Once you decide on a residential furnace replacement Lannon, you can look forward to selecting a new, high-efficiency model. This is an investment in your family's comfort, your home's efficiency, and long-term savings.

Upgrading to a modern furnace offers significant benefits. Improved energy efficiency means the unit converts more fuel into heat, leading to lower utility bills. You'll also enjoy improved home comfort thanks to technologies like variable-speed blowers that maintain consistent temperatures. Plus, a smaller environmental footprint makes it a responsible choice for the community.
To make a confident choice, it helps to understand furnace types and efficiency ratings.
The key performance metric is the AFUE (Annual Fuel Utilization Efficiency) rating. This percentage tells you how much of your fuel dollar is converted into usable heat. An 80% AFUE furnace wastes 20 cents of every dollar, while a high-efficiency 97% AFUE model wastes only 3 cents. That difference adds up quickly.
| Feature | Standard-Efficiency Furnace | High-Efficiency Furnace |
|---|---|---|
| AFUE Rating | ~80% | 90-97% |
| Energy Savings | Lower | Higher |
| Upfront Investment | Generally lower | Generally higher |
| Operating Cost | Higher | Lower |
| Comfort | Basic | Improved, more consistent |
| Environmental Impact | Higher carbon footprint | Lower carbon footprint |
