Converting the Microchannel Coil in the Lennox® LCH156H4: Improve performance and reliability
Upgrading the Microchannel Coil in the Lennox® LCH156H4: Boost Performance and Reliability
Say goodbye to the common leakage problems found in the Lennox LCH156H4 rooftop unit and other OEM MCHX coils with a smart, cost-effective microchannel conversion.
When it comes to replacing commercial condenser coils, the Lennox LCH156H4 is one of the most commonly used units. However, many users face issues with its all-aluminum microchannel coils.
One common solution is converting the microchannel coil to a copper tube, aluminum fin coil. This type of upgrade has become popular over the years due to its improved performance and reliability.
Microchannel coils have been widely used in the HVAC industry for more than a decade, not only in Lennox systems but also in many other OEM units. While they offer cost savings and lower refrigerant use, they come with their own set of challenges.
The Challenges of Microchannel Coils
These coils can be prone to dirt buildup and require regular maintenance to prevent pressure issues. They also need precise refrigerant charging, which can be tricky due to their low refrigerant capacity. Repairing them is no easy task either — it often involves using two-part epoxy or a torch, both of which can be risky and time-consuming. Plus, aluminum is sensitive to weather conditions, making repairs even more difficult.
Why Upgrade to Copper Tube, Aluminum Fin Coils?
Switching to a high-quality copper tube, aluminum fin coil offers numerous benefits. It enhances system performance, increases reliability, and extends the lifespan of your Lennox unit. Here’s what you gain:
- Greater durability and resistance to damage
- Easier repair and maintenance compared to microchannel coils
- Ability to pump down the system during repairs, saving time and reducing refrigerant loss
- Long-term cost savings by minimizing leaks and repair needs
Completing the Circuit
When replacing a microchannel coil with a copper tube coil, it's important to complete the circuit properly. For example, if your unit has four coils per circuit and one fails, you should replace all four to maintain balance. This is because copper tube coils operate under different refrigerant pressure drops than microchannel coils. Mixing the two can lead to system inefficiencies and operational problems.

Variable valve timing (VVT) solenoid or oil control valve controls the oil flow according to the engine speed and load. VVT solenoid is a vital part of the variable valve timing system.
The Oil Control Valve (OCV) is a a critical part used in every engine that is fitted with variable valve technology (VVT). A single control valve will regulate the supply of oil to a designated VVT hub, to advance or retard the timing by altering the camshaft angle position. Controlled by the ECU, the OCV receives electrical signals, instructing it to adjust the oil flow as required, in accordance to current driving conditions.
