you will need to turn it to the left or right. If you want to close the damper, you will need to turn the damper lever in the opposite direction of the duct. If you want to open the damper, you will need to make sure it is running in line with the flex duct.
Press or slide the "On" setting switch to "AC On" or "Cool." Adjust the slider lever, turn the temperature knob, or press the up and down arrow buttons on the thermostat until the desired temperature is indicated on the display or where the knob/lever point lines up with the printed temperature desired.
According to the Department of Energy1, 78° Fahrenheit is the sweet spot for air conditioners to balance energy savings and comfort when people are at home and need cooling.
"Air-conditioning systems run most efficiently when they're running at full speed," she explains. So while your unit might make more noise initially cooling a space down from 80 to 75 degrees, running all day at a less powerful speed requires more energy overall.
Keeping your fan on AUTO is the most energy-efficient option. The fan only runs when the system is on and not continuously. There is better dehumidification in your home during the summer months. When your fan is set to AUTO, moisture from cold cooling coils can drip and be drained outside.
Your AC will actually run longer overall if it is left on all day instead of being shut off. If you turn it off for part of the day, it runs less and results in more energy savings for you. In almost all cases, it will save you money to shut off your AC while you are away from home.
What Temperature is Too Cold for a House? While everyone has a different tolerance to cold, ideal winter heat settings should generally be at or above 63 °F (17 °C). Excessive cold (anything below 62 °F or 16 °C) in your home can actually raise your blood pressure as your blood “thickens” in the chilly temperatures.
Set your thermostat to 68 degrees Fahrenheit in the winter
According to ENERGY STAR, setting your thermostat to 68 degrees Fahrenheit (20 degrees Celsius) when you're home is the ideal balance of comfort and energy efficiency.
The ideal AC temperature for sleeping is around 65°F (18.3°C). However, this may differ between individuals, who might find their ideal AC temperature lies between 60 and 67°F (15.6 and 19.4°C).
A fan clogged by dirt, a stuck wheel, broken motor, or a loose fan belt are all common problems that reduce the amount of airflow you feel coming from your vents.
This is more of a personal question, as different people feel comfortable at different temperatures. 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.
According to Energy.gov, the better way to save money on heating bills is to set back the temperature of your home at least 8 degrees for 8 hours or longer (while you sleep). In fact, you can save 1% on your heating bill for every degree that you lower the thermostat.
What temperature should I keep my thermostat in winter? When Home: 68-70 degrees Fahrenheit. When Sleeping: 65 degrees Fahrenheit. When You're Away: 65 degrees Fahrenheit.
Cold homes are bad for health. If you're struggling to pay your heating bills and your home is cold and damp, your health may suffer. Problems and diseases linked to the cold range from blood pressure increases and common colds, to heart attacks and pneumonia.
Depending on the season, the ideal house temperature for both comfort and efficiency is between 68 to 78 degrees Fahrenheit. In the summer, the recommended thermostat setting is 78 degrees F. In the winter, 68 degrees is recommended for energy savings.
For winter, the ideal thermostat temperature is 68 degrees Fahrenheit when you're at home. Energy.gov 68 degrees is a good room temperature while you're awake at home, but recommends lowering it while you're asleep or away.
They recommend that when it's 90 degrees outside, you should try setting your air conditioning thermostat at 80 degrees or higher. And when it's 95 to 100 degrees outside (and higher), you should set your thermostat at 85 degrees or higher.
Many a time we think that switching off the Television/AC from remote, or just turning the power button off for an appliance makes sure that it is not consuming any electricity. But the fact is that the appliance continues to consume electricity till the plug point is not switched off.
With a ceiling fan, one can feel about 3 to 4 degree centigrade cooler, therefore if it is used along with an air conditioner, the load on the air conditioner can be reduced by keeping it at a higher temperature. In a moderately hot weather, ceiling fans can even allow you to avoid air conditioner all together.
Using the AC Fan for Better Comfort
While leaving the windows open while the air conditioner runs would be an obvious waste of money, it is OK to open the windows to allow outside air in and run AC fans.
Pros to Keeping Fan Continuously Running:
Less frequent starts and stops of the fan can reduce the stress from startup, and potentially help extend its lifespan. Leaving the fan on 24/7 ensures cleaner air, as the air is pulled through the filtration or UV light system (assuming you have one of these features).
