Why Your AC Is Blowing Warm Air in Pleasant Prairie, WI

Struggling through a hot day and getting a blast of warm air from your AC is an awful feeling. Not only are you sweating buckets, you start to worry your system might be damaged or breaking down.

We’re happy to say an AC blowing warm air in Pleasant Prairie, WI, isn’t usually cause for alarm. There are many simple reasons why this issue could be happening, so our guide will help you with a little process of elimination. If none of our DIY fixes work, we’ll also explore the more serious reasons and when it’s time to reach out to a professional service.

4 Minor Reasons Why Your AC Is Blowing Warm Air

If your AC isn’t cooling in Wisconsin, see if one of these four reasons is why. You can do these quick fixes right in the comfort of your home to get cool again.

1. Your Filters Are Too Dirty

Your filters maintain regular airflow so your system can distribute cool air throughout your home. It also does double duty, trapping indoor contaminants like dust, dander, pollen, and dirt. 

If you haven’t changed your filters in a few months (or longer), you very likely have the solution right in front of you. Change out your filter and see if that fixes the problem. Make sure to only use filters approved for your cooling system, as incompatible filters can cause problems like higher energy bills or even more warm air.

2. Your Cooling Setting Is Off

Are your filters fine? Check whether your cooling setting is off instead. Most heating and cooling issues in Pleasant Prairie can boil down to a little accidental neglect. 

Your system should have a ‘cool’ or ‘on’ setting. If it’s set to ‘off’ or ‘warm’, flip it and run your system for a few minutes. Keep in mind that large homes take longer to cool down than smaller houses. A humid day can also take longer to cool down since airborne moisture traps heat.

3. Your Thermostat May Be Miscalibrated

Is your thermostat set to the right setting? Don’t write it off just yet. An AC blowing warm air in Pleasant Prairie sometimes stems from a thermostat that’s not reading temperatures well.

A simple way of testing your thermostat is to get a second one and place it in the room. You can compare the two after a few minutes to see if you’re getting different readings. A difference of one or two degrees is perfectly normal, but a drastic gap could mean your AC’s thermostat is dying.

You can also try calibrating your thermostat by changing the temperature manually. Try lowering it a few degrees and see if that triggers your system into blowing cool air again.

4. You Have a Circuit Breaker Issue

An AC not cooling in Wisconsin can stem from a circuit breaker that was turned off or tripped. Did you recently have a technician visit your home for some routine repairs? They may have forgotten to flip your breaker back on before leaving.

Your circuit breaker can also trip from a storm to protect you from an electrical hazard. As long as you don’t suspect any physical damage, you can reset a circuit breaker by turning the appropriate switch off. After a few minutes, turn it back on and see if that restores power.

If your circuit breaker trips again after you try to reset it, you likely have a deeper problem like a faulty wire or damaged fixture. You’ll need to contact a technician or electrician to take a look.

A damaged circuit breaker is just one of the more serious issues that could be impacting your cooling system. You could be getting warm air for reasons like electrical issues or old age.

4 Major Reasons Why Your AC Is Blowing Warm Air

Sadly, sometimes the reasons why your AC is blowing warm air in Pleasant Prairie are more serious. If none of the above fixes work, you likely have a bigger problem that requires a maintenance or repair visit. 

1. Your Refrigerant Levels Are Low

Sometimes your system runs out of refrigerant before it’s supposed to. This important chemical is crucial for changing warm air to cool air, so a blast of warm air could be a sign that you need to have your refrigerant levels checked by a trained technician. 

2. Your Condenser Coils Are Clogged

An AC blowing warm air in Pleasant Prairie, WI, often comes from the condenser coils, a vital component of absorbing and releasing warm air outside. The connected drain pipe could have a mold or mildew problem from too much trapped moisture, a common problem due to the state’s humidity levels. 

This moisture can result in a clog that blows warm air right back in. A technician can open up your system and do a little cleaning to get your coils working like new. They’ll flush out any gunk that may have gathered over time, then test to see if that fixes the issue. 

3. You Have an Electrical Problem

If you don’t suspect dirty coils or low refrigerant, you might have an electrical problem sucking away power from your system. If your AC doesn’t have a steady supply of electricity to turn on and run, it can blow warm air (or short-cycle, which means it turns off too soon).

Experienced technicians can take a look at your wiring for signs of damage like twisted or melted cords. 

4. Your Unit Is Eight Years Old (or Older)

Even the best cooling system will start to struggle after a point. Parts get worn out, refrigerant levels get low, and energy-efficiency ratings start getting outdated.

If your AC is blowing warm air in Pleasant Prairie because it’s too old, there isn’t much you can do at that point. You should consider a new cooling installation after eight years, though routine maintenance may extend your system’s lifespan another two or three. 

Sometimes trying to repair an old system can backfire on you in the long term. However, your AC might still be young enough to bounce back with a routine visit. No matter what you need, we have the tools and expertise to get the job done.
