What Does It Cost to Replace an HVAC System?
Your HVAC system can be very expensive running from $1,600 to $10,000 for a new unit.
The total cost of a heating and cooling system for your home is determined by the sum of its parts. Here is a brief breakdown.
Cost of an HVAC System
Depending on the size of your home, the degree of energy-efficiency you desire, and the quality of the system, the various parts of an HVAC system can vary quite a bit.
- Central air conditioner: $4,800 to $10,000
- Gas Furnace: $1,600 to $8,000
- Heat Pump: $4,600 to $10,000
This cost range is based on a 1,600 sq. ft. home and a three ton HVAC unit.
The Cost of Replacing an HVAC Unit
The cost of your HVAC unit will depend on the type. And, costs vary within each type of HVAC system both for the unit itself and for things like the cost of installation.
Cost of a Central Air Conditioning System
The price range for central air conditioning generally runs between $4,800 and $10,000. The less-expensive models on the lower end, unfortunately, tend to be less energy-efficient and cost more than you might think in the long run. The mid to high-end units cost more up front but their energy-efficient features save you money over time.
3.0 Ton AC Unit
- Economy model: $4,800 to $6,800
- Mid-price model: $6,000 to $8,400
- High-price, high efficiency models: $7,200 to $10,000
Not only will you save more money in the long run with a better model but you will be more comfortable over the years with a high-efficiency A/C unit. The top models get AFUE (Annual Fuel Utilization) ratings of around 97.3%.
Cost of a Heat Pump
New heat pumps range in cost from $4,800 to $10,000. This is a unit that both cools and heats your home. Because they are very energy-efficient they can help reduce your energy costs by as much as 60%!
3.0 Ton Heat Pump
- Economy model: $4,800 to $6,800
- Mid-price model: $6,000 to $8,400
- High-efficiency, high cost models: $7,200 to $10,000
Be aware that heat pumps are for moderate to mild climates. If you live in the far north you can use your heat pump at the beginning and end of winter to heat your home but you will need a gas furnace when temperatures fall below freezing.
Cost of Installing an HVAC System
Buying an HVAC unit is the first step and installation is the second. Make sure to add the cost of installation when considering your budget for an HVAC system. Installation costs vary with the size of your home (space to be heated and cooled), the type of unit you choose, and the HVAC contractor you use.
Installation of your HVAC system can run from $1,800 to as high as $10,500 depending on the amount of work to be done. Adding new ductwork or gas lines are common reasons to see costs on the high end.
Typical Installation Costs
- Installing an air conditioner: $1,800 to $10,500
- Installation of a gas furnace: $1,800 to $4,000
- Heat pump installation: $2,900 to $6,000
Costs vary according to the work needed and who does the work. Make sure to get an estimate before starting and if you need help finding an HVAC contractor, feel free to ask us for advice.

What is a heat pump system?
Furnaces burn fuel to heat the air around them, which is then circulated through the home. Unlike furnaces and boilers, heat pump systems do not create heat. Instead, they transfer heat from one area to another. Because they do not create heat, these systems use less energy than furnaces and boilers do.
In addition to heating, heat pump systems are also used to cool homes. They move heat out of the home to lower indoor temperatures. Heat pumps are used as a combination heating and cooling system, or in addition to conventional heating and cooling equipment.
FREQUENTLY ASKED QUESTIONS
The price will depend upon your home’s size and the heat pump’s rating. Prices can range from around $700 for ductless mini split systems up to $13,000 for a geothermal heat pump system, not including installation.
The cost for heat pump installation also depends on the size of the unit and whether it is a single-room or whole-home system. A single-room air-to-air system can cost as low as $500, including installation. Whole-house units, on the other hand, range in price from $2,500 to $7,500, including installation. Geothermal heat pumps typically require excavation to install, which adds several thousand dollars to the cost.
The type of heat pump you select, the climate where you live and the temperature you set at home will all impact the cost of running a heat pump. A highly-efficient model could save you 30% to 40% on your energy bill.
