Summer in Indiana is showing no signs of slowing down, and we’re not the only ones feeling it! Your HVAC system is feeling the strain of keeping your home and family cool during these brutally humid summer days.
As the heat continues, maintaining a fully functional HVAC system is crucial for not only your comfort, but your safety too.
Prevention is Key to Avoiding HVAC Failures
The last thing you want is for your air conditioning to break down in the middle of a heatwave. In order to prevent that from happening, you’ll want to understand the most common causes of HVAC system breakdowns.
Learning how to prevent these common HVAC problems can help ensure your system runs smoothly all season long.
Common Causes of HVAC System Breakdowns and How to Prevent Them
Keeping your HVAC system in good shape is key to preventing a failure during the hottest summer months. If DIY solutions and maintenance feel overwhelming to you, you can always call a pro! That being said, there are simple ways to keep your HVAC system running smoothly to avoid a costly (and uncomfortable) breakdown.
Here are some key issues and tips to keep your HVAC system in top shape:
1. Dirty or Clogged Filters
Cause: One of the most common reasons for an HVAC system to fail is due to dirty or clogged filters. When filters are not changed regularly, they become clogged with dust, dirt, and debris, reducing airflow and causing the system to work harder than it needs to.
Prevention: Change your HVAC filter every 1-3 months, especially during peak usage seasons. This is a simple maintenance task that can improve your system’s efficiency and extend its lifespan.
2. Refrigerant Leaks
Cause: Refrigerant is an essential part of the cooling process in your HVAC system. Leaks in your refrigerant can occur due to general wear and tear, but cause the system to lose its cooling capacity and overheating.
Prevention: Regularly inspect your HVAC system for leaks and ensure that you maintain the proper levels of refrigerant. If you notice a decrease in cooling performance or hear hissing sounds, you’ll need to contact a professional technician to diagnose and fix the issue.
3. Thermostat Issues
Cause: Faulty or incorrectly set thermostats can lead to HVAC system malfunctions. If the thermostat isn’t accurately measuring the temperature or is not programmed correctly, the system may run inefficiently or not at all.
Prevention: Regularly check and calibrate your thermostat to ensure it is functioning correctly. Consider upgrading to a programmable or smart thermostat for even better control and energy efficiency.
4. Electrical Problems
Cause: HVAC systems rely on various electrical components to operate. Issues such as loose connections, faulty wiring, or blown fuses can cause the system to shut down unexpectedly.
Prevention: Schedule annual HVAC maintenance to have a professional inspect and tighten electrical connections, check for damaged wiring, and replace any faulty components.
5. Lack of Maintenance
Cause: Neglecting your HVAC system of regular maintenance can lead to various problems, from dirty coils and blocked drainage to worn-out parts. Over time, this can cause the system to break down and decrease its lifespan drastically.
Prevention: Schedule regular maintenance checks including inspections, cleaning, and tune-ups to identify and address potential issues before they become major problems.
6. Frozen Evaporator Coils
Cause: When evaporator coils freeze, it’s often due to airflow issues or low refrigerant levels. This can cause the system to overheat and shut down.
Prevention: Make sure your system maintains proper airflow by keeping filters clean and addressing any ductwork issues. Regularly check refrigerant levels and have a professional inspect the system if you notice ice buildup on the coils.
7. Blocked Condenser Unit
Cause: The outdoor condenser unit can become blocked by debris such as leaves, dirt, and grass, hindering its ability to release heat and causing the system to overheat.
Prevention: Keep the area around the condenser unit clear of debris and vegetation. Regularly clean the unit and ensure there is at least two feet of clearance around it for proper airflow.
Let’s Get Through Summer Together, Indiana!
Indiana’s humid summers can put significant strain on your home’s HVAC system, which means that performing regular maintenance is even more critical. High humidity levels can lead to excess moisture in the system, causing issues like mold growth and rust.
Ensuring your system is dehumidified and well-maintained can help prevent these problems and keep your family cool all summer long.
Understanding the common causes of HVAC problems and taking proactive steps to prevent them can save you from costly repairs and ensure your home remains comfortable throughout the summer. Regular maintenance, timely inspections, and addressing minor issues before they escalate are key to keeping your HVAC system running smoothly.
