Whether you’re looking to upgrade, replace, or install a furnace in your new or existing home, ]choosing the perfect furnace replacement will benefit you for years to come. Before you start searching, make sure you understand the following three factors that determine how appropriate a furnace is for your home.
1. Type of Fuel
The first place to start is by determining what fuel your new furnace will run on. While it is often easiest to use the same fuel that your current or old furnace used, it’s not necessarily the best idea. Consider the availability and cost of different fuels that you have access to and pick the cheapest reliable fuel.
2. Furnace Capacity
The heating capacity or size of your furnace will affect both the performance and efficiency of your HVAC system. A common error is to pick a furnace that is oversized, which will turn on more frequently than you need, warming more than you need and warming unevenly throughout the home.
Before any furnace replacement is chosen, ask your HVAC contractor how he/she will determine the size. Rules of thumb often result in an oversized unit, so the answer you’re looking for is that they are using the Air Conditioning Contractors of America’s Manual J. The procedure in this manual takes into account many factors that affect heat retention and dispersion in your home like insulation, airtightness, layout and size.
3. Level of Efficiency
The efficiency of your replacement will determine if your energy costs rise or fall. A more efficient furnace will waste less fuel, and therefore waste less energy heating your home. Compare the extra cost of a high-efficiency furnace upfront with the energy savings that you will get throughout the first decade of operation. If the savings justify the initial expense, opt for the high-efficiency unit.
