If you’re renovating a house or having a new home constructed, you want to have a high-efficiency heating and cooling system installed by contractors. On an annual basis, high-efficiency heating systems alone have a fuel utilization efficiency of 90%-to-98.5%.
Were you aware that efficiency levels for new gas furnaces are regulated by law? The lowest efficiency that is allowed is 78%. However, newer gas furnace models are able to achieve roughly 97% efficiency.
When you’ve recently moved into or live in an older home, it may be time to replace your furnace or boiler. On average, furnaces will last 15-to-18 years and boilers from 15-to-30 years. If your furnace or boiler isn’t providing sufficient heat, or if repairs are needed too often, these are potential signs that you need a new unit.
