Understanding the Efficiency and Size of Your Furnace is Important
A furnace is measured by it's BTU (British Thermal Unit) rating. Which is an indication of the capacity or ability of a furnace system to heat the necessary space. Most furnace manufacturers make several sizes of their models. Common sizes are 40,000-, 50,000-, 60,000-, 80,000-, and 100,000-BTU units.
AFUE refers to how efficiently the unit turns fuel into heat for the home. Modern furnaces have an AFUE rating of 90% and higher, meaning these high-efficiency units are the best at putting your energy dollars to work and can also lower energy bills.
We recommend installing the smallest, most efficient system necessary to adequately heat your home for energy savings and system efficiency.
When you have an oversized furnace installed, it can be a costly mistake. Ideal temperatures will be reached too fast and the unit won't be as effiecent. When a furnace heats your home too quickly it will short-cycle, meaning it will only give off short bursts of heat at a time. The downfall of a furnace that gives short, frequent cycles is that it causes deterioration, temperature fluctations, shortened system life, and higher operation costs.
