The Top 7 A/C Repair Problems
Summer is in full swing and that means one thing for many people – it’s time to turn on the air conditioner! If your A/C is giving you problems, don’t worry. We’re here to help. In this article, we will discuss the top 7 A/C repair problems and how to fix them.
The Top 7 A/C Repair Problems
It’s important to schedule regular maintenance and tune-ups with a reputable AC service provider to get the most out of your air conditioning. Additionally, it’s important to understand the most common air conditioning issues so that you can take preventative measures against costly repairs. Here are the top seven A/C repair problems, according to experts:
1. Leaking refrigerant
This is one of the most common A/C repair problems. If your unit is leaking refrigerant, it’s likely due to a problem with the evaporator coil or a faulty compressor. Either way, this is a problem that should be addressed by a professional as soon as possible.
Cause: Over time, the AC system’s pipes and connections tend to deteriorate, resulting in refrigerant leaks. Water leaks usually occur due to blocked drainage pipes or defective condensate pumps.
Solution: Turn off the unit and call our experts straight away if you discover a refrigerant leak. Low refrigerant levels can harm the compressor, which is one of the most expensive components to replace. Regular maintenance checks can help identify problems, and our certified technicians can top off refrigerants as needed.
2. Dirty air filter
A dirty air filter can block airflow and cause your A/C unit to work harder than it needs to. This can lead to several problems, including decreased efficiency and increased wear and tear on your unit. Be sure to check your air filter regularly and replace it as needed.
The build-up of dirt and debris can block airflow and cause your system to work harder than it needs to. This can lead to increased energy bills and premature wear on your A/C unit.
The air filter should be replaced at least once every three months, but it may need to be replaced more often if the unit is in use frequently. A dirty air filter can cause the unit to overwork and eventually break down.
3.A/C won’t turn on
It’s annoying to get up in the morning and discover that the air conditioner isn’t working. Even if you set the thermostat to a lower setting, the air conditioner will not turn on.
Cause: This problem can occur when a circuit breaker has been tripped. Faulty thermostats or unsecured wiring are two other possibilities.
Solution: Don’t attempt to repair wiring yourself. Only experienced HVAC specialists use special diagnostic tools to identify any electrical issues.
4. Frozen Evaporator Coil
The air conditioner’s evaporator coil is filled with refrigerant and is responsible for absorbing the heat from the air like a sponge. Those coils need warm air circulating them to work properly.
Cause: A blockage in the system, such as a clogged vent or duct, dirty filters, or broken parts, can cause inadequate airflow. To maximize airflow and interior air quality, a clean air filter is necessary.
Turn off the air conditioner and set it to “on” on your thermostat, allowing the fan to blow on the ice. Check for dirt and debris in the air filter and evaporator coil. Clean it up if necessary. Look for blockages or disconnections in the ductwork, as well as any registers that are stuck open. If your AC continues to freeze, there’s a good chance it’s because you’re running low on refrigerant (a leak) or the refrigerant line has been damaged.
5. Air Conditioner Blowing Hot Air
You’re sitting in the middle of a sweltering summer and find out your air conditioner is producing excessive heat. Check your thermostat first and make sure you haven’t switched it to “heat” or “fan.” This should solve your problem if you set it to “cool” or “auto.” This is an easy mistake that can be made by inadvertent finger slipping or contact.
Cause: A dirty air filter, a blockage in the ducts, or debris blocking the compressor from cooling may all be signs that your heat isn’t working. It’s also likely that the refrigerant levels aren’t sufficient.
Solution: To avoid blockages, change the air filters every month or two and have your ducts cleaned at least once a year. Always have a professional look for leaks before adding refrigerant to AC units. You won’t be sorry if you do this.
6. Weird Smells Emitting from the AC
A burning odor is one of the first signs of an AC problem. Some homeowners report a musty aroma as well. You might notice these odors coming from the vents or when you’re near the main air conditioner.
Cause: The motor may have a wiring problem if you detect electrical odors. If your air filters are clogged, the system may overheat, causing burn smells. Mildew odors are caused by poor drainage.
Solution: If you notice a burning odor, turn off the air conditioner right away. Examine the air filters. If they appear to be filthy, replace them. Scheduling regular duct and AC unit cleaning is an excellent method to prevent these odors. Musty scents may also be eliminated using our system maintenance services.
7. Noises from the Air Conditioner
Sounds you’ve never heard before should raise a red flag. Strange vibrations, squealing, or grinding noises indicate that something is wrong and must be addressed.
Cause: Grinding noises are frequently the consequence of a misaligned or worn belt. Grinding sounds are especially hazardous to air conditioners since they typically indicate problems with motor bearings.
Solution: These loud noises will go away once the underlying issue has been addressed. During our normal maintenance service, our experts check belts and lubricate bearings to ensure that the compressor motor is protected.
