When homeowners ask me, “Mark, how much will a Goodman 2.5 Ton AC really cost me?” my answer is always: “It depends—but let me break it down.”
A lot of folks see the equipment price online and assume that’s the full cost. The truth is, the price tag on the box is only part of the story. To install a Goodman 2.5 Ton 13.8 SEER2 Northeast System (condenser model GLXS3BN3010 + air handler model AMST30BU1300) properly, you need to factor in equipment, labor, accessories, and long-term operation.
In this guide, I’ll walk you through what you should expect to pay, why the numbers vary, and how to calculate whether it’s worth the investment.
📦 Equipment Costs
The Goodman 2.5 Ton package itself is the starting point.
🔑 Base Equipment Price

👷 Labor Costs
Here’s where most of the cost comes in. Labor rates in the Northeast are higher than in many other regions.
🔨 Standard Labor
For a straightforward replacement (old system out, new Goodman 2.5 Ton in):
-
$2,500–$3,500
This covers:
-
Removal of old equipment.
-
Installation of condenser + air handler.
-
Line set brazing and refrigerant charging.
-
Electrical connections.
-
Startup testing.
🛠️ Common Extra Costs
-
Ductwork modifications: $500–$1,500
-
Electrical panel upgrade: $800–$2,000 (if your panel can’t handle new load)
-
Condensate pump (for basements): $200–$400
-
Permits/inspection fees: $100–$500
👉 In my installs, at least 30% of projects need some duct or electrical adjustment. Don’t assume the lowest bid includes these extras.
🧾 Average Installed Price
When you add it all up, most Northeast homeowners pay:
-
Low end (simple install): $4,500
-
Typical range: $5,000–$6,500
-
High end (complex install): $7,000+
👉 The wide range comes from home-specific factors—age of ductwork, accessibility of install site, and whether you’re replacing vs. building new.
⚡ Long-Term Operating Costs
The upfront cost is just the beginning. What really matters is what you’ll spend (or save) every summer.
📉 Energy Usage Calculation
Formula:
For a 2.5 Ton (30,000 BTUs) Goodman 13.8 SEER2:
-
Watts/hour: 30,000 ÷ 13.8 = ~2,174 watts (2.17 kW)
-
Annual cooling hours (Northeast): ~1,200 hrs
-
Electricity rate (Northeast avg): $0.20/kWh
Annual Cost:
2.17 × 1,200 × $0.20 = $521 per year
🔄 Comparison to Older Units
-
Old 10 SEER unit: ~$718/year
-
New 13.8 SEER2 unit: ~$521/year
-
Savings: ~$197/year
Over 10 years = ~$2,000 saved
Over 15 years = ~$3,000 saved

🧹 Maintenance Costs
Even the best Goodman won’t last if you ignore upkeep.
-
Filter replacements: $60–$120/year
-
Annual maintenance (pro service): $100–$200
-
Coil cleaning (every 2–3 years): $150–$300 if done professionally
👉 Skipping maintenance is the fastest way to turn a $5,000 system into a $10,000 headache.

📈 Lifetime Value
A Goodman 2.5 Ton 13.8 SEER2 system typically lasts 15–20 years with proper care.
🧮 Return on Investment (ROI)
-
Upfront cost: ~$5,500 (average)
-
Lifetime energy savings vs. 10 SEER: $2,500–$3,500
-
Comfort improvements: Priceless (lower humidity, quieter operation, consistent cooling).

Don’t forget incentives.

Check your local utility or DSIRE rebate database.
🧰 Mark’s Pro Tips for Budgeting
-
Get at least 3 quotes. But compare apples to apples—does the quote include ductwork, permits, and electrical?
-
Don’t choose cheapest by default. A $1,000 cheaper install that skips duct sealing can cost you thousands in efficiency losses.
-
Think 10+ years, not just year 1. Energy savings, maintenance, and warranty value matter more than sticker price.
-
Budget for annual maintenance. $150/year keeps warranties valid and systems running smooth.
-
Ask about financing. Many Goodman dealers offer 0% financing for 12–24 months.
✅ Bottom Line: What You’ll Really Pay
Here’s how I explain it to homeowners:
-
Upfront Equipment + Labor: $4,500–$6,500
-
Annual Energy Bill (13.8 SEER2): ~$521
-
Savings vs. old unit: ~$200/year
-
Maintenance: ~$150/year
👉 A Goodman 2.5 Ton system isn’t just an appliance—it’s a 15–20 year investment. Installed right, it saves money, improves comfort, and pays for itself over time.
