AC TUNE-UP & MAINTENANCE INLEWISVILLE, TX — FROSTY'S HVAC

Lewisville earns twice-yearly tune-ups more than most Denton County cities because Lewisville Lake humidity loads evaporator coils and condensate drains harder than inland neighborhoods. Old Town Lewisville 1960s-1970s ranches with original flex ductwork already have restricted airflow — add biofilm from lake-corridor moisture and those coils freeze during the first sustained 100°F+ week. Valley Vista (established 1986) follows the same pattern. Castle Hills homes are newer but their 3,000-5,000 sqft floor plans run larger systems that move more air through more ductwork, producing heavier condensate loads that need proactive drain management. Vista Ridge and the Highland Village border share this moisture profile.

Our Lewisville basic tune-up covers 21 checkpoints: evaporator and condenser coil cleaning, refrigerant level check against manufacturer spec with leak detection if low (we never top off hermetic systems — if it's low, there's a leak), capacitor microfarad test, contactor inspection, condensate drain flush and float switch test, thermostat calibration including dehumidification mode settings, blower wheel and motor amp draw, electrical connection torque check, and full CO test at a supply register on gas systems fueled by Atmos Energy. Basic tune-up is $150 flat ($127.50 for Frosty Club Basic members).

For Lewisville homes that haven't been serviced in 3+ years — common after a home changes hands, especially in Valley Vista and Old Town where turnover happens — the super tune-up ($1,300, $1,105 for members) is the right call. We pull the evaporator coil and blower assembly, deep-clean both, leak-check and recharge refrigerant to manufacturer spec per EPA 608 rules, and restore factory performance. No gas-and-go. On a neglected 8-12 year old Lewisville system this typically recovers 15-25% of lost efficiency. I'm Omar Jacobo, EPA 608 Universal #2396328; Mariafernanda holds TACLA126718E.
