What Homeowners in Mountainside Ask Us

Why does my AC coil keep freezing up?
If you see ice on the indoor coil or refrigerant line, the most common reasons are poor airflow or a refrigerant problem. Running the system like that can lead to water leaks once the ice melts. In Union County, drain line clogs and related airflow problems are frequent causes of indoor water leaks.

What causes a clogged or leaking condensate drain line?
Indoor HVAC leaks are often drainage problems rather than refrigerant leaks. The usual culprits are a clogged drain, failed pump, rusted pan, or a frozen coil caused by airflow or refrigerant issues. In Union County, drain line clogs and related airflow problems are frequent causes of indoor water leaks.
