Evaporator Coil Replacement in Houston, TX
A failed evaporator coil freezes your system, leaks refrigerant indoors, and stops your AC from cooling — and a coil that matches your condenser matters more than most people realize. Pilo's replaces evaporator coils correctly. Call (713) 728-9776 for evaporator coil replacement in Houston.
Signs you need evaporator coil replacement
- Coil freezing over despite a clean filter
- Refrigerant leak traced to the indoor coil
- AC runs but can't reach temperature
- Water leaking from the indoor unit or air handler
- System is older and the coil has repeated leaks
What happens during the service visit
- 1We confirm the coil is the failure — checking airflow, filter, and charge before condemning it.
- 2We size a replacement coil matched to your condenser's tonnage and refrigerant.
- 3We recover refrigerant, swap the coil, and install a proper drain pan setup.
- 4We pressure-test, evacuate, and recharge to a weighed-in charge.
- 5We verify airflow, temperature drop, and drain function before we leave.
How pricing works
The minimum repair to get you running again right now.
We fix only the part that failed — the fastest, lowest-cost option to get your system back on today. It addresses the symptom, not the underlying wear that caused the failure, so it's best when you're planning to replace the system soon or need a short-term hold.
The repair that solves the root cause, not just the symptom.
We replace the failed component plus the connected parts that are wearing out next, so you don't pay for a second visit in a few weeks. It costs more than a Band-Aid up front but lasts longer and protects the rest of the system.
Smart Fix plus a full tune-up, inspection, and maintenance plan.
Our most complete option — the Smart Fix repair, a full system tune-up and safety inspection, and enrollment in our maintenance plan so the repair stays protected and the next problem gets caught early. Best when you want the issue solved and prevented.
Every repair starts with one flat diagnostic fee, and that fee is credited 100% toward your completed repair — so you never pay twice for the same visit. Most common repairs (capacitors, contactors, drain clearages) run $150–$400; larger fixes like compressors or coils cost more. You'll see a flat-rate quote before any work starts.
Repair or replace — an honest recommendation
A single coil leak on a younger, in-warranty system is worth repairing or replacing the coil. Multiple leaks on a 10+ year system usually mean the metal is thinning throughout — a replacement system with a fresh coil and warranty is typically the better long-term call. We'll show you both.
