Getting a new furnace and AC at the same time boosts energy efficiency, comfort, and air quality. It also brings big savings over time. Unlike DIY, professional HVAC installation often comes with warranties for extra peace of mind.
Factors Influencing the Cost of New Furnace and AC Units
When you install a new furnace and AC, many factors affect the cost. Knowing these can help you budget and make choices.
The size of the unit is key to determining the cost. A new AC and furnace for a 2,000-square-foot home with a 3-ton air conditioner averages $5,750. Prices range from $3,300 to $7,800, based on your specific needs and extra features.

Energy efficiency plays a big role too. Units with higher SEER (Seasonal Energy Efficiency Ratio) ratings cost more upfront. The U.S. requires a minimum SEER rating of 14 or 15. But, models ranging from 14 to 22 SEER vary in efficiency and price. Generally, more efficient AC units can be 10% to 50% pricier than basic ones, but they save money on electricity in the long run.
Extra costs can come from needing new ductwork, adding $1,000 to $5,000 to your bill. Installing zoning systems ups the cost by 20% to 30%, and building permits add 5% to 15%. UV air purifiers increase costs by $300 to $1,000.
The details of your house and its current setup also change the cost. Replacing systems is often 10% to 30% cheaper than completely new ones thanks to existing ductwork. The number and complexity of vents can also affect the price, with each additional vent costing $300 to $500.
Finally, it’s smart to think about how long these systems last and their long-term value. Central AC units last 15-20 years. Frequent repairs or higher energy bills might mean it’s time for a new, more efficient model.
