When it comes to A/C problems, one of the most common parts to fail is the evaporator coil. For leaking in newer air conditioning units, you may have a small leak in the welding or loose joints, due to poor installation. However, if you are consistently adding coolant to an older air conditioning unit, you may have a leak caused by corrosion in the copper tubing, and you may need A/C coil repair.
What Causes The Need For A/C Coil Repair?
Many homeowners believe that particularly hot summers, or heavy usage of the air conditioner can cause your unit to become low on coolant. However, in air conditioners, the only component that should be burning off, is energy. That said, if your coolant is lower than the recommended levels, your unit has a leak.
Many homeowners, particularly those with newer, high efficiency units, can be frustrated by leaky evaporator coils, since they appear to fail every few years. With older units, the coils seem to last much longer, though they ultimately fail as well.
The leaks are caused by the accumulation of formic acid inside the evaporator coil. This formic acid develops after formaldehyde, from furniture, finishes, and cleaning supplies, circulates through the air in your home, and through your air conditioning unit. The formic acid eventually eats through the tubing and causes costly leaks, leading to necessary A/C coil repair or replacement. In newer systems, the copper tubing is much thinner, which is part of how they cool so efficiently. Unfortunately this is the same reason they develop leaks sooner.
How Can You Prevent A/C Coil Leaks?
To avoid A/C coil leaks, there are a few steps you can take. Open windows in your home more frequently, to allow circulation of outside air, which can help dilute some of your household toxins. Additionally, have your unit maintained yearly, so that our technicians can flush the A/C coil with a neutralizing solution, to significantly extend its lifespan.
