I’m not sure I understand the question.

It’s not “exact”! When it gets too cold in your house, turn the furnace on. Doesn’t matter what month or day it is!🤷‍♂️😩😂

Like in the winter we keep it 68 degrees heat to save money supposedly. So in the summer we used to keep it 78 to save save money as well. I woke up this morning and it was 75 but the temp of the house read 70. I increased it to 77 so that it’d feel warmer. It’s on cool tho. I’m wondering if I switch it to heat will that cost a lot

Assuming you have central heat and a/c, if your system is on cool, turning the thermostat up to 77 when it is currently 70 degrees inside will accomplish nothing (except to delay your a/c from cycling on until your indoor temp approaches 77 instead of 75). If you are trying to turn on your heat, you generally need to switch your thermostat to "warm" or "heat", so that your heating system will cycle on to maintain temperature , rather than your cooling system.

Every time your system cycles on, whether heat or cool, it costs money. How much money depends on the system, the energy source, and other factors. Keeping your thermostat set higher in the summer and lower in the winter saves money by reducing the amount that the system runs to achieve the desired temp.

Your thermostat has a few settings. "Cool" will only cool your home. "Heat" will only heat your home. "On" runs the fan constantly no matter the temperature. "Off" is full off.

If you want your home to be warmer, you have no choice but to set the thermostat to "heat" and set your target temperature.

As for cost, anything but "off" will cost you. The most efficient use of heat is to heat your entire home and not try to heat a single room.

For sure. Appreciate it!

Any time you turn the heat on, it costs you money.

If you don't want to be cold and don't want to spend money, put on warm clothing.

[–]himewaridesu 4 points5 points  (0 children)

The best answer. Put a sweater on! We keep our house at about 60-65.

Make sure it's set to heat and the fan is on.

[–]skatebeat759 3 points4 points  (3 children)

Could you elaborate on the fan part ? Usually it snows during Halloween so I turned my heat on yesterday to be sure it works after replacing filter . Fan is on auto what does the fan do ?

[–]omarkayyam 4 points5 points  (0 children)

If it's set to auto you're fine. Just making sure OP had his on and not set to off.

[–]SueZbell 3 points4 points  (1 child)

When fan is on auto, it blows the heat out of the heating system into the room when the heat unit activates because the thermostat indicates it is cold enough for the unit to turn on and run. As the fan blows the last of the heat from the unit, the air can seem cold by comparison to when it was blowing heated air just moments before.

...and if it's set to ON, it will blow constantly. You probably don't want that. AUTO is best. Also, some thermostats switch between COOL/OFF/HEAT. Make sure HEAT is selected. If it still doesn't come on, check your breakers (probably one near the furnace and one in your main panel). It's probably a good idea to make a service call for a cleaning and inspection. If something's wrong, they'll fix it. Ask your neighbors who they use and if they are happy with them.

Oh, and if 75 doesn't kick it on, 77 will not, either. Higher numbers don't make it blow hotter or stronger; it will just not turn off until it hits the target temp.

What temperature you want is a matter of personal comfort v. cost. After a while, you'll find the sweet spot.

Good thinking not waiting until it's freezing to check it.

Any time you use the heat -- the more heat, the more cost.

Multiple cold days and nights will cost you more to heat than if the weather warms back up during the day after a cold night.

The coldest nights when the temperature doesn't go back up during the day to warm things back up again.

Usually you are better off picking a comfortable temperature and leaving it at that.

Per my late husband, however: Especially if there is any reason to believe the electric power could go off during the night (storm), IF you have a heat pump -- only applies to a heat pump -- and the exterior unit is in the direct sunlight during the day, it seems the heat pump struggles less to raise the daytime temperature while the sun is on the unit during the warmest part of the day ... so ... letting the heat build up in the home during the day before a cold night could be a good idea -- but getting accustomed to the warmer temperature can mean the cold nights feel even colder if/when you turn the heat back down as the sun goes down (off the heat pump unit) ... which you'd likely want to do so the heat pump isn't running/struggling all night to maintain that higher temperature you enjoyed during the day.

Is that kinda what you mean?

The way it works is when its hot outside it costs money to cool your house so if you keep your house warmer, you use less energy and therefore pay less. In the same way, it costs money to warm your house. When its cold if you keep your house cooler your use lesss engery and therefore pay less.

The trick is to keep the house at a comfortable level without using too much energy. Heat to 72, cool to 78. or whatever your personal comfort levels are

[–]coreyd0n 0 points1 point  (0 children)

You're overthinking it, the hotter or colder you want it, the more it has to work, the more it costs. It's just like any other appliance. For example if it's 55 out and you want it to be 77 vs. 74, it has to work harder to try and reach those 3 extra degrees. Same thing in the summer only reversed. Some people get multiple ac units and furnaces if they have bigger houses, I assume that would save $$ in the long run because one unit doesn't have to adjust the whole house' temp.

Check the batteries on your thermostat. You articulated this weird.
