If your allergies get worse indoors or the air just doesn't feel right, you're probably not wrong. Poor air quality is common in older homes and neglected HVAC systems. Cowboy's AC offers comprehensive solutions to clear the air — and free airflow testing to get started.
You might not think about your ducts — they're hidden, after all — but they're one of the biggest reasons a home feels unevenly heated or cooled. Leaky ducts drain your wallet and your comfort. If your system is over 15 years old, a duct inspection may reveal more savings than you'd expect.

It could be airflow, a dirty filter, low refrigerant, the outdoor unit, frozen coils, a thermostat issue, or a failing component. Because San Antonio heat puts heavy demand on cooling systems, it's best to schedule service before the problem gets worse — we'll identify the cause and recommend the right repair.
A healthy system cools about 15–20° below the outdoor temperature. In peak San Antonio heat it may run longer, but it should still produce cold air and pull humidity. If it feels weak or warm, have it checked.
Yes — holidays, weekends, the middle of the night. If the weather doesn't wait, neither do we. Call (210) 495-7771 any time.
Yes — we're an authorized Trane dealer and Comfort Specialist, and we service every major brand, so you're never locked in.
Your system should have a brief delay before restarting after it shuts off — this protects the compressor and prevents unnecessary wear. Most modern thermostats manage it automatically. Frequent on/off cycling can signal short cycling or another issue worth inspecting.
Poor airflow is one of the most common — it makes rooms feel unevenly heated and lowers efficiency. If your furnace isn't heating properly, cycles too often, or makes unusual noises, we can get it working safely and reliably.
