Why Is My Air Conditioner Not Blowing Cold Air?

Are you tired of turning on your air conditioner on a hot day, but it only blows more warm air out of the vents? Rooter Hero Plumbing is here to make sure you stay comfortable all summer. If your AC isn’t cooling off your home, give us a call. Our team can help you find out what’s causing the problem so you can get things back on track quickly. Keep reading to find out what the most common causes are and what kind of solutions are available.

Dirty or Clogged Air Filters

Your AC might not be working simply because of clogged filters. Your air filters are supposed to trap dirt, dust, and airborne particles, but they can become blocked as time passes. If the airflow is restricted, the air conditioner will struggle with circulating cool air. This issue can put a strain on your system, so it’s important to check and replace your air filters every one to three months, depending on your usage and whether or not you have allergies or pets. It’s also a good idea to use high-quality filters that can boost your indoor air quality and improve your system’s performance.

Refrigerant Leaks or Low Levels

Refrigerant helps absorb the heat from inside your house so it can be released outdoors. If your system has low refrigerant levels because of a leak or other problem, it won’t cool the air effectively. Some signs that you have a refrigerant problem include ice buildup on your unit, hissing sounds, and warm air blowing from your vents. Low refrigerant levels are sometimes caused by leaks in the coils or connections. If you ignore these leaks, it could lead to more serious damage. Only professionals should handle refrigerants because there are environmental regulations and safety concerns surrounding their use. An HVAC specialist can locate and repair your leak and restore your system.

Faulty Thermostat Settings or Malfunction

The issue might not be with the AC at all but with the thermostat. If the settings are incorrect or the thermostat is damaged, it could prevent your air conditioner from working the way it needs to. If you have it set to “fan” rather than “cool,” for instance, the system might circulate the air, but it won’t cool it. Old or faulty thermostats can also stop communicating effectively with your system. If that’s the case, then upgrading to a smart or programmable thermostat could give you better control over temperatures. Another common problem is the placement of your thermostat. If it’s near a heat source or exposed to direct sunlight, then it could lead to inaccurate readings that cause your AC to run less efficiently. Make sure the thermostat is located in a central area of your home that’s well-shaded. If you’re not sure what’s going on with your thermostat, an HVAC company can diagnose the problem and fix the issue so you can stay cool.

Blocked or Dirty Condenser Coils

Dirt, leaves, and debris can accumulate on your coils inside the condenser unit, which is located outside. If this happens, then it will make it harder for your system to release the heat from inside your living space. Your HVAC system will work twice as hard, but it won’t get any cooler. Keep the area around your outdoor unit free of plant material for better airflow. It’s also a good idea to invest in routine cleaning and maintenance of your condenser unit so that your coils are free to do their job. Annual maintenance services from a qualified HVAC company will help you keep the indoor and outdoor components of your system in great shape.

Electrical Issues and Component Failures

Your HVAC system depends on a lot of different components to work properly, including motors, relays, and capacitors. If these parts start to fail, then your AC might stop blowing cold air. A failing capacitor might prevent your compressor and fan from starting, and wiring issues can disrupt the operation of your system. Routine inspections will help to catch any electrical issues or faulty parts early on before they cause too much trouble.

Frozen Evaporator Coils

It’s also possible that your evaporator coils are frozen. This issue can happen because of restricted airflow from dirty filters, low refrigerant levels, or blocked vents. If your coils freeze, then your system won’t be able to absorb heat, which causes warm air to blow from vents. If you notice any ice building up on your unit, turn off the AC system completely and let it thaw before restarting it. Persistent freezing is an issue that should be taken care of by an HVAC specialist in Sunnyvale, CA.

Preventive Maintenance and Professional Help

The best way to avoid the issues listed above is to prioritize routine maintenance by scheduling professional services before summer. Changing your air filters, cleaning around the outdoor unit, and investing in inspections can all help prevent problems. If your AC issues continue after troubleshooting, it’s important to work with a reliable HVAC company. They can conduct an inspection to find the cause of your trouble and will offer the best solution. Whether you need an air conditioning repair, furnace repair, or heating replacement, an experienced technician will have the equipment and skills needed to get your system back to working its best.
