What Type of Furnace Is Right for Your Home?
Thinking about upgrading your furnace but not sure where to start? Modern furnaces offer exceptional efficiency and various features designed to keep you comfortable year-round.
The first step in choosing a furnace is choosing the right fuel type.
Natural Gas Furnaces
- Natural gas is the most common fuel type, supplied by your local utility company through an underground gas line
- Cost-effective and stable, with no need to worry about price fluctuations or storage
- Recommended if your home has access to a natural gas line for reliable, efficient comfort during the coldest days
Oil Furnaces
- Popular choice in regions like the Northeast where natural gas lines may not be available
- Oil furnaces last longer than gas furnaces but are less efficient and require a storage tank
- Oil prices fluctuate more than natural gas, making heating costs harder to predict
