COIL REPLACEMENT — HOUSTON, TX
Evaporator & Condenser Coil Replacement Houston TX
Suspect a coil fault? Diagnose the issue before authorizing a repair.
Your AC keeps running low on refrigerant. You've already had it recharged twice. The reason it keeps losing refrigerant is a leaking evaporator coil — and topping it off again won't fix that. Air Zone Plus arrives fast and works clean.

What is Coil Replacement?
Your HVAC system has two coils: the evaporator coil inside your air handler or furnace, which absorbs heat from indoor air, and the condenser coil inside your outdoor unit, which releases that heat outside. Both coils can develop leaks over time — the evaporator coil from formicary corrosion caused by volatile organic compounds in indoor air, and the condenser coil from outdoor exposure and Houston's corrosive humidity.
Recurring refrigerant loss can have several causes; symptoms alone do not establish a coil fault. For an existing system, Air Zone Plus offers an on-site repair diagnosis for $125 for nonmembers, separate from the quoted repair charge and not credited or waived because the repair is approved. If you are planning a full system replacement instead, request a free project estimate. Ask about any membership benefit under your current agreement.
Coil replacement requires proper matching between the replacement coil and your existing equipment. A mismatched coil causes refrigerant charge problems, reduces system capacity, and can void the manufacturer warranty on other components. We source correctly matched coils and install them with full refrigerant recovery, filter drier replacement, system flush when needed, and a proper recharge.
Warning Signs to Watch For
Repeated Refrigerant Loss
If you have needed refrigerant added more than once in the past two years, a leaking evaporator coil is the most likely cause.
Frozen Coil
A heavily iced indoor coil — beyond normal condensation — often indicates a leaking evaporator coil or critically low refrigerant.
Reduced Cooling Capacity
A coil losing refrigerant gradually reduces your system's ability to cool. You notice it as the house struggling to reach set temperature on hot Houston days.
Climbing Energy Bills
A degraded coil forces your system to run longer to achieve the same cooling — driving up energy costs before the failure becomes obvious.
How We Handle It
1. Leak Detection
We use electronic leak detection equipment to confirm the coil is leaking and identify the location of the failure.
2. Replacement Assessment
We confirm the correct replacement coil for your system and give you honest repair vs. full system replacement guidance.
3. Coil Replacement
We recover refrigerant, replace the coil and filter drier, flush if contamination is present, and reassemble correctly.
4. Recharge and Test
We recharge to manufacturer specification, run a full performance test, and verify the system is operating correctly before we leave.

Frequently Asked Questions
How do I know if my evaporator coil is leaking?
If your AC has needed refrigerant added more than once, or if you have ice forming on the indoor unit repeatedly, a leaking evaporator coil is the most likely cause.
Should I replace just the coil or the whole system?
If your system is older and the coil replacement cost approaches that of a full system, replacement is often the smarter investment. We give you honest numbers for both options.
How long does coil replacement take?
Most evaporator coil replacements are completed in one day. We will give you a clear timeline after assessing your specific system.
Do you offer financing?
Yes — ask about financing options during your free estimate. We work with homeowners and businesses to find payment plans that fit their budget.
Are your technicians licensed?
Yes. All Air Zone Plus technicians are fully licensed, insured, and experienced across all major HVAC brands. License: TACLA 119805R.
