A common problem with an HVAC system is when all you feel is warm air coming out of the vents when you have your air conditioning on. This tends to happen during the most inconvenient times, such as when it's an incredibly hot day or you plan on having guests over at your home. You'll quickly find yourself calling a local HVAC repair technician to fix your air conditioning. When dealing with HVAC repair, there are two things you need to understand when the HVAC technician is telling you about the problem.
Understand What "The Charge" Means
Air conditioners require a certain amount of refrigerant in the system for it to properly function. Running an air conditioner that doesn't have refrigerant will cause your home to be hot. The unit is unable to cool the air, and it just circulates warm air throughout the entire house. Running an air conditioner without refrigerant can also cause damage to your air conditioner as well.
Your HVAC technician may refer to the problem with the refrigerant as the unit's charge. Saying your air conditioner needs to be charged is the same as saying it is low on refrigerant. Fixing the problem involves finding out why the unit is low on refrigerant. There could be a leak somewhere in the refrigerant line causing it to escape, which would require the line to be fixed before more refrigerant is put into the system.
Once the leak is fixed, the air conditioner will then be charged by refilling it with the proper amount of refrigerant.
Understand What "The Condenser" Is
Another aspect of your HVAC system that the technician will want to look at is the condenser. This is the unit that is installed outside your home that contains the coils that chill the refrigerant. A common problem with the condenser is that the fins have become blocked with debris. This causes the unit to be unable to cool itself down as efficiently as it could, which can cause damage to the internal parts that power your air conditioning.
Part of the repair process will start with making sure your condenser is clean and has clear airflow throughout the entire unit. If this is not done, you may inadvertently cause the same damage to your air conditioner when it continues to run hot due to poor airflow.
If you ever have questions about the terms used when describing problems with your air conditioner, do not hesitate to ask your technician for more info. For more information, contact a business such as D & W Heating & Air Conditioning Inc.
