You may set the thermostat to the desired temperature only to end up with hot air blowing out of the ducts. This can be caused by dirty air filters or a faulty thermostat. It can also occur due to debris piling up around the outdoor condenser, so you may need to clear out your yard if this is the case.


When the AC does not work at all, you should check your thermostat’s batteries. You should replace them if they are dead. If that does not work, then check the circuit breaker to see if it has been tripped. If neither of these scenarios are the problem, you should call the team here at Buddy’s A-1 Air Conditioning & Heating for 24/7 service. We can diagnose the problem with your air conditioner and get it running again—fast.


Squealing or screeching noises can come from a faulty blower motor. When this is the case, call Buddy’s A-1. Our technicians probably need to apply lubricant to the oil port. However, while we’re doing this, we’ll also check for other components that have come loose throughout the system. Loose parts can lead to strange noises from the air conditioner.


A leak can form anywhere in your AC unit. Leaks most often form due to clogs. You will need to unclog the system, so air flows effortlessly throughout the system. You should also take a look to see if you have frozen coils that could be obstructing something. Frozen coils are caused by poor return airflow—turn your air conditioner off and call Buddy’s A-1 for help thawing out the coils and fixing the root cause of the problem.


Uneven cooling is often a result of blocked vents or poor insulation. A heat imbalance in your home can also be the result of one room getting more sunlight than the others. As the air conditioner tries to cool down that hotter room, it freezes the others in the home. Try taking steps to keep that room from getting too hot, such as adding blinds or shades to block sunlight.
