How Much Does HVAC Repair and Replacement Cost in the U.S.?
Most HVAC repairs in the U.S. run between $150 and $650 per visit, while a full system replacement typically falls somewhere between $3,800 and $10,500 depending on the equipment. The real number for your home depends on the type of system, its size, and whether the ductwork needs attention too.

What actually changes the price
HVAC pricing is never a single number because it depends on several things stacked together. The type of equipment matters most: a central air conditioner, a gas furnace, a heat pump, and a ductless mini-split all have different unit costs and installation requirements, and heat pumps in particular tend to run higher since they handle both heating and cooling. The size of the system, measured in tonnage for cooling or BTUs for heating, also has to match your home's square footage, so a contractor undersizing or oversizing the equipment isn't just a comfort problem, it affects the price too.
The condition of what you already have plays a role as well. If the existing ductwork is sound, a straight equipment swap is far cheaper than a job that also requires sealing, resizing, or replacing sections of duct. Electrical work can add to the total too, since some higher-efficiency units need an upgraded circuit or a new disconnect box.
Timing affects price more than most homeowners expect. Emergency calls during the first heat wave or cold snap of the season often carry higher rates than a scheduled appointment in the shoulder months of spring or fall, simply because demand for technicians spikes at the same time everyone's system fails.
Typical cost by service type
General ranges reported across the U.S. HVAC industry. Your actual quote will depend on your equipment, your region, and the condition of your existing system.
| Service | Typical price range |
|---|---|
| AC repair, single visit | $150–$650 |
| Furnace repair, single visit | $150–$600 |
| Seasonal tune-up or maintenance visit Most common | $75–$200 |
| Central air conditioner replacement (unit and install) | $4,500–$9,000 |
| Furnace replacement (unit and install) | $3,800–$8,500 |
| Heat pump replacement (unit and install) | $5,000–$10,500 |
| Ductless mini-split installation, single zone | $3,000–$7,000 |
| Ductwork repair or replacement, whole home | $1,500–$5,500 |
Figures are typical ranges based on published home-services cost guides (Angi, HomeAdvisor, Forbes Home, and similar), not guarantees. Replacement costs vary the most, since brand, efficiency rating, and the complexity of the installation all move the final number. Before agreeing to any work, confirm pricing directly with the provider.
Repair, replace, or upgrade
A single repair
Makes sense when the system is otherwise reliable and the issue is isolated, a failed capacitor, a bad igniter, a refrigerant leak. Most repairs are a same-day fix once the part is identified.
Like-for-like replacement
The standard option once a system is past 12 to 15 years old or has needed several repairs in a short span. A contractor installs equivalent new equipment sized to match your home.
Efficiency upgrade
Worth considering if you're replacing anyway. Higher-SEER air conditioners and higher-AFUE furnaces cost more upfront but lower monthly utility bills, and some regions offer rebates that offset part of the difference.

Is it worth repairing an HVAC system over 15 years old?
Usually not, unless the repair is minor and inexpensive. Most residential HVAC equipment is designed to last 12 to 20 years depending on the type, and older systems tend to need more frequent repairs while also running less efficiently than current models. A common rule of thumb is to compare the repair cost to the cost of replacement: if a repair costs more than roughly a third to half of a new system, replacement is usually the better long-term value.
Does homeowners insurance cover HVAC repair or replacement?
Generally no, unless the damage comes from a covered peril like a fire, lightning strike, or a fallen tree. Routine breakdowns from age or wear are treated as a maintenance issue, similar to a roof that wears out over time, and are almost always an out-of-pocket cost.
Why do HVAC replacement quotes vary so much between companies?
Price differences usually come down to the equipment brand and efficiency rating, whether ductwork work is included, the warranty terms offered, and local labor rates. Two contractors quoting the same visible job can land far apart if one is including duct sealing or a better warranty and the other isn't. Getting more than one detailed quote is the most reliable way to see the real range for your home.
How long does a full HVAC system replacement take?
A straightforward like-for-like swap, where the ductwork and electrical are already in good shape, typically takes one full day. Jobs that also involve duct modifications, electrical upgrades, or converting from one system type to another (adding ductwork for a first-time central system, for example) can take two to four days.
