My current oil furnace is well over twenty years old. It was already installed when my wife and I bought the house, and it wasn’t current at the time, then over the years, I’ve been diligent about replacing air filters and scheduling professional repair in the fall; There have been few repairs, but I’ve made sure to handle them very rapidly. The oil furnace has been well taken care of and provided reliable heating. The Wintertide weather in our local area creates a important workload. It’s usually necessary to run the oil furnace from early September until mid March. The heating plan combats outdoor hot and cold temperatures down to twenty-more than four below zero and often operates at maximum capacity. I would not want to be faced with a oil furnace malfunction and left without heat during a blizzard. I’d hate to be forced to install a current oil furnace in a hurry because of sub zero hot and cold temperatures, however although our oil furnace is still operational, it’s showing signs of wearing out. I’ve noticed that it runs more often and longer, during the most drastic weather, the oil furnace now struggles to maintain a comfortable indoor environment. It makes a bit more noise, costs more to run and there’s a higher concentration of dust floating around. I suppose it would be wise to be proactive and schedule upgradement for the heating plan before the start of the winter. A current heating plan would offer superior efficiency levels, comfort, safety features and air quality. I could have confidence in its ability to make it through the Wintertide without a problem. The lower weekly energy bills would help to reuse the cost.
