AC Repair FAQs | Cool Aid Air Conditioning & Refrigeration

---

Cool Aid Air Conditioning & Refrigeration offers a wide range of HVAC services, including installation, maintenance, and repair of heating, ventilation, and air conditioning systems for both residential and commercial clients.

A standard AC installation typically takes between 5 to 8 hours from start to finish. That includes removing your old unit, installing the new system, connecting refrigerant lines, and full testing. In most cases your contractor will arrive in the morning and have your new system running by afternoon or early evening. Commercial rooftop installations take longer — typically a full day. Cool Aid Air Conditioning works efficiently so your home or business is never without cooling longer than necessary.

To keep your HVAC system running efficiently, it's important to have it serviced at least once a year. However, if you have an older system or if you use it frequently, you may want to have it serviced more often.

Common signs your system needs replacing include frequent repairs every season, rising energy bills without increased usage, uneven cooling throughout your home, unusual noises like grinding or rattling, and weak airflow from vents. In the RGV, extreme heat accelerates wear significantly. A useful rule of thumb is the "5,000 Rule" — multiply your system's age by the repair cost. If the total exceeds $5,000, replacement is usually the smarter investment. Cool Aid Air Conditioning will always give you an honest recommendation — repair or replace — before any work begins.

AC sizing in South Texas is not a guessing game. Most Texas homes need about 25 to 30 BTU per square foot — significantly higher than milder climates — due to heat, humidity, ceiling height, and sun exposure. A system that is too small will struggle to cool your home, while one that is too large will cycle on and off too frequently, wasting energy and wearing out faster. Cool Aid Air Conditioning performs proper load calculations before recommending any unit size — never a guesswork estimate.

In the RGV, filters need changing more frequently than the national average. South Texas dust, humidity, and near year-round AC use clog filters fast. Neglected systems consume up to 30% more energy — directly inflating your monthly utility bills. For most RGV homes, replace your filter every 30 to 45 days during peak summer months. Homes with pets or allergy sufferers should change filters every 30 days. A clean filter is the single cheapest thing you can do to protect your AC system and lower your CPS Energy bill.

In the RGV, most AC repairs range from $150 to $2,500 depending on the issue. A capacitor replacement typically runs $150–$400. A refrigerant recharge costs $200–$600. A compressor replacement can reach $1,200–$2,800. Labor alone can account for up to 50% of the total repair cost. South Texas heat puts extreme stress on systems, so catching problems early saves significant money. At Cool Aid Air Conditioning, we provide upfront pricing before any work begins.

Start by verifying their Texas ACR license — it is required by law. Then check Google reviews for consistent 4.5-star ratings. Local RGV companies understand extreme South Texas weather conditions and offer faster response times and transparent, localized pricing. Always get a written estimate before work starts. A trustworthy company presents multiple equipment options and explains each one clearly. Cool Aid Air Conditioning does exactly that — every time.

This is one of the most common calls we receive across the RGV. The most frequent 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 caused by restricted airflow. When refrigerant lines become worn out, leaks may occur — causing low internal pressure that makes your system freeze up entirely. In South Texas heat, any one of these issues escalates fast. Call Cool Aid Air Conditioning for same-day diagnostics before small problems become expensive repairs.

Yes. We understand that a major AC repair or full system replacement is an unexpected expense for most families and businesses in the RGV.
