The weather in St. Johns, FL stays consistently in the upper 60s throughout the day, so depending on how brave of a soul you are at night it is possible that you have never considered a heating installation from a professional heating company before. However, the arrival of children or just middle-age might have you rethinking your stance on what constitutes turning on the heater, at which point you need to think about heating installation or a new heating replacement if the model at your home has sat dormant for years. While it would be nice to just fire it on and expect it to come to life, the reality might be very different.
