Things to Check Before Calling for AC Repair

March 27, 2025

When your AC isn't working as it should, frustration can quickly set in. Before you call for professional assistance, there are simple checks you can do yourself. Often, these quick fixes can solve the problem and save you both time and money.


Sometimes, an air conditioner issue might not be what it seems. Thermostat settings, dirty filters, and tripped circuit breakers might be the real culprits. Understanding these common problems and their easy solutions can often restore your cool comfort without a repair bill.


Learning how to troubleshoot your AC can give you peace of mind and keep your home comfortable. It's all about knowing where to look and what to do. You might find that a simple adjustment or cleaning is all you need to stay chill this season.


Check the Thermostat Settings


Thermostats often cause confusion when they mimic AC problems, yet the issue might just be a simple setting error. A minor adjustment can sometimes solve what seems to be a malfunction. A thermostat set to the wrong mode or temperature can result in an inefficient cooling system.


Follow these steps to check and adjust your thermostat settings:


1. Verify the mode: Make sure the thermostat is set to "Cool" instead of "Heat" or "Off."

2. Set the temperature: Adjust the temperature setting to a few degrees lower than the current room temperature to see if the AC kicks on.

3. Check the display for errors: Look for error messages or alerts that could indicate a faulty thermostat or sensor issue.

4. Replace batteries: Ensure the thermostat has power by checking or replacing the batteries if it's a battery-operated model.


Keeping fresh batteries in your thermostat helps avoid unexpected power loss. A powered and correctly set thermostat ensures your AC can efficiently cool your home. Simple thermostat checks often clear up confusion, making your system work better without further issues.


Inspect the Air Filters


Dirty air filters can make your AC struggle to cool your home effectively, as they restrict airflow and reduce system efficiency. A clogged filter can lead to higher energy bills and even system malfunctions if left unchanged.


Here's how to assess and replace air filters:


1. Locate the filter: Find your system’s air filter, typically located behind a cover on the return air duct.

2. Examine the filter: Hold it up to light; if you can't see the other side, it's time for a change.

3. Choose the right filter: Find a replacement filter that matches the size and type recommended for your system.

4. Install the new filter: Insert the new filter according to the airflow indicator arrows on the frame.


Watch for these signs indicating it's time for a new filter:


  • Increased dust around your home
  • Higher electricity bills without increased usage
  • Unusual noises or poor air flow from vents


Replacing air filters regularly keeps your AC unit running smoothly, enhances indoor air quality, and promotes a longer system life. Paying attention to your filters is a simple yet effective way to ensure efficient cooling throughout your home.


Examine Circuit Breakers and Power Supply


Tripped circuit breakers are a frequent culprit when the AC suddenly stops working. A breaker might trip due to a one-time power surge or excessive demand on the electrical circuit. Restoring power often requires just a simple reset.


Follow these steps to safely check and reset circuit breakers:


1. Locate your electrical panel: Find the main electrical panel, usually in a garage, basement, or utility room.

2. Open the panel: Carefully open the panel door to reveal the switches.

3. Identify tripped breakers: Look for any switches that are out of alignment. A tripped breaker often rests midway between the "on" and "off" positions.

4. Reset the breaker: Push the breaker fully to the "off" position, then switch it back to "on."


Before calling for repairs, consider other power supply issues such as:


  • Loose electrical connections: Inspect any visible wiring for signs of wear or looseness, though this should often be left to professionals.
  • Fuse issues: Some systems might have fuses that require replacement if blown.


Ensuring that the power supply to your AC is functioning helps keep the system running and can prevent unnecessary service calls. Regularly checking your circuit breakers and understanding basic power supply checks save time and hassle when troubleshooting AC issues.


Look for Blocked Air Vents


Blocked air vents can heavily affect the cooling efficiency of your AC system by preventing proper airflow. When vents are obstructed, it forces your AC to work harder, reducing its lifespan and increasing energy costs.


To inspect and clear vents in your home, follow these tips:


  • Walk through each room: Check vents and registers for any visible blockages like furniture, curtains, or toys.
  • Remove obstructions: Clear away any items that might cover or close off vents to ensure air can circulate freely.
  • Adjust vent louvers: Make sure vents are open and angled appropriately to direct cool air into your living spaces.


For proper airflow throughout your home:


  • Keep vents clean: Remove dust and debris from vent covers using a vacuum or a damp cloth.
  • Balance airflow: Consider partially closing vents in less-used rooms to direct more air to frequently occupied spaces.


Maintaining clear air vents promotes efficient cooling and comfort across your home. By regularly checking and cleaning your vents, you enhance your AC's performance and boost its ability to keep your living spaces pleasant.


Conclusion


Taking proactive steps to maintain your AC system prepares it to efficiently handle heat and keep your home comfortable. Regularly checking your thermostat settings, air filters, circuit breakers, and air vents plays a crucial role in ensuring optimal performance. These tasks are simple yet impactful, leading to fewer repairs, lower energy bills, and improved system reliability.


A well-maintained AC system not only enhances comfort but also extends the life of your equipment. By implementing these tips, you put yourself in the best position to enjoy a trouble-free cooling season. The peace of mind that comes with a functioning, efficient AC system means more worry-free time to enjoy the things you love.

Modern HVAC systems have become a staple in homes, offering a blend of efficiency and comfort that older models simply can't match. These systems are designed not just to regulate temperature but to enhance overall residential comfort. They quietly work in the background, ensuring a steady flow of clean air while keeping indoor climates just right. Residents in Owensboro, KY, particularly appreciate how these systems adapt to the local climate, balancing energy use with the demands of the seasons. Upgrading to a modern HVAC system has a number of environmental perks. From energy efficiency to improved air quality, these systems are tailored to be kinder to our planet while offering superior performance. As concerns over environmental impacts grow, it's increasingly clear that these advancements aren't just nice-to-haves—they're pivotal for sustainable living. Owensboro homes, with their distinct weather patterns, stand as testament to how modern HVAC systems can seamlessly integrate sustainable practices into everyday life.
