If an HVAC were human, refrigerant would be the blood of your HVAC. Without enough refrigerant your system will not cool your facility properly. Low levels of refrigerant can damage your HVAC severely, just like if blood count is low it causes major damage to your whole system. Here are causes of low refrigerant and what to do to get it back to running normally.
Your facility is taking forever to cool off
Does it take longer than usual to cool down your facility? You are most likely low on refrigerant. This happens because it is what absorbs the
heat in the air. Without enough of it, it can’t absorb heat to cool the air properly. Just consider it the sponge for heat.
High electric bills
If your HVAC isn’t running like it should you will see that reflects on your next few electric bills before you probably realize there is an issue. If your bill increases, it may be time to check and increase your freon in your machine. Preventative maintenance works in the long run so be sure to check your levels.
Your system is blowing warm air
If your system is very low on refrigerant, your vents will be blowing warmer air than usual. This sign of the health of your HVAC is usually the first sign of a major problem. Be sure to give your facility maintenance company a call for reactive work.
It could be possible that your HVAC has a mild to severe refrigerant leak. You will have to do a diagnostic check on the system. If a leak is found it should be repaired, if it is possible, before refrigerant is added. Adding it to an unfixed unit will just cause the same results and the problem will continue. You can usually hear when there is a leak by the bubbling the HVAC makes.
If you see ice in your outside machine, the part with the fan, on the copper pipes that means you are low on refrigerant. Backflow of refrigerant in your lines causes the liquid to get too cold making the inside of the unit’s evaporator leads to the moisture surrounding the line to freeze.
Eventually the freezing will make its way to the heart of your HVAC, the
compressor. When this happens, it converts to thousands of pounds of hydraulic pressure and you are at risk of your plates, valves, and rods breaking. Compressors are expensive to replace, and if your warranty is past the date, you will likely have to replace the entire HVAC unit.
What To Do Next to Fix the Problem
If you think your HVAC is low on refrigerant, with maybe a leak or something more serious it is time to call a professional to diagnose the issue. AAFM Facility Maintenance is standing by to help create a preventative HVAC plan or for any of your facility needs.
