How much does a new furnace cost for a 2000 square-foot house?

A new furnace for a 2,000 sq ft home doesn’t have a single set price; Sierra Air Conditioning & Plumbing offers heating system installs for as low as $199 per month with a free estimate. The final cost is set after an in‑home assessment to match the correct furnace size and efficiency to your house. Our team regularly sizes and installs systems in Enterprise and the greater Las Vegas area, and a proper load calculation prevents short cycling and uneven rooms.

Key factors that change the price:

• Furnace capacity (right BTU size for your home)
• Efficiency rating (AFUE) and fuel/venting needs
• Ductwork changes or sealing
• Thermostat and indoor air quality options
• Installation complexity and accessibility

If your current unit is aging and needs frequent fixes, replacement often beats repeated repairs over time. Book a free in‑home estimate to get an exact price. <br/> Updated: 2026-04-02 <br/> Need help in Enterprise, NV? Call (702) 710-9106 or book online.
