There is no right or wrong when it comes to set hot and cold temperatures for your home, however this is a matter of preference, especially when you have an Heating and A/C method to control using a thermostat.
Whether you are using a heat pump, an AC, or an oil furnace, your set temperature is strictly dependent on you.
However, there are some settings that come with the air conditioning unit. These are dependent on the season since appropriate hot and cold temperatures for summer season may not necessarily be perfect in winter, and learning these differences makes it possible for homeowners to enjoy using their units for longer without worrying about any losses from excesses, but note that the style of thermostat may also determine the hot and cold temperatures you set for both seasons. However, it is possible for homeowners to save more than 10 percent on utility bills monthly if they set the thermostat hot and cold temperatures between 7 – 10 degrees Fahrenheit in the summer season and winter season for no less than 8 hours a day! On the other hand, the US energy department recommends a temperature setting of about 78 degrees in summer when at home. Sixty-eight degrees should be set in the Winter when you are home. You can combat the chilliness of the weather by wearing warmer clothes rather than increasing the temperature. However, if you must, then consider increasing the thermostat’s temperature upwards by just a single degree. Setting the temperature control right makes a big difference and can be the only reason you maintain reasonable monthly bills regardless of the season. If unsure of how to go about all this, seek professional assistance from Heating and A/C corporation experts, especially on the choice of temperature controls.
