Learn MoreRecognize these warning signs that indicate it's time for a new AC system rather than another repair.
AC units older than 12-15 years become increasingly inefficient and costly to repair. Modern systems offer significantly better efficiency, potentially cutting cooling costs by 30-40% compared to older units.
If repair costs exceed 50% of a new system's cost, or you're calling for service multiple times per cooling season, replacement becomes the more economical choice for Richardson homeowners.
Steadily increasing cooling costs despite similar usage patterns indicate declining efficiency. A new high-efficiency AC system can dramatically reduce your Richardson home's summer energy expenses.
Hot and cold spots or rooms that never reach comfortable temperatures may indicate an undersized or failing system. Proper load calculations and new AC installation solve these comfort issues permanently.
Older AC units using R-22 refrigerant (Freon) are obsolete, and refrigerant is extremely expensive. When major repairs require refrigerant replacement, installing a new system with modern R-410A refrigerant makes financial sense.
Grinding, squealing, or rattling sounds from an aging AC unit often signal major component failure. While some repairs are possible, persistent noise issues in older systems indicate it's time for replacement.

Our Plano-based team reaches Richardson homes in 20-30 minutes for consultations and estimates. Most AC installations are completed in one day, with same-day installation available for many system replacements. We schedule installations at your convenience and work efficiently to minimize disruption to your home.
AC installation costs in Richardson typically range from $4,500 to $9,500 depending on system size, efficiency rating (SEER), brand selection, and installation complexity. We provide free in-home consultations with upfront pricing—you'll know the exact cost before we begin work. Financing options are available to make your new AC system affordable.
Proper AC sizing requires professional load calculations that account for your home's square footage, insulation, window placement, ceiling height, and other factors. Richardson homes typically need 2-5 ton systems depending on size and construction. Our technicians perform detailed load calculations to ensure your new AC is properly sized—neither undersized (causing inadequate cooling) nor oversized (causing short-cycling and humidity issues).
LEX installs premium AC brands including Carrier, Trane, Lennox, American Standard, Rheem, and Goodman. We help Richardson homeowners select the right brand and model based on budget, efficiency goals, and home requirements. All systems we install come with manufacturer warranties and our satisfaction guarantee.
Most residential AC installations in Richardson are completed in 6-10 hours (one full day). Simple system replacements where existing ductwork is in good condition may be completed faster, while installations requiring ductwork modifications, electrical upgrades, or zoning system installations may extend to 1-2 days. We provide a clear timeline during your consultation.
Not necessarily, but it's often recommended. During your consultation, we inspect existing ductwork for leaks, damage, inadequate sizing, or poor insulation. Many Richardson homes built before 2000 have ductwork issues that reduce efficiency by 20-30%. If your ducts are in poor condition, upgrading them alongside your new AC installation maximizes system efficiency and home comfort.
New AC systems include manufacturer warranties covering parts (typically 5-10 years) and compressor (up to 10 years when registered). LEX also provides a 1-year labor warranty on all installation work. Extended warranty options are available for additional peace of mind. We register your warranty with the manufacturer and provide all documentation.
