Why Won’t My Air Conditioner Turn On?

Hi there! We want to help you figure out why your air conditioner won’t turn on. If you live in Glenwood Springs, Roaring Fork Valley, Vail Valley, or the Western Slope areas of Colorado, you know how important a working AC unit is, especially during those warmer summer days. Here at Climate Control Company, we’ve been helping families stay cool since 1956. Let’s dive into some common reasons why your air conditioner won’t turn on and what you can do about it.

Common Reasons Your Air Conditioner Won’t Turn On

Check the Thermostat

The first thing you should do if your air conditioner won’t turn on is to check the thermostat. Make sure it’s set to “cool” and the temperature is set lower than the current room temperature. Sometimes, the simplest solution is the right one. If the thermostat is off or the batteries are dead, your air conditioner won’t get the signal to start. Replace the batteries if needed and make sure everything is set correctly.

Power Problems

Another common issue is a power problem. Check if your system is getting power. Look at the circuit breaker and see if it has tripped. If it has, reset it by flipping the switch off and then back on. Also, check the fuse box. If a fuse is blown, replace it. Make sure the power switch near the air conditioner unit is turned on. Without power, your AC unit won’t turn on.

Clogged Air Filter

A dirty or clogged air filter can cause your air conditioner to stop working. Air filters need to be changed regularly to ensure proper airflow. If the filter is clogged, it can cause the air conditioner to overheat and shut down. Check your filter and replace it if it’s dirty. It’s a good idea to change your air filter every 1-3 months, depending on how often you use your air conditioner, if you have multiple pets, or if any occupants have allergies or other respiratory issues. If any of these apply to your home, you may want to change your air filter more frequently.

Inspect the Condenser Unit

The condenser unit is the part of your air conditioner that sits outside. It can get dirty or clogged with leaves, dirt, and debris. If it’s dirty, it won’t work properly, and your unit might not turn on. Turn off the power to the unit and clean it with a garden hose. Make sure there’s nothing blocking the airflow. A clean condenser unit helps your air conditioner run smoothly.

Check the Drain Line

Your air conditioner has a drain line that removes condensation. If the drain line is clogged, it can cause the air conditioner to stop working. Check the drain line and make sure it’s clear. You can use a wet/dry vacuum to remove any blockages. Keeping the drain line clear helps prevent water damage and keeps your air conditioner working.

Refrigerant Levels

Low refrigerant levels can also cause your air conditioner to stop working. Refrigerant is what cools the air, and if there isn’t enough, your air conditioner won’t be able to cool your home. If you suspect low refrigerant levels, you’ll need to call a professional from Climate Control Company to check and refill it. Handling refrigerant requires special training and equipment.

Faulty Capacitor

The capacitor is a small part that helps start the air conditioner’s motor. If it’s faulty, the motor won’t start, and your system won’t turn on. You might hear a clicking sound when you try to turn it on. A faulty capacitor needs to be replaced by a professional. It’s a quick fix, and your air conditioner will be up and running again.
