There’s nothing worse than having an air conditioner that’s not cooling at all in the middle of a hot Arizona summer. Maybe the only thing more frustrating is trying to figure out why your AC unit just stopped working. The experts at Donley Service Center say there are a few things you can do at home if you’re confronted with an air conditioner not cooling. However, getting in contact with a professional HVAC contractor is always a good bet.


When trying to determine what’s wrong with your unit, always start with the easiest solution. First of all, make sure your air conditioner thermostat is set to “cool.” It sounds like a no-brainer, but it’s easy to forget, especially when you haven’t needed to use the AC all winter long. Make sure it is set to “cool” and that it’s set a few degrees below room temperature.

If your air conditioner is not cooling at all after checking the thermostat, there could be an issue with electricity getting to the unit. In this situation, it’s a good idea to get a professional involved. Donley Service Center technicians are capable of safely tracking down electrical issues that aren’t easy to spot.

Modern air conditioners function on a complex network of wiring and programming that require the deft hand of a trained professional. They’ll be able to tell if the power is an issue with the circuit breaker, a fuse or a malfunction in the wiring of the unit itself.

Remember, there’s always a risk associated with electrical work, so make sure you talk to a certified and licensed HVAC contractor like Donley Service Center when your air conditioner is not cooling.


What do you do when the air conditioner is running, but not blowing cold air? The solution could be as easy as flipping a switch. If your AC unit is set to “on” instead of “auto” the fan will just keep blowing air, primarily room temperature air. A unit that is set to “auto” will only come on when sensors read the temperature in your home has reached a certain point, and it’s time to cool down.

You should also take a look at your air filter. A dirty or clogged filter could make the air coming out of your vents warmer than you’d want. Remove the air filter and take a look. It will be pretty easy to see if the filter needs changing. If you’re confused about how to access the air filter, or what size to use, contact Donley Service Center to get a helping hand.

If all your settings are correct and still your air conditioner is not cooling, it could be a more complex issue, but one that’s easy for a professional to take care of. Qualified professionals are experts at troubleshooting air conditioner problems.

Whether a refrigerant leak or a faulty compressor is causing your issue, it’s not something you’ll want to try to fix on your own. When you contact a licensed and insured contractor like Donley Service Center, you’ll know all the work performed on your unit is guaranteed.


An air conditioning unit is much like your car. There’s a long list of complications that can keep your unit from running. Like a car, it’s a complex piece of machinery that needs to be well-maintained and looked after to achieve optimal performance.

That’s why Donley Service Center offers customers a hassle-free maintenance program. A qualified technician can come to your home twice a year to give your unit the top-to-bottom and ensure everything is in prime working order.

This is the best way to make sure your air filter is always clean and all aspects of your system are running as efficiently as possible.
