Types of A/C Cooling Problems:

  • Blowing warm air instead of cold?

There could be a few reasons why your air conditioning unit is blowing warm air instead of cold. One possibility is that the filter needs to be replaced. Inspect the air filter for a possible dirty A/C filter. If the filter is clogged, it will prevent the cold air from flowing through the unit properly. Another possibility is that there may be something blocking the airflow in your home, such as furniture or curtains.

  • No cold air coming out at all?

Unfortunately, there is nothing that you can do until you call an A/C technician out to look at it. It sounds like the compressor may be broken or the air handler has possibly failed.



  • A/C making loud or unusual sounds?

Buzz sounds, warbling, or other high/low frequency noises while your A/C unit is in operation are not a good sign. Don’t panic, just call for maintenance as soon as you can. Avoid unnecessary repairs by getting us out right away. Replacing a unit that could have been saved 24 hours is a hard pill to swallow as a home owner.

  • System seems to be running constantly, but your home is still not getting cool?

The a/c unit is working hard to keep your home cool, and it is using more energy than usual because of the extreme heat. Most A/C units have a 20-22 degree differential that it can provide adequate cooling for. Meaning that when its 98 outside, your inside thermostat is should be set lower than 76-78 degrees. If not, then your system will have to work a lot harder (and longer) to keep up with your demands. The electric bill will go up as a result to unreasonable cooling demands as well. 

In the meantime, you should try to conserve energy by turning off lights when we are not using them and shutting off appliances when they are not in use. If you are in doubt of whether your A/C unit is functioning properly, call the Rick Rasch team to investigate and get a report.
