What to Check When Your Air Conditioner Won't Start

Expert Insights from Airview AC

At Airview AC, we understand how frustrating it can be when your air conditioner won't turn on, especially in the Texas heat. Let’s walk through some common reasons why your AC might be acting up and what you can do to get it back on track.

Common Problems and Solutions

1. Thermostat Issues

Thermostat Settings

First things first, let's check your thermostat. Ensure it's set to “cool” and the temperature is set a few degrees lower than your home's current temperature. Sometimes, a simple adjustment is all it takes to get things going.

Thermostat Replacement

If your thermostat is unresponsive or showing incorrect temperatures, it might be time for a replacement. A faulty thermostat can prevent your AC from turning on, so consider having a professional look at it.

2. Electrical Problems

Tripped Circuit Breaker

Your AC unit relies on electricity to function. Check your electrical panel for any tripped circuit breakers. If the breaker for your AC has flipped to the “OFF” position, this could be the culprit. Reset it and see if your AC starts up.

Blown Fuses

Older homes might experience blown fuses more frequently. A blown fuse can cut power to your AC unit. If this is the case, a professional technician can replace the fuse and get your system back online.

3. Airflow Problems

Clogged Air Filters

Air filters play a crucial role in your AC’s performance. Over time, they can become clogged with dust and debris, restricting airflow and causing the unit to work harder than it should. This can eventually lead to your AC shutting down.

Dirty Evaporator Coils

Evaporator coils are essential for cooling the air. If they become dirty, they can’t function efficiently and might cause your system to fail. Regular cleaning and maintenance are key to avoiding this issue.

Dirty Condenser Lines

Condensate lines can also get clogged with algae, dust particles and other debris. When these lines are blocked, your AC has can’t drain properly, which can result in water damage or inefficient operation. Professional cleaning can prevent this from happening.

4. Mechanical Failures

Damaged or Broken Motor

If your AC is making strange noises or not turning on at all, the motor could be damaged. A broken motor will need to be inspected and possibly replaced by a professional.

Refrigerant Leaks

Refrigerant is essential for cooling your air. If there's a leak, your AC won't be able to cool effectively, and it might not turn on at all. A technician can diagnose and fix refrigerant leaks, ensuring your system runs smoothly.

5. Control Issues

Faulty Thermostat

Sometimes, the issue lies with the thermostat itself. If it’s not reading the correct temperature, it won’t signal the AC to turn on. Replacing a faulty thermostat can solve this problem.

Wiring Issues

Wiring problems are less common but can be a serious issue. If all other possibilities have been ruled out, it might be worth having an electrician check the wiring to and from your AC unit.
