Some problems with your air conditioner can be easy to spot, while others are not so noticeable. There are some repairs that a homeowner can perform on their own, but others should be handled by a professional. As these professionals know how air conditioners work and rarely make costly mistakes, they can easily bring your home back to working condition. Here are some signs to look out for that may be cause for a call to a professional.


Your home is too hot

If you have closed all of your windows to block the sunlight and have increased airflow in your home, but the house is still hot, even with air conditioning on all day, there could still be a problem with your unit. If hot air comes out of your vents instead of cold air, call a professional to help fix the problem.


Uneven temperatures throughout your home

While the upper levels of a home can get hotter than lower levels, if the temperatures in each room vary greatly, that’s a sign something else could be wrong. If you are a homeowner and are willing to learn some of the basics, then it is fairly easy for you to change the air filters all on your own. However, the cleaning of the device and the ductwork checks, unfortunately, need to be done by a skilled professional who has the expertise and knowledge to match.


Energy bills are extraordinarily high

If your energy bill is creeping higher and higher for no apparent reason, this may indicate that your air conditioner is having to work overtime to keep your home comfortable. Cracked window or door seals, ductwork tears, and dirty air conditioning coils are all contributing factors to high energy bills. An AC professional will know what the most likely causes of your problem are and will be able to pinpoint and repair the problem.


Restricted airflow

If the airflow from your vents is weak, your house will not be cooled down. An AC professional can inspect the source of the problem, whether it is with a compressor or the ducts.


Thermostat not working

It can be very frustrating when your thermostat doesn’t work but everything else does. If the device is broken, a professional can check the wiring and calibrate the temperature readings to fix the device.


Loud noises or bad smells

Noises from your AC unit, such as grinding and scratching, are enough of a concern to contact a repair expert ASAP. The belt can be repaired along with other broken parts of the AC before extensive damage happens. Bad odours from the vents may also indicate that something has gone wrong. Regardless of whether it’s a musty odour or burnt wires, an expert’s eyes and hands are often necessary.



If you find that your unit is leaking any type of liquid, call a professional immediately. While leaks are caused by water condensation tube cracks, they also contain toxic refrigerant liquid. Always assume the worst and call a professional when your air conditioner is leaking.
