🔧 August A/C Repair ➡️Second Opinion Saves the Customer From an Unnecessary Replacement

Another A/C repair in the Katy, TX area completed by Cornerstone A/C & Heat!

The homeowner was told by another HVAC company that they needed a new A/C system. They decided to get a second opinion before replacing the entire system.

After properly diagnosing the equipment, we found a refrigerant restriction at the TXV (Thermostatic Expansion Valve) inside the evaporator coil. We confirmed there were no refrigerant leaks and determined the system could be repaired instead of replaced.

✅ Diagnosed refrigerant restriction
✅ Replaced defective TXV
✅ Evacuated the A/C system
✅ Installed a new liquid-line filter drier
✅ Verified system operation
✅ Got the homeowner back up and cooling

That’s what it’s all about proper A/C diagnosis, quality HVAC repair, and taking care of the customer. Not every A/C problem requires a new system.

🚨 OUTSIDE A/C UNIT NOT RUNNING?

Is your A/C not cooling, even though the indoor blower is running? If your outside A/C unit isn’t turning on, the problem could be a failed capacitor, contactor, thermostat issue, tripped breaker, wiring problem, or another electrical or condenser issue.

Before calling for A/C repair in Katy, TX, there are a few safe things you can check yourself.

👉 We created a helpful FAQ explaining why your outside A/C unit may not be running, what you can safely check, and when you should call an HVAC professional.

Late-night A/C emergency call in Katy, TX! 🌙❄️

New customer’s A/C stopped cooling, and after diagnosing the system, we found the compressor was overheating and nearing its maximum amp draw because the condenser coil was completely plugged with debris, restricting airflow.

✅ Thoroughly cleaned the condenser coil
✅ Replaced the air filters
✅ Verified compressor amperage dropped back into the normal operating range
✅ Confirmed the system was cooling properly before leaving

Maintenance is key! A severely clogged condenser coil can cause your compressor to overheat, shortening its lifespan and potentially leading to a repair that can cost thousands of dollars.

Don’t wait until your A/C quits on the hottest day of the year. A professional tune-up can help reduce the risk of unexpected breakdowns, improve efficiency, and keep your system running reliably.
