If you're thinking about installing central air (or upgrading your existing system), then what we’re about to cover matters. Because when you ask questions like “cost of central air for 1,000 sq ft house,” “cost of central air for 2,000 sq ft house,” or “how much is a 5‑ton AC unit installed,” you’re really trying to understand how much value you’re getting — not just how many dollars you’re spending.
Today I’ll take you through:
-
The key pricing benchmarks for central air systems by home size.
-
How the Goodman 3 Ton 14.5 SEER2 R‑32 bundle serves as a smart reference point.
-
How to adjust those benchmarks for your home’s unique needs.
-
What upsells, hidden costs, and installation details you need to watch.
-
How to use this info to negotiate confidently with contractors.
By the end of this blog, you’ll know what a reasonable budget is for your home size — whether it’s a cozy 900 sq ft bungalow or a 3,000 sq ft family home — and you’ll feel empowered to ask the right questions. Let’s get started.
1. Pricing Benchmarks by Home Size: What You’re Likely to Pay
Understanding what others are paying gives you context for what you should expect. Below are benchmark numbers based on home size, showing typical ranges for installation of central air (equipment + labor) excluding major ductwork overhaul unless noted.
• Homes around 900‑1,000 sq ft
For a very modest home (900–1,000 sq ft), you might see:
-
“Cost of central air for 900 sq ft house” around $4,500 to $7,000 installed. (According to one cost table: 1,000 sq ft ≈ $4,500‑$7,000) (HomeGuide)
-
If your home already has ductwork and standard install conditions, you might hit the lower end.
• Homes around 1,200 sq ft
Looking at “cost of central air for 1,200 sq ft house” or “HVAC unit cost for 1,200 square feet”:
-
Rough installed cost might range $5,000 to $7,500, assuming moderate efficiency, workable ducts.
-
If you upgrade to higher efficiency or need extra labor, expect the upper end.
• Homes around 1,500–1,600 sq ft
For “cost of central air for 1,500 sq ft house” or “AC unit for 1,500 sq ft home cost”:
-
Typical cost installed might be $6,000‑$9,000 or more.
-
These homes often require ~2.5‑3 ton systems (though this depends on insulation, layout, climate).
• Homes around 2,000 sq ft
Looking at “cost of central air for 2,000 sq ft house”:
-
Many guides suggest that for a 2,000 sq ft home you might budget $7,000‑$11,500, including roughly average equipment & installation. (NerdWallet)
-
If your ducts are in good shape and installation is straightforward, you may hit the lower end; but large homes often bring complexity.
• Larger homes (e.g., 3,000 sq ft or more)
For “AC unit for 3,000 sq ft house cost”:
-
The cost can climb substantially. For example, one source puts a 4,000 sq ft home replacement around $17,389 average, with a range ~$12,988‑24,970. (This Old House)
-
For 3,000 sq ft you might expect somewhere in the multi‑$10,000 range, depending on tonnage, zones, ductwork, high efficiency.
• “How much is a 5‑ton AC unit installed?”
Because large homes often require 4‑ton, 5‑ton systems (or multiple smaller units), the installed cost for a 5‑ton unit will reflect higher capacity and likely more labor. Some installer forum posts show ~10K or higher for 5‑ton installs. (Reddit)
Summary Table
| Home size | Typical installed cost range* |
|---|---|
| ~900‑1,000 sq ft | ~$4,500 ‑ $7,000 |
| ~1,200 sq ft | ~$5,000 ‑ $7,500 |
| ~1,500‑1,600 sq ft | ~$6,000 ‑ $9,000 |
| ~2,000 sq ft | ~$7,000 ‑ $11,500 |
| ~3,000 sq ft+ | ~$10,000+ (often much more) |
*These ranges assume existing ductwork in reasonable condition, typical 3‑4 ton systems, and standard installation conditions.
2. How the Goodman 3‑Ton 14.5 SEER2 R‑32 Bundle Fits In
Let’s anchor these benchmarks with a real product reference so you can see how a specific system maps to your budget. The product I’m referencing is the Goodman 3 Ton 14.5 SEER2 R‑32 Bundle (3‑ton outdoor condenser + matching indoor coil/handler in many cases).
Why this bundle is a useful benchmark
-
3‑ton capacity is common for homes ~1,500‑2,000 sq ft (though actual sizing must be determined by a Manual J load calculation).
-
14.5 SEER2 is moderate efficiency (higher than very entry level, less than ultra premium), making cost more moderate.
-
R‑32 refrigerant shows newer refrigerant technology (which helps future proof).
-
It simplifies matching indoor/outdoor components (reducing mismatch risks).
-
Equipment cost (equipment only) for this Goodman bundle can be in the ~$3,800 to ~$4,500 range (based on current online listings). For example: $3,867 equipment cost in one listing.
How it maps to your installed cost budget
Given typical installation multipliers (equipment + labor + minor ductwork changes), you can use this bundle to estimate your installed cost as follows:
-
Equipment cost ~ $4,000 (just a rough baseline).
-
Labor + installation + minor duct fixes might add ~$2,000‑$6,000 depending on complexity.
-
For a home in the size range ~1,500‑2,000 sq ft, total installed cost might land in the ~$6,000‑$9,000 range if everything goes smoothly (ducts in good shape, standard access).
-
If your home is smaller (1,000‑1,200 sq ft) using a 3‑ton bundle might be oversized or cost more than needed (unless specific conditions demand it) — you might expect lower tonnage.
-
Conversely, if your home is larger (2,500‑3,000 sq ft), this system might be undersized or you may need multiple units, pushing your cost up.
What this means for you
-
If your home is ~1,500 sq ft and you’re quoted ~$8,000 for this Goodman bundle + install, that is within the typical range and appears reasonable.
-
If you’re quoted $12,000+ for a similar spec system (same size & tonnage) you’ll want to ask what extra features or upgrade conditions drove the cost (ductwork overhaul? difficult access? premium controls?).
-
If you’re quoted $4,000 total installed for this bundle in a 1,500‑sq ft home and you have older ducts, you may be under‑quoting risk (maybe ductwork issues not addressed, warranty limited).
3. Adjusting for Your Home’s Unique Needs (Size, Ducts, Efficiency, Access)
While the benchmarks and bundle give you a starting point, the actual cost for your home can vary significantly. Here are the key factors and how to adjust your budget:
Home size and tonnage
-
Smaller homes (~1,000‑1,200 sq ft) may only need a 2‑ton or 2.5‑ton system. According to one cost table: for 1,000 sq ft, cost might track ~$4,500‑$7,000.
-
Larger homes (~2,500‑3,000 sq ft) may need 4‑ton or 5‑ton systems (or multiple smaller systems). From one source: homes over 2,500 sq ft might cost $8,500‑$13,500+ for AC replacement.
Ductwork condition and access
The condition of existing ducts – their size, quantity of leaks, insulation, layout – can dramatically affect cost.
-
If you need entirely new ductwork you might add thousands in cost; one guide quotes new ductwork could run $1,000‑$2,700 for a 1,000 sq ft size, and even more for larger homes. (Angi)
-
Tight access (attics, crawl spaces, second story installs) raises labor cost.
-
If your ducts are in good shape then your install cost leans lower in the benchmark range.
Efficiency and system tier
-
Higher SEER2 ratings, better components (variable‑speed motors, premium filtration), and top brands cost more upfront but may save energy long‑term.
-
One cost breakdown: for central AC, average cost for installing a new central system ranged ~$3,300‑$7,800 for a 3‑ton 2025 model in a 2,000 sq ft home. (HVAC.com)
-
If you opt for ultra high efficiency (and premium brand) you may push costs toward the high end of the range.
Home layout, insulation, climate
-
Homes with high ceilings, large windows, poor insulation, or extreme climate will require more capacity/effort — more cost.
-
If your home is simple shape, moderate climate, efficient building envelope — you may stay toward the lower end.
Labor, region, timing, brand
-
Labor rates vary greatly by region (big cities vs rural), and by time of year (peak summer may cost more).
-
Brand matters: Some premium brands cost more for equipment and may have higher service costs.
-
Installation quality matters: a cheap install may cost less upfront but cost more over system life.
4. Real‑World Scenarios: Mapping Your Home to Budget Ranges
Let’s walk through a few real‑world scenarios and map what you might expect.
Scenario A: 1,000 sq ft home
You own a small home (1,000 sq ft), decent insulation, existing ductwork in good shape.
-
You might expect a 2‑ton system.
-
Benchmark range: ~$4,500‑$7,000 installed (based on cost table for 1,000 sq ft)
-
If your quote for the Goodman bundle (3‑ton) comes in at ~$8,000, that might be higher than needed unless special conditions exist (poor insulation, tricky ductwork, premium features).
-
If the quote is $5,500 and includes all major components, that’s in the reasonable ballpark.
Scenario B: 1,500 sq ft home
You have 1,500 sq ft, maybe a 2‑story but moderate layout, decent ducts.
-
You likely need ~2.5‑3 ton.
-
Benchmark range: ~$6,000‑$9,000 installed.
-
If you choose the Goodman 3‑ton bundle and get a quote for ~$7,500 installed, that is reasonable.
-
If you’re quoted $4,000 (really low), question ductwork or brand/efficiency. If you’re quoted $12,000 (high), ask about premium upgrades and make sure you’re getting your money’s worth.
Scenario C: 2,000 sq ft home
You own a 2,000 sq ft home with average insulation and ductwork.
-
You might need ~3‑3.5 ton.
-
Benchmark: ~$7,000‑$11,500 installed.
-
If the quote for the Goodman 3‑ton bundle comes in at ~$9,000 and includes modest duct repairs, that seems fine. If it’s $13,000+, dig into what’s driving the cost.
Scenario D: 3,000 sq ft home
You have a large home (~3,000 sq ft), maybe multiple zones.
-
You might need a 4‑5 ton system (or two smaller systems).
-
Cost could easily reach $10,000+; for 4,000 sq ft one source lists ~$12,988‑24,970 installed.
-
In this scenario, your per‑square‑foot cost tends to be higher due to complexity.
5. How to Use These Insights When Getting Quotes
Savvy home shoppers ask questions and compare wisely. Use these steps in your process.
Obtain multiple quotes
-
Get at least 2‑3 quotes from licensed HVAC contractors.
-
Ensure each quote breaks out: equipment model, tonnage, SEER/SEER2 rating, indoor/outdoor match, labor, ductwork work, permit fees, disposal of old equipment.
Ask the right questions
-
“What tonnage and model are you proposing for my home size?”
-
“Does the quote assume my existing ductwork is in good shape? If not, how much extra will ductwork cost?”
-
“What is the SEER2 rating and refrigerant type of the system?”
-
“What is the brand and warranty of the equipment?”
-
“Are we installing a matched system bundle (indoor + outdoor)?”
-
“What is included in the labor? Will there be any hidden surcharges (locations, roof runs, tight access)?”
-
“Do you provide a Manual J load calculation so we know the size is right?”
Compare cost relative to home size
-
Use your home’s square footage and the benchmark ranges above to see if your quote is reasonable.
-
Example: If your home is 1,500 sq ft and quote is ~$12,000 for a 3‑ton system, you’re at the high end; ask what upgrades justify that difference.
-
If your home is 900 sq ft and quote is $8,000 for a 3‑ton system, question whether the size is necessary or whether there are inefficient parts of the install.
Value vs cheapest price
-
The lowest quote is not always the best value. Consider equipment brand, efficiency, warranty, and installation quality.
-
A properly installed system with moderate efficiency often beats a cheap system installed poorly or with minimal warranty.
Use per‑square‑foot rules of thumb
-
Some sources report cost per square foot for central air installation at roughly $3.00‑$7.50/ft² (for typical installs) with average around $5.25/ft².
-
That means for a 1,500 sq ft home: 1,500 × $5 = ~$7,500 as a ballpark.
Monitor unexpected cost drivers
-
Ductwork replacement or major repair adds in the thousands. One guide says new ductwork can run $20‑$45 per linear foot and total $600‑$9,000 depending on home size. (kliemannbros.com)
-
Obstructions, structural issues, upgrades (smart thermostats, zoning) also cost more.
-
Location/labor: high cost of living regions = higher install cost.
6. Why the Goodman Bundle Could Be a Smart Choice for Many Homeowners
Let’s connect back to the Goodman bundle and see why it’s a compelling option.
-
The bundle offers solid capacity and moderate efficiency — for many homes this is “just right.”
-
Because the equipment cost is moderate (~$4,000 equipment only) you’re not spending premium dollars for ultra efficiency unless you need it.
-
For homeowners whose home size fits ~1,500‑2,000 sq ft and with reasonable ductwork, you may get very balanced value: good comfort, moderate cost, good durability.
-
By choosing a system like the Goodman 3‑Ton 14.5 SEER2 R‑32 bundle and focusing resources on a quality installation, you may avoid overpaying for features you don’t need.
In short: this is a “good enough + well installed” approach rather than “premium + overkill + high cost.”
7. Final Thoughts & Your Savvy Shopper Checklist
As you move toward getting quotes or making decisions, here are the key takeaways:
✔ Use your home’s square footage as a starting point to set expectations.
✔ Don’t focus on equipment cost only — consider labor, ductwork, installation complexity.
✔ The “cost of central air for 1,000 sq ft/1,200 sq ft/1,500 sq ft/2,000 sq ft” ranges provided above give you realistic bands.
✔ Ask for full details in your quote (equipment model, tonnage, SEER2, duct condition) and don’t accept vague “up to code” statements without clarification.
✔ The Goodman bundle is a solid reference option — moderate cost, good performance — which makes it easier to compare other quotes.
✔ Beware of both extremes: super low quotes (may cut corners) and super high quotes (may be including premium features you don’t need).
✔ Remember: A well installed system that matches your home’s needs offers better long‑term value than an oversized or under‑sized premium system poorly installed.
