The Chilling Truth: Why Your AC Unit is Freezing Up
As temperatures rise, the last thing you want is for your air conditioner to stop cooling. However, if your AC unit starts blowing warm air or even turns into a block of ice, you’re dealing with a frustrating problem: a frozen AC unit. Not only does this leave your home uncomfortable, but it can also lead to costly repairs if left unchecked. So, why does this happen, and how can you prevent it? Let’s break it down. What Happens When Your AC Freezes Up? When your AC freezes, it’s a sign that something is wrong with the system. You may notice frost or ice building up on the evaporator coils, which restricts airflow and prevents the unit from cooling your home properly. As a result, your system struggles to maintain the desired temperature, leading to poor performance and higher energy bills. Common Causes of a Frozen AC Unit Several factors can cause your AC unit to freeze up, but here are the most common ones: Low Refrigerant Levels Low refrigerant is one of the main culprits behind a frozen AC. When the refrigerant level drops, the evaporator coils become too cold and start forming ice. This is often the result of a leak, which requires professional repair. If you notice warm air coming from your vents or hear a hissing sound, it’s a sign that your refrigerant may be low. Dirty Air Filters Air filters are crucial in maintaining airflow throughout your AC system. Over time, filters can become clogged with dust and debris, causing airflow to slow down. Without proper airflow, the coils can freeze. Regular HVAC tuneups, which include changing air filters, can help prevent this issue. Blocked or Dirty Coils If your evaporator coils are dirty or blocked, they won’t be able to absorb heat properly. This can cause the temperature to drop too low, leading to ice buildup. Keeping your coils clean is an essential part of HVAC preventative maintenance that can extend the life of your system. Poor Airflow (Blower Fan Problems) A malfunctioning blower fan can also result in low airflow, causing the coils to freeze. If the fan is not circulating air properly, the cooling process becomes inefficient, and your AC can freeze up. Thermostat Issues or Incorrect Settings Sometimes, a faulty thermostat or incorrect settings can cause the unit to run too cold. If you’ve accidentally set your thermostat too low, it may lead to the formation of ice on the coils. How to Prevent Your AC from Freezing Up Preventing a frozen AC unit is all about proactive care. Regular HVAC preventative maintenance is key to keeping things running smoothly. Here are some simple steps to keep your system in check: Change air filters regularly to ensure proper airflow. Schedule an HVAC tuneup at least once a year to keep your system in optimal condition. Keep the thermostat at a reasonable setting to avoid freezing your system. Clean the coils and check for any dirt or debris that might obstruct airflow. Ensure your system is properly sized for your home to prevent overworking the unit. What to Do if Your AC Is Already Frozen If your AC unit is already frozen, turn it off and let it thaw. This will help prevent further damage. Once the ice has melted, check the air filters and airflow. If the problem persists, it’s time to call a professional HVAC technician to assess and repair the issue. When to Call a Professional If your AC keeps freezing up, it’s a clear sign that something more serious is wrong. Whether it’s a refrigerant leak, a damaged blower fan, or another complex issue, a professional HVAC technician can diagnose and fix the problem. HVAC tuneups and inspections can help spot potential issues before they turn into costly repairs. Contact PRK Services if you need help with your AC unit.

The Importance of Regular HVAC Tune-Ups
Your HVAC system works tirelessly to keep your home comfortable all year round. From blazing summer days to chilly winter nights, it ensures you and your family stay cozy. However, like any machine, your HVAC system needs regular care to keep running smoothly. That’s where an HVAC tune-up comes in! Here’s why HVAC preventative maintenance isn’t just a good idea but an essential part of homeownership. Benefits of Regular HVAC Tune-Ups Enhanced Energy Efficiency An HVAC tune-up helps keep your system running as efficiently as possible. Dust and debris can collect over time, resulting in clogged filters and coils. This issue forces your HVAC unit to work harder. This extra effort requires more energy, which translates to higher utility bills. With regular tune-ups, your system stays clean and optimized, using less energy and saving you money. Extended Lifespan of Equipment Preventative maintenance for your HVAC system can add years to its life. Tune-ups address minor issues before they become big problems that could lead to costly repairs or premature replacement. Just as regular oil changes keep a car running longer, HVAC tune-ups help extend the life of your heating and cooling equipment. Improved Indoor Air Quality Your HVAC system doesn’t just control temperature—it also filters and circulates the air inside your home. When filters are dirty or components are clogged, your system can start circulating allergens, dust, and other particles. Regular HVAC tune-ups improve indoor air quality by keeping these contaminants out, which is especially important for households with allergies or asthma. Consistent Comfort Levels A well-maintained HVAC system provides steady and reliable temperature control. When your system is in good shape, it heats and cools your home evenly, helping prevent those uncomfortable hot or cold spots. Preventative maintenance ensures consistent airflow and comfort throughout your home. Early Detection of Potential Issues One of the biggest advantages of a regular HVAC tune-up is catching small issues before they turn into big headaches. For instance, a minor refrigerant leak can quickly turn into a costly problem if left unchecked. During a tune-up, HVAC technicians can identify and address these small issues early, saving you from surprise breakdowns and major repairs down the road. Environmental Benefits Maintaining an energy-efficient HVAC system isn’t just good for your wallet; it’s also beneficial for the environment. Efficient systems consume less energy, reducing your carbon footprint. Plus, tune-ups can prevent refrigerant leaks that could harm the environment, making HVAC preventative maintenance a green choice. Consequences of Skipping Regular HVAC Tune-Ups Skipping HVAC tune-ups can lead to higher energy bills, increased risk of breakdowns, and even potential health risks from poor indoor air quality. A neglected system has to work harder to perform basic functions, which not only raises your monthly costs but can also wear out the equipment faster. Without preventative maintenance, your HVAC system may need more frequent repairs and could require a replacement sooner than expected. Signs Your HVAC System Needs a Tune-Up If you’re noticing higher energy bills, unusual noises, inconsistent temperatures, or reduced airflow, it may be time for a tune-up. These signs suggest your system is struggling and could benefit from a professional inspection. Investing in regular HVAC tune-ups is one of the smartest steps you can take as a homeowner. Not only will it help your system run more efficiently, but it also ensures your comfort, saves on repair costs, and contributes to a healthier environment. If it’s been a while since your last tune-up, consider scheduling one with PRK Services to keep your home’s HVAC system in top shape year-round.
