AC repair costs vary depending on the issue. Minor repairs like capacitor or contactor replacement typically range from $150–$400, while more complex repairs involving compressors or refrigerant leaks can cost $500–$1,500 or more. At LEX Air, we provide upfront pricing before starting any work, so you’ll never be surprised by your bill.
We offer same-day service for most AC repair calls in the Carrollton and Dallas areas. For true emergencies during extreme heat, we prioritize getting a technician to your home as quickly as possible — often within a few hours.
As a general rule, if your AC is more than 10–15 years old and the repair costs exceed 50% of the price of a new system, replacement is usually the better investment. Older systems also use R-22 refrigerant (Freon), which is no longer manufactured and increasingly expensive. Our technicians can help you weigh the costs and benefits of repair vs. replacement for your specific situation.
Common causes include low refrigerant levels, a dirty air filter restricting airflow, a frozen evaporator coil, a malfunctioning compressor, or a faulty thermostat. Sometimes the outdoor condenser unit is blocked by debris or vegetation. We recommend checking your filter first — if that’s not the issue, call us for a professional diagnosis.
Yes! We understand that AC failures often happen at the worst possible times. LEX Air provides emergency repair services throughout the Dallas-Fort Worth area. Call us at (469) 240-2628, and we’ll work to get your cooling restored as quickly as possible.
We recommend having your air conditioning system professionally maintained at least once a year, ideally in the spring before the summer cooling season begins. Regular maintenance improves efficiency, extends equipment life, and helps prevent unexpected breakdowns. Our Cool Club Maintenance Plan makes it easy to stay on schedule.
Our technicians are trained to repair all major AC brands, including Trane, Carrier, Lennox, Rheem, Goodman, York, American Standard, Bryant, Amana, Daikin, and more. As a Trane Comfort Specialist, we have particular expertise with Trane systems, but we’re equipped to handle whatever equipment is in your home.
