Wade & Sons | Expert HVAC Services in San Antonio, TX

In San Antonio, with our significant dust and allergen levels, we recommend checking your filter monthly and changing it every 1-3 months. A clogged filter restricts airflow, forcing your system to work harder, which can lead to higher bills and even cause your evaporator coil to freeze. During peak summer or if you have pets, more frequent changes are a good idea. We can recommend the best filter type for your home during a maintenance visit.

A frozen evaporator coil is a common issue here, often caused by restricted airflow from a dirty filter, low refrigerant levels, or a failing blower motor. The first step is to turn the system off to let it thaw. Our technicians will then perform a full diagnostic to pinpoint the exact cause—whether it's a simple filter replacement, a refrigerant leak repair, or a component fix. Addressing the root cause prevents recurring freeze-ups and protects your compressor from damage.

Proactive, bi-annual maintenance is key. Our tune-up includes cleaning the evaporator and condenser coils, checking refrigerant levels, calibrating your thermostat, inspecting electrical connections, and ensuring the blower motor is functioning properly. This service specifically targets the dust buildup and system strain that lead to the clogged filters and freeze-ups common in our area. It improves efficiency, extends your system's life, and helps avoid emergency repairs during our hottest months.
