Sustr's Air Conditioning Contractors - Schulenburg's Certified HVAC Repair

First, check your thermostat settings and circuit breaker to rule out simple issues. If those are fine, call us immediately. A sudden failure in extreme heat often points to a compressor overload, refrigerant leak, or electrical fault. We prioritize these emergency calls to quickly diagnose the problem, often same-day, and get your home cool and safe again.

Signs include the system blowing cool air when set to heat (or warm air when set to cool), or failing to switch modes entirely. Schulenburg's climate means your heat pump cycles between heating and cooling frequently throughout the year. This constant use puts extra wear on the reversing valve. Our technicians are skilled at testing valve function and performing precise replacements to restore your system's full efficiency for both seasons.

Proactive maintenance is key. We recommend a professional tune-up in the spring. Our service includes cleaning coils, checking refrigerant levels, tightening electrical connections, and inspecting components prone to fail under strain—like capacitors and contactors. This Schulenburg-focused check-up can identify small issues before they cause a major breakdown when you need your system the most.
