Winterizing your home is one of the best ways to get comfortable and save energy costs. It’s not too late to get a few projects done before the holidays, so here’s a short weekend list of to-dos to help you.

Check the furnace. Typically, a heating system has a heat/cooling source, distribution system, and thermostat, so there is plenty of room for error. Make sure that your system is properly inspected and cleaned and has fresh filters according to maintenance directions. Call a master certified plumber to look for potential dangers such as carbon monoxide leaks.

Check detectors. Since you’ll be indoors more, it makes sense to also check smoke and carbon monoxide detectors. Smoke detectors with a UL rating have a useful life of 10 years so don’t just push the button to see if it’s working.  Stick a real flame source, such as a candle or a match, to see if the detector can actually pick up on the smoke being emitted.

Check insulation. Energy leaks put a hole in your wallet, so do your best to identify and seal all leaks in your ceiling/attic and cracks in or around your windows and doors. A quick way to check if you have enough insulation is to go into your attic and look at your rafters-if you can see ceiling joists you can add some more insulation. Though this will be an expensive process, your heating costs will drop right away.
