When the scorching summer heat arrives, the last thing you want is for your trusty HVAC system to blow warm air or fail altogether. Fear not! As service providers for San Antonio through Kyle, Shafer Services Plus has you covered with a range of solutions to help you stay cool and comfortable throughout the summer season.

In this blog post, we will explore solutions by putting together a guide that ensures your HVAC unit remains in optimal condition, preventing the need for cooling repairs and avoiding central air repair costs.

1. Double Check Your Circuit Breaker: The First Line of Defense

Let’s start with the basics – anything that’s an easy fix! Sometimes the reason for your HVAC unit not functioning properly can be as simple as a tripped circuit breaker. Before panicking or calling for professional assistance, take a moment to inspect your circuit breaker. Ensure that the circuit supporting your HVAC unit hasn’t been turned off accidentally. By taking this one simple step, you can potentially save yourself from incurring unnecessary expenses for an HVAC diagnostic call, A/C check, or cooling check. It’s always worth double-checking before proceeding to other troubleshooting measures.

To avoid any confusion, locate your circuit breaker panel, which is typically found in the basement, utility room, or garage. Open the panel and scan for any breakers that are in the “off” position or positioned between “off” and “on.” If you find a tripped breaker, simply flip it back to the “on” position. Remember, if the same breaker trips repeatedly, it may indicate an underlying issue that requires professional attention. In such cases, it’s best to reach out to a qualified A/C technician or cooling technician to diagnose and resolve the problem.

2. Make Sure Your Thermostat Is Working: Don’t Let It Fool You

Your thermostat plays a crucial role in maintaining the desired temperature in your home. However, it can often be overlooked when troubleshooting HVAC issues. Take a moment to inspect your thermostat and ensure it is set correctly for cooling. Sometimes, someone may have accidentally switched it to heat mode, resulting in warm air blowing through your vents. Additionally, consider the location of your thermostat. Is it exposed to direct sunlight or placed near a heat source? Such factors can impact its accuracy and effectiveness. Finally, test the thermostat by adjusting the temperature settings and monitoring how your HVAC unit responds. If you notice any inconsistencies or irregularities, it may be necessary to consult an HVAC professional to assess and rectify the issue.

3. You’re Low on Refrigerant: When Coolant Levels Drop

HVAC units rely on refrigerant to cool the air before circulating it throughout your home. If your system is low on refrigerant, it can result in warm air blowing from the vents. Low refrigerant levels are often indicative of a leak within the system, which requires immediate attention from a trusted HVAC professional. Attempting to fix refrigerant issues on your own can be risky and may lead to further damage. It’s important to understand that this is not a DIY fix. Refrigerant leaks can be complex and require specialized equipment and expertise to locate and repair. Contact a reputable HVAC technician, from a reputable air conditioning service company, who can assess your system, identify any leaks, and perform the necessary repairs. Remember, addressing refrigerant issues promptly can help prevent further damage to your unit and ensure efficient cooling performance.

4. Your Evaporator Coils Are Dirty: The Importance of Regular Maintenance

Evaporator coils play a vital role in the overall efficiency of your HVAC system. Over time, these coils can accumulate dirt, dust, and other debris, obstructing proper airflow and hindering cooling performance. It is recommended to include coil cleaning as part of your annual air conditioner tune-up to keep your unit running smoothly.

The evaporator coils are located inside your HVAC unit, and their primary function is to absorb heat from the air passing over them, facilitating the cooling process. However, as time goes by, these coils can become coated with dirt, dust, and other pollutants. This buildup restricts airflow, impairs heat absorption, and reduces the efficiency of your HVAC system. To prevent such issues, a professional central air technician can effectively clean the coils, removing any accumulated debris and ensuring optimal performance. By addressing this maintenance task, you can extend the lifespan of your unit and maintain efficient cooling throughout the summer months.

5. Your Condenser Coils Have Debris: Clearing the Path for Cool Air

Just as the indoor evaporator coils require unrestricted airflow, the outdoor condenser coils also need ample space for efficient operation. The condenser unit of your HVAC system is typically located outside your home and is responsible for releasing the heat collected from the indoor air. To perform this task effectively, the condenser coils need to have unobstructed airflow. Over time, outdoor debris such as leaves, grass, and dirt can accumulate on the coils, impeding proper heat dissipation. To ensure efficient cooling, it’s essential to maintain a two-foot clearance around the condenser unit. Regularly inspect the area and remove any debris that might have accumulated. Additionally, trim any nearby bushes or vegetation that could hinder airflow. By keeping the condenser coils clean and the surrounding area clear, you can help your HVAC unit operate optimally, providing you with reliable cooling when you need it most.

Taking proactive measures to keep your HVAC unit in excellent condition is essential for staying cool and comfortable during the summer months. By double-checking your circuit breaker, ensuring your thermostat is working correctly, addressing low refrigerant levels, cleaning your evaporator coils, and maintaining clear condenser coils, you can optimize your HVAC system’s performance. Remember, regular maintenance and professional tune-ups are key to preventing issues and maximizing efficiency.
