Are you getting central air conditioning for the very first time? While the hope is that the unit will run smoothly for years to come, because it is brand new, there will eventually come a time where you need to have the unit repaired. Here are some common repairs that you can expect to have done, as the unit starts to break down.
Refrigerant is essential to your central air conditioning, since it helps remove the heat from the air in your home. Unfortunately, the refrigerant line may experience an unexpected leak that causes some serious problems. With low refrigerant in the system, you'll experience warm air due to the evaporator coils not being able to remove the heat. Those coils can also freeze and cause short cycling issues. You'll need to have an HVAC technician locate the leak in the refrigerant line, repair it, and recharge the system with more refrigerant. This is something that is likely far outside your skill set, when it comes to doing home repairs on your own.
Frozen Evaporator Coils
Those evaporator coils won't only freeze, if there is a refrigerant leak. Sometimes the coils can freeze if they are very dirty. Warm air can be an indication that you need to clean the evaporator coil so that it is free of debris and can operate normally.
Clogged Condensate Drain
All of that moisture that comes off the evaporator coil will go into a drain pan and into the condensate drain. If you have a dirty air filter that has not been trapping the dirt and debris in the air handler, that dirt can get into the condensate drain and cause a clog. You may end up with water on your floor from a condensate drain that has overflowed or an air conditioner that stops working due to a float indicator telling the air condition to shut down, because the water levels are getting too high. If you can't figure out how to get to the condensate drain, you'll need to hire an HVAC technician to repair it for you, such as those at Nova Air Conditioning & Heating.
The outdoor compressor unit sees a lot of wear and tear over the years, and you can eventually run into a problem where the motor stops working. This may be due to overheating caused by restricted airflow to the unit or simply from being used often over the years. Again, a professional can inspect the motor in the unit and perform the necessary repairs to get it working again.
