About two years ago, I realized our oil furnace needed to be upgraded. It was no longer capable of handling the serious Wintertime weather in our area. I observed much longer run times in addition to much higher daily energy bills. The beach house often felt cold, no matter how high I set the temperature control. The oil furnace had also begun making some odd sounds, spread quite a bit of dust from the vents, in addition to smelled rather musty whenever it operated. My family often complained of headaches while I was in the Wintertime, in addition to I blamed the oil furnace. Rather than wait for the oil furnace to fail while I was in the middle of the Wintertime, I decided to take proactive measures. I started researching what to look for in a new oil furnace, with the plan to handle the upgrade process over the Summer. I discovered that the bizarre manufacturers in addition to models offer basically the same features. The AFUE ratings vary, along with price, in addition to most top-of-the-line oil furnaces are equipped with variable-speed operation, stainless steel heat exchangers in addition to zone control capability. The Energy Star rated oil furnaces tend to be more expensive however save money on heating bills every week. From what I read, the model of oil furnace is not as important as official sizing in addition to upgrade. Some Heating in addition to A/C companies tend to oversize the oil furnace because it’s easier than making accurate heating load calculations. Unfortunately, greater oil furnaces cost more to purchase in addition to won’t supply superior comfort. The system will heat up the area too quickly in addition to never achieve maximum efficiency levels. A oil furnace that is too small will run continuously in addition to never manage to sustain perfect comfort on super frigid days. Whether the oil furnace is over- or undersized, it will experience excessive wear in addition to tear in addition to not last as long.
