Temperatures finally seem to be on a cooling trend, signaling winter isn’t too far away now. We’re assuming that since you’ve found this blog post, you either do not have a whole-house heating system in your home, or yours is at the point that no amount of repair is going to bring it back to life.
We will also assume that you don’t want to just rush out and buy the first heater you can find. This typically ends up being a mistake, since you need that heater to be properly sized and matched to your specific home and needs.
