Answers: there are many kind . but if you have an oil furnace , the # 1 tip i can contribute you is to change the filter regularly . like every 2 months . also draw from a yearly service done on it . mine usually costs 85 $ canadian , and the technician at that time lets me know how everything is . my furnace is 25 years prehistoric and we have had massively few problems by doing this . hope this helps you .
