Ask This When Troubleshooting A Broken Air Conditioner

With summer temperatures already on the rise, for those that are fortunate enough to have home air conditioning, the thought of it breaking down can bring feelings of helplessness and anxiety. Imagine setting the thermostat to a comfortable 70 degrees, setting the system dial to ‘auto’, patiently waiting to hear the fan kick on, only to hear – nothing. The temperature inside your home begins to rise and yet, the cooling mechanism still hasn’t kicked in. What do you do? Opening a window and turning on a few fans might be a good start but if you’re feeling up to the challenge of diagnosing your air conditioning problems, here’s a little help to get you started.

    Is It Receiving Power?

    If you’re lucky, it could be just as simple as a tripped circuit breaker. Locate your electrical panel and see if any of the switches have flipped. Make sure to use extra caution when dealing with any sort of home electrical problem as 110-220 volts can be extremely dangerous. If you aren’t sure where to look or what to do, it might be time to call an electrician or an HVAC repair specialist.

    Does the Fan Run?

    Most HVAC systems consist of a fan that will blow the cooled air out through your vents. If you flip the switch to ‘fan on’ and you can feel and hear air moving through the system, you can probably rule out that the fan is the issue. If the fan does not run, you could either have an electrical problem or your fan might be broken.

    What is the thermostat set to?

    It might sound silly but check to make sure the thermostat is set to a temperature a few degrees below your home’s internal temperature. It’s not at all uncommon for someone to inadvertently move the thermostat to a warmer temperature and thus, the system doesn’t turn on. If you set the thermostat to say, 65 degrees, and your house’s internal temperature is 80 degrees, you might have an issue with your thermostat.

    Is there anything else I should look for?

    If you’ve checked your systems power, fan, and thermostat settings and all of them appear to be normal, you could have an issue deeper inside the system. At this point, it’s probably time to call an HVAC repair specialist to take a look. Make sure to find out the costs of diagnosing a broken system before they begin doing any work. You don’t want to get stuck with unexpected service charges.
