Expert air conditioning replacement for homes and businesses. Upgrade to a modern, energy-efficient system and start saving on utility bills today.
When your air conditioning system reaches the end of its lifespan, constant repairs become more expensive than replacement. A new, energy-efficient AC system can cut your cooling costs by 20-40%, improve indoor comfort, and eliminate the stress of unexpected breakdowns during Texas summers.
LEX Air Conditioning has been installing and replacing AC systems across the Dallas-Fort Worth area since 2004. Our NATE-certified technicians help homeowners and businesses choose the right system size and efficiency rating for their space, then complete expert installation that ensures optimal performance and longevity. We work with all major brands including Trane, Carrier, Lennox, and Rheem.
From system selection to final installation, we handle every aspect of your AC replacement project.

Don't ignore these warning signs — early replacement can save you money and prevent summer emergencies.
Most AC units last 10-15 years in Texas. If yours is in this range and requiring repairs, replacement is typically more cost-effective than continued repairs.
Significant increases in cooling costs indicate your system is losing efficiency. Older units can use 30-50% more energy than modern replacements.
If you're calling for AC repairs multiple times per season, you're spending more on band-aid fixes than a new system would cost.
Systems using R-22 (Freon) refrigerant are obsolete. R-22 is no longer produced, making repairs increasingly expensive and difficult.
Hot spots, cold spots, or rooms that never reach the right temperature indicate your system can no longer handle your home's cooling load effectively.
Grinding, squealing, or banging sounds from your AC unit, or musty odors when the system runs, signal serious internal problems that often aren't worth repairing.

We provide AC replacement throughout the Dallas-Fort Worth metroplex.
We offer complete heating and cooling solutions for your home.
Most AC system replacements are completed in one day (6-10 hours). Complex installations or larger homes may take up to two days. We'll give you an accurate timeline during your free consultation.
If your AC is over 10 years old and the repair cost exceeds $1,500-2,000, replacement is usually more cost-effective. Use the 5000 rule: multiply the repair cost by the unit's age. If the result exceeds 5,000, choose replacement. Also consider if your system uses obsolete R-22 refrigerant or if you're experiencing frequent breakdowns.
In Texas, we recommend at minimum a 16 SEER system for balanced efficiency and cost. If you want maximum energy savings and plan to stay in your home long-term, 18-20 SEER systems offer the best long-term value despite higher upfront costs. We'll calculate your specific savings during our consultation.
Yes, we offer flexible financing options for qualified customers. We work with several lending partners to provide competitive rates and terms that fit your budget. Many customers choose financing to upgrade to a more efficient system without a large upfront payment.
Proper sizing requires a Manual J load calculation that considers your home's square footage, insulation levels, window quality, orientation, and other factors. A system that's too small won't cool effectively; one that's too large will cycle too frequently and waste energy. We perform precise load calculations as part of every estimate.
New AC systems typically include a 10-year manufacturer warranty on parts and a 5-year compressor warranty. We also offer extended warranty options and maintenance plans to protect your investment. All our installation labor is backed by our satisfaction guarantee.
