A/C MAINTENANCE — KEEP YOUR SYSTEM RUNNING STRONG

A/C MAINTENANCE — KEEP YOUR SYSTEM RUNNING STRONG

Regular A/C maintenance helps your cooling system operate safely, efficiently, and reliably—especially during the intense Texas heat.

✔ Improves cooling performance
✔ Helps lower energy consumption
✔ Reduces unnecessary stress on components
✔ Identifies potential problems early
✔ Helps prevent unexpected breakdowns
✔ Improves indoor air quality
✔ May extend the life of your equipment

During professional maintenance, the technician can inspect electrical components, check refrigerant readings, clean essential parts, verify airflow, inspect the drain system, and confirm that the system is operating properly.

⚠️ Skipping maintenance can lead to dirty coils, clogged drain lines, weak airflow, higher electric bills, water damage, and costly equipment failures.

Protect your comfort with professional A/C maintenance from Uptown Heating & Air Conditioning.

A/C HIGH-PRESSURE SWITCH — PROTECTING YOUR SYSTEM FROM EXCESSIVE PRESSURE

A/C HIGH-PRESSURE SWITCH — PROTECTING YOUR SYSTEM FROM EXCESSIVE PRESSURE

Your A/C high-pressure switch monitors refrigerant pressure on the high side of the system. If the pressure rises above a safe level, it can shut down the equipment to help protect the compressor and other important components.

✔ Monitors high-side refrigerant pressure
✔ Helps protect the compressor from damage
✔ Stops operation during unsafe pressure conditions
✔ Reduces stress on major components
✔ Helps prevent overheating
✔ Supports safe and reliable cooling

⚠️ Excessive pressure can be caused by a dirty condenser coil, failed condenser fan motor, restricted airflow, excess refrigerant, or an internal refrigerant restriction.

Common warning signs include:

• A/C repeatedly shutting off
• System short-cycling
• Outdoor unit overheating
• Fan motor not operating
• Warm or inconsistent airflow
• Compressor struggling to start

Never bypass a high-pressure switch. If it shuts your system down, a professional technician should identify and correct the underlying problem.

Protect your compressor with professional diagnostics from Uptown Heating & Air Conditioning.

A/C CONTROL BOARD — THE BRAIN BEHIND YOUR COMFORT

A/C CONTROL BOARD — THE BRAIN BEHIND YOUR COMFORT

Your A/C control board coordinates important electrical functions throughout the system. It receives signals from the thermostat and helps control the blower motor, compressor, fan, and other components in the proper sequence.

✔ Communicates with the thermostat
✔ Controls important system functions
✔ Helps components operate in the correct sequence
✔ Supports consistent and reliable cooling
✔ Monitors certain safety controls
✔ Helps prevent improper system operation

⚠️ A failing control board may cause your A/C to stop working, run intermittently, fail to start, display error codes, or prevent the blower or outdoor unit from operating correctly.

Because other problems can imitate control-board failure—including loose wiring, a failed transformer, motor issues, or incorrect blower connections—a complete professional diagnosis is essential before replacing the board.

Keep your A/C operating correctly with professional service from Uptown Heating & Air Conditioning.
