I live in the northeastern part of the country, and our priority is entirely the cold weather. I run my oil furnace for the majority of the year. By mid November, it is necessary to shut the windows, tighten up the house, and prepare for winter. Because of the drastic cold, tremendous amount of snow and bitter windchill, it is important to prevent energy waste. Although my gas oil furnace is fairly energy efficient, it still costs a small fortune to run it for 9 weeks of the year. And with outside temperatures dropping down to twenty below zero, the oil furnace is operating just about non stop. I do everything possible to cut down on the workload of the oil furnace and improve the comfort of my home. Since my lake up-to-date home is severely old, quite large, and features a lot of windows, it is a challenge to heat. There always seems to be drafts and cold spots. I have spent a great deal of time and effort to eliminate the leaks. Over the years, I’ve torn down every single plaster wall and ceiling, added insulation and put up brand up-to-date wallboard. I’ve substituted all of the seasoned windows with thermal pane windows and carefully caulked around them. I’ve installed ceiling fans to combat the heat that tends to rise up and get trapped at the ceiling. I also take legitimately nice care of my oil furnace and am enrolled in an Heating and A/C maintenance plan. Every fall, a licensed Heating and A/C professional thoroughly inspects, cleans and tunes the components of my oil furnace. She makes sure that there is no debris accumulated in the duct system or inner workings which might block airflow. Any worn or broken parts are substituted, wires evaluated and moving parts lubricated. Because of this, the oil furnace works at peak efficiency, costs less to operate and resists malfunctions.
