AC Repair FAQs

Cool Aid Air Conditioning & Refrigeration offers AC repair, AC installation, heating repair, heating installation, and indoor air quality systems for both residential and commercial clients across the Rio Grande Valley.

A standard AC installation typically takes between 5 to 8 hours from start to finish, including removing the old unit, installing the new system, connecting refrigerant lines, and full testing. Most jobs start in the morning and finish the same day. Commercial rooftop installations take longer, typically a full day.

At least once a year is standard. If you have an older system or run it frequently, especially through a full Rio Grande Valley summer, servicing more often can catch small issues before they become expensive repairs.

Common signs it's time to replace include frequent repairs every season, rising energy bills without increased usage, uneven cooling, unusual noises, and weak airflow. A useful rule of thumb: multiply your system's age by the repair cost. If the total exceeds $5,000, replacement is usually the smarter investment. We'll give you an honest recommendation, repair or replace, before any work begins.

Yes. Most AC emergencies are diagnosed and fixed the same day you call, with customers regularly reporting technicians arriving within an hour. Call us directly for anything urgent.

AC sizing here isn't a guessing game. Most Texas homes need roughly 25 to 30 BTU per square foot, higher than milder climates, because of heat, humidity, ceiling height, and sun exposure. A system that's too small struggles to cool your home; one that's too large cycles on and off too often and wears out faster. We perform a real load calculation before recommending any unit size.

More often than the national average. South Texas dust, humidity, and near year-round AC use clog filters fast, and a neglected filter can push energy use up significantly. For most RGV homes, replace your filter every 30 to 45 days during peak summer, or every 30 days if you have pets or allergy sufferers in the home.

In the RGV, AC repairs typically range from $150 to $2,500 depending on the issue, a capacitor replacement often runs $150–$400, a refrigerant recharge $200–$600, and a compressor replacement $1,200–$2,800. These are general market ranges, not a quote. We provide upfront pricing for your specific issue before any work begins.

Verify their Texas TACL air conditioning and refrigeration contractor license first, it's required by law. Then check Google reviews for a consistent high rating. A trustworthy company gives you a written estimate before work starts and explains your options clearly instead of pushing one option.

The most common causes are a dirty air filter blocking airflow, a failing capacitor preventing the compressor from starting, a refrigerant leak reducing cooling capacity, or a frozen evaporator coil from restricted airflow. In South Texas heat, any one of these escalates fast. Call for same-day diagnostics before a small problem turns into an expensive repair.
