Idaho is one of the lucky places that experiences distinct four season weather with fairly temperate days and nights throughout the year. However, average winter temperatures do dip into the 30's and occasionally into the 20's overnight, so it's important to protect your Idaho home from the elements.
Keep your home in tip-top shape throughout the winter by beginning the job in autumn. One of the first things you should do is have your furnace inspected. It's important to ensure that your furnace is operational, energy efficient and of-course, safe. Have a HVAC professional come out and have a look. The repairman will clean the furnace, change the filter, check for leaks and unhealthy gases and ensure everything is operating as it should.
