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

I'm Omar Jacobo, owner of Frosty's HVAC. Coppell homes need twice-a-year tune-ups more than most cities we serve, and it comes down to two things: cottonwood and dual-zone systems. Every April through June, cottonwood fluff from Grapevine Lake blankets Coppell — Riverchase, Magnolia Park, and the MacArthur Corridor catch it worst because they face the prevailing lake breeze. That cotton packs condenser coil fins like insulation, choking airflow and forcing compressor temperatures up. A spring AC tune-up in March catches the system before cottonwood season hits, cleans coils, tests capacitor microfarad readings, and flushes condensate drains before algae blooms clog them in the humidity. Fall heating tune-up in September-October catches furnace problems before the first hard freeze — ignitor integrity, flame sensor condition, heat exchanger visual inspection, and CO check at a supply register.

The dual-zone systems in Coppell's two-story homes — Riverchase, Northlake Woodlands, Copperstone, Alexander Court — mean two separate air handlers, two condensers, and double the maintenance checkpoints. Our Coppell tune-up covers both zones: 21 inspection points per system including evaporator and condenser coil cleaning, refrigerant level check with electronic 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, blower wheel and motor amp draw, electrical connection torque check, and zoning damper actuator verification. I write up the inspection report in front of you and explain every finding. Basic tune-up is $150 per system ($127.50 for Frosty Club members).

For Coppell homes that haven't been serviced in 3+ years — common on the older ranch homes in Old Coppell that change hands or on Northlake Woodlands homes where the previous owner skipped maintenance — the super tune-up ($1,300 per system, $1,105 for members) is the right call. I pull the evaporator coil and blower assembly, deep-clean both, leak-check and recharge refrigerant to manufacturer spec per EPA 608 rules, and restore the system to factory performance. On a neglected 15-20 year old Coppell system, this typically recovers 15-25% of lost efficiency, which translates directly to lower Oncor bills.
