Furnace Installation
Warm, Efficient, and Built to Last
A new furnace is a major investment in comfort, safety, and efficiency. Whether you're replacing an aging unit or upgrading to a high-efficiency model, the right furnace, properly sized and installed, keeps your home warm and your energy bills manageable for years.
Sizing and fuel type drive the decision. A good HVAC pro calculates the right capacity and helps you weigh gas versus electric and standard versus high-efficiency, so you're matching the system to your home and climate rather than overspending.

- Homeowners better served by a heat pump
What to Watch Out For
A new furnace is a major purchase
High-AFUE units pay back over time, not immediately
Alternatives to Consider
| Alternative | Better When | Worse When |
|---|---|---|
| Repairing the existing unit | Cheaper short-term | Not worth it on an old or unsafe furnace |
| Heat pump | Handles heating and cooling | Higher upfront cost but may consolidate systems |
Is It Worth It?
For an aging or unsafe furnace, replacement is worth it, delivering reliable, efficient heat and peace of mind that offset the upfront cost.
Questions to Ask Your Pro
- What size and efficiency furnace fits my home and climate?
- Would replacing the AC at the same time save money?
- Are there rebates or tax credits for a high-efficiency unit?
Frequently Asked Questions
A new furnace installed typically costs $3,500 to $12,000 depending on size, efficiency, and fuel type.
Sizing depends on your home's square footage, insulation, and climate, and a pro calculates the right capacity for efficient, even heating.
High-AFUE furnaces cost more upfront but lower your heating bills over the unit's life, which can offset the difference in colder climates.
Often yes. Combined replacement lowers labor costs by $1,000 to $2,000 and ensures a matched, efficient system.
The main drivers are the furnace size and fuel type, its efficiency rating, and installation complexity like ductwork and venting.
