Hey folks, Mike here. If you’ve ever been told your A-Coil (that’s your indoor evaporator coil) needs replacing, you probably had the same reaction most homeowners do:
“Wait—what’s an A-Coil, and why does it cost so much?”
I get it. The A-Coil isn’t the part you see outside humming away. It’s tucked inside your air handler or furnace, quietly doing the heavy lifting. But when it fails, you’ll feel it—in your comfort and in your wallet.
4 Ton Horizontal Goodman Cased Coil with Built-in TXV - CHPTA4830C3
So let’s break it down: in 2025, what does a Goodman A-Coil really cost? I’ll walk you through the equipment price, labor charges, hidden extras, and even the long-term energy savings you can expect. By the end, you’ll know exactly how to budget without getting blindsided.
📦 1. Equipment Cost: The Coil Itself
First, the basics: the Goodman CHPTA4830C3 horizontal cased coil is designed for 3.5–4 ton systems and is R-32 compatible.
Average 2025 Price Range
-
$600–$1,200 for the coil itself.
Factors That Affect Coil Price
-
Size/Tonnage: Bigger homes = bigger coils.
-
Cased vs. Uncased: Cased coils (like this one) cost more but are easier to install.
-
TXV Included: Thermal expansion valves (built-in with Goodman) improve efficiency.
-
Refrigerant Type: R-32 compatibility adds value in 2025 since R-410A is being phased out.
📖 Reference: Goodman – CHPT Series Coils
Mike’s advice: “If you’re replacing in 2025, don’t buy yesterday’s R-410A-only coils. Go R-32 ready—it’ll save you headaches later.”
🛠 2. Labor Cost: Installation & Replacement
The coil is only half the story. Installing it properly takes time, skill, and sometimes a bit of ductwork magic.
Average Labor Cost in 2025
-
$500–$1,200 depending on complexity.
Why Labor Costs Vary
-
Accessibility – Basement installs are easy. Crawlspaces or attics? Not so much.
-
Drainage Setup – Proper slope and drain pan access can take extra work.
-
Refrigerant Lines – If old lines need re-brazing or rerouting, labor climbs.
-
Duct Modifications – Even a few inches of mismatch can mean cutting and sealing.
-
Tech Skill Level – Experienced HVAC techs charge more, but save time and reduce mistakes.

Mike’s note: “If your coil’s in a crawlspace, expect the bill to go up—nobody likes crawling around with a torch and refrigerant lines.”
📊 3. Total Installed Cost
So what’s the all-in number you should plan for?
Typical 2025 Range
-
$1,100–$2,400 total installed cost.
Breakdown
-
Equipment: $600–$1,200
-
Labor: $500–$1,200
-
Misc. parts (drain line, fittings, insulation): $50–$150
Examples
-
Best Case: Easy basement install with good access → ~$1,200.
-
Mid Range: Attic or closet with some duct/drain adjustments → ~$1,500–$1,800.
-
High End: Crawlspace or tight utility closet with refrigerant rework → $2,000+.

⚡ 4. Energy Use & Efficiency Impact
Here’s the part most homeowners miss: a new coil can actually save you money long-term.
Why?
-
A clean, properly matched coil improves airflow and reduces compressor strain.
-
TXVs regulate refrigerant more efficiently than old piston-style coils.
-
Oversized or dirty coils can increase energy consumption by up to 30%.
📖 Reference: Energy.gov – AC Maintenance
Example Savings
-
Average U.S. cooling bill: ~$900/year.
-
Efficiency gain from new coil: ~10–15%.
-
Annual savings: $90–$135.
-
Over 10 years? That’s $900–$1,350 back in your pocket.
Mike’s take: “That’s basically paying for the labor side of the install just from lower bills.”
🔧 5. Hidden & Extra Costs to Watch
Don’t let these sneak up on you:
-
Refrigerant Charge: R-32 systems may need new refrigerant → $150–$400.
-
Ductwork Modifications: Even small cuts and seals add $200–$500.
-
Drain Pan Replacement: If rusted or cracked, budget another $100–$300.
-
Warranty Extensions: 10-year extended warranties can cost $100–$300.

📉 6. The Cost of NOT Replacing a Bad Coil
Delaying coil replacement can actually cost more:
-
Higher Energy Bills – Dirty or leaking coils drive up usage.
-
Reduced Comfort – Poor airflow, humidity issues, uneven cooling.
-
Compressor Damage – A struggling coil stresses the system. Compressor replacement = $2,500+.
-
Water Damage – Leaks from drain pan or frozen coils can cause ceiling or wall repairs.
Mike’s advice: “A $1,500 coil replacement now beats a $5,000 repair bill later.”

💡 7. Mike’s Budgeting Advice
Here’s how I help homeowners plan smart:
-
✅ Get 3 quotes – Prices vary widely.
-
✅ Ask for line-item breakdowns – Know what’s equipment vs labor vs extras.
-
✅ Confirm compatibility – Match coil to condenser (SEER2, refrigerant type, tonnage).
-
✅ Think long-term – Don’t just chase the cheapest coil. Efficiency and durability matter.
-
✅ Plan for the hidden costs – If your space is tight, budget for duct tweaks.
Mike’s bottom line: “Spend a little more upfront on the right coil, and you’ll save on energy, repairs, and headaches for years to come.”
