Dallas heat puts unique stress on AC systems. Here are the problems we repair most often:
Your AC runs but doesn't cool your Dallas home. Common causes: refrigerant leaks, dirty coils, failed compressors, or clogged filters. We diagnose the root cause and restore cooling fast.
When your AC won't start during Dallas heat, it's an emergency. We check thermostat issues, breaker trips, capacitor failures, and control board problems to get you cooling again.
Your AC turns on and off constantly, wasting energy. Causes include oversized units, dirty filters, refrigerant issues, or thermostat problems. We diagnose and fix cycling issues.
Water pooling around your indoor or outdoor unit signals drain line clogs, frozen coils, or condensate pump failures. We clear blockages and prevent water damage.
Grinding, squealing, or banging sounds mean mechanical problems. We repair failing compressors, worn bearings, loose parts, and motor issues before they cause total failure.
Sudden spikes in summer cooling costs indicate efficiency problems. We identify dirty coils, refrigerant leaks, ductwork issues, and aging components robbing your efficiency.

Yes! LEX provides 24/7 emergency AC repair throughout Dallas. When your AC fails during a 100° summer day or sweltering night, we respond fast. Emergency service does cost more than regular business hours (typically 1.5x to 2x our standard rates), but we always provide upfront pricing. We understand that a broken AC in Dallas heat isn't just uncomfortable—it's dangerous, especially for elderly residents, young children, and those with health conditions.
LEX services all major AC brands throughout Dallas including Trane, Carrier, Lennox, Rheem, Goodman, York, American Standard, Bryant, Amana, Daikin, Coleman, Heil, Payne, Armstrong, and more. Our technicians receive ongoing training on all major brands and carry diagnostic equipment compatible with every system. Whether you have a brand-new high-efficiency system or an older unit, we have the expertise and parts to repair it.
The decision depends on your AC's age, repair cost, and efficiency. General rule: if your AC is under 10 years old and repair costs less than 30% of replacement cost, repair makes sense. If it's 15+ years old, uses R-22 refrigerant (discontinued), experiences frequent breakdowns, and repair costs exceed 50% of replacement, a new energy-efficient system often saves money long-term. Our technicians provide honest advice—we never pressure Dallas customers into unnecessary replacements. We'll explain your options and help you decide.
Most AC repairs in Dallas are completed in 1-3 hours during a single service visit. Simple repairs like capacitor or contactor replacement take 30-60 minutes. Standard repairs like refrigerant recharge or coil cleaning take 1-2 hours. Complex repairs like compressor replacement take 3-5 hours. Our technicians carry fully-stocked service vehicles with common AC parts, allowing us to complete most Dallas AC repairs on the first visit without return trips for parts.
