Furnace Replacement FAQ
How do I choose the right furnace?
When shopping for a new furnace, there are many factors to consider. The most important is the efficiency of the new furnace you are purchasing by looking for its Annual Fuel Utilization Efficiency (AFUE) rating. High efficiency furnaces will account for greater savings on heating costs than less efficient models in the long run, though they may come with a greater initial cost upfront. Additionally, it is important to make sure your new furnace has adequate output to heat the size of your home. Finally, consider the cost of furnace installation, as this can be a major factor when budgeting for a new furnace. With careful consideration and research of your new furnace options, you can purchase one that meets all your needs while avoiding unwanted costs and complications due to improper sizing or installation issues.
How long do furnaces typically last?
Typically, a gas furnace lasts around 15 to 20 years if properly maintained and serviced. However, an old furnace may require more frequent service and may start to degrade in performance. Sometimes, old furnaces can cost you a lot in terms of repairs, so it can be beneficial to replace your existing furnace unit ith a new one that is more energy efficient. If your existing furnace is showing signs of age, speak with us about new furnace installation!
Which types of furnaces are the most energy efficient?
The most energy efficient furnace on the market is a 98% modulating variable speed furnace; however, this is one of the most expensive furnaces due to it being so energy efficient. When looking into high efficiency furnaces, you probably see percentages mentioned. These percentages represent the Annual Fuel Utilization Efficiency (AFUE) rating. A higher AFUE makes for a more efficient furnace and lower heating costs. If you’re considering replacing your old furnace, it is definitely worth considering a high efficiency gas furnace despite the greater upfront furnace cost.
