Is Your Home Not Staying Cool? Jerry’s is Here to Help!
Is your air conditioner frozen solid, or were you just told you have a “leaking coil”? The indoor evaporator coil (often called an A-coil) is one of the most critical and expensive components in your air conditioning system. Located inside your air handler or attached to your furnace, it absorbs heat and humidity from your home’s air. When it fails, leaks, or becomes severely fouled with dirt, your entire AC system loses the ability to cool effectively.
Jerry’s Plumbing, Heating & Air Conditioning provides expert evaporator coil cleaning, repair, and replacement throughout Santa Maria, Orcutt, Nipomo, and the Central Coast. Our licensed HVAC technicians accurately diagnose coil problems and restore your system’s cooling performance without the high-pressure sales tactics.
Why Choose Jerry’s for Evaporator Coil Services?
Evaporator coil work is highly technical. It requires an EPA Section 608 certification, expensive refrigerant recovery equipment, and the expertise to properly braze, seal, and pressure-test the system.
- Precision Replacements: We handle the complete process, from safe refrigerant recovery and precise coil matching (cased or uncased) to the final system vacuum and factory-spec recharge.
- All Brands Serviced: We work with all major coil and AC manufacturers, including Carrier, Trane, Lennox, Aspen, and ADP.
- Second Opinions: If another company quoted you an outrageous price for a new coil, call us. We provide honest, upfront diagnostics before any work begins.
Because the coil is hidden inside a dark metal cabinet, problems often go unnoticed until the system completely breaks down. Call us if you notice:
- Warm Air from the Vents: A frozen, fouled, or leaking evaporator coil is one of the most common reasons an AC runs without cooling effectively.
- Ice Buildup on the Coil or Copper Lines: Restricted airflow or a refrigerant leak causes the coil to drop below freezing, forming ice that shuts down cooling.
- Frequent Refrigerant Leaks: Evaporator coils develop pinhole leaks over time, particularly in homes with high indoor humidity. Low refrigerant is often traced back to a coil leak.
- Reduced Airflow: A heavily fouled coil restricts airflow through the system, reducing both efficiency and your home’s cooling capacity.
- Hissing or Bubbling Sounds: Sounds near the air handler can indicate refrigerant escaping from a cracked or corroded evaporator coil.
- Higher Energy Bills: A dirty or failing evaporator coil forces your system to work significantly harder, consuming more electricity to achieve the same cooling.
A clean evaporator coil is the single most important factor in your AC system’s efficiency and lifespan. As your AC runs, the coil gets wet with condensation. When dust bypasses a cheap air filter, it turns into a thick sludge on the wet coil, reducing heat transfer and promoting mold growth.
Annual coil cleaning, performed during a Jerry’s seasonal HVAC tune-up, removes this sludge using specialized, non-acidic foaming cleaners. This simple maintenance step prevents the severe corrosion that leads to premature refrigerant leaks and early replacement. It is one of the highest-return investments you can make in your home’s comfort.
Can an evaporator coil be repaired, or must it be replaced?
If the leak is located on an accessible external copper joint or the thermal expansion valve (TXV), it can often be brazed and repaired. However, if the leak is caused by formicary corrosion deep within the aluminum fins (which is the most common failure), the leak cannot be permanently patched. In this case, the entire coil must be replaced to ensure system reliability.
How much does it cost to replace an AC evaporator coil?
The cost depends on the tonnage of your system, the brand, whether the coil is cased or uncased, and the amount of replacement refrigerant required. If your AC system is less than 10 years old, the coil replacement may be covered under your manufacturer’s parts warranty, leaving you responsible only for the labor and refrigerant.
Why does my evaporator coil keep freezing?
An evaporator coil freezes for two main reasons: a severe lack of airflow (usually caused by a completely clogged air filter or a dead blower motor) or a low refrigerant charge due to a leak. If your system is frozen, turn the AC to “OFF” and switch the fan to “ON” to thaw the ice, then call a professional immediately.
The evaporator coil works in tandem with other critical indoor components. Learn more about how we service your entire system:
