Getting the perfect temperature control going on in your home can be a difficult task all together.
A lot of it has to do with the age and type of central heating and air conditioning system you may have.
If you do not have central heating and cooling, I have to tell you that having some kind of central HVAC unit is the best way to accomplish the perfect temperature control in your home. The best way these days, is with a zoned HVAC unit. Zoned HVAC units create heating and air conditioning zone control in your home to where you can have different temperatures all over the place. Not a lot of people I know have zoned HVAC systems, but the few people I do know with heating and air conditioning zone control have told me nothing but positive things about the way they have the perfect temperatures going throughout where they live. With heating, you may want to run your central heater along with something like a space heater, for instance. That way, you have the space heater to take care of the parts of the room that the HVAC system is not heating properly. With air conditioning, you may want to get a window air conditioning unit in addition to your central air conditioning system to do the same thing. Or, a few other options would be a swamp cooler or even a small ductless mini split air conditioning system. Everything I mentioned is a great way to get a handle on the perfect temperature control in your home!
