A/C LOW-PRESSURE SWITCH — PROTECTING YOUR COOLING SYSTEM

A/C LOW-PRESSURE SWITCH — PROTECTING YOUR COOLING SYSTEM

The low-pressure switch is an important safety device that monitors refrigerant pressure on the low side of your A/C system. If the pressure drops below a safe level, the switch can shut the system down to help protect the compressor and other major components.

✔ Monitors low-side refrigerant pressure
✔ Helps protect the compressor
✔ Prevents operation under unsafe conditions
✔ Helps detect possible refrigerant problems
✔ Reduces unnecessary system strain
✔ Supports reliable cooling performance

⚠️ Low refrigerant pressure may be caused by a refrigerant leak, restricted airflow, a dirty filter, a frozen evaporator coil, or a refrigerant restriction.

Common warning signs include:

• A/C repeatedly shutting off
• Warm or inconsistent airflow
• Ice forming on the refrigerant line or evaporator coil
• System short-cycling
• Weak cooling performance
• Compressor failing to start

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

Protect your compressor and cooling system with professional A/C service.

A/C DRAIN PAN — PROTECTING YOUR HOME FROM WATER DAMAGE

A/C DRAIN PAN — PROTECTING YOUR HOME FROM WATER DAMAGE

Your A/C drain pan collects condensation produced by the evaporator coil and directs the water toward the condensate drain line. Although it may seem like a simple component, it plays an important role in protecting your system and home.

✔ Collects condensation from the evaporator coil
✔ Helps direct water into the drain line
✔ Reduces the risk of ceiling and property damage
✔ Helps prevent water from reaching electrical components
✔ Supports proper moisture removal
✔ Protects the area surrounding your indoor unit

⚠️ A rusted, cracked, damaged, incorrectly sized, or improperly installed drain pan can allow water to overflow or leak into your home.

Common warning signs include:

• Water around the indoor unit
• Ceiling stains or water damage
• Rust or corrosion on the pan
• Musty odors near the system
• Standing water in the emergency pan
• Frequent activation of the float switch

Regular A/C inspections can identify drainage problems before they cause expensive damage. The pan, drain line, and float switch should all be properly installed and working together.

Protect your A/C system and your home with a properly functioning drain pan.
