5 Reasons Why Your Air Conditioner Won’t Turn On

Your air conditioner needs to provide reliable comfort through sweltering Texas summers. So, what do you do when your air conditioner won’t turn on? There are a variety of reasons why this can happen, so it’s best to call for a professional technician. They have years of experience determining the source of these problems, and specialized tools for effective solutions. Experts like the team at Diamond Blue Air can offer professional air conditioning repair in Carrollton, TX.

We’d like to provide a few of the most common reasons your air conditioner won’t turn on. If you can discover the source of the problem on your own, your Diamond Blue technician can proceed with repairs more quickly. Any time and money we save along the way is yours!

Here are 5 common reasons why your air conditioner won’t turn on.

The Air Filter

The air filter is one of the most important parts of any air conditioning system. It prevents dust and debris from circulating through your HVAC equipment. Over time, the debris collects in the filter. Depending on the design, it will have to be either replaced or washed. If the filter is left dirty or clogged, it can stop your air conditioner from turning on.

Making sure the filter is regularly replaced or cleaned is a big part of responsible air conditioning maintenance in Carrollton, TX. The pros at Diamond Blue Air can also support your HVAC equipment with quality maintenance.

The Evaporator / Condenser

These components are central to how your air conditioning captures and transports heat. Dirt and grime buildup will gradually reduce their efficiency, before stopping your air conditioner from working at all.

Like the air filter, they should be kept clean for the best results. We offer seasonal tune-ups that include a thorough cleaning of components like the evaporator coils and condenser lines. But if they experience severe damage, resolving the problem becomes more complicated. For certain components, you may be better off replacing the air conditioner entirely. When considering whether to repair vs. replace an air conditioner, Diamond Blue can help. Our technicians will recommend the most efficient replacement models.

The Thermostat

Your thermostat controls when and how your HVAC system functions from day to day. Sometimes the reason your air conditioner won’t turn on is simply because the thermostat’s settings are incorrect. Resetting or adjusting them can resolve the problem, but not if the thermostat itself is malfunctioning. During air conditioning repair, we’ll check your thermostat for signs of trouble.

An Electrical Problem

Several of the most common culprits are the electrical components of your HVAC system, such as wiring, fuses and the circuit breaker. If these are damaged or disconnected, it can keep your air conditioner from turning on.

A tripped breaker is a comparatively easy fix and can be done on your own. A blown fuse is more complex, as is faulty or damaged wiring. So is testing a compressor that is going bad. It’s best to leave these kinds of problems to professional repair technicians. They can provide safe, affordable solutions.


While the damage from a leak is frustrating enough, the type of leak may also prevent your air conditioner from turning on. This is a common result of coolant leaks. For older models, this can even result in having to replace your air conditioner entirely.

Older systems use Freon, a coolant that is currently being phased out. Technicians will be unable to replenish the Freon in the future and the cost of Freon is increasing significantly. Also, retrofitting an older system for alternate refrigerants is an expensive process. Upgrading to a newer model is generally the best option. Diamond Blue Air offers the best air conditioning installation in Carrollton, TX. We can make sure the process is seamless and hassle-free.
