Understanding Your Thermostat

What Does “Cool On” Mean?

When you see “Cool On” flashing on your thermostat, it usually means that your AC is trying to cool your home. The flashing message is a signal that the system is in the process of starting up. It might be waiting to make sure everything is ready before it starts cooling. If you notice the flashing often, or for a longer period of time, schedule an AC repair with Shadrach today for quick service and peace of mind.

Why Is My Thermostat Flashing Cool On?

The flashing “Cool On” can happen for a few reasons:

1. Delay Mode: Many thermostats have a built-in delay to protect the AC unit. This delay usually lasts about 5 minutes. It helps prevent damage to the compressor by not letting it turn on and off too quickly.

2. System Check: The thermostat might be checking if everything is working properly. It makes sure that the AC can safely start cooling.

3. Power Issues: Sometimes, a brief power outage or a power surge can make the thermostat reset. It will flash “Cool On” while it gets back to normal.

Common Problems and Fixes

AC Not Cooling

If “Cool On” is on constant and your AC is not cooling, there could be several reasons. Let’s look at some common problems and how to fix them.

1. Check the Thermostat Settings

First, make sure the thermostat is set to “Cool” and that the temperature setting is lower than the current room temperature. If it’s not set correctly, the AC won’t turn on.

2. Inspect the Air Filter

A dirty air filter can block airflow and make it hard for your AC to cool your home. Check the filter and replace it if it’s dirty. This is an easy fix that can improve cooling right away.

Regular maintenance ensures your AC is always ready when you need it. Schedule AC maintenance with Shadrach Plumbing & Cooling today.

3. Look at the Circuit Breaker

Your AC might not be getting power. Check the circuit breaker box and make sure the breaker for the AC is in the “On” position. If it’s tripped, switch it off and then back on.

4. Examine the Outdoor Unit

Sometimes, the outdoor unit can get blocked by leaves, dirt, or other debris. Make sure the area around the unit is clear so that it can work properly.

5. Call a Professional

If you’ve tried these steps and your AC is still not cooling, it might be time to call a professional. There could be a bigger problem with your AC unit that needs expert help. Shadrach has skilled technicians ready to inspect your AC, diagnose the issue, and complete an AC repair.
