AC not cooling is the call we take most in El Campo, TX, and it arrives the same way every time. The system runs. The air is not cold. The house has been climbing since noon. The useful question is not who can come out. It is what actually broke, and whether the repair is worth paying for.
Key Points
- A failed capacitor is the most common cause of an AC not cooling, and the part rides on the truck.
- A clogged condensate drain shuts a system down with nothing actually broken. It is one of the cheapest fixes there is.
- Four checks you can run yourself solve a share of AC not cooling calls: thermostat, breakers, filter, and clearance around the outdoor unit.
- A diagnostic visit from Cannell costs $85. Service Agreement members pay $75.
- Multiply your system’s age by the repair estimate. If it clears about $5,000, replacement is usually the better value.
Why AC Not Cooling Happens Faster on the Gulf Coast
An air conditioner here does not get an off-season. It runs through a March warm spell, holds a house against July humidity, and still works in October. Three local conditions drive almost every service call.
Runtime. A system that runs most of the year piles up compressor hours fast. Wear that shows up in year fifteen up north shows up sooner in Wharton County.
Humidity. Your air conditioner is a dehumidifier that happens to make cold air. It pulls gallons of water out of your home’s air every day. All of it leaves through one condensate drain.
Salt air. Closer to Palacios and Port Lavaca, outdoor coils breathe salt year-round. Corroded fins and corroded electrical contacts trace back to the same cause.
None of that dooms a system. It means the maintenance schedule that works in a dry climate does not work here.
7 Causes of an AC Not Cooling
1. A failed capacitor
The most common cause of all. You hear the outdoor unit hum but the fan does not spin. Or the fan spins only after you nudge it. It is a small part, and we carry it.
2. A clogged condensate drain
Algae and dust plug the line. Water backs up. The float switch does its job and cuts the system off. Nothing is broken; the house just gets warm. Annual maintenance prevents this one outright.
3. A dirty or frozen evaporator coil
Restricted airflow drops the coil below freezing. Ice forms, airflow drops further, and cooling stops. The usual cause is a filter nobody changed. Switch the system to fan only, let it thaw, and replace the filter. If it freezes again, the problem runs deeper.
4. Low refrigerant, which means a leak
Refrigerant is not a consumable. A system does not use it up. If yours is low, it leaked out. Adding more without finding the leak means the same AC not cooling call next season. Ask your technician to find it.
5. A failed contactor
The contactor is the relay that switches the outdoor unit on. Pitted or corroded contacts either stop the unit from starting or keep it from shutting off. Coastal air speeds this up.
6. A failing blower motor
The air handler runs loud, weak, or not at all. This is where the repair versus replacement math starts to matter.
7. A failed compressor
The expensive one. On a system still under manufacturer warranty, replacing a compressor can make sense. On a fifteen-year-old system out of warranty, your money usually goes further toward a new system.
4 Things to Check Before You Call
None of these needs tools. Any one of them can turn an AC not cooling call into a five-minute fix.
- Thermostat. Set to COOL, set below room temperature, with fresh batteries if it takes them.
- Breakers. Air conditioners have two. One feeds the indoor air handler, one feeds the outdoor condenser. Check both.
- Filter. If you cannot remember replacing it, replace it. Filters load up faster here than the box claims.
- The outdoor unit. Clear grass clippings, leaves, and anything stacked against it. The unit needs open air on every side to dump heat.
If the house still will not cool, the fault lies with the equipment. That is when you call a technician.
What It Costs to Fix an AC Not Cooling
Cannell charges an $85 diagnostic fee. Service Agreement members pay $75. That fee covers a technician finding the real fault and telling you what the fix takes. You do not get a guess from the driveway.
Two more numbers matter if you carry a Service Agreement:
- 20% off repair labor and 10% off replacement parts. On a $400 blower motor, that is $40 back on the part before the labor discount lands.
- A one-year labor warranty. If the same problem returns within that year, we come back and re-diagnose it at no charge.
We stock our trucks so an AC not cooling call gets finished on the first trip. About 99% of our service calls get repaired on the first visit.
We will not quote a repair before someone looks at the system. Our pricing stays competitive and fair with no hidden or surprise costs. The only way to keep that promise is to diagnose first and price second.
Repair or Replace? Run the Numbers
No decision that follows an AC not cooling call puts more pressure on a homeowner. Here is how to make it without anyone selling you.
Age. Most residential systems in this climate deliver 10 to 15 years of service. Under 10 years, repair almost always wins. Past 15, every repair buys borrowed time.
The cost-versus-age test. Multiply the age of the system by the repair estimate. If the result clears about $5,000, replacement is generally the better value. A 12-year-old system with a $600 repair comes to $7,200. That one deserves a serious conversation. A 6-year-old system with the same repair comes to $3,600, so you fix it.
Refrigerant type. If your system runs on R-22, that matters. Production and import of R-22 in the United States ended January 1, 2020. The only supply left is recovered and reclaimed. A major R-22 leak on an older system is usually the moment to replace.
Call frequency. An AC not cooling twice in one season is a pattern, not bad luck.
Your electric bill. A system losing efficiency shows up on the bill before it breaks down. Compare this July to last July. If you do replace the system, read ENERGY STAR’s heating and cooling guidance first. Correct sizing and installation matter as much as the efficiency rating on the box.
At Cannell, the owner or a technician walks you through this, not an aggressive salesperson. The estimate is free. That is the whole point of doing it this way. You get an answer from someone whose job is the equipment.

How to Avoid the Next AC Not Cooling Call
Most causes on this list start as something a tune-up catches early. A drain line about to plug. A contactor pitting. A capacitor reading low. A coil losing capacity under a layer of dirt.
Our Service Agreement covers two performance tune-ups a year, one before cooling season and one before heating season. It also includes priority service, the $75 diagnostic rate, and energy-saving coil cleaning. You get 20% off repair labor, 10% off parts, and 5% off a new unit when that day comes. Ask us for current pricing.
Between visits, two things matter most, and you control both. Change the filter on schedule. Keep two feet of clear space around the outdoor unit.
