Northern Virginia is currently grappling with one of the most intense heatwaves in recent history. With temperatures frequently exceeding 90°F and humidity levels soaring, ensuring your air conditioning system is functioning optimally is not just a matter of comfort but also of safety. HVAC & Plumbing Unlimited is dedicated to helping you navigate through such challenging times by offering reliable and swift emergency HVAC services. This comprehensive guide will provide you with essential steps to take when your AC system breaks down during extreme heat, ensuring your safety and comfort until professional help arrives.

Step 1: Assess the Situation

The first thing to do when your AC stops working is to assess the situation. This involves a quick inspection to determine whether the issue might be something you can resolve yourself or if you need to call in professionals.

First, identify the problem: Conduct a basic inspection of your AC unit.

Thermostat Settings: Ensure that your thermostat is set to “cool” and the temperature is set correctly. Incorrect settings can sometimes be the simplest fix.

Obvious Signs of Trouble:

Unusual Noises: Grinding, squealing, or banging sounds can indicate mechanical problems such as a loose belt or failing motor.
Leaks: Water pooling around the unit may signal a blocked or broken drain line. Leaks can also suggest refrigerant issues, which require professional attention.Lack of Airflow: Weak or no airflow could mean a blocked duct or a failing compressor, often caused by a clogged air filter or issues within the ductwork.
Warm Air: If the air coming from the vents is warm, there might be a refrigerant issue or a failing compressor, indicating a need for professional service.

Next, turn off the unit: If the AC is making unusual noises or showing signs of damage, turn it off to prevent further damage. Operating a malfunctioning AC unit can cause more extensive damage and increase repair costs.

Step 2: Ensure Your Safety

Safety is paramount when dealing with an AC breakdown, especially during a heatwave. Here are some steps to ensure you and your family stay safe:

Check for electrical issues: Verify there are no electrical hazards around the unit.

Tripped Circuit Breakers or Blown Fuses: Check your electrical panel for any tripped breakers or blown fuses. Reset or replace them as necessary. Electrical issues are a common cause of AC breakdowns and can sometimes be easily fixed.
Avoid Water: If there’s water around the unit, avoid touching it to prevent electrical shock. Water and electricity are a dangerous combination.

Next, move to a cooler area: If the indoor temperature rises quickly, relocate to a cooler part of the house or seek temporary shelter elsewhere. This is especially important for vulnerable individuals such as children, the elderly, and pets.

Step 3: Troubleshoot Common Issues

Before calling for professional help, try troubleshooting some common AC issues. Simple fixes might get your AC working again.

Thermostat Check:

Confirm that the thermostat is set to “cool” and the temperature is correct. If the thermostat is not functioning properly, it can cause the AC to malfunction.

Programmable Thermostats: If you have a programmable thermostat, make sure the schedule is set correctly and the batteries are working.

Air Filter:

Check and replace a dirty air filter, which can cause the unit to stop working. A clogged air filter restricts airflow and can cause the AC to overheat and shut down.

Filter Types: Understand the type of filter your system uses and ensure it is replaced regularly. High-efficiency filters, while better at removing particles, may need to be changed more frequently.

Circuit Breaker:

Reset any tripped circuit breakers. If the AC unit is drawing too much power, it might trip the breaker.

Electrical Panel: Familiarize yourself with the location of your electrical panel and the specific breaker for your AC unit.

Outdoor Unit:

Ensure the outdoor unit is free from debris and has proper airflow.

Clean the Coils: If accessible, gently clean the outdoor unit’s coils to remove dust and debris. Dirty coils can reduce the efficiency of your AC and cause it to overheat.
Clear Vegetation: Trim back any plants or shrubs obstructing airflow around the unit. Proper airflow is crucial for the outdoor unit to function correctly.

Step 4: Call for Professional Help

If troubleshooting does not resolve the issue, it’s time to call in the professionals. HVAC & Plumbing Unlimited offers 24/7 emergency services to assist you when needed.

What to Communicate: When you call, be prepared to describe the problem in detail.

Prepare for the Technician’s Visit: Clear the area around the AC unit and have any necessary information ready, such as previous maintenance records. This will make it easier for the technician to access and repair the unit.

Detailed Notes: Keep a log of any unusual symptoms or behavior your AC unit has displayed. This can help the technician identify the problem more efficiently.
Maintenance Records: If you have any previous maintenance records, have them ready for the technician. This can provide valuable context and history about your AC unit, helping to identify the problem faster.

Step 5: Implement Temporary Cooling Solutions

While waiting for professional help, keeping yourself and your family cool is crucial. Here are some temporary cooling solutions:

Use Fans: Set up fans to circulate air and create a cooling breeze. Ceiling fans and portable fans can help move air around and make the room feel cooler.

Placement: Position fans in windows to draw in cooler air during the evening and night. Use ceiling fans to enhance the cooling effect of your AC when it’s running.

Close Blinds and Curtains: Block out sunlight to reduce indoor heat gain. Keeping the sun out can significantly lower the indoor temperature.

Reflective Blinds: Use reflective blinds or curtains to deflect sunlight and heat away from your home.

Stay Hydrated: Drink plenty of water and avoid strenuous activities. Staying hydrated is essential to prevent heat-related illnesses.

Hydration Tips: Keep a water bottle with you and sip water throughout the day. Avoid caffeinated or alcoholic beverages that can dehydrate you.

Cool Showers and Compresses: Take cool showers and use cold compresses to help lower body temperature. This can provide immediate relief from the heat.

Pulse Points: Apply cool compresses to pulse points such as wrists, neck, and temples for quicker cooling.

Ice Packs and Wet Towels: Place ice packs or wet towels on pulse points (wrists, neck, and temples) to help cool down. These areas are where blood vessels are close to the skin, so cooling them can help lower your overall body temperature.

DIY Cooling Packs: Make your own cooling packs by freezing water bottles or wet washcloths.

Create a Cool Room: Designate a room in the house to keep as cool as possible by using fans and closing it off from the rest of the house. This can be a refuge from the heat until your AC is fixed.

Room Setup: Choose a room on the lower level, as heat rises. Close doors and use heavy curtains or blankets to insulate the room.

Step 6: Prevent Future Breakdowns

To avoid future AC breakdowns, regular maintenance and proactive measures are essential.

Regular Maintenance: Schedule regular AC maintenance checks with HVAC & Plumbing Unlimited to keep your system in good condition. Regular maintenance can catch minor issues before they become major problems.

Seasonal Checks: Schedule maintenance checks in the spring and fall to ensure your system is ready for the extreme temperatures of summer and winter.

Replace Air Filters: Change air filters regularly to ensure proper airflow and efficiency. A clean air filter can improve the performance and lifespan of your AC unit.

Filter Schedule: Follow the manufacturer’s recommendations for filter replacement, typically every 1-3 months.

Monitor System Performance: Keep an eye on your system’s performance and address any minor issues before they become major problems. If you notice anything unusual, don’t wait to get it checked out.

Energy Bills: Monitor your energy bills for any unexpected increases, which could indicate your system is working harder than it should.

Health Concerns During a Heatwave

Extreme heat can pose serious health risks, especially if your AC breaks down. It’s essential to be aware of these risks and take steps to protect yourself and your family.

Heat Exhaustion and Heatstroke:

Prolonged exposure to high temperatures can lead to serious health issues.

Symptoms of Heat Exhaustion: Heavy sweating, weakness, cold or clammy skin, fainting, and nausea. If you or someone else shows these symptoms, move to a cooler place, drink water, and rest.
Symptoms of Heatstroke: High body temperature (above 103°F), hot and dry skin, rapid pulse, confusion, and unconsciousness. Heatstroke is a medical emergency. Call 911 immediately if you suspect someone is experiencing heatstroke.

Hydration: Staying hydrated is crucial to prevent heat-related illnesses. Ensure you drink water regularly, even if you don’t feel thirsty, as dehydration can set in quickly during extreme heat.

Indoor Temperature Management:

During a heatwave, indoor temperatures can rise significantly, especially if your AC is not working. The National Weather Service provides guidelines to help monitor and manage indoor temperatures.

Optimal Indoor Temperature: Aim to keep indoor temperatures below 85°F to avoid health risks. Use fans, cool showers, and other methods to maintain a safe and comfortable environment.

Monitoring Temperature: Use indoor thermometers to monitor the temperature in various parts of your home. If the temperature starts to climb above safe levels, take immediate steps to cool down.
Humidity Control: High humidity can make the heat feel more oppressive. Use dehumidifiers to help reduce indoor humidity levels, making it easier to stay cool.
