WHY YOUR A/C CONTACTOR IS IMPORTANT

WHY YOUR A/C CONTACTOR IS IMPORTANT

Your A/C contactor is a small but very important electrical component that helps your system turn on and off properly. When your thermostat calls for cooling, the contactor sends power to the compressor and outdoor fan motor so your A/C can start working.

A properly working contactor helps:

✔ Turn your A/C on and off correctly
✔ Support the compressor and fan motor
✔ Help maintain reliable cooling
✔ Reduce strain on electrical components
✔ Support overall system performance
✔ Help prevent unexpected breakdowns

When the contactor starts to fail, you may notice:

⚠ A/C not turning on
⚠ Outdoor unit not running
⚠ Clicking noises
⚠ Intermittent cooling
⚠ Short cycling
⚠ Extra wear on major system components

Because the contactor works every time your A/C starts, it can wear down over time—especially during hot weather when your system runs more often.

Regular maintenance helps detect worn contactors early and can help prevent bigger repairs or a complete system breakdown.

A healthy contactor helps keep your A/C running safely, reliably, and efficiently.

LOW PRESSURE SWITCH: SMALL PART, BIG PROTECTION FOR YOUR A/C

LOW PRESSURE SWITCH: SMALL PART, BIG PROTECTION FOR YOUR A/C

Your A/C low pressure switch is a safety component that helps protect your cooling system when refrigerant pressure drops too low. It may be a small part, but it plays an important role in protecting your system from bigger damage.

A properly working low pressure switch helps:

✔ Protect the compressor
✔ Detect low-pressure problems
✔ Help prevent system damage
✔ Support safer A/C operation
✔ Improve system reliability
✔ Warn of possible refrigerant or airflow issues

If the low pressure switch is tripping, it may be a sign of:

⚠ Low refrigerant charge
⚠ Refrigerant leaks
⚠ Restricted airflow
⚠ Frozen evaporator coil
⚠ Poor system performance
⚠ Other cooling issues that need attention

Because the compressor is one of the most important parts of your A/C system, having a working low pressure switch can help prevent more expensive repairs.

A healthy low pressure switch helps protect your comfort and keeps your A/C system safer and more reliable.

COMPRESSOR: THE HEART OF YOUR A/C SYSTEM

COMPRESSOR: THE HEART OF YOUR A/C SYSTEM

Your A/C compressor plays a major role in keeping your home cool. It helps circulate refrigerant through the system so heat can be removed from your home and cool air can flow indoors.

A healthy compressor helps:

✔ Keep your home cool and comfortable
✔ Support strong cooling performance
✔ Help your system run efficiently
✔ Maintain proper refrigerant movement
✔ Reduce stress on other components
✔ Support reliable operation during hot weather

When the compressor is under stress or starting to fail, your A/C may blow warm air, make unusual noises, struggle to start, or stop cooling completely.

Because the compressor is one of the most important and expensive parts of your system, regular maintenance is very important. Catching small problems early can help prevent costly repairs.

Take care of your compressor — it helps take care of your comfort.
