What to Do When Your AC Stops Working: A Quick Guide

There’s nothing worse than having your air conditioning system fail in the middle of a heatwave. If you find yourself in this unfortunate situation, don’t panic. Here’s a quick guide on what to do when your AC stops working to get you back to comfort as soon as possible.

Step 1: Check the Thermostat
Before you assume the worst, check your thermostat settings. Ensure it's set to “cool” and the temperature is lower than the current room temperature. Sometimes, a simple setting adjustment or battery replacement is all that’s needed.

Step 2: Inspect the Circuit Breakers
An AC unit can trip the circuit breaker, especially during high usage. Locate your home’s circuit panel and check if the breaker for the AC has tripped. If so, reset it and see if that solves the problem. If it trips the breaker more than once, it’s time to call a professional for an AC repair.

Step 3: Examine the Air Filters
Clogged air filters can severely hamper your AC’s performance. If you haven’t changed the filter in a while, now’s the time to check. Replace it if it's dirty to improve airflow.

Step 4: Check the Vents
Make sure all vents in your home are open and unobstructed. Sometimes furniture or curtains can block vents, causing poor airflow and system inefficiency. Vents in an AC system are designed to be left open, even in rooms that are not used.

Step 5: Look for Ice Build-up
If your AC unit has ice on the evaporator or condenser coils, this can halt its function. Turn off the AC and let the ice melt. If the problem persists, consult an HVAC repair professional.

Step 6: Investigate Odd Noises
Any strange sounds like clicking, buzzing, or grinding are signs of a problem that likely requires professional attention. Turn off the system to prevent further damage and call a technician.

Step 7: Assess Drainage Issues
A clogged drain line can lead to water leaks and system inefficiency. Try clearing the drain line yourself, or call in a professional if you’re unsure.

Step 8: Call a Professional
If none of the above steps resolve the issue, it’s time to consult an expert. Look for a qualified and reputable HVAC service provider to diagnose and fix the issue.

Step 9: Consider a Temporary Solution
While waiting for professional help, consider using fans or portable air conditioners to keep cool. Keep blinds and curtains closed to block out heat and stay hydrated.

Step 10: Plan for the Future
Once your AC is up and running again, take steps to prevent future breakdowns. Schedule regular maintenance checks and heed the advice of your HVAC technician on any upgrades or replacements.

Conclusion
When your AC stops working, it's a stressful experience, but quick action can mitigate the discomfort. By following these steps, you'll be better prepared to diagnose the issue, potentially fix minor problems yourself, and know when it's time to call a professional.
Remember, preventive maintenance is key to avoiding such issues in the first place. So once you're back to enjoying a cool, comfortable home, consider scheduling regular HVAC check-ups to keep things running smoothly.
