🌸❄️ SPRING WARNING: Don’t Skip the Low-Pressure Switch Check! ❄️🌸

Before the Houston heat ramps up, it’s smart to check your A/C’s low-pressure switch. This safety switch helps protect your system by shutting it down when suction pressure drops too low—often preventing coil freeze-ups and compressor damage.

✅ Why it matters in spring

Spring weather can be tricky: warm days, cooler nights, and rising humidity. If airflow is restricted or refrigerant is low, the system can run with low suction pressure, which can lead to ice on the coil and poor cooling. The low-pressure switch may trip to protect the equipment—sometimes showing up as intermittent cooling or random shutdowns.

⚠️ Common causes of low-pressure trips

• Low refrigerant (possible leak)
• Dirty air filter or restricted airflow
• Dirty evaporator coil
• Blower issues (weak motor/capacitor)
• Cold outdoor temps + running cooling (in some cases)

🚨 Signs you may have a low-pressure issue

✅ Weak cooling or long run times
✅ Ice on the indoor coil or copper lines
✅ System shuts off and won’t stay running
✅ Indoor blower runs but cooling is inconsistent
✅ Fault code related to “low pressure” (tech diagnosis)

🧰 During a spring check-up we verify airflow, inspect filters/coils, check refrigerant performance, and confirm safety switches are operating correctly—so you’re ready for summer.
