Why Won’t My AC Turn On?


No matter how long you have lived in San Antonio, nobody can get used to the searing heat from the hot Texas sun during the summers. You need to have a properly functioning air conditioning system to ensure your comfort and sanity as the temperatures go higher and higher every day. If your air conditioner isn’t working, especially in the summers, your home can become unbearably hot.

Nothing could be worse than coming home after a long and hot day in San Antonio only to find that your air conditioner refuses to turn on. An air conditioner that doesn’t turn on is not entirely uncommon. There are a few easy steps to figure out why your air conditioner might not be turning on.

You might need to schedule services for repairs to get it back working. Depending on how bad the situation is, you might even need to call us for air conditioning installation in San Antonio, TX, to replace your old unit.

We will tell you about some of the reasons your AC won’t turn on so that you can make a more informed decision on what to do next.

Reasons Your AC Won’t Turn On

Here are some of the most common reasons your AC won’t turn on.

1. A blown fuse

It is possible that the air conditioner won’t turn on at all because it has blown a fuse. Most modern air conditioners rely solely on your electrical panel, a.k.a your circuit breaker panel. However, some older models of air conditioners do have electrical fuses in them. If the circuit breaker hasn’t tripped (more on that in a moment), then it may instead be an internal fuse that will need to be replaced by a professional.

2. The circuit breaker tripped

Circuit breakers protect your home’s electrical appliances and wiring by tripping if there is too much current flow. This is a vital component that protects your home from electrical fires. It is possible that the circuit breaker tripped because you’re using way more appliances simultaneously, or an appliance is too old and is using too much electricity.

Try resetting the circuit breaker and turning on the AC. If the circuit breaker trips again, there is something wrong with the air conditioner, and you need to get it examined by a professional.

3. Dirty air filter

When was the last time you changed your air conditioner’s air filter? There is a chance that the air filter is completely clogged. When the air filters are clean, your AC absorbs the humidity from your home. The water droplets fall into a condensation tray and then go out through the drain lines.

Without proper airflow, the water droplets will freeze, covering the coils with ice, causing the air conditioner to shut down before it can complete its cooling cycle. Replacing the air filters could do the trick.

Is Your AC Not Turning On?

While most air conditioners can last for up to 15 years, even the most well-maintained systems require occasional repairs. Working with a reliable air conditioning company is crucial to ensure that your unit provides you the necessary cooling without compromising your comfort.
