Two Ways To Help Your Furnace Keep Your Home Warm
Your furnace cannot keep your home warm all on its own. If you have ever sat around a fire on a cold winter night, then you can understand the problem a furnace faces. With nothing to contain the heat, it just dissipates into the night. On the other hand, if you can contain the heat, your fire will keep you much warmer. Similarly, if your home doesn't adequately retain heat, then your furnace has to work harder than it should.
