Expert Central AC Repair Solutions in Plano, TX
Central air conditioning systems are built to handle the demands of North Texas heat, but even the most reliable equipment can develop problems over time. At Trotter Air Services, we approach every repair call with the same methodology: thorough diagnostics first, then a clear explanation of what we found, followed by an honest recommendation on how to fix it. We have been doing this since 1970, and that process has never let us down.

- Post-repair testing - After every repair, we run your system through a full cycle to confirm everything is operating within manufacturer specifications.
Common Central AC Problems We Fix in North Texas
In over 50 years of repairing air conditioners across the DFW Metroplex, we have seen just about every issue a central AC system can develop. Here are the most frequent problems our Plano customers call us about:
Refrigerant Leaks and Low Charge
Low refrigerant is one of the most common reasons an AC system stops cooling effectively. If your system is low on refrigerant, it means there is a leak somewhere - simply adding more refrigerant without fixing the leak is a temporary fix that wastes money. We locate the leak, repair it, and recharge the system to the correct level. If your home has areas that a central system cannot reach efficiently, a mini-split installation may be worth considering alongside the repair.
Compressor Failures
The compressor is the heart of your AC system. When it fails, the entire system stops cooling. Compressor issues can stem from electrical problems, refrigerant issues, or simply age and wear. Our technicians can determine whether a compressor repair or replacement makes the most sense for your specific situation.
Frozen Evaporator Coils
When your evaporator coil freezes, your system cannot absorb heat from your home's air. This is usually caused by restricted airflow, low refrigerant, or a malfunctioning blower motor. We identify the root cause and address it so the problem does not keep coming back.
Capacitor and Contactor Failures
Capacitors and contactors are electrical components that help start and run your compressor and fan motors. North Texas heat puts extra stress on these parts, and they are among the most frequently replaced components in AC systems in our area. We carry common capacitors on our trucks for fast replacement.
Thermostat Issues
Sometimes the problem is not with the AC unit itself but with the thermostat. Faulty wiring, dead batteries, miscalibrated sensors, or an outdated thermostat can all cause your system to behave erratically. We troubleshoot the entire control circuit to pinpoint the issue.
Drainage Problems
Your AC system produces condensation that drains through a condensate line. In the humid North Texas climate, these lines can clog with algae and debris, leading to water damage or system shutdowns triggered by the safety float switch. We clear drain lines and install preventive measures to reduce future blockages.
Fan Motor and Blower Issues
Both the condenser fan (outdoor unit) and the blower motor (indoor unit) are critical to moving air through your system. Bearings wear out, motors overheat, and belts slip - especially under the sustained load of a Texas summer. We repair or replace these components to restore proper airflow.
AC Repair Cost in Plano, TX
Air conditioning repair costs in Plano vary depending on which component has failed, the age and brand of your system, and how long the problem has gone unaddressed. The table below reflects typical ranges for the most common repairs our technicians perform across the DFW area. These are general reference ranges - your actual cost depends on your specific system and situation. We provide a written price before any work begins.
| Repair Type | Typical Cost Range |
|---|---|
| Service Call / Diagnostic | Call for quote |
| Capacitor Replacement | Call for quote |
| Refrigerant Recharge | Call for quote |
| Condenser Fan Motor | Call for quote |
| Evaporator Coil Replacement | Call for quote |
| Compressor Replacement | Call for quote |
North Texas summers mean AC systems work hard from May through October, and the sustained workload accelerates wear on electrical components like capacitors and contactors. Catching a small issue early - before it becomes a compressor failure - is almost always the more cost-effective path. Service Finance financing is available for larger repairs. Call 972-424-9233 for a same-day diagnostic.

AC Running But Not Cooling? Here Is How to Diagnose It
When a central AC runs but does not cool, the cause is almost always one of five things: a thermostat issue, a clogged filter, a tripped breaker, a failed compressor or capacitor, or ice buildup on the evaporator coil from a refrigerant leak. Here is how to work through them before calling for service.
- Check the thermostat. Confirm it is set to COOL, the setpoint is below room temperature, and the batteries are not dead. A failed thermostat is the most common false-alarm AC service call we respond to.
- Inspect the air filter. A clogged filter restricts airflow across the evaporator coil and can stop cooling entirely. If the filter has not been changed in 60 or more days, replace it and run the system for 15 minutes before calling.
- Check the breaker for the outdoor unit. If the outdoor condenser is not running but the indoor blower is, a tripped breaker is the likely cause. Reset it once. If it trips again, stop and call - repeated trips indicate an electrical fault.
- Listen for the compressor. Stand near the outdoor unit. If the fan is spinning but you hear no compressor hum, the compressor or its capacitor has likely failed. This requires a technician - do not attempt to reset a failed compressor.
- Check for ice on the indoor coil or refrigerant lines. Visible ice means the system has either low refrigerant from a leak or restricted airflow. Turn the system off, switch the fan to ON to thaw the coil, and call for emergency AC repair before the leak grows.
If you have worked through all five steps and your system still is not cooling, the problem requires professional diagnosis. Call Trotter Air Services at 972-424-9233 for same-day service in Plano and the surrounding DFW area.

North Texas Climate and Your Central AC System
Living in Plano, TX and the surrounding DFW Metroplex means your central air conditioning system works harder and longer than units in most other parts of the country. Understanding how our local climate affects your equipment can help you make better decisions about repairs and maintenance.
Summer Demands in the DFW Metroplex
North Texas summers regularly push temperatures into triple digits. Your AC system may run 12 to 16 hours a day during peak summer months, putting enormous strain on compressors, fan motors, capacitors, and electrical connections. This sustained workload is why AC failures spike in July and August - the components are simply working at or near their limits for extended periods.
Seasonal Temperature Swings
The DFW area also experiences significant temperature swings in spring and fall. Your system might cycle between heating and cooling within the same week - or even the same day. These rapid transitions stress components differently than sustained operation, and they can reveal developing problems before the real summer heat arrives.
Humidity and Drainage Concerns
North Texas humidity, particularly in late spring and early summer, puts extra demand on your system's dehumidification capacity and drainage infrastructure. Clogged condensate lines are one of the most common service calls we handle during the humid months, and they can lead to water damage if not addressed promptly.
Improving your home's air filtration system can also help reduce the strain on your AC by keeping coils and components cleaner, which improves efficiency and reduces the likelihood of breakdowns.

We believe everyone deserves a comfortable home, regardless of budget constraints. That's why we work with trusted financing providers to make quality HVAC equipment accessible to more families across Plano, TX and Greater Dallas.

Frequently Asked Questions About Central AC Repair in Plano, TX
As a general rule, if your system is less than 10 years old and the repair cost is reasonable relative to the overall value of the equipment, repairing usually makes sense. If your system is 15 years or older and you are facing a major repair like a compressor replacement, it may be more cost-effective to invest in a new, high-efficiency system. Our technicians will give you an honest assessment based on your specific situation - we never push replacements when a repair will do.
We prioritize repair calls and typically offer same-day or next-day service in Plano and the surrounding areas. During peak summer months, our schedule fills quickly, so calling as soon as you notice a problem gives us the best chance to get to you quickly.
We repair all major brands of central air conditioning systems. Our deepest expertise is with Armstrong as a ProTeam dealer. We also regularly service and repair Carrier, Trane, Lennox, Rheem, Goodman, and other popular brands.
Yes. We understand that AC failures in North Texas can be more than just uncomfortable - they can be dangerous, especially for elderly residents, young children, and pets. We do our best to accommodate emergency calls and get your system running as quickly as possible.
Warm air from your vents can be caused by several things: low refrigerant from a leak, a failed compressor, a malfunctioning thermostat, a tripped breaker, or even a dirty air filter restricting airflow across the evaporator coil. Our technicians systematically test each possible cause to identify the exact issue.
We recommend having your central AC system professionally serviced at least once a year - ideally in the spring before the summer heat arrives. Regular maintenance catches small problems before they become big ones and helps your system run at peak efficiency. Our maintenance plans make this easy and affordable.
When your air conditioner runs but does not cool, the most likely causes are a refrigerant leak, a failed capacitor or compressor, a clogged air filter blocking airflow across the evaporator coil, a thermostat set incorrectly, or a tripped breaker on the outdoor unit. See the full five-step diagnosis above for how to work through each cause before calling. If the system has ice forming on the coil or lines, shut it down immediately and call - running a frozen system accelerates damage.
AC air conditioning repair costs in Texas vary by what has failed. A simple capacitor replacement is far less expensive than a compressor or evaporator coil replacement. See the cost table above for a breakdown by repair type. We provide a written price before any work starts, and Service Finance financing is available for larger repairs. Call 972-424-9233 for a same-day diagnostic in Plano and the surrounding DFW area.
The general rule is the age-times-cost test: if your system is more than 10 years old and the repair cost exceeds 50 percent of a new system's price, replacement is usually the smarter investment. A compressor failure on a 15-year-old system is a clear replacement signal - the compressor is the most expensive component, and the rest of the system has the same lifespan. Our technicians will give you a straight answer on repair vs. replace based on your specific system, not a sales push.
Yes, we partner with Service Finance to provide flexible financing options for AC repairs and replacements. This ensures that a broken air conditioner does not leave you stranded financially. We can discuss your options during the service call.
