When you have an overly freezing home there is no need to have to turn your heating system up all of the way.
There is something you can use to keep those electric bills down and get your home to decently warm.
Buy a portable section heating system and run it on the very low setting while running your central heating method how you normally would. You won’t have to crank that thermostat anymore! The heating from the portable heating system on the very low setting will make it so that it evens out the offset of the freezing temperatures in your home. Another idea would be to invest in HVAC zone control. But to do something like getting a zoned heating and air conditioner method you better have a ton of money to spend and be well off financially. Because zoned heating and air conditioner units are far from cheap! They are nearly double the price of what a usual HVAC method is. My advice to you is to do what I am saying and get yourself a portable section heating system to help heat your overly freezing home with the uneven temperatures. The reason for overly freezing homes most of the time is because there is something off with the build of the house or the general air flow of the central heating and the air conditioner unit. But a portable section heating system can assist in making it so you can save money and not kill your HVAC systems by turning up the heat all of the way.
