We Repair Boiler’s Crashes Instantly With Precision
Done Right, Every Time — That’s the Sigma Air Promise
Boiler repair in San Antonio requires precision, experience, and accountability. When problems are ignored, comfort disappears. At Sigma Air Heating & Cooling, we solve the root cause, not just the symptoms, so your system runs reliably all season long.
Low Water Pressure Solutions

When your pilot won’t stay lit, we inspect thermocouples, clear blockages, and restore reliable ignition—so your heat stays on.
Noise Elimination (Kettling)
Banging, whistling, or gurgling? We flush sludge, remove limescale buildup, and bleed trapped air to quiet your system and improve performance.
Total System Failures
No heat or hot water? We troubleshoot failed pumps, thermostats, and airlocks fast—restoring warmth when you need it most.
