Quick answer
The most common AC problems in Texas are failed capacitors, dirty condenser coils, clogged drain lines, frozen evaporator coils and refrigerant leaks. Before you call, check that the thermostat is set to cool, replace a dirty filter and make sure the breaker is on. If it still is not cooling, a certified technician can diagnose and usually repair it the same day.
AC Repair you can count on
When it is 100 degrees outside, a broken air conditioner is more than an inconvenience. It is a health risk for kids, older family members and pets. Our HVAC technicians are dispatched seven days a week through the summer, with trucks stocked with the parts that fail most often.
Your technician runs a full diagnostic, from electrical components and refrigerant pressures to airflow and drainage, and explains what is wrong in plain terms. You approve a flat price before the repair starts, and if your system is beyond saving, we will tell you honestly.

What affects the cost of ac repair?
AC repair costs depend on the part that failed and the system's refrigerant type. Capacitors, contactors and drain-line clogs are typically quick, affordable fixes. Compressor failures and major refrigerant leaks cost more and may make replacement the better value, especially on older systems.
AC Repair in Dallas–Fort Worth: local insight
Air conditioners in Dallas–Fort Worth run for long stretches from May through September, often in triple-digit heat. That workload wears out capacitors and fan motors faster and makes clean coils and correct refrigerant charge critical. A spring tune-up catches most of these problems before the first heat wave.
