Southern Air: Licensed HVAC Services Serving Mission 78574

In our humid Mission climate, a frozen coil is often caused by restricted airflow or low refrigerant. Dirty air filters, blocked return vents, or a failing blower motor can reduce airflow, causing the coil to get too cold and freeze. Low refrigerant from a leak has the same effect. Our technicians will diagnose the root cause, whether it's a simple filter change or a refrigerant leak repair, to get your system running safely and efficiently again.

Clogged drains are very common here due to algae and mold growth in our moist air. The best prevention is a professional maintenance visit at least once a year. During this service, we'll vacuum out the drain line and treat it with an algae-inhibiting tablet. You can also help by changing your air filter regularly, as a dirty filter can cause more moisture to bypass the coil and enter the drain line, accelerating clogs.

Watch for reduced cooling, unusual noises, higher-than-normal energy bills, ice on refrigerant lines or the indoor unit, and water pooling around your indoor air handler. These are all signs of issues like dirty coils, low refrigerant, or clogged drains that are common in our area. Catching them early with a tune-up from Southern Air can prevent a minor issue from turning into a costly, sweltering breakdown during our hottest months.
