The answer to 'should I get furnace or' is that the choice between a furnace or another heating system depends on your specific home and heating needs. Furnaces are a common and reliable choice for whole-home heating, providing warm air that is distributed through ductwork. They are generally more cost-effective to operate than other options like boilers or electric heating. However, the upfront cost of installing a furnace can be higher than some alternatives.
When deciding between a furnace or another system, consider factors like the size and layout of your home, your climate, energy efficiency needs, and your budget. A professional HVAC technician can evaluate your home and recommend the best heating solution. They can also provide guidance on features to look for, such as high-efficiency models, smart controls, and safety features.
