Dallas summers are brutal, with temperatures regularly exceeding 100°F. Your AC system isn't just a luxury—it's essential for your family's comfort and safety. Whether you're replacing an aging system or installing AC in a new home, LEX Air Conditioning provides expert installation throughout Dallas, from Downtown to Oak Lawn, Uptown to Lake Highlands.
We install all major brands including Trane, Carrier, Lennox, Goodman, and more. Our expert load calculations ensure your new system is properly sized for Dallas's extreme climate, maximizing efficiency and longevity.
Dallas homes vary from historic bungalows to modern estates. We perform detailed Manual J load calculations to ensure your AC system is perfectly sized—not too small (constant running) or too large (short cycling). Proper sizing means better efficiency, lower bills, and longer system life.
Dallas's scorching summers mean your AC runs 24/7 from June through September. High-efficiency systems (16-20 SEER2) can cut your cooling costs by 30-50% compared to older units. We'll show you payback periods and help you choose the right efficiency level for your home and budget.
All major AC brands include 10-year parts warranties when professionally installed. Our installation workmanship is guaranteed, and we handle all warranty claims directly—no runaround, no hassle. We stand behind every system we install.

Our licensed technicians install your system with precision. We protect your home, install the new equipment, connect ductwork, wire the thermostat, test refrigerant levels, and verify proper airflow. Most installations finish in 6-10 hours.
Before we leave, we test your system extensively—cooling performance, thermostat operation, air distribution, and sound levels. We'll train you on your new system and thermostat so you get maximum comfort and efficiency.

Dallas homes typically need 1 ton of cooling per 400-600 square feet, but this varies based on insulation, windows, ceiling height, and sun exposure. A 2,000 sq ft Dallas home usually needs a 3.5-4 ton system. We perform Manual J load calculations to determine the exact size for your home.
In Dallas's extreme climate, high-efficiency systems (16-20 SEER2) often pay for themselves within 5-8 years through energy savings. If you plan to stay in your home long-term and your current system is over 10 years old, upgrading to high-efficiency makes financial sense. We'll calculate your specific payback period.
