Evaporator Coil Replacement Cost in Chandler (2026): Two Worked Examples, Line by Line
What an evaporator coil replacement costs in a Chandler attic in 2026, shown as two worked examples with every line item. Warranty vs. out of warranty, why the refrigerant decides the total, and when to replace the system instead.
In Chandler, the evaporator coil is almost always in the attic. That one fact shapes the whole job. An evaporator coil replacement here runs $2,400 to $2,895 under warranty and $3,300 to $4,400 out of warranty. Those are our prices, not a national average. Below are two example jobs added up line by line so you can check any quote against them. If the leak hasn't been confirmed yet, start with a Chandler AC repair diagnostic.
The line items
Every coil job is built from the same five pieces.
| Line item | What it runs |
| --- | --- |
| New evaporator coil | $800 to $1,400 |
| Coil under manufacturer warranty | Coil is free; $50 to $100 processing |
| Labor on the refrigerant circuit | $1,595 |
| Attic drain re-pipe | $300 to $500 |
| R-410A refrigerant | $129 per pound |
The $1,595 covers recovering the old refrigerant, removing the old coil, a new filter drier, the brazing, a nitrogen pressure test, a deep vacuum and a weighed-in recharge.
Example 1: under warranty, leak caught early
Say a 9-year-old system in an Andersen Springs two-story. Registered when it was installed, so the parts warranty is still good. The leak was found at a spring tune-up before the charge dropped far.
| Coil | $0 |
| Warranty processing | $75 |
| Refrigerant-circuit labor | $1,595 |
| Attic drain re-pipe | $400 |
| R-410A top-off, 3 lb | $387 |
| Total | $2,457 |
Example 2: out of warranty, system ran empty
Now a 13-year-old system in south Chandler. It limped through August low on charge and finally quit. Nothing left to recover.
| Coil | $1,100 |
| Refrigerant-circuit labor | $1,595 |
| Attic drain re-pipe | $400 |
| R-410A full charge, 8 lb | $1,032 |
| Total | $4,127 |
Same house size. Same tonnage. $1,670 apart. The coil is part of the gap. The refrigerant is the rest.
Why timing changes the price
A system holds 5 to 15 pounds of R-410A. At $129 a pound, the charge alone runs from $645 to $1,935. If we catch the leak while most of the charge is still in the system, we recover it, reuse it and top off. If it ran empty, the whole charge is new.
That's the case for a $59.95 tune-up in spring. A leak found in April is a cheaper job than the same leak found in July.
Check the warranty before anything else
Many manufacturers cover parts for 10 years if the system was registered after install, and 5 if it wasn't. Chandler has a lot of homes from the mid-2000s to mid-2010s, which puts many of them right at that line.
We look up the serial number and tell you which side you're on before quoting. If a quote charges you for a coil and nobody checked the warranty, ask.
What the attic adds
- The drain. Pulling an attic coil means cutting and re-piping the PVC condensate line. If there's no float switch, this is when to add one. A backed-up attic drain ends up in the ceiling.
- Access. Tight hatches and truss work slow the job. That's in the labor number, not added on top.
- Two systems. Only the leaking one gets the coil. We check the other while we're up there.
Coil or whole system?
- Under 10 years, under warranty: replace the coil.
- 10 to 12 years: price both. A new coil on an old condenser is a mismatch in efficiency and remaining life.
- Past 12 years and out of warranty: a $4,000 coil is a big share of a new system. An upstairs 2 to 2.5 ton system runs about $6,500 to $9,500 installed. See AC replacement cost in Chandler.
Most of Chandler is SRP, so a full replacement can get Cool Cash. A coil alone doesn't qualify.

Questions people ask
How much does an evaporator coil replacement cost in Chandler?+
$2,400 to $2,895 when the coil is under manufacturer warranty and $3,300 to $4,400 when it isn't. Refrigerant at $129 per pound is the biggest variable.
Why is my coil quote higher than what I see online?+
National guides often assume a garage or closet coil with the refrigerant reused and no drain work. A Chandler attic coil needs the condensate drain re-piped and often a full recharge.
Is my evaporator coil under warranty?+
Many brands cover parts for 10 years if the system was registered and 5 if not. We check the serial number before quoting. Labor and refrigerant are not covered.
Can I just add refrigerant instead of replacing the coil?+
You can, but the leak is still there and you'll pay for the refrigerant again. We find the leak first and give you both numbers.
Does a new coil qualify for the SRP rebate?+
No. SRP Cool Cash requires a complete matched system, not a single component.
