That's Not Cool: How To Know When Your Air Conditioner Is Going To Betray You

Posted on: 19 May 2015

It's never a good experience to turn on your air conditioner on a hot day only to find it won't work properly. Your AC may give you warning signs that something is wrong with it. By paying attention to the warning signs, you can save yourself a lot of time and money by knowing when you should have an HVAC technician come out, hopefully before a small problem becomes a big one. The information below will help you recognize when trouble is brewing with your air conditioning system.

Strange smells - Anytime you notice an odd smell in your house, you need to get to the bottom of it. You need to know whether the smell is coming from the electric, the gas or even the air conditioning system.  If it's coming from the AC, it can indicate that there is a problem you want to have looked at. The smell can be coming from duct work that has damage, something inside the duct work that shouldn't be there, a motor that's starting to fail or simply a dirty air filter. The dirty air filter you can take care of yourself by cleaning it, all other problems require the help of a professional.

Noises – While it's perfectly normal to hear the AC kick on, it's not normal to hear other noises coming from it. Some examples of noises that indicate problems include squeaking sounds, humming noises, banging sounds and rattling or rumbling. Any sounds such as these can be indicative of a problem with the unit's condenser or compressor, both of which require an HVAC technician.

Inconsistency with the unit – If you notice the air conditioner popping on and off more than you feel it should, it may mean the unit is having a problem sensing the temperature. This would be due to a problem with the thermostat. Another reason your unit may do this is due to a leak somewhere.

Changes in airflow amounts – Your AC should blow with the same force it always has. As long as you know the air filter is clean and the registers are all open, then you can take a lower amount of airflow as a red flag. There may be a leak or blockage in the system or a coil may have become clogged. These problems need to be addressed before they lead to more serious issues.

Anytime you feel there may be a problem with your air conditioner, you want to call someone out to have a look at it. This way, you will keep your unit running the way it should while staying comfortable on those hot days.
