The winters here in Arizona are not as intense as they can be elsewhere in the country. However, that does not mean you should not be excited for when the temperatures drop at night. You finally get to turn on that old furnace of yours that has been lying in wait throughout the year.
Have you ever wondered when was the last time you checked in on it? Is it even working properly? Do you know how old it is? You can get so used to the heat that you forget you even have a furnace. You might also not know when it could be time to replace the unit.
