Licensed HVAC Services in Oklahoma City, OK 73150 - United Mechanical

This is a common issue during our intense summers, often caused by a frozen evaporator coil, a refrigerant leak, or a failing compressor. The unit works harder in extreme heat, exposing these weaknesses. Our technicians can quickly diagnose the root cause—whether it's a simple airflow restriction or a more complex mechanical failure—and perform the necessary repair to get your cool air flowing again.

A frozen evaporator coil is usually a symptom of restricted airflow (from a dirty filter or blocked vents) or low refrigerant levels. When this happens, your system can't absorb heat properly. We'll first safely thaw the coil, then pinpoint the exact cause. The fix may involve cleaning, replacing the air filter, sealing duct leaks, or recharging refrigerant to prevent it from happening again.

A professional preventative maintenance tune-up is the best defense. Before the heat hits, we perform a comprehensive check, including cleaning coils, checking refrigerant levels, inspecting electrical components, and ensuring the entire system is operating efficiently. This proactive service helps prevent the most common mid-summer breakdowns, improves cooling performance, and can lower your energy bills.
