When necessary, we modify or replace ductwork to ensure proper airflow throughout your home. Many Richardson homes have ductwork in unconditioned attics, where sealed ducts save significant energy.

Learn MoreNot sure if you need AC installation or just repair? Watch for these indicators that replacement makes more sense than another repair.
AC systems last 15-20 years with proper maintenance, but efficiency declines after 12 years. If your Richardson home has an older system facing expensive repairs, replacement often delivers better long-term value and significantly lower energy bills.
Increasing electricity costs even with consistent usage patterns indicate declining efficiency. Modern high-SEER systems can cut your cooling costs 30-50% compared to older units, paying for themselves over time through reduced utility bills.
If you're calling for AC repair multiple times per season, you're throwing good money after bad. When repair costs exceed 50% of replacement value, new installation makes financial sense. Plus, you get warranty coverage and peace of mind.
Rooms at different temperatures usually indicate an improperly sized system or failing equipment. New installation with proper load calculations ensures even comfort throughout your entire Richardson home, from Canyon Creek to Spring Valley neighborhoods.
If your system uses R-22 (Freon), replacement parts and refrigerant are increasingly expensive and difficult to source. Modern systems use R-410A refrigerant and deliver superior efficiency. Upgrading now avoids future supply issues and high R-22 costs.
Older systems struggle to control humidity and filter air effectively. New AC installation includes modern filtration options and better dehumidification, improving your indoor air quality and protecting your Richardson home from mold and allergens.
"LEX installed a new 17-SEER system in our Canyon Creek home last June, right before the heat hit. Their team arrived on time, completed everything in one day, and cleaned up perfectly. Our electric bill dropped by almost $100 per month compared to the old unit. Best investment we've made in this house."

Complete AC installation for Richardson homes typically ranges from $5,500 to $12,000, depending on system size, SEER rating, brand selection, and any necessary ductwork modifications. We provide free in-home estimates with upfront pricing—no surprises. We also offer flexible financing options to fit your budget.
Proper sizing requires a detailed Manual J load calculation that accounts for your home's square footage, insulation levels, window placement, orientation, and local climate. Most Richardson homes need 2.5 to 5-ton systems. Oversized systems cycle too frequently and don't dehumidify properly; undersized systems run constantly. We perform accurate load calculations for every installation.
For Richardson's hot climate, we recommend minimum 16 SEER for excellent efficiency and comfort. Higher SEER systems (17-20+) cost more upfront but deliver greater energy savings over the system's lifetime. With Texas electricity rates, high-efficiency systems typically pay for themselves within 7-10 years through reduced cooling costs.
