Most HomeCloud HVAC replacements
$8,900 to $10,100
Middle job $9,200. Based on a statistically significant number of HomeCloud jobs, January 2025 to October 2026.
Most HomeCloud jobs that replaced one full heating and cooling system cost $8,900 to $10,100. Where yours lands depends on the type of system, its size, how efficient it is, and how easy the equipment is to reach.
When the problem is one part on a system that's otherwise in good shape, a repair is usually the better spend.
HomeCloud is a licensed general contractor. We price the replacement by system type and size and manage the install from start to finish. Licensed HVAC technicians do the work.

What affects the price
- Type of system
- A heat pump, a gas furnace paired with an air conditioner, and a packaged unit that sits outside all cost differently. Switching from one type to another adds work.
- Size
- Systems are sized to the home, measured in tons of cooling. A bigger home, or one that holds heat or cold poorly, needs a bigger system. Sizing matters: a system that's too big or too small costs more to run and wears out faster.
- Efficiency
- More efficient equipment costs more up front and less to run. For air conditioners and heat pumps, efficiency is shown as a SEER2 rating: the higher the number, the more efficient.
- Where the equipment sits
- Indoor units in a tight attic, crawl space or closet take more time to take out and put in.
- Ductwork, wiring and venting
- Worn ductwork, a new electrical circuit, a new condensate line or changes to the furnace venting add to the job. See ductwork repair.
- Number of systems
- Many larger homes have two systems, often one for each floor. Each system is priced on its own.
Repair or replace?
An older system can keep running for a while, but repairs tend to come more often as it ages, and money spent on an old unit may be better put toward a new one. If the system is near the end of its life and needs a major part, replacement is often the better spend.
When a HomeCloud evaluation finds a unit at or past its expected life, the report says so, so you can plan for it before it fails. Reports also flag a system that didn't produce cold air and problems like rust, leaks and clogged condensate lines.
An old system isn't an emergency by itself. It's a cost to plan for, and knowing it up front helps when you're buying or selling. To find your system's type and age, see what kind of HVAC system do I have?
How HomeCloud does it
- 1
Evaluate the system
We record the equipment, its age and condition, and the ductwork and thermostat it connects to.
- 2
Size and scope
We match the new system to the home, and note any ductwork, drain or electrical work it needs.
- 3
Install
Old equipment is removed and the new system is installed, connected and started up.
- 4
Test the system
The system is tested for heating and cooling.
Common questions
Who registers the warranty on the new equipment?
You do. HomeCloud doesn't register equipment warranties. Many makers ask you to register new equipment to get the full warranty, so keep the paperwork and register soon after the install. See the best HVAC brands for how warranties differ.
Is sales tax charged on a new HVAC system?
In North Carolina, installing or replacing a central air system is a capital improvement, so you aren't charged sales tax on the job. Repairs and part replacements are taxed. See how sales tax works on home repairs.
Should the indoor and outdoor units be replaced together?
Usually, yes. The indoor and outdoor parts are designed to work as a matched set, and the refrigerants systems use have changed over the years, so an older indoor coil may not work with a new outdoor unit.
Can I just repair my old system?
Often, if the problem is one part and the rest of the system is in good shape. See HVAC repair and service.
Are there rebates or tax credits for a new system?
Not the federal tax credit. The Energy Efficient Home Improvement Credit, which helped pay for heat pumps, central air conditioners and furnaces, only covers equipment installed by the end of 2025, according to the IRS. State and utility rebates are still offered in some areas, but they change often and many require an approved or participating contractor, so check the program page before you sign. In North Carolina, Energy Saver North Carolina offers rebates to households earning less than 150% of the area median income (since September 2026, its appliance rebates no longer cover switching from gas to electric equipment), and Duke Energy offers home improvement rebates through participating contractors. In Georgia, the state's Home Energy Rebates are based on household income and expected energy savings, and Georgia Power's Home Energy Improvement Program offers its customers rebates for switching to a heat pump, attic insulation, air sealing and duct sealing. In Texas, the state's home energy rebate programs had not launched as of August 2026, according to the Texas Comptroller. In the Oncor area around Dallas-Fort Worth, Take A Load Off, Texas offers HVAC and insulation incentives through participating service providers, usually from January to November.
Can I pay for a new system over time?
