What we check during a Keller AC tune-up
We measure refrigerant levels and look for leaks because cooling season runs long here, and even small refrigerant losses pile up over a five-month run. We clean and look over the condenser coils on the outdoor unit, where cottonwood fluff in late spring, mowing dust kicked up across yards in Hidden Lakes and Marshall Ridge, and grit blowing in off Highway 377 construction zones choke airflow and force the compressor to work harder. We check the evaporator coil for ice or grime that cuts heat transfer and leaves your home warmer than the thermostat setting.
We tighten electrical connections and test voltage across all parts because the swing between July highs above 100 and January lows in the 20s makes metal expand and contract, loosening connections over months of running. We test capacitors with a meter because the brutal sun load on Keller condensers breaks them down faster than people expect, and a bad capacitor is the single most common reason for AC breakdowns we see across northeast Tarrant County. We calibrate the thermostat so the reading matches reality.
We flush the condensate drain because Keller's spring humidity drives heavy condensate volume and the local hard water leaves mineral scale that clogs the line. We check and replace the filter if needed. We measure blower motor amps to spot motors pulling too much power, a sign they are about to fail. And we look at accessible ductwork for leaks, splits, and damage, especially in unconditioned attics where flex duct takes a beating from 140-degree summer heat.

Best time to book AC maintenance in Keller
Sweet spot: March or April. The system has been mostly idle through the cool months. Pollen, cottonwood fluff, and dust have settled on parts. Capacitors have not been pushed by heat yet, so we can spot a weak one before it gives out on the first 95-degree day in late May.
By May our calendar tightens up. Keller homeowners who call in March get same-week slots. By late May you wait two weeks. By July and August, when systems break down across the city during 105-degree stretches, we run emergency calls all day and tune-ups slip to September.
Spring service catches 80% of the problems that turn into emergency AC calls in July and August. A weak capacitor caught in March is a $20 part and 10 minutes of labor. That same capacitor failing during a heat wave means a dead AC on the hottest day of the year and an after-hours call. Get ahead of it.
The $100 you spend in March saves $500 in August.
Book your tune-up now before the spring slots fill up. Same-day and next-day openings open through April.

The dollars and cents of regular tune-ups
Annual tune-up: $89 to $149. Average peak-summer emergency repair: $350 to $600. New system when neglect kills the compressor: $6,000 to $12,000. The math makes the case.
Maintained systems run 12 to 18 years in this climate. Neglected ones run 7 to 10. That is 3 to 8 more years of life out of a $100-a-year spend. A single refrigerant leak caught during a tune-up saves $200 to $400 in wasted cooling output and prevents the compressor damage that turns a $300 fix into a $2,000 repair. If your system is getting on in years and you are weighing maintenance against a new install, call us for an honest read.
Homeowners who call us in March do not call us in August. Their systems just run. Call (817) 945-6320 to get on the schedule.
