Air Conditioner Installation
Efficient Cooling, Professionally Installed
A new air conditioner is a major investment in year-round comfort and efficiency. Whether you're replacing an aging system or installing central air for the first time, the right unit, correctly sized and installed, keeps your home cool and your energy bills in check.
Sizing is everything. A good HVAC pro calculates the right capacity for your home rather than guessing, since an oversized or undersized unit wastes energy and wears out faster. They'll also weigh efficiency ratings against your budget.

Did You Know?
An improperly sized AC unit can short-cycle and wear out years early, which is why professional load calculation matters as much as the equipment itself.
Air Conditioner Installation Cost. How Much Do Projects Cost?
Most projects run between $6,000 and $15,000. The average price is typically around $8,500. These figures cover replacing a central AC in a home that already has usable ducts, equipment and labor included. New or replacement ductwork is not included and adds $1,500 to well over $20,000, which is why that row runs past the top of the range, and a quote near $3,800 to $5,650 is an outdoor condenser swap only rather than a full system.
Typical duration: 1 to 3 days
| Cost Factor | Typical Range | Notes |
|---|---|---|
| System size and tonnage | $7,600-$15,000 full system installed | Sized to your home's cooling load; at the condenser alone each added ton adds about $600 |
| Efficiency rating (SEER2) | $7,600-$10,100 at 16 SEER2 up to $12,400-$14,900 at 20 SEER2 | Mid-tier 17 SEER2 systems land at $8,700-$11,000 installed |
| Ductwork and installation complexity | $1,500-$20,000+ added for new or replacement ducts | Rarely needed on a straight replacement, but a first-time install in a home with no ducts lands well above the summary range |

Signs You Need Air Conditioner Installation
- An AC over 12 to 15 years old
- Frequent, costly repairs
- Rising energy bills
- Uneven or inadequate cooling
- Installing central air for the first time
Is It Right For You?
Who It's For
- Homeowners replacing an old or failing AC
- Anyone adding central or ductless cooling
Who It's Not For
- Systems that a repair would restore
- Homeowners better served by a heat pump for both heating and cooling
What to Watch Out For
New AC systems are a major purchase
Homes needing new ducts pay considerably more
Alternatives to Consider
| Alternative | Better When | Worse When |
|---|---|---|
| Repairing the existing unit | Cheaper short-term | Not worth it on an old, failing system |
| Heat pump | Handles heating and cooling | Higher upfront cost but may consolidate systems |
Is It Worth It?
For an aging or failing AC, replacement is worth it, delivering reliable comfort and lower energy bills that offset the upfront cost over time.
Questions to Ask Your Pro
- What size and efficiency unit is right for my home?
- Is my existing ductwork in good shape?
- Would replacing the furnace at the same time save money?
Frequently Asked Questions
Replacing a central AC in a home that already has ducts costs $6,000 to $15,000 installed, averaging around $8,500, depending on system size and efficiency. If the home needs new or replacement ductwork, add $1,500 to well over $20,000 on top of that.
Sizing depends on your home's square footage, insulation, and climate, and a pro calculates the right capacity to avoid an oversized or undersized unit.
Yes. A baseline 16 SEER2 system installs for about $7,600 to $10,100, while a premium 20 SEER2 variable-speed system runs $12,400 to $14,900, and the higher-efficiency unit lowers your bills over the system's life.
A new or replacement duct system runs $1,500 to well over $20,000 on top of the equipment, so a first-time install in a home with no ducts costs far more than a straight replacement.
Often yes. Replacing both at once lowers combined labor costs and ensures a matched, efficient system.
