What Usually Breaks in Mission Air Conditioners
Mission summers sit in the upper 90s from June through September, with a run of triple digit days in July and August. Systems here work almost nonstop for five months, so the parts that wear out are the ones that start and stop under load: capacitors, contactors, and blower and fan motors. A capacitor is an inexpensive part that can still stop the whole system, which is why a proper diagnosis beats a guess.
Humidity is the other half of the problem. Gulf air keeps indoor moisture high, so condensate drains clog with algae and the float switch shuts the system off to protect your ceiling. A frozen evaporator coil, usually from a dirty filter or weak airflow, looks like a dead AC but often turns out to be a simple fix. Refrigerant leaks happen too, and that is the repair where it pays to hear every option before you decide.
Part Time Residents and Houses That Sit Closed Up
Mission has more RV parks than any other Valley city, around thirty inside the city limits, and a large share of nearby homes belong to Winter Texans who leave for the summer. A house shut up from April to October builds heat and moisture, and the AC may not have run a full cycle in months. If you are coming back for the season, have the system checked a couple of weeks before you arrive instead of the day you land.
Year round residents get the opposite problem. The system never rests, so small faults grow. A new rattle, a hot electrical smell, or an electric bill that climbs with no change in how you use the AC are all reasons to call before the weekend.
Quick Checks Before You Call
None of these replace a technician, but they can save you a visit when the answer is a tripped breaker.
- Make sure the thermostat is set to cool, set below the room temperature, and has working batteries.
- Look at the filter. A clogged filter is the most common reason a coil freezes.
- Check the breaker for the indoor and outdoor units.
- Look for water in the drain pan or a wet spot under the air handler, which points to a clogged drain.
- If you see ice on the lines or coil, switch the system off and let it thaw before you call.
Repair or Replace
A common rule of thumb is to multiply the repair cost by the age of the system in years. If the result is above five thousand dollars, replacement usually makes more sense. A ten year old unit facing a three hundred dollar repair scores three thousand and gets fixed. A fifteen year old unit that needs a four hundred dollar part scores six thousand, and that conversation goes differently. We will tell you honestly which side of the line your system is on.
Age of refrigerant matters too. A system built before 2010 probably runs on R-22, which is no longer produced, so a leak on one of those is usually the moment to replace instead of recharge.

Mission AC Repair FAQs
How much does AC repair cost in Mission?
It depends on the part. Capacitors and contactors sit at the low end, blower motors and compressors at the high end, and refrigerant leaks vary the most. You get a price after the diagnosis and before the work. The service call is free when you have us do the repair.
Why does my AC run but not cool the house?
The common causes are a dirty filter, a frozen coil, a failed capacitor or fan motor on the outdoor unit, low refrigerant, or a blocked outdoor coil. Some of those you can spot yourself and some need gauges, so call and describe what you see.
Is it worth repairing an older AC in Mission?
Often yes. Multiply the repair cost by the system's age in years. Under five thousand dollars usually favors repair. Over that, or if the system uses R-22 refrigerant and is leaking, replacement is usually the better spend.
Do you work on weekends?
Saturday hours are 8 AM to 2 PM and Sunday hours are 9 AM to 2 PM, for scheduled jobs. We do not run after hours emergency calls, so if the AC dies on a Friday evening, call first thing in the morning.
Can you check my house before I get back for the winter?
Yes. Call and describe the house, and we will schedule a visit to run the system and look it over. Doing it in October is easier than doing it in January with a full house.
Do you repair business AC in Mission as well as homes?
Yes. Cool Aid handles residential and commercial AC repair in Mission. Call with the type of equipment and where it is installed so we can plan the visit.
