Have you ever wondered what goes into a heating or air conditioning system for a large office building or another large building like a mall or a school? My name is Evelyn, and I am an HVAC architect. I design heating and air conditioning systems for large, corporate buildings. Making sure that a large building with many rooms or offices is efficiently heated and cooled is a very large job and is much more complicated than simply heating or cooling a home. This blog will educate the reader on how heating and cooling jobs this large are designed and completed.
Low refrigerant charge is among the issues which require timely air conditioning system repair. This may happen if, during installation, the technicians undercharged the system instead of putting in the amount of refrigerant specified by the manufacturer. Similarly, your system may end with a low refrigerant charge due to leakages.
It is crucial to schedule air conditioning system repair as soon as possible when you have a low refrigerant charge. If you wait too long, you may end up dealing with the following issues.
A tell-tale sign of low refrigerant levels requiring air conditioning system repair is reduced cooling. This is expected as the lesser the refrigerant available, the lesser the amount of heat your unit will be able to absorb from your spaces.
In severe cases where the refrigerant levels are too low, your system may not produce any cold air. Instead of reduced cooling, you will have no cooling whatsoever.
Even before you notice the reduced cooling, you will not miss the noise coming from your unit. There are several reasons why your unit may produce noisy operation, including refrigerant leaks. Call an air conditioning repair technician if you hear a bubbling or hissing sound from your system's condenser.
You can expect a bubbling sound when the refrigerant is leaking in its liquid state. However, you will hear a hissing sound if the refrigerant is leaking out in its gaseous state.
Frozen Evaporator Coils
Low refrigerant levels will leave the refrigerant lines with low pressure. When this happens, the evaporator coil temperature will drop drastically below the freezing point. Moisture will quickly freeze along the evaporator coils.
In this case, you will need to turn off your air conditioner, so the frost on the evaporator coil thaws out. Having to do this every often can be quite an inconvenience. However, avoid scraping off the frost as this may only damage the coil.
Higher Energy Bills
The reduced cooling that comes with low refrigerant levels will force your system to work much harder and for longer to deliver the cooling you need for your spaces. The longer your system runs, the more energy it draws, and you will have a higher bill at the end of the month.
Different air conditioning system repair needs, if left unattended, can leave you dealing with discomfort in your spaces and higher energy bills. Be sure to call a repair technician as soon as possible when you notice signs of low refrigerant charge.
