S-Tex: Top-Rated HVAC Repair Serving Mission 78573

Uneven cooling, especially in multi-level homes, is very common in our Mission heat. It's often due to an undersized unit, ductwork issues, or poor airflow balancing. S-Tex performs a detailed assessment of your entire system—checking duct sizing, insulation, and thermostat placement—to diagnose the exact cause. We then provide solutions like duct sealing, installing zoning systems, or adjusting airflow dampers to create balanced, consistent comfort throughout your entire home.

Yes, a refrigerant leak is a likely culprit, especially as systems age in our demanding South Texas climate. This not only reduces cooling power but also makes your system work harder, increasing energy bills. S-Tex technicians are EPA-certified to safely locate and repair leaks. We never just 'top off' refrigerant; we find the source of the leak, fix it properly, and then recharge the system to its manufacturer specifications, restoring efficiency and protecting your compressor from damage.

Preventative maintenance is key in our climate. Our recommended bi-annual service includes cleaning coils and condensate drains (vital for humidity control), checking refrigerant levels and pressure to catch leaks early, inspecting and tightening all electrical connections, and calibrating your thermostat. This proactive care helps prevent the uneven cooling and loss of capacity that many Mission homeowners experience, extending your system's life and maintaining its efficiency through the hottest months.
