Don’t Try to Fix It Yourself

Tinkering with your AC unit is not a DIY project and best left to the HVAC experts. The heat & cooling service maintenance experts at AtlasCare can troubleshoot your air conditioner to get it up and running smoothly again in no time.

The internet is full of DIY tips and how-to videos for the homeowner. It can easily lead you to believe that you can diagnose and repair your AC unit yourself. But unless you have experience with mechanical repairs, troubleshooting your unit is best left to a trained HVAC technician. Not only can they diagnose the problem in half the time, but they can also quickly source any replacement parts.

Don’t Look for Replacement Parts Yourself

Don’t go searching for replacement parts yourself. Cheaper products on the internet may be inferior to your equipment. AtlasCare sources products from reputable companies and combine that with their expert training so that they’re installed properly and guaranteed to last.

Don’t Overlook the Obvious

Be sure to check your thermostat to make sure the program settings for you AC unit are correct. Sometimes little hands, or even not so little hands make unwanted changes. The thermostat should be set to cool, and left on AUTO. It’s also a good idea to check the thermostat battery.

It’s also possible that a circuit breaker has tripped. Check to see that your circuit breaker is not in the off position. If so, flip it on and see if your unit restarts.

A clogged air filter will prevent any airflow. Clean or replace your air filter to see if that remedies the problem. Clean your filter with a soft brush, mild soap and water. Change and clean your filter often to avoid this problem in the future.

Don’t Switch Your A/C Unit On and Off Repeatedly

When your system is running as it should it automatically cycles on and off according to the temperature changes. Turning your AC unit on and off quickly and unnecessarily causes excess stress and wear and tear on your system.

If cleaning or replacing the filter does not resolve the problem, there may be any number of other problems to diagnose with simple solutions, to more serious situations where your AC unit will need to be replaced.
