New AC Systems | Same-Day Install | Licensed HVAC Technicians
When it's time to replace your air conditioning system—whether due to age, efficiency concerns, or complete failure—you need experienced HVAC professionals who install systems correctly the first time. Proper sizing, ductwork evaluation, and expert installation are critical to ensuring your new AC system cools efficiently and lasts 15-20 years.
LEX Air Conditioning & Heating has installed thousands of AC systems throughout Coppell since 2004. We serve homeowners in Old Town Coppell, Cottonwood Creek, Riverchase, Hidden Ridge, Austin Waters, and all neighborhoods across ZIP codes 75019 and 75099. Our NATE-certified technicians hold Texas HVAC Contractor License TACLA38788C and follow manufacturer specifications for every installation.
We understand Coppell's unique cooling challenges—from older homes in Riverchase that may need ductwork upgrades to new construction in The Preserve requiring properly sized systems. We perform Manual J load calculations to determine the correct system size for your home, never oversizing or undersizing equipment.

Is it time to replace your air conditioning system?
Air conditioners last 12-15 years on average in Texas heat. If your system is approaching this age, replacement prevents unexpected failures during summer. Newer systems are 30-50% more efficient than models from 2010.
If repair costs exceed $1,000 or you're calling for service multiple times per year, replacement makes financial sense. The "5,000 rule" applies: multiply repair cost by remaining years of life—if it exceeds $5,000, replace.
R-22 refrigerant was phased out in 2020. If your system uses R-22 and develops a leak, refrigerant costs $100-$150 per pound. Replacement with modern R-410A systems is more cost-effective.
Older systems lose efficiency as components wear out. If your summer electric bills have increased 30-50% over the past 5 years, a new high-efficiency system pays for itself through energy savings.
If some rooms stay hot while others are cold, you may have an undersized or oversized system. Proper load calculations and correct sizing solve this problem permanently.
If your AC runs constantly but your home never reaches the set temperature during Texas summers, it's undersized, worn out, or both. Replacement restores proper cooling capacity.
Manual J load calculations ensure correct system size—never oversized or undersized equipment.

AC installation costs $4,500-$9,000 depending on system size, efficiency (SEER rating), and installation complexity. A basic 3-ton 14 SEER system runs $4,500-$6,000, while high-efficiency 18-20 SEER variable-speed systems cost $7,000-$9,000. We provide free in-home estimates with upfront pricing and financing options.
Most AC installations take 6-8 hours for a straightforward replacement. Full-day installations (8-12 hours) are common when ductwork modifications, electrical upgrades, or extensive cleanup are required. We complete most installations in a single day, though complex projects may require 2 days.
Most Coppell homes need 2.5-4 ton systems depending on square footage, insulation, windows, and sun exposure. We perform Manual J load calculations—the industry-standard method for determining correct system size. Oversized systems short-cycle and fail to dehumidify; undersized systems run constantly and never cool properly. Proper sizing is critical for comfort and efficiency.
