Summer is here, and if you’re like most people, you’ve probably relied on your air conditioner to keep you cool. But what happens when your AC isn’t working correctly? Not only is it uncomfortable, but it can also be an expensive problem to fix. In this blog post, we’ll go over common causes of air conditioner problems and how you can fix them.
Dirty Air Filter
Dirty filters are one of the most common reasons your AC isn’t working correctly. Air filters should be replaced or cleaned regularly. Clogged filters will restrict airflow, making your AC work harder than usual. This not only reduces efficiency but also puts extra strain on your unit, potentially leading to more significant issues. A dirty filter has a negative impact on your health should mold, bacteria or pollen build up inside the unit, so you want to take this task on yourself and make sure that you routinely remove the filter and clean it thoroughly with soap and water.
Solution: Check and change filters regularly, at least every 3 months or as recommended by the manufacturer.
Thermostat Malfunctions
The thermostat is responsible for regulating temperature settings. A malfunctioning thermostat can cause your AC to stop working altogether. You should troubleshoot by checking the batteries and resetting the thermostat. If the temperature seems off, make sure the thermostat isn’t exposed to direct sunlight, which may cause it to register the wrong temperature.
Solution: If the batteries are good and resetting doesn’t work, it’s time to call an HVAC technician.
Refrigerant Leaks
Refrigerant leaks can cause your AC to blow hot air. Low refrigerant levels or a refrigerant leak can also be hard on AC systems, causing them to run erratically. Leaks can be a severe problem, and it’s best to contact an HVAC professional to repair it. The EPA regulates refrigerants, and it’s hazardous to handle.
Solution: If you suspect a refrigerant leak, stop using your AC and call a professional right away.
Frozen Coils
Frozen coils will restrict airflow and cause your AC to stop working. This can be caused by poor airflow or a dirty condenser coil. If your coils are frozen, it’s best to turn off your AC and let the ice melt before restarting. In some cases, a dirty evaporator coil could also cause the air conditioner to turn on and off repeatedly.
Solution: To fix this, check and replace your air filters, clean your outdoor unit, and check your evaporator coil. If you’re unsure of the cause, it’s best to call a professional.
Blocked Drainage
Water moisture is a byproduct of air conditioning. Your AC unit uses a condensation line to remove excess moisture. When blocked, the buildup of water can cause severe damage to your AC and home.
Solution: Clean your drains of blockage regularly. Check and clear your condensation line regularly, especially during periods of high humidity.
Faulty Capacitors
Capacitors are responsible for the starting power of your air conditioning system. A faulty capacitor can cause AC problems like poor airflow, intermittent function, or complete shutdown.
Solution: If your AC is exhibiting any of these symptoms, call a professional to replace the faulty capacitor.
Dirty Condenser Coils
Dirty coils will reduce the efficiency of your AC and can cause it to stop functioning. The outdoor unit of your AC system is exposed to the elements and can quickly accumulate dirt, debris, and grime.
Solution: You can clean your condenser coils yourself with a garden hose, but it’s recommended to have an HVAC professional do it for you.
Electrical Issues
Electrical faults in your air conditioning system can lead to all sorts of issues. Examples of such include tripping circuit breakers, frequent power surges, faulty wiring, and malfunctioning relays.
Solution: If you’re experiencing any electrical problems with your AC, call an electrician or HVAC professional for help.
Lack of Maintenance
Without regular maintenance, your AC will eventually experience problems and break down. It’s essential to have a professional perform annual check-ups and inspections to keep your system running efficiently.
Solution: Schedule regular maintenance for your air conditioner to avoid costly repairs in the future.
Worn Out Contactors
A contractor is responsible for allowing power into your air conditioning system. Wear and tear can cause the contactor to malfunction, causing intermittent DC power or no power at all.
Solution: If your AC is turning on and off frequently, or not at all, it’s time to have the contactor checked and replaced if necessary.
Fan Motor Problems
If your AC fan isn’t working correctly, your unit won’t be able to circulate cool air. This is typically caused by a faulty motor or loose fan belt. If the fan doesn’t run, try resetting the furnace circuit breaker. If the fan still won’t start, call a pro
Solution: If you suspect any issues with your AC fan, it’s best to have a professional inspect and replace parts if necessary.
Evaporator Coil Leaks
Evaporator coils can sometimes develop leaks, leading to a Freon shortage and inadequate cooling. This is a complex issue that requires an HVAC professional to fix.
Solution: Have your evaporator coils checked and repaired by a professional to prevent further issues.
When to Hire an Air Conditioner Repair Company
Some AC problems are simple enough to fix on your own, such as replacing filters or resetting the thermostat. Try cleaning or replacing the air filter before contacting a professional for air conditioner repair service. However, if you’re unsure of the cause or unable to fix it yourself, it’s best to call a professional air conditioner repair company. They have the knowledge and expertise to diagnose and fix any issues with your AC efficiently and effectively. AC repair can be challenging and dangerous, so it’s best to leave it to the professionals. It will save you time, money, and hassle in the long run.
HOW OFTEN SHOULD A HOME AC UNIT BE SERVICED?
It’s recommended to have your home AC unit serviced at least once a year. This annual check-up should include cleaning, inspecting, and any necessary repairs or replacements. However, if you’re experiencing issues with your AC, it’s best to schedule a service call as soon as possible. Regular maintenance will not only keep your AC running smoothly but also help prevent potential problems and costly repairs in the future. Make sure to follow the manufacturer’s recommendations for maintenance intervals and consult with a professional if you have any concerns or questions about your AC unit.
