Noticing your AC blowing warm air? Now that’s a reason to sweat. Dont panic. There are many different reasons why your AC is blowing warm air and sure, it can get kind of complicated.
But hold the phone. Before calling a professional, check out these 3 common causes that are simple to diagnose and easy to fix on your own.
Thermostat set to HEAT or fan set to ON: Yes, we’re serious. Check your thermostat setting and make sure it’s NOT set to “HEAT”. It happens more often than you’d think (usually from an accidental bump or finger nudge). “ON” means the fan is always blowing air through your vents, even when your system isn’t working to cool the air it blows. And, while that can help improve air quality if you have a whole-home air cleaner installed, it could also be the reason why you feel warm air (or at least air that isn’t cooled) blowing through your vents.
DIY fix: Make sure your thermostat is set to “COOL”. And use the “AUTO” setting if you don’t have a whole-home air cleaner.
Outside unit clogged: Your home’s AC system is made up of 2 main components— an outside unit and an inside unit. Both units work together to remove heat from your home. To do that, it needs unrestricted airflow to something called a “condenser coil”, which is located in your outside unit.
An outside unit clogged by dirt, leaves or debris can keep your AC from properly cooling your home’s air.
DIY fix: You can prevent this problem by using a broom to sweep any visible debris away from your outside unit. Also make sure to trim bushes, weeds and tall grass that could restrict airflow.
Loss of power to outside unit: As we discussed earlier, your AC system is actually 2 parts that work together. If the outside unit loses power but the inside unit doesn’t, it is possible that you could experience warm air coming out of your air vents.
There are 2 places an outside AC unit can lose power:
- At the circuit breaker. Check to see if the breaker for your outside unit got tripped.
- An emergency shutoff switch. This is usually located on your home’s exterior wall, right by the outside AC unit. Check to see it’s in the “on” position.
DIY fix: Locate the breaker switch on your outside unit and flip the switch all the way OFF and then back ON.

During the peak times of the summer months, a good air-conditioning system in your home or office provides a nice, cool air flow, and optimum comfort to escape the temperatures of extreme heat. But even the best and most high tech A/C units can still develop minor snags, causing them to either fail, or prevent them from working efficiently after a period of time. This is why it’s so essential to get your A/C system serviced well ahead of time, before any repairs are ever needed. However, in the case where repairs are necessary, here are our top 5 repair tips that you should take into consideration before any existing problems escalate into much bigger issues in the future.
Warm or Stale Air
This is actually quite a common problem which typically occurs when the evaporator coils have become frozen. The air in your home will eventually turn warm, or seem stale. You can attempt to repair it yourself by thawing out the entire system, although contacting a professional to assist with repairs may be a better option. This is because sometimes there may be other underlying issues that they can diagnose in which you might be unable to see.
Foul Smell or Odor
If you are getting an odd or downright foul smelling odor that omits from the A/C unit after switching it on, then there’s a chance that there is a potential obstruction in the duct system somewhere. Generally, it is caused by an abundance of bacterial or mildew growth within the system or unit. Thoroughly cleaning up any constricted ducts will allow for more efficient breathing of the system, helping you to prevent or avoid any respiratory problems that could arise as a result.
If you find that your air conditioner is just simply not able to perform or function in the way that it is supposed to, then you can also check its circuits. In some cases, you may even find the AC unit is unable to get powered back on, at all. Check the breakers to find out if one has been thrown, or if it has possibly even blown up.
A healthy running A/C system will typically make a continuous low humming or whirring sound, which is generally not given too much attention. However, squealing or squeaking noises are normally not a good sign, and they are often related to belt problems. Also, rattling noises are generally a result of one or more operating components that have come loose. Changes in sounds are usually ignored, but doing so for too long can result in much bigger problems down the road. You should get any unusual or odd noises checked out by professional servicemen as soon as possible.
If you experience any abnormal changes in your internal temperatures without making any adjustments to the settings, then the thermostat might need to either be repaired, or possibly even replaced. In many cases, simply calibrating the thermostat can take care of the problem, and get your A/C unit back to functioning properly again. Either way, it is a good idea to hire a professional in this instance, rather than fix the problem on your own.
