North america is so large that those residing in the northern most states experience a significant amount of cold weather and the ones lucky enough to live down in the southern states enjoy sunshine and summer for the larger part of the year. However no matter where you reside you either have to heat or cool your property to a comfortable temperature. Being in the north means during the winter months you’re positive to have a good heating system in addition to warm blankets. You have to keep the house at around seventy degrees Fahrenheit to remain comfortable, which is no modest task. If you are fortunate enough the house will also have heated floors to warm up those cold feet. Down south instead of focusing so much on heating an air conditioning system is imperative. Your house down there has to keep stifling heat from taking over your living space. It also should be kept cool enough to refresh someone coming in from the hot sunshine outside. Small window unit air conditioners won’t complete the task in this case; often whole home HVAC units are essential. And the thing is, even down south a heating system remains required. Although they have heat almost all of the year it can still start to get cold enough to require some extra warmth in your home. Few places in the U. S. are warm enough year round to avoid needing some kind of heating unit. The areas in between these two extreme climates in America have cold winters and warm summers. These regions especially need the heating and cooling capabilities of an HVAC system to keep the living area at a comfortable temperature. The temperature is a hard thing to control throughout every season and can also be incredibly unpredictable. Regardless of where you live, some sort of heating or cooling system will be needed to create an inhabitable home.
