Comprehensive air conditioning repair solutions for every Richardson neighborhood
Low refrigerant is one of the most common AC problems in Richardson homes. Our technicians use advanced leak detection equipment to locate even the smallest leaks in your refrigerant lines, repair them properly, and recharge your system to manufacturer specifications. We handle both R-410A and older R-22 systems.
Learn MoreThe compressor is your AC's heart—when it fails, so does cooling. Richardson's extreme heat puts extra stress on compressors. We diagnose compressor issues quickly, determine if repair or replacement makes economic sense, and handle the job with precision. Many repairs include warranty coverage from manufacturers.
Learn MoreIce on your evaporator coil? This serious problem stems from airflow restrictions, refrigerant issues, or failing components. Our technicians safely thaw frozen coils, identify the underlying cause—whether it's a dirty filter, blocked return, or refrigerant leak—and fix it to prevent recurrence.
Learn MoreCapacitors, contactors, relays, and control boards fail frequently in Texas heat. Our TECL23192-licensed electricians diagnose electrical failures accurately, replace failed components with quality parts, and ensure your AC's electrical system operates safely and reliably for years to come.
Learn MoreWhen your blower motor fails, your AC produces little or no airflow. We repair and replace blower motors, fan blades, and associated components. Our technicians also clean blower assemblies clogged with dust—a common issue in Richardson homes—restoring proper airflow and system efficiency.
Learn MoreSometimes the problem isn't your AC—it's the thermostat. We diagnose thermostat malfunctions, wiring issues, and calibration problems. Whether you have an old mechanical thermostat or a modern smart system like Nest or Ecobee, we'll get it communicating properly with your air conditioner.
Learn MoreDon't wait until your AC completely fails on the hottest day of summer. Watch for these warning signs that indicate your Richardson air conditioner needs professional repair:
If your AC runs but produces warm air or struggles to cool your Richardson home, you likely have a refrigerant leak, compressor failure, or airflow restriction. This requires immediate professional diagnosis to prevent complete system failure.
Unusual sounds signal mechanical problems. Grinding indicates bearing failure, squealing suggests belt issues, and banging points to loose components. These problems worsen rapidly—call LEX before minor issues become expensive repairs.
Ice on your AC coils indicates serious problems: refrigerant leaks, airflow restrictions, or failing components. Never operate an AC with ice buildup—it causes compressor damage. Our technicians diagnose the root cause and fix it properly.
Condensate drain clogs cause water damage to Richardson ceilings and walls. If you see water pooling around your indoor unit or dripping from vents, you need immediate repair. We clear drain lines and prevent future water damage.
Sudden spikes in your electric bill often indicate AC inefficiency from failing components, refrigerant leaks, or dirty coils. Our diagnostic process identifies efficiency problems and restores your system to optimal performance, lowering your cooling costs.
If your AC short-cycles (turns on and off rapidly) or won't stay running, you're facing thermostat issues, electrical problems, or refrigerant concerns. Short-cycling damages your compressor and drives up energy costs—get it fixed fast.
"Our AC died at 3 PM on a 105-degree day in Canyon Creek. LEX had a technician here in 20 minutes! He diagnosed a bad capacitor, had the part on his truck, and we were back to cool air in 45 minutes. Honest pricing, professional service, and they genuinely cared about getting our family comfortable again. We're LEX customers for life."
Richardson's approximately 120,000 residents live in one of North Texas's most diverse communities, with housing stock ranging from charming 1960s-era ranches to modern construction near the UT Dallas campus. This variety means Richardson homeowners face different AC challenges depending on their neighborhood and home age.
Older homes in established areas like Canyon Creek and Northrich often feature aging AC systems with outdated components, inadequate insulation, and ductwork that hasn't been serviced in decades. These systems work harder in Texas heat, leading to frequent breakdowns. Our technicians have extensive experience with older equipment and can often extend system life with targeted repairs—or provide honest guidance when replacement makes better financial sense.
Newer Richardson homes near Spring Valley and the University area typically have modern, high-efficiency AC systems. However, these sophisticated units require specialized diagnostic tools and training that many HVAC companies lack. LEX technicians receive ongoing manufacturer training on the latest AC technology, ensuring we can properly diagnose and repair even the newest systems with complex variable-speed compressors and advanced controls.
Richardson's proximity to major employment centers means residents can't afford extended AC downtime. That's why we maintain a 15-20 minute response time from our Plano headquarters and stock our trucks with hundreds of common AC parts. Most Richardson repairs are completed in a single visit, getting your family back to comfort fast. We also offer Cool Club maintenance memberships that prevent breakdowns through proactive care—a smart investment for Richardson homeowners who want reliable cooling year-round.

Frozen AC coils result from restricted airflow (dirty filters, blocked returns, failed blower motor), low refrigerant from leaks, or outdoor temperatures below 60°F during operation.
