What to Do When Your Cooling System Stops Working

September 12, 2023

As a trusted HVAC contractor, the Brian's Heating & Cooling team understands that a malfunctioning air conditioning unit can be incredibly frustrating, especially during the scorching summer months here in Lexington, SC. While we always recommend reaching out to professionals for comprehensive AC repairs, there are a few steps you can take when your AC unit suddenly stops working to ensure your comfort and safety. In this blog post, we'll guide you through a step-by-step process on what to do when your AC unit stops working.


Check the Thermostat


Before you panic, start with the basics. Ensure that your thermostat is set to the cooling mode and the temperature is lower than the current room temperature. Sometimes, a simple adjustment can solve the problem.


Inspect the Circuit Breaker


Head to your electrical panel and check if the circuit breaker that controls your AC system hasn't tripped. If it has, flip it back to the "On" position. Circuit breakers can trip due to power surges or overloads.


Look at the Air Filters


A clogged or dirty air filter can impede airflow and cause your AC unit to work harder, potentially leading to overheating or a shutdown. Replace the air filter if it's dirty or clean it if it's reusable. Regularly changing or cleaning your air filter is vital for system efficiency.


Ensure Proper Airflow


Inspect the supply and return vents in your home. Make sure they're not obstructed by furniture, drapes, or other objects. Blocked vents can lead to uneven cooling and system strain.


Listen for Unusual Noises


If your AC unit is making strange or unusual noises, like grinding, squealing, or banging, it's a sign that something is amiss. Turn off the system and contact a professional HVAC technician to diagnose and address the issue.


Call a Professional HVAC Contractor


If none of the above steps resolve the issue or if you're uncomfortable performing any of these tasks, it's time to call a licensed HVAC technician. Attempting DIY repairs can lead to further damage or void warranties. Professional technicians have the expertise and tools to diagnose and fix the problem correctly.


A malfunctioning AC unit can disrupt your comfort, especially during sweltering weather. While these troubleshooting steps can help address minor issues, it's crucial to remember that your safety and the long-term health of your HVAC system are paramount. When in doubt or facing a more complex problem, always consult with a trusted HVAC contractor like us. We're here to ensure your home stays cool and comfortable year-round. Don't hesitate to reach out for professional assistance, and we'll have your AC unit back up and running in no time. Stay cool!

Preparing Your HVAC System for Spring: Essential Tips

March 13, 2025
As the weather starts to warm up, it’s the perfect time to prepare your HVAC system for the upcoming spring season. At Brian’s Heating & Cooling, we understand how crucial it is to ensure your HVAC system is running smoothly as you transition from chilly winter temperatures to the comfort of warmer spring days. Here are some essential tips to get your HVAC system ready for the season: 1. Replace Your Air Filters Dirty air filters are one of the most common causes of HVAC inefficiency. As your system works harder during the changing seasons, it’s vital to replace the air filters to improve airflow and indoor air quality. This simple task can also reduce strain on your system and help avoid costly repairs down the line. 2. Check Your Thermostat Spring means fluctuating temperatures, so make sure your thermostat is working properly. Test it by setting it a few degrees higher than your current temperature to ensure it’s maintaining a comfortable level. Consider upgrading to a smart thermostat for better energy efficiency and easier control of your home’s temperature. 3. Clean and Inspect Vents and Ductwork Dust, debris, and allergens can accumulate in your ducts over time, affecting your system’s performance. Make sure to clean all vents and inspect your ductwork for any leaks or blockages. If necessary, schedule a professional duct cleaning to ensure that air flows freely throughout your home. 4. Schedule a Professional HVAC Tune-Up Spring is the ideal time to schedule a professional HVAC tune-up. A certified technician can inspect your system for potential issues, clean key components, and perform necessary maintenance to keep your system running efficiently throughout the season. Regular tune-ups can extend the life of your HVAC system and prevent unexpected breakdowns. 5. Test Your AC System Before the hot summer months hit, it’s important to test your air conditioning system. Turn it on to ensure it’s cooling your home effectively. If you notice any strange noises, poor airflow, or insufficient cooling, call a professional to inspect and repair your AC system before the summer heat sets in. 6. Clear the Area Around Your Outdoor Unit Your outdoor unit is just as important as the one inside. Ensure that the area around your outdoor condenser unit is free of debris like leaves, dirt, and branches. Proper airflow is essential for the efficiency of the system, and clearing the area helps your system run at its best. 7. Check Insulation and Seal Leaks Proper insulation helps keep your home at a comfortable temperature without overworking your HVAC system. Check areas like windows, doors, and attics for any leaks or gaps. Sealing these cracks helps prevent energy loss and lowers your energy bills while maintaining your home’s comfort. 8. Consider Upgrading Your HVAC System If your HVAC system is aging or you’ve noticed a significant drop in performance, spring may be the perfect time to consider an upgrade. Newer models are more energy-efficient, quieter, and offer better cooling and heating capabilities, which can save you money in the long run.

Emergency Heating Tips for Lexington Homeowners

February 20, 2025
Winter in Lexington, SC, can bring unexpected cold snaps, and when your heating system fails, it can leave your home chilly and uncomfortable. Whether it’s a complete breakdown or just a minor issue, knowing what to do in an emergency can help you stay safe and warm while you wait for professional assistance. Here are some emergency heating tips for Lexington homeowners to keep in mind. 1. Check the Thermostat The first thing you should do when your heating stops working is to check the thermostat. Sometimes, it might be a simple issue like the thermostat being set to “cool” instead of “heat” or having a dead battery. Make sure the thermostat is set to your desired temperature and that it’s functioning properly. 2. Ensure Your Furnace Is Powered It’s easy to overlook the power source, but sometimes your furnace may simply be turned off at the power switch or circuit breaker. Ensure the power is on by checking the circuit breaker or fuse box. If your furnace has a switch located near the unit, make sure it is turned on. 3. Inspect the Air Filter A clogged air filter can restrict airflow, causing your furnace to overheat and shut off. Check the air filter and replace it if it appears dirty or clogged. A clean air filter will improve the performance of your heating system and can help prevent unnecessary breakdowns. 4. Keep Vents Unblocked Blocked vents can prevent warm air from circulating throughout your home. Make sure that furniture, rugs, or drapes are not covering the vents or registers. For optimal airflow, you should also ensure that the return vents are clear of any obstacles. 5. Check for Pilot Light Issues If you have a gas furnace, check the pilot light to see if it has gone out. If it has, you can follow the manufacturer's instructions to safely relight it. If you’re unsure or uncomfortable doing this, call a professional HVAC technician to handle the issue. 6. Listen for Unusual Sounds If you hear strange noises, such as banging or grinding, it could indicate a mechanical issue with your heating system. While this isn’t something you can fix yourself in an emergency, being aware of it can help a technician quickly diagnose the problem when they arrive. 7. Don’t Attempt DIY Repairs While some minor maintenance tasks are easy to handle, if your heating system is malfunctioning, avoid attempting major repairs on your own. Incorrect repairs can worsen the problem or even cause safety hazards, especially with gas furnaces. Always call a licensed HVAC professional like Brian's Heating & Cooling for emergency repairs. 8. Keep Warm Until Help Arrives If your heating system goes out and you need to wait for a technician, keep warm by layering your clothing and using blankets. If necessary, use a space heater as a temporary solution, but never leave it running unattended and keep it away from flammable objects. 9. Schedule Regular Maintenance One of the best ways to prevent heating emergencies is to schedule regular maintenance for your system. Brian's Heating & Cooling offers comprehensive tune-ups that can help identify potential issues before they turn into emergencies.
