what do do if your ac fails

An air conditioning system failure during the sweltering summer months can quickly turn your home into an uncomfortable space. Knowing what to do in this situation can save you time, stress, and possibly money on AC repair. Here’s a comprehensive guide to help you navigate what to do if Your AC fails.

1. Check the Thermostat Settings

Before panicking, ensure your thermostat is set correctly. Make sure it’s on the “cool” setting and the temperature is set lower than the current room temperature. Also, check if the thermostat has power; sometimes, it may need new batteries or a simple reset.

2. Inspect the Circuit Breaker

Your AC unit might have stopped working due to a tripped circuit breaker. Locate your home’s electrical panel and check if the breaker corresponding to your AC is in the “off” position. If it is, switch it back to “on.” If it trips again, this could indicate a deeper electrical issue that needs professional attention for AC repair.

3. Examine the Air Filter

A clogged or dirty air filter can cause your AC to malfunction. Check the filter and replace it if it’s dirty. Regularly changing air filters and scheduling routine air conditioning maintenance can prevent such issues and improve your AC’s efficiency.

4. Look for Obvious Issues

Sometimes, the problem can be easily spotted. Check if there are any visible issues like disconnected wires, water leaks around the indoor unit, or debris blocking the outdoor unit. Clearing debris and ensuring proper drainage can sometimes resolve minor issues.

5. Give It Some Time

If your AC unit has been running non-stop, it might need a break. Turn off the system for 30 minutes to an hour and then restart it. This simple step can sometimes reset the system and fix minor glitches.

6. Check the Condensate Drain

Air conditioners have a condensate drain that can get clogged with algae or debris. A clogged drain can cause water to back up and potentially shut down the system. If you notice standing water, contact us for drain line cleaning.

7. Ensure Proper Ventilation

Make sure that all air vents and registers are open and not blocked by furniture, drapes, or other objects. Proper airflow is crucial for your AC system to function effectively.

8. Call a Professional

If none of the above steps resolve the issue, it’s time to contact LA Construction, Heating and Air. Trying to fix complex issues on your own can lead to further damage and safety risks. One of our professional technicians will diagnose the problem accurately and perform necessary air conditioning repairs or HVAC replacements.

Preventive Measures

To avoid future AC failures, consider these preventive measures:

Regular Maintenance: Schedule annual or bi-annual maintenance checks with a professional HVAC technician.

Change Filters Regularly: Replace air filters every 1-3 months, depending on usage and filter type.

Monitor Thermostat Settings: Use programmable thermostats to optimize cooling and reduce strain on the system.

Seal Leaks: Ensure your home is well-insulated and free from air leaks to maintain consistent indoor temperatures.
