Professional HVAC Repair in Schertz, TX 78154 - GVEC Air Conditioning & Heating

In our Schertz climate, an improperly sized system is a common issue that leads to discomfort and high energy bills. An oversized AC will short-cycle, failing to dehumidify your home properly, while an undersized unit struggles during peak summer heat. Our technicians perform detailed Manual J load calculations, specific to your home's construction, insulation, and local weather patterns, to ensure your new system is sized for optimal efficiency, comfort, and longevity.

Our maintenance plan is designed to keep your system running reliably and efficiently. It includes a comprehensive tune-up with cleaning, inspection of electrical components and refrigerant levels, lubrication of moving parts, and a safety check of your heat exchanger. For heat pump owners, we pay special attention to the reversing valve and defrost cycle. This proactive care helps prevent unexpected breakdowns, maintains manufacturer warranties, and can improve your system's overall energy efficiency.

The reversing valve switches your heat pump between heating and cooling modes. If it's stuck or failing, you might notice the system only blows cool air in winter or warm air in summer, or it may struggle to reach the set temperature. As a local expert, we know these valves can be stressed by our temperature swings. Our technicians are trained to diagnose this specific issue and can often repair the valve or recommend the best course of action to restore your home's comfort.
