This might be the most valid (and heated) question of the summer: Why is my central air conditioner blowing warm air?
If your AC is blowing warm air, you have a problem. However, the problem may not always simple to spot. Understanding the parts of your air conditioner can help you to identify why it could be blowing warm air. Perhaps the compressor, condenser, expansion valve, fan, coil, filter or drainage system is damaged and need replacement or maybe they’re just dirty and need a tune-up. The best way to find out is to have one of PFO’s certified HVAC professionals assess the problem.
3 Top Reasons Your AC is Blowing Warm Air
Contents
1) Refrigerant Problems
This is the most common cause for warm air in the AC unit. AC unit refrigerants can be dangerous for homeowners to handle. How do you know if your AC unit has refrigerant problems? Sometimes, you can spot R-22 leaks of fluid in or around the unit. Leaks are unpredictable, so they are often one of the first places technicians will troubleshoot. Most leaks require some internal repair, as well as R-22 replacement to ensure that the unit will start blowing cool air again.
2) Broken Thermostat
Don’t be alarmed, but your thermostat might also be to blame. Before you panic about your air conditioner blowing warm air, double-check your thermostat settings. After winter, you may have forgotten to change the setting from “warm” to “cool.” However, your thermostat might also need re-calibration or repair. For example, the numbers might read at 78 degrees, but the air feels like it is about 85 degrees. Troubleshoot by checking the settings for accuracy, and then assess the air coming from the unit. If you still have warm air, you will need to call Princeton for air conditioning repair.
3) Compressor Problems
The AC unit’s compressor has one of the toughest jobs in the AC system. It uses R-22 gases and converts it into a high-pressure gas that is then sent to the condenser. The compressor is a keystone within the unit itself, and if it is malfunctioning (or damaged), the unit simply won’t work correctly. Even professional AC repair technicians need to take precautions when diagnosing this problem, however, most compressors can last up to 10 to 20 years. Compressor problems are usually apparent in older homes with older AC units. Electrical failures, overheating, and other factors over time can contribute to compressor damage. If badly damaged, the costs to replace it might outweigh the benefits of simply buying a new unit! Consult with your Mercer County AC repair company, PFO, for advice.
