This goes true for any of the states that get cold.
The cold is knocking at our doors so get with it.
If you have a Gas or oil furnace...this IS NOT a DIY job. Call in a professions. It could save your life and the lives of your family.
Those with wood stoves and fire places. That chimney needs to be inspected. Don't wait until the smoke is rolling back into the house. I had my chimney cover come off mine and I got a squirrel in my fireplace. So don't take it for granted that it is ok.
If you have a wood boiler, now is a good time to fire it up at a lower temp and check the gauges and the water pressure before you get up to full temp.
A little bit of checking can save a lot of time, money and lives.
DO IT NOW!!!
Good seasoned wood will also help keep your chimney clean.
