Some people do not realize that no matter how advanced heating and cooling technology is, there is always going to be something that is not perfect about a heating and air conditioning system.
Even the most brand new and up to date central heating and air conditioning system will not be perfect. Especially if you live in an area that has either super hot or super cold times of the year. During those times of the year you will find that most central heating and air conditioning system units do not perform to their fullest. This is because they can not handle the extreme heat or the extreme cold they are up against trying to fight off. Like I mentioned, even the most brand new, up to date, very expensive, and all so extremely powerful central heating and air conditioning systems can not combat super extreme cold or super extreme heat. This is where in order to have indoor comfort during these times you may consider getting a portable space heater for the winter and then getting a portable air conditioning system for the summer. Because if you run the portable space heater or the portable air conditioning system at the much needed times along with your central heating and air conditioning system you will find that it will even out the uneven and odd temperatures in your home and make the indoor comfort that you wish to have. This is what I do. And it all brings it back to the main point of saying, that no central heating and air conditioning system is perfect!
