10 Common Reasons that your AC is not Turning On

No air conditioner owner wants to see an AC system malfunction when they need it the most. An air conditioner that does not switch on is no less than a big metal box taking up space in your home. As the owner, you need to know the possible reasons why your air conditioner is malfunctioning.

You can contact a reputed AC company in Wesley Chapel to understand your air conditioner better, but knowing the basics of the system will help you save money and time. Here are some reasons and what you can do to fix them:

A Malfunctioning Thermostat

As you know, the thermostat connected to your air conditioner signals your system the temperature it must maintain in your home. However, your air conditioner will not switch on if the thermostat malfunctions due to dead batteries or problems with wiring. Check the thermostat or install a smart thermostat.

Indoor Disconnect Switch

If you have children at home, they may have accidentally turned off the disconnect switch of your air conditioner with their play toys. Ensure that the children stay away from electrical components and check the disconnect switch to resume the function of your AC system.

Outdoor Disconnect Switch

Similar to the indoor disconnect switch, an outdoor disconnect switch supplies power to your air conditioner. There are several reasons why it could turn off. You can easily find it and reset it if applicable.

Tripped Circuit Breaker

The circuit breaker of your air conditioner trips when there are power or voltage problems. It ensures that your air conditioner does not receive too much electricity that may damage its components. Check the circuit breaker for tripping, and flip it back on.

Blown Fuse

You can take care of a tripped circuit breaker yourself, but you need to contact a professional for a blown a fuse. A professional will install a new fuse in order for your air conditioner to resume working. Contact a technician from your nearby HVAC company if a blown fuse is the reason your air conditioner isn’t turning on.

Blown Transformer

A transformer is an important part of your air conditioner, which can stop the system from turning on if it malfunctions. You should not try to fix or replace it yourself as you may get an electric shock, or you may damage the other components of your system.

Capacitor Issues

The capacitors present in your air conditioner are its starting elements. If the capacitors malfunction, your air conditioner will not turn on despite how often you try to switch it on. A capacitor replacement job needs a professional who provides air conditioner installation services in Wesley Chapel, FL.

Dirty Coils

The coils in your air conditioner are in two areas, the indoor and outdoor unit. Over time, these coils collect dirt. If the dirt remains long, the system will stop working. Clean your air conditioner regularly to avoid this issue.

Dirty Air Filters

Air filters purify the indoor air and maintain proper indoor air quality levels in your home. Air filters get clogged due to dirt and dust settlement on the surface. If they remain dirty for a long time, your air conditioner will not turn on.

Unexpected Damage

An air conditioner can face damage from external factors like foreign objects or accidents. Owners should take proper measures to prevent such damage like they should cover the condenser unit to avoid damage due to leaves and twigs.


These were a few factors that may hinder your air conditioner from working properly. Several other reasons and details will not allow your air conditioner to turn on. Franks Air Conditioning & Heating technicians are well versed with these problems and here to assist you.
