Summer is here, the air is warm, and when you come home from a hot day, you want to feel the refreshing air from your air conditioner.
Unfortunately, that moment of relief can quickly turn to panic when you realize your HVAC system is broken and may need to be completely replaced.
In addition to the obvious question, “How quickly can I get back up and running?”, you’ll also want to know how much it will cost to replace it.
“There are so many variables,” says Josh Conder, division operations manager for ARS Central Division. “You can go from an 80% furnace at the basic end to a 96% efficient multi-stage communication system at the high end, which means the price range can range from $8,000 to $35,000.”
The cost of a new HVAC system is often high, so USA TODAY asked the professional HVAC installers at ARS, a national HVAC repair and replacement company, to explain exactly what homeowners can expect to pay.
What Affects HVAC Costs?
There are so many factors that affect the cost of a new HVAC system. In fact, there are so many that it’s hard to get an idea of the average cost range. “I know it’s good to have a solid answer, but there are so many variables and factors involved, including the size of your ducts and the current condition of your home,” Conder says.
- brand: Some brands like Lennox and Trane tend to be more expensive than brands like Goodman and Amana.
- HVAC system type: Heat pumps are more expensive than central air conditioners because of the way they are manufactured.
- Energy efficiency: The higher the energy efficiency rating (SEER, EER, or AFUE), the higher the cost of the system. The minimum (and cheapest) SEER rating is 14 for northern states and 15 for southern states. You will pay much more for the most efficient HVAC systems with a rating of 20 or higher.
- System capacity: The larger your home, the more tons/BTU you will need. Larger HVAC systems cost more to replace.
- Installation complexity: HVAC replacement often involves more than just the unit itself. If you have an older unit and infrastructure, you may need to update your ductwork, thermostat, and electrical equipment before you can put your new system up and running.
Average HVAC costs by home size
The average cost to replace an HVAC unit is approximately $12,000, but depending on the replacement source, the average cost can range from $7,500 to $14,500. Larger homes require larger HVAC units, so expect your total cost to increase with square footage.
“Replacing a complete system can cost as little as about $12,000 and as much as $25,000, but can be much more depending on the job,” said Joey Dooley, general manager of ARS of Texas. “Once you start getting bigger jobs or additional jobs, you can move up from there.”
| home size | HVAC replacement cost range |
|---|---|
| 1,500 square feet | $6,000 to $10,000 |
| 2,000 square feet | $7,000 – $12,000 |
| 2,500 square feet | $8,000 – $14,000 |
| 3,000 square feet | $9,000 – $16,000 |
HVAC cost for 1,500 square feet
On the low end, a new HVAC unit for a 1,500 square foot home can cost less than $5,000, while more efficient units or multi-unit systems can cost closer to $10,000. If you replace both your furnace and central air conditioner, you can expect to pay between $7,500 and $15,000.
| Types of HVAC units | Average cost per unit |
|---|---|
| central air conditioner | $4,500 – $7,500 |
| furnace | $3,000-$7,000 |
| ductless mini split | $4,000-$9,500 |
| heat pump | $3,700 – $8,700 |
HVAC cost for 2,000 square feet
Heat pumps and ductless mini-split systems start to get expensive as the area gets larger. As your home grows, you’ll have more rooms to heat and cool, so you’ll need a system that’s large enough to handle it. An inexpensive HVAC unit costs around $5,000, but when you add in labor costs, it can easily exceed $10,000.
| Types of HVAC units | Average cost per unit |
|---|---|
| central air conditioner | $5,500 – $9,000 |
| furnace | $3,500 – $8,000 |
| ductless mini split | $5,000-$11,000 |
| heat pump | $5,000-$10,000 |
HVAC costs for 2,500 square feet
If your home is 2,500 square feet, it’s not unheard of to spend $20,000 on a new HVAC system. This is especially true if you own an older home that requires modern ductwork and electrical installation to support modern systems.
| Types of HVAC units | Average cost per unit |
|---|---|
| central air conditioner | $6,000 – $10,500 |
| furnace | $4,000-$9,000 |
| ductless mini split | $6,000 to $13,000 |
| heat pump | $6,000 to $12,000 |
HVAC cost for 3,000 square feet
For homes over 3,000 square feet, HVAC costs are nearly double the cost of a smaller system. Even a single furnace or AC unit can cost more than $10,000, and that’s before labor, ductwork upgrades, and electrical upgrades are taken into account.
| Types of HVAC units | Average cost per unit |
|---|---|
| central air conditioner | $7,000 – $12,000 |
| furnace | $4,500 – $10,000 |
| ductless mini split | $7,000 to $15,000 |
| heat pump | $7,000 – $14,000 |
HVAC cost breakdown
Without adding labor costs, which typically cost $75 to $150 per hour, the average HVAC unit costs between $3,000 and $4,500 for a small unit and up to $15,000 or more for a premium or high-efficiency unit.
| air conditioning unit | low cost | high cost |
|---|---|---|
| central air conditioner | $4,500 | $12,000 |
| ductless air conditioner | $4,000 | $15,000 |
| furnace | $3,000 | $10,000 |
| heat pump | $3,700 | $14,000 |
How to reduce HVAC installation costs
There’s no hiding that replacing your HVAC is expensive, but there are ways to reduce costs.
- Take advantage of rebate programs and government incentives. In 2026, local and state incentives will still exist, although fewer than they once were. Homeowners in states like New York and California can save thousands of dollars by upgrading to an energy-efficient HVAC system or heat pump.
- Do not oversize the unit. A larger HVAC unit does not mean more air conditioning. Instead, you need a system that is appropriately sized for your home. “You can’t just remove a 3-ton system and install a 4-ton system just because a customer says, ‘I just want more air conditioning.’ It doesn’t work that way,” says Gregory Milich, ARS HVAC expert.
- Don’t wait until an emergency occurs. If you wait until your HVAC system breaks down, you could end up paying higher emergency service fees or needing a complete replacement instead of a minor repair.
- Use a reliable vendor. TThe right contractor can be a local company or a large national chain, but make sure it’s a reliable company. Make sure your HVAC provider is licensed, insured, and has the proper permits. This will help prevent future problems.
